Final answer:
Heavy machinery, equipment, or parts that are suspended or held aloft need to be secured to prevent falling or shifting before employees can work under or between them.
Step-by-step explanation:
Heavy machinery, equipment, or parts which are suspended or held aloft by use of slings, hoists, or jacks must be secured to prevent falling or shifting before employees are permitted to work under or between them.
Securing heavy machinery or equipment is crucial to ensure the safety of employees. This can be done using various methods such as properly attaching slings or using locks or braces to prevent any accidental movement. By taking these precautions, the risk of accidents and injuries can be significantly reduced.
For example, when working with a crane, heavy loads are often lifted and moved above the work area. If these loads are not properly secured, they can fall and cause serious harm. By using slings or other lifting devices correctly and ensuring they are securely attached, the risk of accidents can be minimized.
