The powder-actuated tool must not be able to operate unless it is forced against the work surface with a force that is at least 5 pounds (2.2 kg) greater than the tool's entire weight.
<h3>Safety principles while using powder-actuated tools?</h3>
- Operate powder-actuated tools only in the presence of qualified, approved users who are familiar with the rules governing their usage (also known as explosive actuated fastening tools).
- Tools that use powder work like loaded weapons. Powder-activated instruments should be handled with the same care and safety measures as weapons.
- To operate and maintain the tool safely, refer to the manufacturer's instructions.
- Put on safety goggles, safety glasses, or a face shield together with a hard hat.
- Be sure to safeguard your ears.
- When working on ladders or scaffolds, you should always brace yourself to keep your balance.
- Keep equipment aimed in a secure direction. Never point a tool with a powder charge at someone.
- Just before using, load tools with powder action. Never remove loaded powder-actuated tools from a task.
