Pneumatic tools are powered by compressed air. Common air-powered hand tools include jack hammers, chipping hammers, wrenches, grinders, and nail guns. Some of these tools shoot or create projectiles which can cause bodily injury. Additionally, pneumatic tools produce ear-damaging noise and release atomized oil and water vapor into the air. This module describes pneumatic tools hazards and how to deal with them.
