Power Tool Hazards During Concrete Removal
By their very nature, power tools are potentially more hazardous in general than hand tools. Power sources such as compressed air, electricity, and gasoline further exacerbate the safety hazards brought about through careless handling or incorrect usage.
- Pneumatic power tools:
- The biggest safety concern with these is their air hoses, which can be either punctured or cut, or damaged by heat and chemicals. Any of these things can cause a hazard if the result is an uncontrolled whipping of the air hose. To avoid injury from free-flying hammer bits, make sure the bit is properly secured in the tool and avoid squeezing the trigger until the tool is in the work.
- Electric power tools:
- These must be properly grounded or double-insulated to prevent electrocution. Be sure to inspect the cord for fraying, cracks, and other damage before use, and avoid using an electric tool while standing on a wet surface.
- Gasoline power tools:
- One of the biggest hazards involved with these tools is the explosive nature of the fuel used to power them. Gasoline spilled on hot engine surfaces and the accumulation of vapors and fumes can cause explosive conditions. Refuel in a cooled engine where there is adequate ventilation, and away from sparks, flames and other heat sources.
