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). A DELAY IN LEAVING THE
AREA AFTER ALARM ACTUATION MAY
RESULT IN INJURY OR DEATH.
WARNING
THE RESPIRATORY PROTECTION PROGRAM
UNDER WHICH THIS EQUIPMENT IS TO BE
USED MUST DETERMINE THE APPROPRIATE
L E V E L O F P R O T E C T I O N T H AT T H E
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.
CHOOSING THE APPROPRIATE EQUIPMENT
Respirators reduce but do not eliminate all exposure to the hazardous at-
mosphere. 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 respira-
tor is to be used must determine the appropriate level of protection that the
facepiece/respirator is expected to provide.
Use of inappropriate RESPIRA-
TOR 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 op-
eration 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 appro-
priate protective clothing for use with the ISCBA respirator and must insure
that protective clothing does not interfere with the operation of the ISCBA
respirator.
SERVICE LIFE
The 2216 ISCBA respirator is rated and approved by NIOSH as a 30 min-
ute duration unit and the 4500 ISCBA respirator is rated and approved by
NIOSH as a 30 minute / 45 minute / 60 minute duration unit (depending on
capacity of cylinder used) when properly donned, used and maintained by
trained personnel. A bell alarm actuates when approximately 25% of
the rated service time remains. The alarm will continue to operate
until the cylinder is nearly depleted.
The user should not expect to obtain exactly the rated service life 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 shorter, possibly as short as one-half the rated service
time. Likewise, the time remaining after the bell alarm actuates will be simi-
larly reduced.
The duration 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 excitement, fear
or other 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 concentra-
tions 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) 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 being used.
WARNING
THIS RESPIRATOR PROVIDES PROTECTION
ONLY TO THE USER’S RESPIRATORY
SYSTEM AND TO PART OF THE FACE.
I F T H E H A Z A R D O U S AT M O S P H E R E
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.
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 atmo-
sphere 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
C O N F I G U R AT I O N I N A H A Z A R D O U S
ATMOSPHERE MAY RESULT IN SERIOUS
INJURY OR DEATH.
