The meteorological feature of high temperature and high humidity operation is ().

The meteorological characteristics of high temperature and high humidity operation are high temperature, high relative humidity, small airflow and weak thermal radiation, forming a hot and humid environment.

Expand knowledge:

I. Introduction to High Temperature Operation:

Working in high temperature environment refers to working under abnormal working conditions such as high temperature, strong thermal radiation or high air humidity (relative humidity ≥80%RH) and wet bulb temperature index (WBGT index) exceeding the specified limit. Including high temperature weather operations and high temperature operations in the workplace.

Second, classification

1, high temperature and strong thermal radiation operation: coking, ironmaking, steelmaking and other workshops in metallurgical industry; Foundry workshop of machinery manufacturing industry; Kiln workshops in ceramics, glass and building materials industries; Power plant (thermal power station), boiler room of gas plant, etc.

2. High temperature and high humidity operation: textile printing and dyeing factory; Shenjing coal mine

3. Open-air operations in summer: construction sites, large-scale sports competitions, etc.

Third, protective measures.

First, improve working conditions and equip with protective facilities and equipment.

Water insulation: Common methods include water tank or circulating water furnace door, waterfall water curtain, etc.

Use thermal insulation materials: commonly used materials are asbestos, slag, grass ash, foam bricks, etc. This method is the best in factories and small and medium-sized enterprises that lack water.

Adopt natural ventilation: such as skylight, open workshop, or install hood on the roof.

Mechanical ventilation: such as fan and post air supply. Install air conditioning equipment.

Second, strengthen personal protection.

Personal protective equipment: Work clothes should be made of strong, heat-resistant and breathable fabrics, and work caps, protective glasses and masks should be provided according to the needs of different operations. Such as blast furnace operation, you must wear heat shield and heat-proof clothing with good heat insulation and ventilation.

Third, strengthen medical care and health monitoring.

From the point of view of prevention, it is very necessary to do a good job of physical examination for high temperature workers before employment and in summer. Those who have high temperature contraindications such as cardiovascular diseases, central nervous system diseases and digestive system diseases are generally not suitable for high temperature operation and should be given corresponding prevention and treatment.

Provide refreshing drinks, cooling products and supplementary nutrition for heatstroke prevention and cooling: Salt soda, mung bean soup, soybean milk and sour plum soup should be selected for high-temperature drinks, and the drinking method should be small and multiple times. Towels, essential balm, Huoxiang Zhengqi water, Ren Dan and other heatstroke prevention and cooling products can be prepared. In addition, to establish a reasonable dietary system, protein and calories, vitamins A, B 1, B2, C and calcium should be supplemented in the diet.
