What are the injuries to the foot? How to use protective equipment?

(1) Factors that cause foot injury in the production process

a. Object bruises or stabs: This is the most common factor. In machinery, metallurgy and other industries and construction or other constructions, often falling objects, throwing objects or nails and other sharp objects scattered on the ground, may bruise the toe or stab the foot.
b. High and low temperature damage: In some workplaces such as smelting, foundry, metal processing, coking, and chemical industries, strong radiant heat can cause foot to burn, and burning materials may fall on the feet and cause burns or burns. In cold areas, especially during outdoor construction in winter, the foot may suffer frostbite due to cold temperatures.
c. Chemical Injury: In the chemical, paper, textile, and other industries exposed to chemicals (especially acid and alkali), there may be accidental chemical burns on the feet.
d. Electrocution and Electrostatic Injury: On the one hand, the human body's hands and feet are parts that are prone to electrical shock; on the other hand, workers who do not wear electrical insulating shoes may cause electrical shocks; or because the material of the soles of the workers is not appropriate, When walking, it may rub against the ground and generate static electricity, causing harm.
