Respirator Use Limitations
WARNING!
An approved professional must supply an applicable change-out schedule for air filtration
cartridges/canisters, unless the cartridge/canister has an end-of-service-life indicator. The change-
out schedule must include all factors that have an effect on respiratory protection, including work
practices and other conditions that are specific to the users' environment.
If this respirator is used for protection against substances that have poor warning properties, there
is no secondary method of notification about when to replace the air filtration cartridge/canister.
Obey additional precautions to prevent overexposure, such as a more conservative change-out
schedule or use of an SAR or SCBA.
Failure to obey these warnings can result in serious injury or death.
This is an approved PAPR ONLY when it is used in an approved configuration. For information about
approved configurations, refer to the G1 PAPR Approval Insert (PN 10192481).
NOTE:
The rubber neck strap (Model Number 7-2830-1) is not approved for use with the 4-point black
cloth head harness (Model Number 7-3104-1).
Do not exceed the maximum use concentrations set by regulatory standards.
Users must comply with the following MSA respirator use limitations. Do not exceed the following
maximum use concentrations during use:
• 1000 times the exposure limit for the contaminants in the environment if a quantitative fit test is
used. Using a qualitative fit test can decrease the maximum use concentration.
• Immediately dangerous to life or health (IDLH) concentration for any contaminant in the environ-
ment.
