Why are compressed gases classified as a controlled product under WHMIS?

Compressed gases are classified as a controlled product under WHMIS due to their potential hazards, particularly related to their ability to explode or release rapidly under certain conditions. The high-pressure nature of compressed gases means that if the container is damaged or improperly handled, they can burst, causing severe injuries or even fatalities. Additionally, when released suddenly, compressed gases can displace oxygen in the air, which poses serious health risks in enclosed or poorly ventilated spaces. This classification helps ensure that proper safety measures are in place for their storage, handling, and use, minimizing the risks associated with their inherent dangers.
