What does not belong to the basic type of high temperature operation?

High humidity and strong radiation is not the basic type of high temperature operation.

1. High temperature operation

High temperature operation refers to the operation under abnormal operating conditions with high temperature, strong thermal radiation, 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.

classify

High temperature and strong thermal radiation operations: coking, ironmaking and steelmaking workshops in metallurgical industry, foundry workshops in machinery manufacturing industry, kiln workshops in ceramics, glass and building materials industries, boiler rooms in power plants (thermal power stations) and gas plants, and other high temperature and high humidity operations: textile printing and dyeing plants, open-air operations in deep wells in midsummer: construction sites, large-scale sports competitions, etc.

3. Working environment

Metallurgical industry, including steelmaking, ironmaking, steel rolling, coking, etc. Casting, forging and heat treatment in machinery manufacturing industry; Kiln workers, furnace workers, etc. In the glass and refractory industries. In addition, there are paper-making, sugar-making, brick and tile industries, power plants, boiler rooms and diving cabins for trains and ships. , all belong to high temperature operation.

4. Industry characteristics

There are high-temperature operations in almost all industries of industrial production, such as steelmaking, ironmaking, paper making, plastic production and cement production. When working at high temperature, a series of physiological function changes will occur in human body. These changes are adaptive responses within a certain range, but if they exceed the range, they will have adverse effects and even cause lesions.

5. Health effects

Regulation of body temperature: Meteorological conditions, labor intensity, working hours and human health during high temperature operation will have an impact on the regulation of body temperature.

Water and salt metabolism: when working at high temperature, perspiration increases obviously, which can lead to the loss of water, sodium oxide, potassium, calcium, magnesium and vitamins. If it is not replenished in time, it will lead to severe dehydration, circulatory failure, thermal spasm and so on. Circulatory system: when working at high temperature, the cardiovascular system is often in a state of tension, which can lead to changes in blood pressure. Hypertension patients increase with the increase of working years in high temperature.
