Final answer:
Steel-toed boots and metatarsal guards are required foot and leg protection for welding operations where objects could fall on a welder's toes.
Step-by-step explanation:
When objects could fall on a welder's toes during welding operations, foot and leg protection is required to prevent injuries. One type of foot and leg protection commonly used in welding is steel-toed boots. Steel-toed boots have a reinforced toe cap that provides protection against impacts from falling objects. These boots are designed to withstand heavy impacts and compression.
Another type of foot and leg protection that may be required in certain situations is metatarsal guards. Metatarsal guards are additional protective devices that cover the instep and metatarsal bones of the foot. They provide extra protection from crushing hazards and impacts.
Both steel-toed boots and metatarsal guards are important to ensure the safety of welders in environments where objects can fall on their toes during welding operations.
