Talking about High Temperature Operation Safety Protection

High-temperature operation is based on the average outdoor temperature in summer in the region as a reference, the workplace has a productive heat source, and the work site temperature is higher than the outdoor temperature of 2 °C and above. The dangerous factors of high temperature environment and the subjective neglect of some operators are all very likely to induce production safety accidents, so it is very important to do a good job of protecting high temperature operations.

The relevant person in charge of the Municipal Safety Supervision Bureau told the reporter that high-temperature operation can be divided into three basic types according to the characteristics of weather conditions. First, high-temperature radiation operation, such as coking, ironmaking, steelmaking, steel rolling, casting, forging, heat treatment, etc., is characterized by high temperature, high heat radiation intensity, low relative humidity, and dry and hot environment. The second is high-temperature and high-humidity operations, characterized by high temperatures and high humidity. In this environment, the body is extremely difficult to evaporate and radiate heat. The body is prone to heat accumulation or water and electrolyte imbalances, causing heat stroke. The third is summer open-air operations such as construction and transportation. In this environment, the heat radiation lasts for a long time. The head is often exposed to direct sunlight. The temperature rises around midday and the body is prone to heat stroke due to excessive heat storage.

It is understood that dizziness, headache, vertigo, tinnitus, palpitations, nausea, weakness in the limbs, inability to concentrate, incoordination and other symptoms, and even sudden fainting or engorgement, may have a greater impact on human health. .

The relevant person in charge of the Municipal Safety Supervision Bureau stated that to do a good job in the safety protection of high-temperature operations, three tasks need to be done. The first is to improve working conditions. Use water tanks or recirculating water furnace doors to insulate water through waterfall water curtains; use asbestos, slag, straw ash, foam bricks and other thermal insulation materials; install skylights or build open-air plants, or maintain natural ventilation in roof-mounted hoods, or Use fans, post air supply for mechanical ventilation; install air-conditioning equipment in high-temperature workshops. The second is to provide necessary protective equipment and summer cooling supplies. To do a good job before the hot work staff and physical examination before the heat, where there are cardiovascular diseases, central nervous system diseases, digestive system diseases and other high-temperature contraindications, generally not suitable for high-temperature operations. Enterprises should provide high-temperature workers with strong, heat-resistant, breathable fabrics to make overalls, and provide work caps, protective glasses, masks, etc. as well as towels, Fengyoujing, Huoxiangzhengqi, Rendan, cool Drinks and other heatstroke cooling supplies. The third is to rationally arrange high temperature and time for summer and strengthen the safety education of high temperature operations. Enterprises should, in accordance with the characteristics of production and specific conditions, ensure the quality of work, and at the same time, properly adjust the hot work and rest system in summer to extend the rest time and reduce the labor intensity. In particular, open-air production companies must avoid hot working hours as much as possible to ensure safe production and the health of employees. In addition, enterprises should strengthen publicity and education on safety production, increase employees' awareness of safe production, and strictly supervise and urge high-altitude workers to wear good safety belts, safety helmets and other protective equipment to ensure safe production.
