The meteorological characteristics of high temperature and high humidity operation are as follows

The meteorological characteristics of this operation are high temperature, high radiation intensity and low relative humidity, forming a dry and hot environment. People will sweat a lot when they work in this environment. If there is poor ventilation, sweat will be difficult to evaporate, evaporation and heat dissipation will be difficult, and heat storage and overheating may occur. High temperature and high humidity operation. Its meteorological characteristics are high temperature and high humidity, but its radiation intensity is low.

The formation of high humidity is mainly due to a large amount of water vapor produced in the production process, and the production process requires the team to maintain a high relative humidity.

Brief introduction of high temperature operation

Operation in high temperature environment refers to operation 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.

High temperature weather refers to the weather where the daily maximum temperature is above 35℃ released to the public by the meteorological offices and stations affiliated to the competent meteorological departments at or above the prefecture level. Hot weather operation refers to the operation that the employer arranges workers to carry out in a high-temperature natural meteorological environment in hot weather. High temperature operation in the workplace refers to the operation in which the average WBGT index in the workplace is ≥25℃ in the process of production and labor.

protection 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.
