What hazard is commonly associated with Class 4 lasers?

Class 4 lasers are high-powered lasers that pose several serious hazards due to their intensity and energy output, with fires being a common concern. When a Class 4 laser strikes combustible materials, it can ignite them, leading to potential fires. These lasers can also create sparks or hot surfaces that can act as ignition sources, further increasing the fire risk.

In laboratory settings, areas where Class 4 lasers are used must be carefully managed to minimize combustible materials and implement proper fire safety protocols. This includes having fire extinguishing methods readily available and ensuring that staff are trained to recognize and mitigate fire hazards associated with these powerful lasers.

While the other hazards mentioned, such as electrical shock, chemical exposure, and mechanical injury, can certainly occur in environments that use lasers, they are not exclusive to Class 4 lasers and are generally less prominent in discussions about the specific risks posed by these high-powered devices.
