DESCRIPTION

The air masks from MSA are pressure-demand, selfcontained breathing apparatus (air mask) certified by the National Institute for Occupational Safety and Health (NIOSH) for use in atmospheres immediately dangerous to life or health:

``Immediately dangerous to life or health’’ means conditions that pose an immediate threat to life or health or conditions that pose an immediate threat of severe exposure to contaminants, such as radioactive materials, which are likely to have adverse cumulative or delayed effects on health’’ [Title 42 CFR, Part 84.2, (Q)]

• This air mask is not compliant with National Fire

Protection Association (NFPA) Standard 1981. The air mask should not be used for firefighting applications where NFPA compliance is required.

• This air mask is not NIOSH approved for use

against CBRN live agents. If NIOSH CBRN Agent Approval is required, use a NIOSH CBRN Agent approved FireHawk

Air Mask.

• This air mask must be equipped with an Ultra Elite

Hycar Facepiece (model numbers 7-935-7. 7-935-8, and 7-935-9) and a CBRN regulator (model numbers 10060982 or 10060983) when exposure to CBRN live agents is possible. DO NOT use a silicone facepiece or a regulator that is not identified as CBRN regulator against CBRN live agents.

Failure to follow these warnings can result in serious personal injury or death.

The AirHawk II Air Mask consists of the following major sub-assemblies.

• first stage regulator

• second stage regulator

• air cylinder and valve

• Audi-Larm™ Audible Alarm

• carrier and harness

• facepiece

FIRST STAGE REGULATOR

The first stage regulator is a pressure reducer that keeps the pressure to the mask mounted regulator at approximately 80 to 100 psig throughout the entire operating pressure range of the cylinder. The regulator has a redundancy feature to minimize the possibility of a first stage failure. The regulator uses a large sintered filter which is easy to replace. The filter captures particulates that may be in the air stream.

SECOND STAGE REGULATOR

This is a pressure-demand regulator, which keeps a positive pressure in the facepiece all the time. The release button on top of the regulator stops air flow. To stop airflow, push the button in. To restart the regulator, inhale sharply. The regulator attaches to the facepiece with a Push-To-Connect connector or slide connector. The regulator delivers large flow rates accurately and quickly.

AirHawk II Air Mask with the FireHawk numbers 10060982 and 10060983) are considered by MSA to be “CBRN hardened.” They can be identified by Firehawk Regulator model number and the CBRN marking on the underside of the regulator housing. Air mask with these regulator models have passed CBRN live agent testing, but are not CBRN-approved by NIOSH since they are not certified as NFPA compliant.

The air cylinder and valve consists of a tank and a cylinder valve assembly. The cylinder valve includes a valve body, cylinder valve inlet tube, handwheel, safety disc (burst disc), and pressure gauge. The pressure gauge shows the air pressure in the cylinder continuously. The gauge is calibrated in 100 psig increments. For example, a gauge reading of 20 is read as 20 x 100 or 2,000 psig. A handwheel is used to open and close the cylinder valve.

AUDI-LARM AUDIBLE ALARM

The audible alarm sounds when there is approximately 25% of the air mask’s rated service time remaining. The alarm also sounds when the cylinder valve is first opened, providing an audible indication that the alarm is functioning.

CARRIER AND HARNESS

The carrier consists of a backplate, a cylinder strap with buckle to hold the cylinder, and a harness, consisting of shoulder straps, chest strap (optional), adjustable pullstraps waist-strap, shoulder pads (optional) and belt mounted regulator retainer.

LUMBAR PAD (OPTIONAL)

The lumbar pad with a flared design is designed to provide a cushion between the wearer and harness. The flared design evenly distributes cylinder weight across the wearer’s hips.

RESCUE BELT (OPTIONAL)

The MSA Fire Service Rescue Belt is a personal escape system integrated into the carrier and harness assembly. The system is designed to provide the user with a means of escape from an elevated position. Care and use instructions are provided in User Instructions P/N 10052748 (P/N 10115063 for Rescue Belt II).

FACEPIECE

Two facepieces are available in three sizes.

• The Ultra Elite Facepiece

• The Advantage

Only Ultra Elite Hycar Facepieces (model numbers 7-9357, 7-935-8, and 7-935-9) have been tested against and meet CBRN live agent test requirements. Silicone

facepieces are NOT CBRN-approved.

The facepieces have a low-resistance, pressure-demand exhalation valve designed for easy cleaning. An inhalation check valve in the inlet housing keeps moisture and contaminants out of the mask mounted regulator. The Ultra Elite Facepiece has a speaking diaphragm for clear, short-range communication.

DONNING

actoolsupply.com

DONNING THE AIR MASK

1. Remove the facepiece from the case.

Do not use a cover lens in a high-temperature environment. High temperatures may distort the cover lens, or moisture trapped between a cover lens and the facepiece lens may condense and distort vision. Always remove the cover lens before donning the facepiece.

2. Check that the red bypass knob is fully closed (clockwise).

2. Ensure that the AudiLarm coupling nut is hand-tight (no tools).

3. Check that the cylinder is fully pressurized.

If the cylinder is not full, the service time is reduced accordingly & should not be used.

DO NOT use an air mask with a loose Audi-Larm coupling nut. Using an air mask with a loose coupling nut can cause o-ring failure which can result in sudden loss of cylinder pressure. Always hand-tighten the coupling nut before using the air mask. Failure to follow this warning can result in serious personal injury or death.

4. Reach inside the right shoulder straps and grasp the pressure gauge, slide left arm through left shoulder straps.

5. Bend forward slightly, rest it on your back.

6. Attach the chest strap (optional).

7. Fasten the waist-strap and pull it tight for a snug fit.

8. As you straighten up, pull the shoulder strap tabs out. Hike the unit up for a comfortable fit.

9. The shoulder straps and waist-strap ends must be tucked in and lay flat across the body.

3. Reach behind and open the cylinder valve fully. Listen for the alarm to sound briefly.

4. As the pressure rises from 50 to 200 psig, the alarm sounds automatically, indicating that the alarm is functional.

If the alarm fails to sound, do not use the apparatus. The air mask must be checked and corrected for proper operation by an MSA trained or certified repairperson before using. Failure to follow this warning may result in serious personal injury or death.

5. No air should flow from the regulator. If it does, repeat steps 1 and 2.

6. Check the gauge and cylinder gauges. Gauges must be within 220 psig for 2216 psig; 450 psig for 4500 psig.

4. Push headband pad towards neck, retighten the straps (if necessary) for best visibility and fit. Tuck in the ends of the straps so they lie flat across the head.

FACEPIECE FIT CHECK

Check the inhalation valve, inhale. If you do not receive sufficient flow of air, do not use facepiece. The facepiece must be repaired or replaced.

Do not wear eye glasses under the facepiece. The temples or sidebars on eye glasses will prevent an airtight seal. if you must wear glasses, install the spectacle kit. Failure to follow this warning can cause inhalation of contaminated air, resulting in serious respiratory injury or death.

When using the Advantage 4000 Facepiece, ensure the inhalation valve disc is laying flat against the adapter orifice.

1. Extend the facepiece straps fully. Place neckstrap around your neck and don the facepiece by inserting your chin first.

1. To check for facepiece fit, hold the palm of your hand over the inlet connection and inhale. Hold your breath at least 10 seconds. The facepiece should collapse and stay collapsed against your face. If it does not, readjust the facepiece and test again. If this

does not correct the leak, do not use the facepiece.

When replacing cylinder valves or after retesting of cylinders, make sure the proper cylinder valve, burst disc, and gasket are installed prior to cylinder recharging. Establish the service pressure of the cylinder. Type 3AA (steel) cylinders that bear a plus (+) sign after the latest retest date may be recharged to a pressure 10% greater than the stamped service pressure, i.e., a cylinder stamped 3AA2015 with a plus (+) sign after the latest test date may be recharged to 2216 psig (this applies to steel cylinders only). Steel cylinders without a plus (+) sign stamped after the latest test date must be removed from service. All other cylinders which are not type 3AA shall be filled to the designated service pressure only (as found on the DOT approval label or stamping). Appropriately connect the cylinder to the filling recharge system and refill. Terminate the filling when the pressure reaches service pressure and allow the cylinder to cool to room temperature.

If necessary, top-off the cylinder such that service pressure is attained with the cylinder at a temperature of 70°F. Close the valves on the cylinder and the recharge system and remove the cylinder. Apply a soap solution to determine if there is any leakage between the cylinder and the valve. If there is no leakage, the cylinder is now ready for re-use.

STORAGE

Do not store the apparatus or spare cylinders within or near an area where the apparatus can or might be exposed to any substances that will or might attach any part of the apparatus, causing the apparatus NOT to perform as designed and approved.

Do not store the apparatus with an empty or partly filled cylinder. Always install a fully-charged cylinder so that the apparatus is ready for use. Complete Inspection and Cleaning and Disinfecting Procedures are outlined in this manual. Ensure the complete apparatus is clean and dry. Ensure the facepiece head harness adjustment straps are fully extended. Place the complete apparatus in the storage case or suitable storage location so it can be easily reached for emergency use.

COLD WEATHER OPERATION

actoolsupply.com

SUGGESTED PROCEDURES FOR COLD WEATHER OPERATION

Moisture can cause problems in Air Masks if it freezes. However, moisture can cause freezing problems even if the surrounding air is above freezing. This is due to air flowing from the cylinder through the regulator drops from cylinder pressure to close to atmospheric pressure very quickly. As it does so it expands, causing the air and the regulator to become colder. Although the surrounding temperature may be warmer than 32°F, the temperature inside the regulator may be lower. Any water inside could turn to ice and restrict airflow.

1. To keep moisture from entering the mask-mounted regulator. Stow the regulator in the STAND-BY belt mount.

2. When the Air Mask is away from heat, water spray can freeze on the regulator surface. Ice can build up and freeze the buttons, bypass valve, and the release tabs. Before entering or re-entering a hazardous atmosphere, make sure the buttons, release tabs, and bypass valve are ice-free and operating properly. Periodically, check the bypass to be sure it is ice-free.

3. Moisture can enter through the cylinder valve or coupling nut when cylinders are replaced on the Air Mask. When replacing cylinders, be careful to prevent moisture or contamination from entering the system. Remove any ice from these fittings. Wipe the coupling nut threads and cylinder valve threads dry before disconnecting the cylinder. Water can contaminate the system and freeze.

4. NIOSH certification requires a nosecup at temperatures below 32°F. The nosecup reduces lens fogging and must be used whenever freezing conditions are encountered.

5. Thoroughly dry the facepiece and mask mounted regulator after cleaning and disinfecting. Follow Confidence Plus

CLEANING AND DISINFECTING

Depending on the cleaning policy adopted, either a designated person or the user should clean each device after each use. ANSI standards suggest that users should be trained in the cleaning procedure. Confidence Plus Cleaning Solution (P/N 10009971) from MSA is recommended. It cleans and disinfects in one operation. It retains its germicidal efficiency in hard water to inhibit the growth of bacteria. It will not deteriorate rubber, plastic, glass, or metal parts. Refer to label for user instructions.

• DO NOT use any cleaning substances that can or

might attack any part of the apparatus.

• Alcohol should not be used as a germicide

because it may deteriorate rubber parts.

• If not rinsed thoroughly, cleaning agent residue

may irritate the wearer’s skin.

1. Preparing Solution a. Follow the instructions with the Confidence Plus

Cleaning Solution.

b.If the Confidence Plus Cleaning Solution is not

used, wash in a mild cleaning solution, rinse thoroughly, and submerge in a germicide solution for the manufacturer’s recommended time.

2. Clean and Disinfect the Facepiece a. Remove the mask mounted regulator from the

facepiece.

b.Thoroughly wash the facepiece (and nosecup) in the

cleaning solution. A soft brush or sponge can be used to clean the soiled facepiece.

c. Rinse the facepiece and components in clean,

warm (110°F), water (preferably running and drained).

d.Clean the pressure demand exhalation valve by

pressing in on the stem with a blunt object and flushing with clean water.

e. Allow the facepiece to air dry. Do not dry the parts

by placing them near a heater or in direct sunlight. The rubber will deteriorate.

f. Operate the exhalation valve by hand to be sure it

works properly.

Note: Do not force-dry the parts by placing them in a heater or in direct sunlight. The rubber will deteriorate. When the facepiece is thoroughly dry, store the facepiece in the plastic bag that it was shipped in.

3. In general, only the facepiece requires cleaning and disinfecting after each use. If the apparatus is soiled (i.e. heavy smoke residue, or dirt accumulation) use a sponge damp with mild soap solution or use a soft/medium bristle brush to remove deposits that may interfere with normal operation of: a. Harness (straps and buckles) b.Cylinder carrier c. Cylinder (coupling nut, gauge, outlet connection) d.Audi-Larm audible alarm e. MMR remote gauge lens f. First stage regulator g. MMR second stage regulator. Cover outlet of the

MMR second stage regulator to prevent water, dirt or debris from entering.

4. Inspect the entire apparatus as you re-assemble it. Follow the Inspection Instructions.

5. Thoroughly dry the facepiece and regulator after cleaning and disinfecting. The facepiece can trap water which could enter the regulator.

INSPECTION

Inspect the entire air mask after it is cleaned and disinfected. ANSI Standards Z88.2 and Z88.5, describe three levels of inspection procedures which are to be performed. Refer to these documents, or to an inspection program prepared by a health professional in establishing an inspection program. Detailed repair procedures are located in the MMR User’s Maintenance Instructions.

If the air mask does not meet any of the following inspections, it must be removed from service. Do not inspect the air mask before cleaning if there is danger of contacting hazardous contaminants. Clean and disinfect first, then inspect. Failure to follow this warning can cause inhalation or skin absorption of the contaminant and result in serious personal injury or death.

COMPONENT INSPECTION (AFTER EACH USE AND MONTHLY)

1. Don the air mask following the instruction procedures. These steps make up the Air Mask Functional Test.

2. If all steps are performed successfully, remove the air mask and inspect it following the steps below.

3. Facepiece a. Inspect the facepiece for rubber deterioration, dirt,

cracks, tears, holes, or tackiness.

b.Check the harness headstraps for breaks, loss of

elasticity, missing buckles or straps. Check the straps for signs of wear.

c. Inspect the lens for cracks, scratches, and a tight

seal with the facepiece rubber.

d.The exhalation valve must be clean and operate

easily. The valve must move off the seat and return when released.

e. Inspect the facepiece coupling for damage. Also

check to be sure the spider gasket, and valve disc are present.

4. Cylinder and Remote Gauges a. Be sure you can see both gauge needles and face

clearly through the lens. Also be sure the gauge stem is not bent.

b.Inspect the gauge hose for any visible damage.

5. Audi-Larm Audible Alarm a. Check that the alarm is undamaged and clean. b.Ensure that the Audi-Larm Coupling nut is hand-

tight (no tools).

6. Quick-Fill and URC Coupling Inspection Inspect the URC and Quick-Fill coupling for tightness of the coupling halves and tightness of the coupling to the air mask. Perform both inspections simultaneously. a. Close the cylinder valve and relieve system

pressure. (See DISCONNECTING THE FIREHAWK

PUSH-TO-CONNECT REGULATOR or DISCONNECTING THE SLIDE-TO-CONNECT FIREHAWK REGULATOR for instructions).

b.Use a fine-tip ink

marker and a ruler or straight edge to draw a line on the male coupling. Make sure the line extends across the joint and coupling hex flats onto the Audi-Larm or Quick Fill manifold body.

c. Put the dust cover on the coupling. d.Grasp the dust cover by hand and, using maximum

effort, attempt to loosen the coupling at the joint by turning the dust cover counterclockwise. Do not

use tools.

e. If the line does not

line up across the joint...

...or across the joint

where the coupling attaches to the air mask, remove the air mask from service until a replacement coupling is installed. If the line does line up, the coupling is sufficiently tight and the air mask may be returned to service.

7. Cylinder Breathing apparatus cylinders should be recharged as soon as possible after use. Cylinders should not be stored partially charged for two reasons:

• If used without recharge, the service life of the

apparatus is reduced.

• The cylinder burst disc vents excess pressure if a

full cylinder is over exposed to fire or heat. If the cylinder is not full, it may be damaged before the burst disc vents.

It is also essential that the required inspections and tests be performed on all air mask cylinders in accordance with Department of Transportation (DOT) regulations. DOT regulations require that composite cylinders be retired from service after the fifteenth year. Please note this does

not include cylinder valve assembly which may be reused. Aluminum cylinder service life is indefinite if proper inspection and hydrotest procedures are followed and they indicate that the cylinder may remain in service. Please contact your MSA distributor or sales associate if you have questions or if you need additional information regarding this policy.

Note: ANSI Z88.5 recommends checking cylinder pressure weekly. For maximum safety the cylinders should be stored full or empty (pressure above ambient but less than 100 psig).

a. If the cylinder is less than FULL, recharge it before

storing it. Cylinder air must be at least CGA Quality Verification Level (Grade) D respirable air.

b.Inspect the cylinder valve for signs of damage. The

valve may be opened slightly to be sure it operates properly. Be sure to fully close the valve.

c. Inspect the cylinder body for cracks, dents,

weakened areas, to break or peel, or signs of heat-related damage. If the cylinder is damaged return it to an MSA Service Center.

d.Check the hydrostatic test date on the cylinder

approval sticker located on the cylinder neck. Fiberglass and Kevlar composite cylinders must be tested every three years. Steel cylinders and carbon fiber cylinders must be tested every five years.

causing the fibers

Aluminum cylinder life is indefinite if proper inspection and hydro test procedures are followed and they indicate that the cylinder may remain in service.

8. Harness a. Inspect all harness components for cuts, tears,

abrasion or signs of heat or chemically-related damage.

9. Carrier a. Inspect the cylinder strap and buckle to be sure it

holds the cylinder securely. Operate the latch to be sure that it opens and closes properly and that it holds the cylinder securely.

b.Inspect back plate for cracks, weakened areas or

signs of heat or chemically related damages.

10. Rescue Belt a. Detailed inspection instructions for the Rescue Belt

are provided under a separate manual, (P/N 10052748 (P/N 10115063 for the Rescue Belt II).

11. Record Keeping Following inspection, the date and initials of the designated person should be recorded on an inspection tag. A more detailed record of the operations performed can be noted on an inspection and maintenance log. Inspection tags and inspection and maintenance logs are available from MSA. When the inspection data has been recorded, the breathing apparatus is stored in a ready position.

FUNCTIONAL TESTS

actoolsupply.com

FUNCTIONAL CHECKS (AFTER EACH USE AND MONTHLY)

1. Check that the regulator works properly. The regulator outlet should be sanitized before and after testing. a. Check that the cylinder valve and buttons are

closed and that the system is not pressurized.

b.Gently inhale through the regulator outlet and hold

your breath for about 10 seconds. If the negative pressure is maintained, there is no leakage.

c. Gently exhale through the regulator outlet for about

10 seconds. If the positive pressure is maintained, there is no leakage.

d.Do not use the apparatus if airflow through the

regulator is detected in either test. Return the regulator to a certified repairperson.

2. Inspect the buttons and bypass valve. a. With the regulator pressurized, operate each valve

to be sure it operates. Venting of pressure relief valves (or a continuing flow of air through the regulator when the user is not inhaling) indicates that the regulator needs to be repaired.

b.Listen to the regulator. Any unusual sounds such as

whistling, chattering, clicking, or rattling mean that the regulator should be checked further.

c. If any of these symptoms occur, the apparatus must

be removed from service. Return the regulator to a certified repairperson.

3. Audi-Larm Audible Alarm a. Check the function of the audible warning device

by observing the regulator gauge pressure at which the alarms sounds. Perform this test with a minimum cylinder pressure of 1,200 psig for the Low Pressure Air Mask, and 2,000 psig for the High Pressure Air Mask.

b.Pressurize the system by opening the cylinder valve

for a moment, then close it. The alarm must sound

indicating it is functioning. c. Open bypass slowly. d.Watch the drop in pressure on the shoulder gauge

and the point at which the whistle must begin to

sound. Nominal gauge readings at which the alarm

starts to sound are listed below.

550 psig approximately (low pressure system) 1125 psig approximately (high pressure system)

e. The alarm must continue until the air pressure is

approximately 200 psig or less. If the whistle does

not function properly, the apparatus must be

removed from service.

Do not disconnect the regulator coupling nut when pressure is shown on the regulator gauge. Release all pressure from the regulator by opening the bypass valve. Removing the coupling nut with the regulator pressurized may result in serious personal injury, death, or damage to equipment.

f. Open the bypass valve slowly to release trapped air.

Close bypass valve. g. Unscrew the regulator coupling nut from the

cylinder valve. It is hand-tight and should not

require tools. h. Inspect the coupling nut for thread damage. Also be

sure there is an O-ring and that it is not damaged. i. Replace the O-ring if it is damaged.

FLOW TEST AND OVERHAUL REQUIREMENTS

actoolsupply.com

FLOW TEST AND OVERHAUL REQUIREMENTS

The air mask Regulator and alarm must be flow tested and overhauled at specific time intervals. These maintenance procedures must be performed by a trained repairperson or at a Certified Service Center. Contact your MSA sales representative. They will supply the information you need to meet these requirements.

The required replacement/overhaul schedule for selfcontained breathing apparatus from MSA is based on apparatus usage on an individual basis. The frequency required for air mask overhaul depends upon how often the apparatus is used. MSA breathing apparatus must be overhauled based on the actual level of usage, rather than on time alone.

Overhaul is covered in the Regulator Disassembly and Repair sections and includes installation of the Regulator overhaul kits.

MSA breathing apparatus must be flow tested every year using an MSA approved flow test device.

The following table summarizes MSA’s required frequency for overhaul and flow testing.

Average Recommended Recommended

Air Mask Usage* Overhaul Frequency Flow Test Frequency

1 cylinder per Every 3 years Every year day or greater

1 cylinder every Every 8 years Every year other day

1 cylinder per Every 15 years Every year week or less

*A decision to retire an air mask should be based on an air mask’s performance data and whether that data meets the specified level of performance as defined in maintenance requirements from MSA.

*The unit of air mask use is defined as the consumption of one 30 min. cylinder of air. Example: If three cylinders of air are used, the air mask would be considered to have been used three times. If an assessment of an air mask’s usage cannot be estimated or determined, then the air mask shall be overhauled every three years.
