C-4 Protective Mask
Appearance

The C-4 Protective Mask is the current issued gas mask to the Canadian Forces. The C4 is a negative-pressure, full-face respirator with an ergonomic butyl rubber face piece designed for challenging operations and activities. With its stretch-fabric mesh head harness and two simple adjustment pull straps, the C4 respirator is easily donned and doffed. The Canadian Forces C-4 Protective Mask will be replaced by the AVON FM53 sometime in the 2020 year. [1]
Airboss Low Burden Mask
In 2019, it was replaced by the AirBoss Defence Low Burden CBRN Mask.[2] The mask is similar in appearance to the M50 joint service general purpose mask, which is currently used by the US military, but is not identical.
