What safety equipment is essential when performing welding?

The correct choice identifies essential safety equipment for welding, which is critical to protect the welder from various hazards associated with the process. A welding helmet is designed to shield the eyes and face from the intense light produced during welding, as well as UV and IR radiation. Gloves are vital for protecting hands from extreme heat and sparks, while protective clothing helps prevent burns and injuries from molten metal. Proper footwear, such as steel-toe boots, is necessary to protect feet from heavy falling objects and also provides a non-slip surface to prevent falls in the workplace. This comprehensive set of equipment ensures safe practices while performing welding tasks, which is paramount in such a hazardous environment.
