高温作业的气象条件标准必须是以保护工人的身体健康为前提,同时在工程技术措施上也应该是切实可行的。因此气象条件标准的制定要综合考虑卫生、经济及工程技术等方面的因素。现行的卫生标准,是根据室外夏季通风计算温度的不同,规定了工作地点与室外温差的允许值。这就是说采用单一干球温度作为标准,这样既不能反映各种气象条件的综合
The standard of meteorological conditions for high-temperature operation must be based on the protection of workers’ health, and at the same time it should be feasible in terms of engineering and technical measures. Therefore, the formulation of meteorological conditions should take comprehensive consideration of factors such as health, economy and engineering and technology. The current health standards stipulate the allowable value of temperature difference between working place and outdoor according to the difference of outdoor summer ventilation temperature. This means that using a single dry-bulb temperature as a standard, so neither can reflect the comprehensive meteorological conditions
