Why should roofing employees refrain from using powder actuated tools on brittle materials?

Roofing employees should refrain from using powder actuated tools on brittle materials primarily because these tools can cause fragments to become dangerous projectiles. When a powder actuated tool is used, it fires a fastener using a small explosive charge. This action can lead to the shattering of brittle materials, resulting in fragments that can be propelled at high velocities. This poses a significant safety risk to workers in the vicinity, as these projectiles can cause serious injuries.

In situations where brittle materials are involved, the potential for creating hazardous conditions increases substantially. The explosive force could compromise material integrity, leading to unexpected breakage and flying debris. Understanding this risk is crucial for maintaining a safe work environment. Hence, it is essential to choose appropriate tools and methods specifically tailored to the properties of the materials being used.
