Final answer:
For protection against falling objects or electrical hazards during welding, you should wear a welding helmet with a hard hat.
Step-by-step explanation:
When there is a risk of falling objects or electrical hazards, you should wear a welding helmet with a hard hat. The welding helmet protects the welder from the electric arc, which generates intense thermal energy capable of melting metal and producing sparks, as well as emitting harmful electromagnetic radiation that can damage vision.
In addition to full face protection, it is essential for safety in environments where physical hazards such as falling objects are present, that head protection in the form of a hard hat is worn to prevent head injuries.
