The National Institute for Occupational Safety and Health (NIOSH) has issued a user notice for CBRN APR respirators with the use of suits qualified under the NFPA 1994 standard. The NFPA 1994-2007 certification of the Indutex JetGuard Plus Class 3 Ensemble specifies that the [email protected] CBRN APR is to be used as part of this ensemble.
This suit is designed with a pass-through hole and gasket on the visor that is interposed between the [email protected] mask and canister. Therefore, the fit of the respirator may be compromised when used as part of this Class 3 Ensemble.
NIOSH cautions that when a negative pressure APR is used with a Class 3 or 4 suit the face seal of the APR may be compromised, resulting in reduced respiratory protection.
