Powder-actuated technology was developed for commercial use during the Second World War, when high-velocity fastening systems were used to temporarily repair damage to ships. In the case of hull breaches, these tools fastened steel plates over damaged areas. [3] These tools were developed by Mine Safety Appliances, for the United States Navy. [4]
Another solution could be to use an extension pole for tools. [16] An extension pole is a fixed height pole attached to a powder-actuated tool, meaning the tool is out of the employee's hands, but they are still able to operate it. [16] Static posture.

A power tool is a tool that is actuated by an additional power source and mechanism other than the solely manual labor used with hand tools. The most common types of power tools use electric motors.

Pneumatic nail gun in use. A nail gun, nailgun or nailer is a form of hammer used to drive nails into wood or other materials. It is usually driven by compressed air (), electromagnetism, highly flammable gases such as butane or propane, or, for powder-actuated tools, a small explosive charge.
The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment. Examples of work assignments include "operating a grinder," "using a pressurized water extinguisher" or "changing a flat tire." Each of these tasks have different safety hazards that can be highlighted and fixed by using the job safety analysis.
