SCOTT AIR-PAK 75i

Industrial Pressure-Demand

Self Contained Breathing Apparatus (SCBA)

Models

2.2 / 4.5

DESCRIPTION

The SCOTT AIR-PAK 75i self contained breathing apparatus (SCBA) is intended to provide respiratory protection to an individual when entering into, working in, and exiting from an objectionable, oxygen deficient, and/or unbreathable (toxic) atmosphere.

TRAINING IS REQUIRED BEFORE USE. The SCOTT AIR-PAK 75i SCBA 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. The SCBA must be used and maintained properly. 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.

At a minimum, the SCOTT AIR-PAK 75i SCBA consists of the following:

– a cylinder and valve assembly to store a supply of breathing air

under pressure,

– a backframe and harness assembly to support the cylinder and valve

assembly and pressure reducer on the body,

– a backframe mounted pressure reducer with a remote pressure

gauge,

– a facepiece mounted pressure demand breathing regulator with an

air saver switch,

– a SCOTT full facepiece and a head harness to secure the facepiece

to the face.

All SCOTT AIR-PAK 75i SCBA’s described in this instruction are equipped with one end of service time indicator, a remote pressure gauge mounted on the shoulder strap, and an air saver switch located on the breathing regulator. All model respirators described by these instructions are equipped with shoulder straps, waist straps and head harnesses are made of Kevlar1.

The full facepiece is available in a variety of models and sizes and must be properly fitted to the user before use. The facepiece design incorporates a nose cup, two inhalation valves and dual voicemitter assemblies. The facepiece detaches from the breathing regulator to allow for use of the best fitting and most comfortable size facepiece for each user. Fit testing per OSHA Standard 29 CFR Part 1910 or ANSI Standard Z88.2 requires testing in the negative pressure mode using equipment such as a Portacount Plus2 Respirator Fit Tester. For this, SCOTT facepieces require use of SCOTT Fit Test Adapter P/N 804057-01 or equivalent and appropriate negative pressure testing equipment. Mask Seal Kit P/N 805655-01 may also be required to attain a proper fit.

The removable pressure-demand breathing regulator mounts directly to the facepiece. The air saver/donning switch on the breathing regulator prevents the rapid loss of the air supply if the cylinder valve is open and if the facepiece is removed from the face or the regulator is removed from the facepiece. The red purge knob on the regulator allows air to flow into the facepiece in an emergency as well as to release residual air from the respirator after the cylinder valve is turned off.

All models of the AIR-PAK 75i SCBA respirator are equipped with the VIBRALERT alarm in the facepiece mounted regulator. The VIBRALERT alarm serves two functions: as an end of service time indicator, and to alert the user of a malfunction in the dual path pressure reducer. In normal operation, the VIBRALERT alarm vibrates the breathing regulator and facepiece to warn the user by both sound and feel that approximately 25% of full cylinder pressure remains. In addition, the VIBRALERT alarm will be activated to warn the user if there is a malfunction in the primary path of the dual path pressure reducer. Air is normally supplied through the primary air path of the pressure reducer. If the primary air path of the pressure reducer becomes blocked or should fail closed, the secondary air path will automatically begin supplying air to the breathing regulator and the VIBRALERT alarm will be actuated to warn the user of the malfunction.

An optional independent end of service time indicator alarm is the HEADS-UP DISPLAY attached to the facepiece mounted regulator. The HEADS-UP DISPLAY is standard on respirators required to have two independent redundant alarms. The HEADS-UP DISPLAY provides a visual monitor of the air supply with four lights that appear just below the facepiece field of vision. A separate low battery light warns the user that the battery must be changed. The HEADS-UP DISPLAY lights indicate the cylinder air supply is full to three-quarters with constant green lights, one-half cylinder with a slowly flashing yellow light, and warns the user that approximately one quarter or 25% of full cylinder pressure remains with a rapidly flashing red light. The HEADS-UP DISPLAY detects cylinder pressure directly and is totally independent of the VIBRALERT. See the HEADS-UP DISPLAY OPERATION section and the BATTERY REPLACEMENT section of this instruction for complete details.

THE RESPIRATOR USER MUST IMMEDIATELY

WARNING

LEAVE THE AREA REQUIRING RESPIRATORY PROTECTION WHEN THE END OF SERVICE INDICATOR ALARM ACTUATES. ACTUATION OF ANY END OF SERVICE INDICATOR ALARM WARNS THAT APPROXIMATELY 25% OF FULL PRESSURE REMAINS IN THE AIR SUPPLY CYLINDER (THAT IS, APPROXIMATELY 3/4 OF THE TOTAL AIR SUPPLY HAS BEEN USED) OR THAT THERE IS A MALFUNCTION IN THE RESPIRATOR. A DELAY IN LEAVING THE AREA AFTER ALARM ACTUATION MAY RESULT IN INJURY OR DEATH.

EXPORT AND IMPORT

The international transport of this equipment and portions thereof is regulated under United States export regulations and may be regulated by the import regulations of other countries.

P/N 595236-01 Rev. B 10/11

CHOOSING THE APPROPRIATE EQUIPMENT

Respirators reduce but do not eliminate all exposure to the hazardous atmosphere. Some facepiece/respirator combinations are more effective than others at reducing exposure depending on the nature and the concentration of the contaminant in the hazardous atmosphere. When choosing a respirator and facepiece, the respiratory protection program under which this respirator is to be used must determine the appropriate level of protection that the facepiece/respirator is expected to provide.

Use of inappropriate RESPIRATOR equipment for the work environment may result in exposure to the hazardous atmosphere which may cause serious injury or death.

The respiratory protection program must also take into consideration the levels of exposure which may be hazardous irrespective of respiratory protection (e.g.: contaminants which are toxic through exposure to unprotected skin). Additional protective equipment such as apparel may be required. However, any additional protective equipment must not interfere with access to or operation of the respirator. When properly donned and operated, the SCOTT ISCBA respirator provides limited protection from airborne contaminants to only the respiratory system and part of the face of the user. The using agency must provide the appropriate protective clothing for use with the ISCBA respirator and must insure that protective clothing does not interfere with the operation of the ISCBA respirator.

NIOSH approval is granted to respiratory protection equipment made up of specific combinations of parts or assemblies that have been successfully tested to the performance standards established by the approval agencies.

To maintain NIOSH approval, an AV-3000 facepiece equipped with a SureSeal face seal P/N 31001738 (Small), P/N 31001739 (Medium), or P/N 31001740 (Large) must be used only with Grey Nose Cup P/N 31001043 (Small), P/N 31001044 (Medium), or P/N 31001045 (Large).

If you are using an AV-3000 facepiece equipped with a SureSeal face seal and do not have a Grey Nose Cup, contact SCOTT or your authorized SCOTT distributor. Failure to comply with this requirement will void the approvals for your respirator. Use of a non-approved configuration in a hazardous atmosphere may result in serious injury or death.

WARNING

THE RESPIRATORY PROTECTION PROGRAM UNDER WHICH THIS EQUIPMENT IS TO BE USED MUST DETERMINE THE APPROPRIATE LEVEL OF PROTECTION THAT THE RESPIRATOR IS EXPECTED TO PROVIDE. USE OF INAPPROPRIATE RESPIRATOR EQUIPMENT FOR THE WORK ENVIRONMENT MAY RESULT IN EXPOSURE TO THE HAZARDOUS ATMOSPHERE WHICH MAY CAUSE SERIOUS INJURY OR DEATH.

WARNING

THIS RESPIRATOR PROVIDES PROTECTION ONLY TO THE USER’S RESPIRATORY SYSTEM AND TO PART OF THE FACE. IF THE HAZARDOUS ATMOSPHERE CONTAINS TOXINS OR CONTAMINANTS WHICH MAY POISON THROUGH THE SKIN, ADDITIONAL PROTECTIVE EQUIPMENT MAY BE REQUIRED. FAILURE TO PROVIDE ADEQUATE PROTECTIVE EQUIPMENT FOR THE HAZARDS IN THE WORKPLACE MAY RESULT IN SERIOUS INJURY OR DEATH.

WARNING

TO MAINTAIN NIOSH APPROVAL, AN AV-3000 FACEPIECE EQUIPPED WITH A SURESEAL FACE SEAL P/N 31001738 (SMALL), P/N 31001739 (MEDIUM), OR P/N 31001740 (LARGE) MUST BE USED ONLY WITH GREY NOSE CUP P/N 31001043 (SMALL), P/N 31001044 (MEDIUM), OR P/N 31001045 (LARGE). USE OF A NON-APPROVED CONFIGURATION IN A HAZARDOUS ATMOSPHERE MAY RESULT IN SERIOUS INJURY OR DEATH.

SERVICE LIFE

Each configuration of self-contained breathing apparatus (SCBA) certified by NIOSH is assigned a "service life" classification for a duration time of each size of air supply cylinder (30 minute, 45 minute, etc.). The service life duration time is determined by NIOSH using a breathing machine designed to simulate an average adult user performing work at a "moderate work rate."

Do not expect to obtain the NIOSH rated service life duration time from this respirator on each use. The work being performed may be more or less strenuous than that used in the NIOSH test. Where work is more strenuous, the duration may be less than one half the NIOSH rated service life, and the time remaining after the end of service indicator alarm actuates may be similarly reduced. The end of service indicator alarm actuates when approximately 25% of full cylinder pressure remains in the cylinder and valve assembly. The alarm will continue to operate until the cylinder is nearly depleted.

The duration time of the respirator will depend 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 emotional factors;

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

5. whether or not the cylinder is fully charged at the start of the work 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 psi gauge or approximately 30 psi absolute) 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. the condition of the respirator.

WARNING

THE USER OF THIS RESPIRATOR MUST RECEIVE TRAINING IN THE OPERATION OF THE RESPIRATOR INCLUDING THE OPERATION OF ALL OPTIONS AND/OR ACCESSORIES INCORPORATED IN THE RESPIRATOR. SEE WARNING AT THE BEGINNING OF PAGE TWO OF THIS INSTRUCTION.

WARNING

ONLY THOSE OPTIONS AND/OR ACCESSORIES AUTHORIZED BY SCOTT AND APPROVED BY NIOSH MAY BE INSTALLED IN THIS RESPIRATOR. THE USE OF UNAUTHORIZED AND/OR UNAPPROVED OPTIONS OR ACCESSORIES COULD CAUSE PARTIAL OR COMPLETE FAILURE OF THE RESPIRATOR WHICH MAY RESULT IN 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 Portacount1 Respirator Fit Tester. For 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.

THE USER MUST BE PROPERLY FITTED

WARNING

USING A RESPIRATOR QUANTITATIVE FIT TEST BEFORE USE AND FOLLOW ALL WARNINGS AND SPECIAL OR CRITICAL USER’S INSTRUCTIONS SPECIFIED DURING USE. FAILURE TO DO SO MAY RESULT IN SERIOUS INJURY OR DEATH.

WARNING

FIT TESTING IN ACCORDANCE WITH OSHA STANDARD 29 CFR PART 1910 IS REQUIRED AS PART OF THE REQUIRED TRAINING BEFORE USE OF THIS RESPIRATOR. FAILURE TO PROPERLY FIT AND TRAIN THE USER IN USE OF THE FACEPIECE AND RESPIRATOR MAY RESULT IN EXPOSURE TO THE HAZARDOUS ATMOSPHERE WHICH COULD LEAD TO SERIOUS INJURY OR DEATH.

WARNING

RESPIRATORS SHALL NOT BE WORN WHEN CONDITIONS PREVENT A GOOD FACE SEAL. SUCH CONDITIONS MAY INCLUDE, BUT ARE NOT LIMITED TO, GROWTH OF BEARDS, SIDEBURNS, FACIAL HAIR OR LOW HAIRLINE THAT CROSSES OR INTERFERES WITH THE SEALING SURFACE, THICK OR PROTRUDING HAIRSTYLES SUCH AS PONY TAILS OR BUNS THAT INTERFERE WITH THE SMOOTH AND CLOSE FIT OF THE HEAD HARNESS TO THE HEAD, A SKULL CAP THAT PROJECTS UNDER THE FACEPIECE, TEMPLE PIECES ON CORRECTIVE EYE GLASSES, EXCESSIVE USE OF COSMETICS INCLUDING MOISTURIZERS, MAKE-UP, OR AFTER SHAVE, OR ANYTHING ELSE WHICH INTERFERES WITH THE FACE TO FACEPIECE SEAL. ALSO, THE ABSENCE OF ONE OR BOTH DENTURES CAN SERIOUSLY AFFECT THE FIT OF A FACEPIECE. USE OF AN IMPROPERLY FITTED FACEPIECE MAY LEAD TO EXPOSURE TO THE HAZARDOUS ATMOSPHERE WHICH COULD RESULT IN SERIOUS INJURY OR DEATH.

P/N 595236-01 Rev. B 10/11

Page 8 of 44

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.

Periodically 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.

P/N 595236-01 Rev. B 10/11

REGULAR OPERATIONAL INSPECTION

The following procedure shall be used when you first receive the respirator and for daily or periodic inspection of the respirator. Respirators in regular use must be inspected at the start of each use period and during cleaning after each use. Respirators maintained for emergency use must be inspected as frequently as required to assure the respirator will function properly when required. The US Labor Department (OSHA), pursuant to 29 CFR 1910.134, requires at least monthly inspection of respirators maintained for emergency use. NIOSH recommends an inspection for cylinder pressure at least weekly. The condition of storage at your location or the regulations which apply to your respiratory protection program may require more frequent periodic inspections.

If the respirator is equipped with a PASS device distress alarm, the following procedures must be modified to include inspection of the PASS device. Details of the REGULAR OPERATIONAL INSPECTION of the PASS device are included in the user instructions for the PASS device. The part number of the required PASS user instructions appears on the label on the battery cover of the PASS device Sensor Module.

IF ANY DISCREPANCY OR MALFUNCTION IS NOTED DURING THE INSPECTION, DO NOT USE THE RESPIRATOR. REMOVE THE RESPIRATOR FROM SERVICE AND TAG IT FOR REPAIR BY AUTHORIZED PERSONNEL.

INSPECTION OF THE BREATHING AIR CYLINDER

1. Visually inspect breathing air cylinder and valve assembly for physical damage 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 distorted, and cylinders which show evidence of exposure to chemicals such as discoloration, cracks in the cylinder 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 emptied of compressed air. Publications on compressed gas cylinder inspection procedures are available from Compressed Gas Association Inc., 1725 Jefferson Davis Hwy., Suite 1004, Arlington, VA 22202 (703412-0900).

2. Check the latest cylinder hydrostatic test date to ensure it is current. The date of manufacture marked on the cylinder is also the date of the first hydrostatic test. All breathing air cylinders used with SCOTT AIR-PAK 75i SCBA’s must be visually inspected regularly and hy- drostatically tested at the required intervals by a licensed cylinder re-tester. Intervals for hydrostatic testing are established in the appropriate US Department of Transportation (DOT) specification or applicable DOT exemption, or in the appropriate Transport Canada (TC) Permit of Equivalent Level of Safety. Refer to the current revision of Safety Precautions for AIR-PAK Cylinders, SCOTT P/N 89080-01, available on request from SCOTT Safety. Composite fiber overwrapped cylinders must be tested up to their maximum life which, at the time of the publication of this instruction, is 15 years from the date of manufacture. It is the responsibility of your organized respiratory protection program to arrange for visual inspection and hydrostatic testing of cylinders by a licensed re-tester.

3. Check for damage of the cylinder valve hand wheel and the threads on the cylinder valve outlet.

4. Check the relief valve (burst disc) for damage or dirt.

5. Check the cylinder pressure gauge for “FULL” indication. If cylinder pressure is less than “FULL,” replace with a fully charged cylinder.
