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.

E. We most often naturally awaken during NREM-3 sleep.
Explanation:
Sleep can be defined as a biological recurring state in which the mind and body of a living organism is characterized by altered (partial or total) consciousness, lessened sensory and muscular activities, as well as reduced physical interaction with the environment.
Generally, there are four (4) main pattern of sleep cycles and these includes;
I. Stage 1 sleep.
II. Stage 2 sleep.
III. Stage 3 sleep.
IV. Stage 4 sleep.
V. Rapid eye movement (REM) sleep.
Rapid eye movement (REM) sleep involves the movement of the eyes under the eye lids and this is the stage where dreaming occurs.
