What is a common risk when improperly handling compressed gases?

Improper handling of compressed gases poses a significant risk of explosion or fire due to leaks. When gases are under high pressure, a leak can release a large volume of gas quickly, creating an explosive atmosphere. If this gas is flammable or reactive, ignition sources in the environment can lead to catastrophic consequences, such as explosions or fires.

This risk is heightened in confined spaces where gas can accumulate, increasing the likelihood of ignition. Moreover, the high pressure of the compressed gas can exacerbate the situation, causing hazardous situations to escalate rapidly.

While other options do relate to the handling of gases, they do not encompass the immediate and dangerous risks associated with improper handling in the same way that the potential for explosions or fires does.
