1. Serve drinks and supplement nutrition:

Workers working at high temperatures should supplement the amount of water and salt that is equal to the amount of sweat. The best way to add water and salt is to supply salty drinks. Usually, the water supply is 3-5 liters per person per day and about 20 grams of salt. When the amount of sweating is less than 4 liters within 8 hours of working days, 15-18 grams of salt can be taken from food every day.

If the amount of sweat exceeds this number, besides ingesting salt from food, it is necessary to add a proper amount of salt from the drink. The salt content of the beverage is preferably 0.15%-0.2%. It is advisable to use drinking water in small quantities several times.

When working in a high-temperature environment, energy consumption increases, so the total dietary calories should be higher than the average worker, and it is best to reach 12600-13860 kJ. It is advisable to increase the protein to 14%-15% of the total calories. In addition, vitamins, calcium, etc. can be supplemented.

2. Personal protection:

Work clothes for high-temperature workers should be made of a fabric that is heat-insulating, has a small thermal conductivity and good air permeability. To prevent radiant heat, uniforms made of white canvas or aluminum foil can be used. High-temperature work clothes should be wide and do not interfere with operation.

In addition, according to the needs of different operations, provide work caps, protective glasses, masks, gloves, shoe covers, leg guards and other personal protective equipment. Special high-temperature workers, such as furnace lining hot repair, ladle cleaning and other types of work, in order to prevent the strong heat radiation effect, must wear a heat insulation mask and wear thermal insulation, flame retardant, ventilated thermal protective clothing, such as spraying metal (copper, silver) Thermal insulation masks, aluminum thermal insulation clothing, etc.
