Avon C50 Twin Port Gas Mask

Avon Protection's revolutionary FM53 multi-role Respiratory Protective Equipment (RPE) System has been developed specifically for specialist applications where the user needs to respond to ever-changing operational conditions. The FM53 is globally acclaimed as the most technically advanced mask and offers both positive pressure SCBA, PAPR, and negative pressure APR/capability. All these capabilities are available from one mask platform without the need to change components.

The FM53 system was developed to address the multiple threats encountered on the modern battlefield, war on terrorism, and peace-keeping operations. It provides protection against traditional chemical and biological warfare agents and select toxic industrial materials (TIMs).

Warnings and Limitation of Use

Always perform a satisfactory negative pressure leak test before using this respirator.
Do not use in confined spaces such as stills, tanks or sewers. This device does not provide supplied breathable air.
It is unlikely that the requirements for inward leakage of the system will be met if facial hair, or spectacle side arms pass under the face seal of the full face mask.
Do not use this equipment in Oxygen deficient atmospheres (<19.5% Oxygen) or for airborne contaminants or pollutants for which the approved filter canister(s) will not provide adequate protection.
Do not use this equipment in Oxygen enriched atmospheres (> 22.5% Oxygen).
System set-up, pre-check, donning, doffing, cleaning and maintenance must be performed in an area known to be free of contaminants.
Do not use if any system component demonstrates signs of wear or damage.
Do not use in areas where the head harness may be exposed directly to flame.
