Final answer:
The additional safety equipment that must be worn to protect the legs and feet from falling molten metal during overhead welding includes insulated shoes, gloves, and helmets.
Step-by-step explanation:
When performing overhead welding, it is important to wear additional safety equipment to protect the legs and feet from falling molten metal. One important piece of safety equipment is insulated shoes, which provide a large resistance and prevent a pathway for current flow through the feet. Insulated shoes are designed to prohibit electrons from reaching the ground and reduce the risk of electrical shock.
In addition to insulated shoes, welders should also wear other standard safety gear such as gloves and helmets to protect against the thermal energy, sparks, and high-energy electromagnetic radiation produced during welding. These safety precautions are essential for protecting the welder from potential injuries.
