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.

The
skin is the tissue designed to regulate temperature,
secrete lubricants, and protect the body from <span>harmful
substances. It is one of the largest organs in the body and consists of two
layers --- the epidermis and the dermis. Its three main functions are to
protect, regulate, and sense.
It serves as the primary barrier of the body from impacts and pressure,
variations in temperature, radiation and chemicals, and micro-organisms. It
regulates body temperature through sweat and hair and is a reservoir for
Vitamin D synthesis. As a sensory organ it has a network of nerve cells that
detect and relay changes in the environment through heat, cold, touch, and
pain. </span>

Answer:
Muscular dystrophy runs in the mother's family.
Explanation:
Muscular dystrophy is able to pass down from the parents of a child. Females have two X genes that are able to make the dystrophin protein, but when one of their X genes becomes a carrier for muscular dystrophy, they can pass it down if that gene is the gene given to their child, which can become dangerous especially if the child is male. Males have an X and a Y gene, and depending on which gene is given to the child, the child will be either male or female. When the Y gene is given from the father and the defective X gene is given from the mother, the male child doesn't have another X gene to make the protein dystrophin and therefore is at risk for muscular dystrophy.
I'm not great at explaining things, I hope this helps :)
