How to adjust the working hours in high temperature construction sites

Construction work is a very hard job, and in most cases people have to work outdoors. If people work outdoors in the hot summer, it is not only hard, but if they do not pay attention to their physical condition, they may suffer from heat stroke. Therefore, when the temperature on the construction site reaches high temperatures, the work and rest time needs to be adjusted. Here we will introduce how to adjust the work and rest time on the construction site during high temperatures.

During extremely hot summers, you should prevent heat stroke when working outdoors. It requires construction units on construction sites to adjust working hours and avoid high-temperature operations.

Summer high temperature avoidance work and rest schedule

7:00am - 11:00am

Afternoon 15:00 – 19:00

How to prevent heat stroke when working outdoors:

1. Properly arrange construction and production during high temperatures and reasonably adjust working hours. Pay close attention to weather forecasts related to high temperature weather. (Meteorology defines a "high temperature day" as a day with a maximum daily temperature greater than or equal to 35°C, and more than five consecutive "high temperature days" are called "continuous high temperature.") In principle, if the maximum daily temperature reaches above 40°C, outdoor work should be stopped for that day; when the maximum daily temperature is above 35°C and below 40°C, outdoor and high-altitude work is not allowed between 11:00 and 16:00. Strictly control overtime work to prevent injuries and deaths caused by workers’ fatigue and overwork.

2. Strictly provide workers with heatstroke prevention and cooling items and medicines. The construction site should ensure an uninterrupted supply of boiled water and mung bean soup, and should provide sufficient light salt water that meets hygienic requirements to prevent workers from dehydration and heatstroke. The construction site should be equipped with necessary anti-heat medicines such as Ren Dan, Shi Di Shui, Huoxiang Zhengqi Shui, Qingliang Oil, etc., as well as a medical kit. Anti-heat medicines should be distributed in sufficient quantities and on time to each team and front-line workers.

3. For construction site managers, they should adjust the labor organization as much as possible during the hot summer, adopt shift work to shorten the continuous working time, and strengthen rotation and rest during work. People with organic cardiovascular diseases, hypertension, organic central nervous system diseases, obvious respiratory, digestive or endocrine system diseases, and liver or kidney diseases should not engage in high-temperature work.
