What class of WHMIS does Compressed Gas fall under?

Compressed gas falls under Class A of the Workplace Hazardous Materials Information System (WHMIS). This classification is specifically designated for materials that are under pressure and can pose hazards due to their potential to expand rapidly upon release. Compressed gases can include a range of materials such as oxygen, propane, and helium, and they can create serious safety risks, including explosions, asphyxiation, or projectile hazards if the containers are damaged.

This classification is crucial for ensuring proper handling, storage, and emergency procedures are in place to protect workers who may encounter these materials. By understanding that compressed gases are in Class A, workers can better recognize the specific risks associated with these substances and take appropriate precautions to mitigate any potential dangers.
