Fourth, ventilation and cooling, in addition to natural ventilation, mechanical ventilation optional fan, spray fan, fully or partially centralized air cooling system.
Second, improve health care. Reasonable health care measures that can improve the physical condition of high temperature operations personnel, improve work efficiency, prevent heat stroke and other accidents, and reduce the long-term effects on the body temperature.
1. Strengthen Health Care. In addition to pre-employment medical examination before the summer and summer, to observe the dynamic state of health workers in high-temperature, high temperature found employment contraindications, should be transferred from their posts.
2. Strengthen personal protection. Overalls should be large, light and without prejudice to the operation, should adopt firm texture, heat, thermal conductivity, good air permeability, and can reflect heat radiation fabric. According to the needs of different jobs, with work hat, protective glasses, gloves, shoe covers, leggings and other personal protective equipment.

5. Strengthening nutrition. When working in a hot environment, energy and protein consumption than more, so should eat high-calorie, high protein, high vitamin diet, total calories than the average person should be up about 15%, moderate physical labor daily 3300-3500 kcal, heavy manual workers daily 4000-4500 kcal. In the daily diet should be a higher proportion of the nutritional value of animal vegetable protein, eat more fresh vegetables and fruits, attention to vitamin A, B1, B2, C and other water-soluble vitamins and potassium, calcium, magnesium and other minerals substance.
