Use this self-assessment tool from WorkSafeBC to better understand the risk that anhydrous ammonia (ammonia) in industrial refrigeration systems can present to the workplace. It will help you determine whether your facility has effective controls in place to protect workers from exposure to ammonia.

Common health hazards of anhydrous ammonia arise from its inhalation and corrosive effects. These effects can harm workers if there is an accidental release. In addition to the health hazard, at higher concentrations — for example, during a significant release in an enclosed area — and with ineffective controls, a fire or explosion may occur.
