PA3NBC Canister
There is currently no NIOSH approved PAPR for the hospital preparedness application. NIOSH certification protocols have not been developed for the chemical warfare agents that may be manifest following such an incident The respirator assembly in this brochure, while it will provide this protection, is not NIOSH approved.
Bullard seeks to protect workers against the hazards they may encounter in a hospital decontamination setting. To that end, Bullard has combined its innovative and revolutionary new PAPR with the best cartridge available to provide a broad range of protection against the Toxic Industrial Chemicals and Chemical and Biological Warfare Agents that may be used in some type of terrorist attack.
The Bullard PA3NBC hospital preparedness canister is designed for and meets all NIOSH requirements for acid gases, formaldehyde, ammonia, and high efficiency particulate. It also provides protection against the chemical warfare agents and/or their surrogates as specified in the C2A1 Canister Military Specification as detailed below:

| *These tests are part of the performance specifications for the C2A1 military canister. The PA3NBC Canister meets or exceeds the performance requirements of the C2A1 canister for these gases. | ||||
WarningUse only the canister described in the above table. Used/particulate-laden canisters must be changed as a set and not individually. All canisters must be of the same type. Do not change canisters while in a hazardous atmosphere. Incorrect canister selection will invalidate all performance statements and approvals for this equipment.
Three (3) of the same type of canister must be used on the PA3BU blower unit.
The PA3NBC canisters and PA3H blower should only be used with the 20SICVH and 20SICV hoods. These hoods are made of Tychem® SL, which has been tested by DuPont and shown to be effective against chemical warfare agents. These hoods also feature a press polished vinyl lens adequate for hospital preparedness applications.
The respirator and canisters should not be used beyond eight (8) hours after initial exposure to chemical warfare agents to avoid the possibility of agent permeation. If liquid exposure is encountered, the respirator should not be used for more than two (2) hours.
Follow established canister change schedules to ensure that canisters are replaced before breakthrough occurs.
