Final answer:
To prevent accidents, it is true to use nonslip mats, grab bars, and hand holds during bathing for safety. Electrical devices like hairdryers have safety warnings to avoid the risk of electrical shock by falling into water, which is highly conductive.
Step-by-step explanation:
It is true that to ensure safety during bathing, it is recommended to use nonslip mats, grab bars, and hand holds. These items help to prevent slips and falls by providing stability and traction in a wet and potentially slippery environment. Safety messages on electrical devices like hairdryers often warn against using them near a bathtub or basin full of water to prevent the risk of electrical shock. Water is an excellent conductor of electricity, and if an electrical appliance falls into water, it can electrify the water and potentially harm anyone in contact with it. This is a serious hazard that can lead to injury or even death, which is why such precautions are emphasized.
