Explanation
All metal body portable electrical tools should be earthed to ensure safety. Earthing helps to prevent electric shocks by providing a path for the electrical current to flow into the ground in case of any fault or leakage. This protects the user from potential harm and reduces the risk of electrical accidents. Therefore, it is essential for the safety of the user that all metal body portable electrical tools are properly earthed.

Occupational health and safety regulations often require employers to provide a safe work environment and take measures to prevent noise-induced hearing loss among their employees.

Explanation
An electrical pressure mat is a safety device commonly used in industries. It is designed to detect pressure or weight and trigger a response or alarm system. These mats are typically placed in areas where there is a risk of accidents or unauthorized access, such as near machinery or restricted areas. When someone steps on the mat, it activates the system, alerting the operators or security personnel to take necessary action. Therefore, the statement that an electrical pressure mat is a safety device used in the industry is true.

Explanation
The correct way to lift heavy objects is to bend the knees, not the back, to avoid straining the back muscles. By bending the knees, the weight is distributed evenly and the thigh muscles are used to lift the object, which is safer and reduces the risk of injury. Therefore, the statement "The correct way to lift is bend the knees, bend the back, chain in, use thigh muscles" is false.
