COMBINATION SELF-CONTAINED BREATHING APPARATUS WITH HARNESS

FOR ESCAPE AND PRESSURE DEMAND TYPE C

SUPPLIED-AIR RESPIRATOR WITH AUTO TRANSFER

GENERAL DESCRIPTION

The Scott SKA-PAK AT respirator is approved by the National Institute for Occupational Safety and Health (NIOSH) as a pressuredemand, open circuit, combination self contained breathing apparatus for escape and Type C supplied-air respirator. The SKA-PAK AT is designed to prov ide respiratory protection during entry into, work in and escape from an objectionable, oxygen deficient and/or unbreathable (toxic) atmosphere.

This respirator is to be used only by persons trained in the use of the respirator and only in conjunction with an organized respiratory protection program. This respirator is not to be used under water, for interior structural fire fighting or for any other purpose not authorized by the organized respiratory protection program that applies specifically to the user.

The SKA-PAK AT is referred to as a “combination SCBA/hoseline” respirator because it operates as either a pressure-demand Type C supplied-air respirator when using air from a remote air supply system connected to the supply hose or as an escape only self-contained breathing apparatus when using air from the cylinder on the waist belt. The self-contained air supply may be used if the remote air supply system fails or when the air supply hose must be disconnected from the respirator for emergency escape from the work area. The SKA-PAK AT offers the additional advantage of an Automatic Transfer pressure reducer which can detect an interruption in the suppliedairline air pressure and automatically switch to the breathing cylinder while warning the user through the VIBRALERT® end of service time indicator in the facepiece mounted regulator.

Th e SKA-PAK AT is available in fi ve configurati o n s for use wit h th e follo w ing air supply cylinder s : 2216 psi 3 minute , 3000 psi 5 mi nute, 10 minute a nd 15 mi n ute, and 4500 ps i 10 min u te and 15 minute. These time durations represent NIOSH standards. Depending on activity and respiration rate, the actual duration may be much less than the NIOSH rating. Refer to the NIOSH approval label for the SKA-PAK AT, SCOTT P/N 59501 4-01, for the list of approved component part numbers.

When used as a Type C supplied-air respirator, the SKA-PAK AT must be supplied with clean, respirable air through the appropriate air supply hose.

The respirator consists of an adjusta b l e ha r n e s s t o s upport the re spirator o n the b o dy of th e user, a cylind e r and va lve assem bly for storing compressed breathing air, an automatic transfer pressure red u cin g reg u lat o r an d co u p lin g mo u nted on the cy lin d er va lve, a c y linder p r essure ga uge with an ELEC T RONIC al a rm, an airline connection hose, one or more segments of air supply hose to connect the resp irator to an air s upply sy stem, a h ose asse mbly connecting the pressure reducer to the facepiece mounted pressure demand breathing regulator with VIBRALERT®, and a full facepiece assembly.

The breathing regulator is equipped with a VIBRALERT alarm which warns t he user with both sound and feel that the supplied-air line pressure has been interrupted and that the reducer has automatically transferred to the cylinder air supply. The ELECTRONIC alarm will be actuated when the cylinder pressure drops below 90% (+/- 5%) of full rating, whether caused by breathing down the cylind er or to indicat e a malfunction or leak in the c ylinde r supply system. The ELECTRONIC alarm requires one 9V battery for operation. See the EL E CTRONIC ALA R M BATTERY R E PLACEMENT s e ction of this instruction.

The breathing regulator is also equipped with an air-saver/donning switch to prevent rapid loss of air if the air supply is turned on before donning the facepiece or if the facepiece is removed before disconne cting the supp ly hose or befor e turni n g off the air supply. The regulator is available with or without a quick disconnect fitting.

SCOTT full facepieces are available in a variety of styles and sizes. The facepieces may be readily detached from the breathing regulator to allow for the use of the best fitting and most comfortable size or style facepiece for an individual user. Fit testing per OSHA Standard 29 CFR Part 1910 or ANSI Standard Z88.2 requires testing in the negative press ure mode using equipment such a s a Portacou nt®

Respirator Fit Tester. For this, SCOTT facepieces require use

Plus of SCOTT Fit Test Adapter P/N 804057-01 or equivalent and appropriate negative pressure testing equipment. Mask Seal Kit P/N 80565501 may also be required to attain a proper fit. Each size facepiece may be equipped with a lens kit if the use of corrective spectacles is required.

Several self-contained air c ylinders are avail able for use with the SKA-PAK AT.

The airline air supply must be supplied with breathing air known to be suitable for human respiration at a pressure of 80 psig to 115 psig operation with a minimum flow rate of 200 liters per minute (lpm). Airline connection hoses used during Type C supplied-air respirator operation have one of five types of quick connect plugs and come in single- or dual-plug versions. Dual plug versions provide a facility for transition between redundant air supply hoses. On both the single and dual plug versions, a check valve in the pressure reducer prevents air flow from the respirator when the air supply hose is not in use or is disconnected from the respirator. On dual plug versions, each plug is individually checked to prevent depletion of the air supply when one (or both) of the air supply hoses is disconnected from the respirator or not in use.

Air supply hoses are available in several lengths. The maximum length and maximum number of segments of air supply hose allowed varies with the type of air supply hose. The air supply hoses and their limitations are covered in Table 1 and Table 2 of this instruction sheet.

DURATION OF THE RESPIRATOR

The SKA-PAK AT respirator is rated and approved by NIOSH as a combination self-contained breathing apparatus for escape and pressure demand Type C supplied-air respirator. The duration of this respirator, when used as a Type C supplied-air respirator, is limited only by the capacity of the air-supply system. The duration of this respirator during use as an escape only SCBA is limited by the capacity of the self-contained air supply cylinder on the waist belt. The cylinder's rated duration is marked on the cylinder. The user should not expect to obtain exactly the stated duration of breathing air during each use of the self-contained air supply cylinder. The user’s breathing rate may be more or less than the 40 lpm respiration standard used in the NIOSH tests. Depending on activity and respiration rate, the actual duration may be less than 1/2 the rated duration of the air supply cylinder. The length of time the self-contained air supply cylinder will continue to provide breathing air during any one use depends on such factors as:

1. The degree of physical activity of the user.

2. The physical condition of the user.

3. The degree to which the user's breathing is affected by excitement, fear or other emotional factors.

4. The degree of training or experience the user has with this or similar equipment.

5. Whether or not the cylinder is fully charged at the start of the use period.

6. The possible presence in the compressed air of carbon dioxide concentrations greater than .04% normally found in atmospheric air.

7. The atmospheric pressure; for example, if used in a pressurized tunnel or caisson at 2 atmospheres (15 psig gauge) the duration will be one-half as long as when used at 1 atmosphere; and at 3 atmospheres will be one-third as long.

8. Loose or improperly fitting facepiece.

9. Whether the purge valve is open.

10. The condition of the respirator.

THE HIGH PHYSICAL AND/OR EMOTIONAL

WARNING

LEVEL ASSOCIATED WITH EMERGENCY SITUATIONS TEND TO INCREASE BREATHING RATE AND TO DECREASE THE ACTUAL DURATION OF THE SELF-CONTAINED AIR SU P P LY. FA ILURE TO CONS I D E R TH E SE FACTORS MAY RESULT IN SERIOUS INJURY OR DEATH.

WARNING

DO NOT USE THIS RESPIRATOR IN A PRESSURIZED ENVIRONMENT. THE DURATION OF THE SELF-CONTAINED AIR CYLINDER ON THIS RESPIRATOR WILL BE SIGNIFICANTLY SHORTER IN A PRESSURIZED ATMOSPHERE AND MAY NOT PROVIDE ADEQUATE TIME FOR ESCAPE RESULTING IN SERIOUS INJURY OR DEATH.

WARNING

THE PURGE VALVE IS AN EMERGENCY CONTROL FOR USE ONLY IN THE EVENT OF A FAILURE OF THE MASK MOUNTED BREATHING REGULATOR. OPENING THE PURGE VALVE FOR ANY OTHER REASON WHILE THE RESPIRATOR IS BEING SUPPLIED WITH AIR FROM THE ESCAPE AIR SUPPLY CYLINDER COULD EXHAUST THE RESPIRATOR AIR SUPPLY IN AS LITTLE AS 2 MINUTES AND MAY RESULT IN SUDDEN TERMINATION OF BREATHING AIR WHICH COULD CAUSE SERIOUS INJURY OR DEATH.

FACEPIECE FITTING AND FIT TESTING

A respirator Quantitative Fit Test must be performed to ensure the correct respirator facepiece size has been selected and assigned to the user. It is the responsibility of the Respiratory Protection Program Manager or Safety Coordinator to assist the user in selecting the correct respirator size relative to the user’s facial features and dimensions. Fit Testing must be performed with any approved SCOTT accessories that will be used with the respirator installed, such as a communications device installed on the facepiece.

Respirator fit tests are explained fully in the American National Standard Practices for Respiratory Protection, ANSI Z88.10-2001 which is published by the American National Standards Institute (ANSI), 11 West 42nd Street, New York, New York, 10036, and in the Occupational Safety and Health Standards, OSHA 29 CFR 1910.134 Appendix A, which is published by the Occupational Safety and Health Administration (OSHA), 200 Constitution Avenue, NW, Washington DC, 20210.

Quantitative Fit Testing per OSHA Standard 29 CFR Part 1910.134 Appendix A, or ANSI Standard Z88.10-2001 requires testing in the negative pressure mode using equipment such as a Portacount Quantitative Fit Testing, SCOTT facepieces require use of the appropriate negative pressure testing equipment such as the Portacount Respirator Fit Tester along with the following:

• SCOTT 40mm facepiece Adapter, P/N 200423-01,

• a new SCOTT P100 Cartridge, P/N 052683,

• SCOTT Probed Fit Test Adapter P/N 805628-01 or equivalent probed

facepieces and the full range of sizes and styles

• Mask Seal Kit, P/N 805655-01

• the appropriate SCOTT communication device and mounting bracket

properly installed on the facepiece, if such an accessory will be used with the respirator.

• any other optional hood, eyeglass, or other accessory that will be used

with the respirator.

The size and style facepiece must be selected based on the user’s measured face size. For initial fitting, carefully don the facepiece and conduct a NEGATIVE PRESSURE LEAK TEST according to the instructions provided with the 40mm Adapter. Refer to the DONNING PROCEDURE section of this instruction for the procedure. Follow the DONNING PROCEDURE CARE- FULLY. If the selected facepiece does not pass the NEGATIVE PRESSURE LEAK TEST or does not fit securely without movement in the chin or chin cup area or the user experiences discomfort in the chin or throat, try the next nearest size, larger or smaller. After passing the NEGATIVE PRESSURE LEAK TEST, the facepiece size selected must be verified by successfully passing a respirator Quantitative Fit Test.

When fit testing for Open-Circuit, Pressure Demand Self-Contained Breathing Apparatus and/or Type C Pressure-Demand Supplied Air Respirator mode of operation (minimum Fit Factor equal to or greater than 500 minimum) appropriate negative pressure testing equipment must be used. You should use a P100 Filter, SCOTT P/N 052683 and the SCOTT P/N 805628-01 Fit Test Adapter.

When using a Portacount Respirator Fit Tester for Quantitative Fit Testing, TSI recommends that the level of particles in the ambient air must be between 5000 and 30000 particles/cm3. Refer to the Portacount Respirator Fit Tester user instructions for details including available Particle Generators to use with the Portacount Respirator Fit Tester if you have difficulty achieving the minimum level of ambient particle count required.

Test subjects must be in good health at the time of the fit testing. Smoking or eating less than 30 minutes prior to the test is prohibited. Any and all conditions that might interfere with a good face to facepiece seal must be addressed and corrected before performing the fit testing. Refer to the list of conditions in the DONNING PROCEDURES section of this instruction.

ALSO, THE ABSENCE OF ONE OR BOTH DENTURES CAN SERIOUSLY AFFECT THE FIT OF A FACEPIECE. USE OF AN IMPROPERLY FITTED FACEPIECE MAY LEA D TO EXPOSURE TO THE HAZARDOUS ATMOSPHERE WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.

Page 6 of 44P/N 595189-01 Rev A 4/10

Page 7

To verify the fit factor of the respirator, testing must incorporate an exercise regimen of normal daily activities. SCOTT requires the following set of fit test exercises, which are based on OSHA Standard 29 CFR Part 1910.134 Appendix A, and ANSI Z88.10-2001 with modifications.

Exercises are to be performed each for 60 seconds (except as noted) in a standing position during the test:

• Normal Breathing

• Deep breathing

• Turning head side to side

• Moving head up and down (look up/look down)

• Talking (read the Rainbow Passage)

• Grimace (15 seconds)

• Bending Over (touch toes) / Reach up (toward the ceiling)

• Normal Breathing (repeat)

Fit test exercises must be performed carefully as if the respirator was being used in a hazardous atmosphere. DO NOT bump the facepiece, filter, or adapter into the body through exaggerated motions. DO NOT talk except when directed to by the test administrator.

SCOTT requires that users of this respirator with an approved SCOTT facepiece, must achieve a Fit Factor of at least 500 for Type C PressureDemand Supplied Air Respirator mode of operation for use with their assigned facepiece style and size using the fit test procedures and exercise regimen stated above. If a Fit Factor of at least 500 cannot be achieved with any facepiece size or style, the user MUST NOT use this respirator.

If the respirator user passes a NEGATIVE PRESSURE LEAK TEST but DOES NOT pass a respirator Quantitative Fit Test, try the next nearest size, larger or smaller and repeat the NEGATIVE PRESSURE LEAK TEST and the Quantitative Fit Test. If leakage is still detected, either per these user instructions or the OSHA fit testing process, the use of Mask Seal Kit P/N 805655-01 may be required to attain a proper fit. Refer to the INSTALLATION AND USE INSTRUCTIONS, SCOTT P/N 89462-01, included with the Mask Seal Kit. After installing the Mask Seal Kit, repeat the fit testing process to confirm a proper fit.

Once the proper size is selected and assigned to the user following successful Portacount Respirator Fit Tester testing to achieve minimum Fit Factors required, the respirator user must perform and pass a NEGATIVE PRESSURE LEAK TEST as described in these instructions every time the facepiece is donned to ensure proper fit before using the respirator in a hazardous atmosphere.

During NEGATIVE PRESSURE LEAK TESTING, any facepiece leakage that is detected from other than the face to facepiece seal may indicate damaged or defective equipment. Remove the defective equipment from service and tag for repair by authorized personnel. Repeat the testing with equipment known to be operating properly.

IF A SATISFACTORY NEGATIVE PRESSURE LEAK TEST CANNOT BE PERFORMED, DO NOT USE THE RESPIRATOR OR ENTER THE HAZARDOUS ATMOSPHERE.

The facepiece alone does not provide any protection against a hazardous atmosphere without the use of the complete respirator.

A respirator Quantitative Fit Test must be routinely carried out as outlined above for each user of this respirator to determine or confirm the amount of protection that the respirator provides.

Periodi cal ly repeating the fit testing is required to identify any physical changes of the user (such as those listed in the DONNING PROCEDURES) which could effect the fit of the facepiece.

AIR SUPPLY SYSTEM REQUIREMENTS

Wh en t he r espirator is use d as a Type C supp lied air respirat o r I T IS THE RESPONSI B I LITY OF THE ORGANIZED RES P I RATORY PROGRAM UNDER WHICH THE RESPIRATOR IS USED TO PROVI D E A SUPPLY OF AIR THAT I S KNOWN TO BE CLEAN AND SAFE FOR BREATHING AND TO ENSURE THAT ALL OTHER REQUIREMENTS OF THE BREATHING AIR SUPPLY SYSTEM ST ATED BELO W ARE MET .

To use the SKA-PAK AT combination respirator as a Type C suppliedai r resp irator, it must be connected to a suitabl e suppl y of c lean breathing air through one or more segments of air supply hose. The air supply system must supply air containing no less than 19.5 percent oxygen and meeting the Grade “D” requirements of the Compressed Gas Association (CGA) Commodity Specification for Air G–7.1 available from the CGA, Inc. 1235 Jefferson Davis Highway, Arlington, Virginia, 22202.

In addition, the air must be dry, TO A DEW POINT OF -65°F / -54°C OR LOWER. If the breathing air is not dry, water may condense on the inside of the air supply lines or inside the respirator. In temperatures at or below freezing, +32°F / 0°C, the condensation may freeze inside the air supply lines or inside the respirator, possibly causing the flow of breathing air to be reduced or to stop completely.

NOTE

THE AIR USED IN THE AIR SUPPLY CYLINDER ON THE RESPIRATOR IS ALSO REQUIRED TO BE DRY TO A DEW POINT OF -65°F / -54°C OR LOWER.

The user’s breathing air volume requirement will vary depending on the activity being performed. The volume of air needed, expressed in liters per minute (lpm) at 1 atmosphere pressure, may range from less than 20 lpm when at rest to over 60 lpm during heavy work.

The air supply system must have the capacity to meet the user’s volume requ ireme nt for respiration while maintaining the req uired supply pressure of no less than 60 psig an d no more than 125 psig at the point of attachment of the respirator airline connection hose to the air sup ply system. If the pressure in the air supply system can exceed 125 psig, the air supply system shall be equipped with a pr e s s u r e- re le as e mechanism that will prevent the pressure at the point of attachment of the hose to the air supply system from exceeding 125 psig.

The coupling installed on the air supply system must match both the coupling installed on the supply hose and the coupling installed on the airline connection hose. The correct coupling must be directly installed on the air supply system. Adapters shall not be used. The couplings and fittings that mate with the couplings used on SCOTT air supply hose are available from SCOTT or from the coupling manufacturer. To determine what couplings are required, locate the SCOTT part number stamped on the end of the Airline Connection Hose Assembly located in the waist belt of the respirator. Refer to Table 2 on Page 29 of this instruction to determine the manufacturer and series number of the couplings.

The SKA-PAK PLUS combination respirator is NIOSH certified only when used with one of the types of hose with which it has been tested and approved. The types of hose are:

SCOTT 30010-Series air supply hose

• SCOTT 26370-Series air supply hose

• SCOTT 200820-Series air supply hose

• SCOTT 803904-01 air supply hose.

• SCOTT 30020-Series air supply hose and

• SCOTT 26369-Series air supply hose

ELECTRONIC ALARM BATTERY REPLACEMENT

The ELECTRONIC alarm requires a single 9 volt battery for operation. The LOW BATTERY YELLOW light on the ELECTRONIC alarm will appear when the battery must be replaced. When the LOW BATTERY YELLOW light begins flashing, the battery has suff icient power to continue normal operation for a period of time longer than the longest duration cylinder that may be installed on the SKA-PAK AT. However, after use of the respirator is terminated, the battery must be replaced before respirator use is resumed. Once the LOW BATTERY YELLOW light has been activated, the ELECTRONIC alarm will not initialize on start-up with a depleted battery and the RED warning light will not operate. Beyond a point, the YELLOW LIGHT will glow instead of flash. Replace the battery as follows:

1. Verify that the cylinder valve is closed and open the purge valve to relieve any pressure in the system. Close the purge valve.

2. Unscrew counterclockwise the single knurled screw on the cover of the ELECTRONIC alarm housing.

3. Open the housing cover and pull the cover gasket away from the cover to reveal the battery. See FIGURE 5A.

Be sure battery is properly oriented with the + pole of the battery

(the smaller male snap connector) positioned against the battery contact labeled + as shown in FIGURE 5B. As soon as the battery makes contact, the RED and YELLOW lights will flash alternately as they do for the initialization sequence. IF THE BATTERY IS INSTALLED INCORRECTLY, NEITHER LIGHT WILL FLASH.

6. With a fresh battery installed, fit the cover gasket back around the inside of the cover.

7. Close the cover and thread the knurled screw clockwise back in to secure the cover to the housing. Screw should be finger tight with the cover fully closed and the gasket evenly compressed.

8. Te s t the operation of the E L E C TRONIC a l a r m as outlined in the RE GULA R OPE R A TION A L IN S P ECTI O N se c t ion of th i s instruction.

9. In the case of an inope rative or malfunctioni ng ELECTRONIC alarm, respirator must be removed from service and sent to an authorized service center for alarm repair or replacement. DO NOT use a respirator with an inoperative or malfunctioning ELECTRONIC alarm.

REGULARLY INSPECT THE SKA-PAK AT

WARNING

Page 12 of 44P/N 595189-01 Rev A 4/10

Page 13

REGULAR OPERATIONAL INSPECTION

The following procedure shall be used when you first receive the respirator and for scheduled inspection of the respirator. All respirators shall be inspected after each use. A respirator not routinely used but kept for emergency use shall be inspected at least monthly. If damage or discrepancies are noted during the inspection of the respirator, remove the respirator from service and tag for repair by authorized personnel. Ensure that the cylinder valve is closed (push in and rotate the cylinder valve knob full clockwise). To vent any trapped air in the system, open the purge valve by rotating the red knob on the breathing regulator to the full counterclockwise position. Any trapped air will flow from the regulator. Close the purge valve by rotating the knob to the full clockwise position when air flow stops.

CYLINDER INSPECTION

NOTE

IT IS THE RESPONSIBILITY OF THE USER TO ENSURE THAT ALL DOT REQUIREMENTS FOR THE SELF-CONTAINED AIR SUPPLY CYLINDER ON THIS RESPIRATOR ARE MET AND MAINTAINED.

1. C heck the latest cylinder hydrosta tic test date to ensure it is

current. All cylinders used with SCOTT self-contained breathing apparatus must be visually inspected regularly and hydrostatically tested by a licensed cylinder retester in accordance with the appropriate US Department of Transportation (DOT) specification or the applicable DOT exemption. For a complete listing of retest date requirements, refer to the current revision of Safety Precautions for Air-Pak Cylinders, Scott P/N 89080-01, available on request from Scott Health and Safety. Composite cylinders (those cylinders utilizing fiber over wrap) must be tested in accordance with the DOT exemption status up to the maximum life of fiber overwrapped cylinders which , at the time of the publication o f this instruction, is 15 years from the date of manufacture. The date of manufacture marked on the cylinder is also the date of the first hydrostatic test. It is the responsibility of your organized respiratory protection program to arrange for visual inspection and hydrostatic testing of cylinders by a licensed retester.

2. Visually inspect cylinder and valve assembly for physical dam-

age such as dents or gouges in metal or in composite wrapping. Cylinders which show physical damage or exposure to high heat or flame, such as paint turned brown or black, decals charred or missing, pressure gauge lens melted or elastomeric bumper di s t o rted, and cyli n d ers which show ev idence of expo s u r e to chemica ls suc h as discol oration, cracks i n the cylin der or the composite wrapping, peeling of the outer layers of the composite wrapping and/or bulging of the cylinder wall, shall be removed from service and e mptied of compressed a ir. Refer to current applicable publications on compressed gas cylinder inspection available from Compressed Gas Association Inc. (703-413-4341), 1725 Jefferson Davis Hwy., #1004, Arlington, VA 22202.

3. Check the cylinder gauge for a “FULL” indication. If the cylinder

pressu re is less tha n “FULL,” replace the cylinder with a fully charged cylinder or have the cylinder charged to the full condition.

Proceed to HARNESS INSPECTION.

FOLLOW THE REGULAR OPERATIONAL IN-

WARNING

SPECTION PROCEDURE EXACTLY. IF THE PURGE DOES NOT ACTUATE AS DESCRIBED IN THIS INSTRUCTION OR ANY OTHER OPERATIONAL MALFUNCTION IS NOTED, DO NOT USE THE RESPIRATOR. REMOVE THE RESPIRATOR FROM SERVICE AND TAG IT FOR REPAIR BY AUTHORIZED PERSONNEL. FAILURE TO PROPERLY IDENTIFY MALFUNCTIONS MAY RESULT IN SERIOUS INJURY OR DEATH.

WARNING

REGULARLY INSPECT THE SKA-PAK AT RESPIRATOR INCLUDING THE ELECTRONIC ALARM AS DESCRIBED IN THIS INSTRUCTION. VERIFY THAT THE PROPER BATTERIE S AR E US E D AND THAT TH ERE IS NO DAMAGE TO OR MODIFICATION OF THE UNIT THAT WOULD IMPAIR T HE INTRINSIC SAFETY. IF THE SKA-PAK AT IS USED IN AN EXPLOSIVE OR FLAMMABLE ATMOSPHERE, FAILURE TO CORRECT CONDITIONS THAT MAY IMPAIR THE INTRINSIC SAFETY OF THE EQUIPMENT MAY LEAD TO A FIRE OR AN EXPLOSION WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.

WARNING

THIS INSPECTION PROCEDURE REQUIRES USING A SMALL AMOUNT OF AIR FROM THE SELF-CONTAINED AIR SUPPLY CYLINDER ON EACH INSPECT ION. IF THE CYLIN DER GAUGE IS NO LONGER READING "FULL", THE CYLINDER MUS T BE RECHARGED TO ITS FULL CONDITI ON BEFORE RETURNING TO SERVICE. USE OF A CYLINDER AIR SUPPLY THAT IS LESS THAN FULL MAY RESULT IN REDUCED DURATION OF THE RESPIRATOR AND MAY RESULT IN SUDDEN TERMINATION OF BREATHING AIR WHICH COULD CAUSE SERIOUS INJURY OR DEATH.

WARNING

DAMAGED CYLINDERS MAY SUDDENLY LEAK OR RUPTURE IF LEFT CHARGED WITH COMPRESSED AIR. FAILURE TO INSPECT FOR DA M A G E AND TO E M P T Y T H E AI R FRO M DAMAGED CYLINDE RS MAY RESULT IN SERIOUS INJURY OR DEATH.

OPERATIONAL TESTING OF THE RESPIRATOR

1. Don the facepiece properly (see donning procedures under USE OF THE RESPIRATOR) or hold the facepiece tightly to the face to effect a good seal. Inhale slightly and hold breath. A negative pressure (suction) shall be created, pulling the facepiece toward the face. Hold breath for 5 to 10 seconds. If leakage is noted, remove the respirator from service and tag for repair by authorized personnel.

2. Briefly remove the facepiece (see doffing procedures under TERMINATION OF USE) to take a breath if necessary. Don the facepiece or hold the facepiece tightly to the face. Depress the air-saver/ donning switch fully and release. Open the cylinder valve by turning the valve knob counterclockwise fully. The VIBRALERT will actuate and the ELECTRONIC alarm will flash for approximately five seconds to initialize. No air flow shall be detected at this time. Inhale sharply to start the flow of air, then take one breath and hold.

NOTE

IF THE PURGE VALVE IS ADJUSTED TO PRODUCE A FLOW, IT MAY NOT BE POS S IBLE TO RESET THE A IR-SAVER / DONNING SWITCH BY INHALING; CLOSE THE PURGE VALVE AND REPEAT THE TEST. Air shall flow freely into the facepiece during inhalation and stop

when inhalation ceases. VIBRALERT shall actuate. Hold breath for 5 to 10 seconds. If airflow continues after inhalation has ceased, recheck the fit of the facepiece (see Step 1). If airflow continues after checking the fit, remove the respirator from service and tag for repair by authorized personnel. Exhale into the facepiece and take a second breath. Air shall leave the facepiece through the exhalation valve during exhalation and fresh air shall flow into the facepiece on inhalation. Depress the air saver switch fully and release. Doff the facepiece. No air shall flow from the facepiece.

Verify that the air supply cylinder gauge is reading "FULL." If gauge

is reading less than "FULL" replace air supply cylinder with one that is "FULL."

PREPARATION FOR USE

Th e purp ose fo r the self-c o ntained air s upply on the SKA-P A K AT respirator is to provide breathable air during escape from objectionab le, oxyge n deficien t and/or unbreathab le (toxic ) atmosphe res. If respirator use is expected at temperatures near or below freezing or if the respirator is to be stored in temperatures near or below freezing, refer to LOW TEMPERATURE OPERATION section for additional information and supplemental procedures. Before initiating any activity which requires use of the SKA-PAK AT respirator, both the normal exit route and one or more emergency escape routes to an area with a safe, breathable atmosphere shall be determined. During normal exit, the respirator will be supplied with air through the air supply hose from the air supply system. Emergency exit routes shall be such that they can be travelled using the selfcontained air supply. If escape cannot be safely accomplished within the limited time of respiratory protection provided by this respirator after the air supply hose is disconnected, DO NOT USE THIS RESPIRATOR; make whatever changes are required for safety, such as selecting a respirator of appropriate self-contained duration. Determine the amount of air supply hose required for the job and ensure that it is less than or equal to the maximum allowable length of that type of hose. See Table 1. Be certain that the air supply system is providing safe, respirable breathing air and is compatible with the air supply hose. Be certain that personnel who are knowledgeable in the operation of the air supply system are present to monitor and maintain the supply pressure at the point of attachment of the air supply hose(s) to the air supply system(s). Verify that the air supply cylinder gauge is reading "FULL." If gauge is reading less than "FULL" replace air supply cylinder with one that is "FULL."

BEGIN USE OF THE RESPIRATOR

1. Replace head protection if required.

2. If regulator is not installed, depress donning switch and verify free flow of air has stopped. Verify the gasket is in place around the outlet port of the regulator and not damaged. With the red purge valve in the 12 o'clock position, align the two flats of the outlet port with corresponding flats in the facepiece port and insert. Rotate the regulator counterclockwise (viewed from inside of facepiece) so that the red purge valve knob is situated on the left side of the facepiece. The lock tab on the mask-mounted regulator will lock into the facepiece retainer with a "click". If properly engaged the regulator will not rotate. Inhale sharply to start the flow of air. Take several deep breaths to check the operation of the respirator; breathing should be free and unrestricted as described under PREPARATION FOR USE.

3. FULLY OPEN THE CYLINDER VALVE by turning the valve knob to the full counterclockwise position. This will require approximately 2 1/2 complete rotations of the cylinder valve knob. The ELECTRONIC alarm shall flash both lights for approximately five seconds to initialize and stop. The cylinder pressure gauge on the ELECTRONIC alarm shall read "FULL". The VIBRALERT shall NOT actuate and breathing shall continue normally. See USE OF THE AUTOMATIC TRANSFER FEATURE section of this instruction.

NOTE

IF THE YELLOW BATTERY LIGHT CONTINUES TO FLASH AFTER INITIALIZATION, REPLACE THE BATTERY BEFORE USE OF THE RESPIRATOR. SEE THE ELECTRONIC ALARM BATTERY REPLACEMENT SECTION OF THIS INSTRUCTION. Check the air pressure at the point of attachment of the air supply system to the supply hose during inhalation and exhalation; the air pressure shall meet the operating pressure requirements for the respirator at all times. The airline connection hoses must be protected from moisture during use by keeping them connected to an air supply hose or, on dual plug versions, by capping the unused plug with the cap provided. If it is possible that water has entered the airline connection hose, remove the airline connection hose from the pressure reducer and purge the hose with clean, dry breathing air until the hose is dry. Care should be taken to avoid prolonged contact with or submergence of the air supply hose in liquid solvents and/or petroleum products during use. Absorption of solvents into the rubber supply hose over time may result in contamination of the air flowing through the hose.

TERMINATION OF USE

Exit from the area requiring respiratory protection is normally made by retracing the path used during entry so that exit can be made while air is supplied by the air supply system through the air supply hose. After leaving the contaminated area and arriving in a safe, breathable atmosphere, doff the facepiece (i.e. remove the facepiece and terminate respiratory protection) as follows:

1. Be certain that respiratory protection is no longer required.

2. Loosen the head harness s traps by simultan eously lifting t he

buckle release levers outward (away from the head) and pulling them away from face. The buckle release levers are U- shaped extensions of the facepiece buckle assemblies.

3. Depress the air-saver/donning switch fully and remove the face-

piece by pulling it up and over the head. If the facepiece is removed before depressing the air-saver/donning switch or before disconnecting the air supply hose from the airline connection hose, there will be a constant flow of air from the facepiece. The user must be aware that while the respirator free-flows the air supply source pressure may drop significantly.

Close the air supply cylinder valve by pushing in on the cylinder

valve knob while turning clockwise.

Disconnect the air supply hose from the airline connection hose

and turn off the air supply system if not being used by others.

4. To resume use of the respirator, replace the air supply cylinder

with a "FULL" cylinder and repeat the procedures in the PREPARATION FOR USE and USE OF THE RESPIRATOR sections above as applicable.

5. To terminate use, remove the respirator from service and tag for

inspection and cleaning.

DO NOT DROP OR DRAG THE FACEP IE CE

WARNING

FAILURE OF THE RESPIRATOR TO SUPPLY AIR DURING ESCAPE

If air flow to the facepiece is interrupted while using the emergency air supply from the cylinder:

1. Be certain that the facepiece fits the face tightly during inhala-

tion.

2. Check the cylinder air gauge and be certain the cylinder contains

air (gauge indicates above empty).

3. Be certain that the cylinder valve is fully open.

EMERGENCY USE PROCEDURE

IF CONDITIONS IN THE WORKPLACE REQUIRE EMERGENCY EVACUATION during respirator use, the preferred proce dure is to egress with respirator connected to the air supply hose following the path taken during entry into the workplace. If it becomes necessary to disconnect the respirator from the air supply hose for egress—for instance, if the hose is entangled or if it is necessary to exit by a different route—the user shall disconnect the hose and immediately leave the area requiring respiratory protection. The VIBRALERT end of service time indicator alarm shall actuate indicating that the respirator user is now breathing from the air supply cylinder. The ELECTRONIC alarm RED light shall actuate when the air supply in the cylinder has dropped below 90% (+/-5%) of "FULL". IF EITHER THE VIBRALERT END OF SERVICE TIME INDICATOR OR THE ELECTRONIC ALARM ACTUATES AT ANY TIME DURING RESPIRATOR USE, leave the area requiring respiratory protection immediately. Actuation of the VIBRALERT means that the air supply has been interrupted and is no longer providing the necessary pressure to operate the respirator. Actuation of the ELECTRONIC a la r m RE D lig ht mean s th a t th e ai r su pp l y cy li n der has bee n de p le t ed to 90% (+/- 5 % ) of full v o lume. A c t u ation o f t h e ELECT R O N IC alar m LOW BATTERY YELLOW light means the battery must be changed. In any case, the user must leave the hazardous area immediately.

NOTE

THE SKA-PAK AT COMBINATION SCBA AND TYPE C RESPIRATOR IS A PRESSURE DEMAND OPEN CIRCUIT TYPE BREATHING APPARATUS. DURING USE, AIR SHALL FLOW FREELY INTO THE FACEPIECE DURING INHALATION ONLY, AND AIR SHALL CEASE FLOWING AT ALL OTHER TIMES. IF AIR CONTINUES TO FLOW FROM THE BREATHING REGULATOR AFTER INHALATION CEASES, THE PURGE VALVE (RED KNOB ON REGULATOR) MAY BE OPEN OR THE FACEPIECE MAY NOT BE SEALING AGAINST THE FACE. IF EXCESS AIR FLOW IS NOTICED DURING ESCAPE, CHECK THAT THE PURGE VALVE IS CLOSED (ROTATED FULL CLOCKWISE WITH POINTER ON KNOB UPWARD) AND THAT THE FACEPIECE HAS BEEN DONNED PROPERLY AND TIGHTENED PROPERLY WHILE CONTINUING YOUR ESCAPE.

1. BREATHE normally. When breathing from the air supply cylinder, the VIBRALERT end of service time indicator shall continue to actuate.

2. DISCONNECT the air supply hose from the airline connecti on hose, if necessary.

3. EGRESS to an area with a safe, breathable atmosphere following all precautions and procedures of your respiratory protection program.

4. When in a safe breathing atmosphere, doff the facepiece according to the instructions under TERMINATION OF USE.

5. Close the cylinder valve by pushing in and rotating the cylinder valve knob full clockwise.

6. Remove the respirator from service and tag for charging, inspection and cleaning.
