GENERAL DESCRIPTION

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

TRAINING IS REQUIRED BEFORE USE. The SCOTT AIR-PAK SCBA 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 and is not to be used for purposes other than authorized by your respiratory protection program.

This respirator must not be used underwater.

The basic SCOTT AIR-PAK SCBA consists of a backframe and harness assembly, a cylinder and valve assembly to store a supply of breathing air under pressure, a dual path pressure reducer mounted on the back-frame, a facepiece mounted pressure demand breathing regulator, and a SCOTT full facepiece with a head harness to secure the facepiece to the face. All SCOTT AIR-PAK SCBA’s described in this instruction are equipped with at least two independent end of service time indicators, 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 and waist straps made of Kevlar®1.

Two backframe configurations are available: the Wireframe backframe and the AIR-PAK 75 Aluminum backframe. Both backframes are available as

2.2 (2216 psig), 3.0 (3000 psig), or 4.5 (4500 psig) models. All features apply to both backframes.

The full facepiece is available in several models and sizes and the head harnesses are available in a variety of materials including Kevlar. The facepiece must be properly fitted to the user before use. The facepiece may be readily detached 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 1910.134 Appendix A or ANSI Standard Z88.10 requires testing in the negative pressure mode using equipment such as a Portacount® 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. Refer to the FACEPIECE FITTING AND FIT TESTING section of this instruction.

WARNING

THE RESPIRATOR USER MUST IMMEDIATELY

LEAVE THE AREA REQUIRING RESPIRATORY

PROTECTION WHEN AN END OF SERVICE

INDICATOR ALARM ACTUATES. ACTUA-

TION OF ANY END OF SERVICE INDICATOR

ALARM WARNS THAT APPROXIMATELY 25%

OF FULL PRESSURE REMAINS IN THE AIR

SUPPLY CYLINDER (THAT IS, APPROXI-

MATELY 3/4 OF THE TOTAL AIR SUPPLY

HAS BEEN USED) OR THAT THERE IS A

MALFUNCTION IN THE RESPIRATOR. A DE-

LAY IN LEAVING THE AREA AFTER ALARM

ACTUATION MAY RESULT IN INJURY OR

DEATH.

The removable pressure-demand breathing regulator mounts directly to the facepiece and is equipped with an Air Saver/Donning Switch and a red Purge Knob.

All models of the AIR-PAK SCBA respirator are equipped with the VI- BRALERT® 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 nor-mal 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, if the primary air path of the pressure reducer becomes blocked or should fail closed, the sec-ondary 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.

The HEADS-UP DISPLAY is an independent end of service time indica-tor alarm attached to the facepiece mounted regulator and 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 batteries must be replaced. The HEADS-UP DISPLAY detects cylinder pressure directly and is totally independent of the VIBRALERT.

AIR-PAK respirators in compliance with NFPA 1981 (2007 edition) are fitted with a Rapid Intervention Crew/Company Universal Air Connection (RIC UAC) System which permits emergency replenishment of an approved SCBA breathing air supply cylinder from an approved air supply source while in use. This is not a Quick Charge attachment and must not be used for routine recharging of the cylinder, for “buddy breathing”, for transferring air from another SCBA cylinder, or any unapproved use. The RIC UAC is for emergency use only when the respirator user is incapacitated within the hazardous atmosphere.

Whenever any end of service indicator alarm or alarms actuate, the user must leave the area requiring respiratory protection immediately.

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 acces-sories that will be used with the respirator installed, such as a communications device installed on the facepiece.

PROCEDURE Attachment C, Sizing and Test Panels for LRPL for details.

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 PRES- SURE LEAK TEST. Refer to the DONNING PROCEDURE section of this instruction for the procedure. Follow the DONNING PROCEDURE CAREFULLY. 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.

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®1 Respirator Fit Tester. For Quantitative Fit Testing, SCOTT facepieces require use of the appropriate negative pressure testing equip-ment such as the Portacount Respirator Fit Tester along with the following:

P/N 052683**,

• SCOTT Probed Fit Test Adapter P/N 805628-01 or equivalent probed face-pieces and the full range of sizes and styles

installed on the facepiece

Depending on whether the user is fit testing for CBRN SCBA Open Circuit mode of operation (minimum Fit Factor equal to or greater than 500 minimum) or CBRN APR (minimum Fit Factor equal to or greater than 2000 minimum) appropriate negative pressure testing equipment must be used. For example, if you are Fit Testing for CBRN SCBA Open Circuit or CBRN APR, you should use a P100 Filter, SCOTT P/N 052683 and the SCOTT P/N 805628-01 Fit Test Adapter.

Page 5 of 52 P/N 595118-01 Rev. E 8/09

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.

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 stand-ing position during the test:

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, AV-2000 or AV-3000 SureSeal, must achieve a Fit Factor of at least 500 for CBRN SCBA (Open Circuit) use and a Fit Factor of at least 2000 for CBRN APR 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 for CBRN SCBA (Open Circuit) use and a Fit Factor of at least 2000 for CBRN APR use 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. If leakage is still detected, do not use the respirator.

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 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 PER-

FORMED, DO NOT USE THE RESPIRATOR OR ENTER THE HAZARDOUS

ATMOSPHERE.

The facepiece alone does not provide any protection against a hazardous atmo-sphere 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.

SERVICE LIFE

Each configuration of self-contained breathing apparatus (SCBA) certi-fied 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 either end of service indicator alarm actuates may be similarly reduced. The end of service indicator alarms actuate when approximately 25% of full cylinder pressure remains in the cylinder and valve assembly. Although all end of service indicator alarms are set to actuate at the set point of approximately 25% of full rated service pres-sure, they are completely independent of each other and therefore may not actuate at precisely the same moment. The alarms will continue to operate until the cylinder is nearly depleted.

The duration time of the respirator will depend on such factors as:

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 con-centrations greater than .04% normally found in atmospheric air;

7. the atmospheric pressure; for example, if used in a pressurized tun-nel 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;

WARNING

the respirator user must immediately leave the area requiring respiratory protection when an end of service indicator alarm actuates. Actua-tion of any end of service indicator alarm warns that approximately 25% of full pressure remains in the air supply cylinder (that is, approxi-mately 3/4 of the total air supply has been used) or that there is a malfunction in the respirator. A de-lay in leaving the area after alarm actuation may RESULT IN SERIOUS in-jury or death.

APPROVALS AND CERTIFICATIONS

All models of the SCOTT AIR-PAK SCBA described in these instructions conform to the requirements of Title 42 Part 84 of the Code of Federal Regulations and are certified by the National Institute of Occupational Safety and Health (NIOSH). Each respirator configuration is approved under the appropriate approval number for the air pressure and time duration. See the complete NIOSH approval label, SCOTT document P/N 89347-01, included with these instructions. Also see the CAUTIONS AND LIMITATIONS SECTION and the SPECIFIC LIMITATIONS section of these instructions for the cautions and limitations which apply to NIOSH certified respirators of this type.

The SCOTT AIR-PAK respirator is a modular design composed of replaceable subassemblies and may include certain SCOTT accessories.

Each major subassembly and accessory is labeled with its SCOTT part number. In order to maintain the NIOSH approved status of the respirator, use only those subassemblies and/or accessories listed as applicable to a particular NIOSH approval number.

All models of the SCOTT AIR-PAK SCBA are certified by NIOSH for use in ambient temperatures down to -25° F (-32° C). See LOW TEMPERATURE OPERATION section of this instruction. To maintain NIOSH certification, AIR-PAK SCBA cylinders must be refilled with compressed air which meets the requirements for Grade D or higher compressed air as specified in the Compressed Gas Association publication CGA G-7.1 entitled Commodity Specification for Air, available from the Compressed Gas Association, Inc., 1725 Jefferson Davis Hwy., Suite 1004, Arlington, VA 22202. In addition to meeting these requirements, the air must be dry to a dew point of -65° F (-54° C) or less. For fire service use, the preferred air quality shall be as specified in NFPA 1989. See SCOTT Specialist Level Maintenance Modules available upon request from SCOTT for additional information on refilling SCOTT SCBA cylinders.

The SCOTT AIR-PAK SCBA also meets the requirements of the National Fire Protection Association (NFPA) 1981 (2007 edition) Standard on Open- Circuit Self-Contained Breathing Apparatus for the Fire Service when configured in accordance with the NFPA approval. Due to the difference between the NIOSH approval requirements and the NFPA Standard 1981, not all subassemblies and/or accessories which are approved by NIOSH are certified under the NFPA standard. Included with this instruction is the NFPA Compliant Components Listing, SCOTT document P/N 595124-01, which lists the major subassemblies and/or accessories which may be used to configure a SCOTT respirator as compliant in accordance with the requirements of the NFPA Standard. When compliance with NFPA Standard 1981 is required, use only subassemblies and/or accessories that are listed on SCOTT document P/N 595124-01 as appropriate for use on a “certified model” SCOTT respirator. To maintain NFPA compliance, the SCOTT AIR-PAK SCBA must be used only in accordance with NFPA standard 1500, entitled Standard on Fire Department Occupational Safety and Health Program.

Specific combinations of respirator subassemblies may also qualify for Chemical, Biological, Radiological, and Nuclear (CBRN) Approval Status under the NIOSH standard. A complete list of the approved components is provided on the NIOSH CBRN Approval Label, SCOTT document P/N 89513-01. Before using a respirator for a CBRN application, the user must verify that the respirator is comprised of only CBRN approved components.

An approved mask mounted breathing regulator can be identified by its orange background label. An approved backframe assembly can be identified by a CBRN sticker. Other components must be identified by individual part number. Certain facepieces, such as those with silicone faceseals, are not approved for CBRN applications.

Regular Operational Inspection and Use of a CBRN equipped SCOTT AIR-PAK SCBA are essentially the same as for a standard SCOTT AIR- PAK SCBA. There may be differences defined by the user’s respiratory protection program or organization procedures for use in CBRN hazardous environments. It is the responsibility of the respirator user’s respiratory protection program to properly identify and maintain respirator equipment for CBRN applications.

• The attachment of components, accessories, or devices to the SCOTT AIR-PAK SCBA which are not listed on the complete NIOSH label may void the NIOSH approval and may degrade the performance of the respirator.

• The attachment of components, accessories or devices not listed on the NFPA listing, even if they are listed on the NIOSH approval label, may void the NFPA certification and may degrade respirator performance with respect to the NFPA certification requirements.

• The attachment of components, accessories or devices not listed on the CBRN Approval Label, even if they are listed on the NIOSH approval label or NFPA listing, may void the CBRN approval and may degrade respirator performance with respect to the CBRN approval requirements.

INTRINSIC SAFETY / SECURITE INTRINSEQUE

The SCOTT AIR-PAK SCBA respirator equipped with a Heads-Up Display P/N 200280-SERIES and/or a PASS distress alarm P/N 200451-SERIES is listed by SGS U.S. TESTING COMPANY INC. as intrinsically safe per ANSI/UL Std. UL-913 for use in Class I, Division 1, Groups C and D Hazardous Locations.

To maintain the Intrinsic Safety Listing, the respirator must be inspected regularly per the following Regular Operational Inspection procedures.

Do not tamper with or substitute components in any manner. Use only batteries of the type indicated in the Battery Replacement instructions.

Open the battery compartments only in an area known to be free of flammable or explosive hazards.

WARNING

FAILURE TO REGULARLY INSPECT THE

RESPIRATOR, INCLUDING ALL ELECTRON-

IC COMPONENTS, AS described in this instruction OR FAILURE TO CORRECT

DAMAGE TO THE ELECTRONIC COMPO-

NENTS, MAY IMPAIR THE INTRINSIC SAFETY

OF THE UNIT. THE INSTALLATION OF IN-

CORRECT BATTERIES OR SUBSTITUTION

OF ANY OTHER COMPONENTS MAY IMPAIR

THE INTRINSIC SAFETY OF THE UNIT. IF THE

RESPIRATOR IS USED IN AN EXPLOSIVE

OR FLAMMABLE ATMOSPHERE, IMPAIR-

ING THE INTRINSIC SAFETY OF THE UNIT

MAY LEAD TO A FIRE OR AN EXPLOSION

WHICH COULD RESULT IN SERIOUS INJURY

OR DEATH.

WARNING – Substitution of Components May Impair Intrinsic Safety. To reduce the risk of ignition of a flammable atmosphere, batteries must only be changed in an area known to be nonflammable. To reduce the risk of explosion, do not mix old batteries with unused batteries, or mix batteries from different manufacturers.

AVERTISSEMENT: La Substitution De composants Peut Compromettre La Sécu-rité Intrinséque; Afin De Prévenir L’Inflammation D’Atmospheres Dangereuses, NE Changer Les Batteries Que Dans Des Emplacements Désignés Non Dangereux.

Pour réduire le risque d’explosion, ne mélangez pas les vieilles batteries aux bat-teries inutilisées, ou mélangez les batteries de différents fabricants.

Page 10 of 52P/N 595118-01 Rev. E 8/09 the respirator user must immediately leave the area requiring respiratory protection when an end of service indicator alarm actuates. Actua-tion of any end of service indicator alarm warns that approximately 25% of full pressure remains in the air supply cylinder (that is, approxi-mately 3/4 of the total air supply has been used) or that there is a malfunction in the respirator. A de-lay in leaving the area after alarm actuation may RESULT IN SERIOUS in-jury or death.

HEADS-UP DISPLAY OPERATION

The HEADS-UP DISPLAY provides a visual monitor of the air supply in the cylinder and valve assembly. The display is fitted to the facepiece mounted regulator and appears across the bottom of the user's field of view through the facepiece. The HEADS-UP DISPLAY consists of four rectangular lights to represent the cylinder pressure at FULL, THREE-QUARTERS, ONE-HALF, and ONE-QUARTER. A fifth round red light indicates LOW BATTERY. The HEADS-UP DISPLAY operates as follows:

1. W hen respirator use begins, the HEADS-UP DISPLAY will initialize and illuminate all five lights for twenty (20) seconds. Operation of all five lights must be verified every time respirator use is begun and with every REGULAR OPERATIONAL INSPECTION. If the lights do not operate as described here, do not use the respirator. Remove the respirator from service and tag for repair by authorized personnel.

2. After initialization, the rectangular indicator lights will show the level of the air supply in the cylinder as follows:

a) FU LL cylinder is indicated by the two green lights glowing near the center of the display.

b) THREE-QUARTERS cylinder is indicated by a single green light glowing.

c) ONE-HALF cylinder is indicated by the yellow light flashing slowly at once a second.

d) ONE-QUARTER cylinder end of service time indicator is indicated by the red light at the far left flashing rapidly at ten times a second. When this warning light is flashing rapidly, the user must leave the hazardous atmosphere im-mediately.

3. The HEADS-UP DISPLAY has an automatic brightness control that dims the DISPLAY in low light situations and returns the DISPLAY to full brightness in bright light situations.

4. W hen the batteries require changing, the round LOW BATTERY in-dicator at the right of the display will light for twenty (20) seconds and then begin to flash slowly at once a second. When the LOW BATTERY indicator is actuated, the batteries still have sufficient life to operate the HEADS-UP DISPLAY longer than the longest dura-tion cylinder installed on the respirator. However, the batteries must be changed immediately upon termination of use of the respirator, or before reentry into a hazardous atmosphere. See the BATTERY REPLACEMENT section of this instruction.

REGULAR OPERATIONAL INSPECTION

The following procedure shall be used when you first receive the respira-tor 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 func-tion 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. NFPA recommends weekly inspection for emergency use respirators. 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 PAK ALERT SE 7 distress alarm PASS device, the following procedures must be modified to include inspection of the PASS device. Details of the REGULAR OPERATIONAL INSPEC- TION of the PASS device are included in the user instructions for the PAK ALERT SE 7 distress alarm. The part number of the required PAK ALERT SE 7 user instructions appears on the label on the 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 miss-ing, 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 (703- 412-0900).

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 SCBA’s must be visually inspected regularly and hydrostatically tested at the required intervals by a licensed cylinder retester. 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 Health and 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 ar-range for visual inspection and hydrostatic testing of cylinders by a licensed retester.

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