Criteria for judging high-temperature jobs

Legal analysis: The grading standard of high-temperature operation is to divide high-temperature operation into four grades according to WBGT index of workplace and high-temperature operation time. The higher the grade, the greater the thermal strength. The average directional radiant heat intensity in the workplace is greater than or equal to 2kW/, which should be increased by one grade on the basis of the grading level in Table 5-6, but the maximum shall not exceed Grade 4.

Legal basis: Article 17 of the Administrative Measures for Heatstroke Prevention and Cooling Measures. If the employing unit arranges laborers to engage in outdoor open-air operations in hot weather above 35℃ and cannot take effective measures to reduce the workplace temperature below 33℃, it shall pay high-temperature allowance to the laborers and include it in the total wages.
