?The summer construction climate is hot, and construction workers generally work in the open air and at high places. The labor intensity is high and the time is long, and heatstroke accidents may occur at any time. Therefore, strengthening heatstroke prevention and cooling in summer is an important measure to protect the health of employees and ensure the completion of production tasks.
?1. Basic safety requirements for preventing heatstroke accidents
?Adopt comprehensive measures to effectively prevent the occurrence of heatstroke accidents, and do a good job in heatstroke prevention and cooling from technology, health care, xx and other aspects Work.
?2. xx measures
?1. Strengthen the leadership of heatstroke prevention and cooling work, formulate a heatstroke prevention and cooling plan and implement specific measures before the onset of summer heat.
?2. It is necessary to strengthen the education of all employees on heat stroke prevention and cooling, and enhance their ability to prevent heat stroke and work-related injuries. Pay attention to maintaining adequate sleep time.
?3. Work and rest schedules should be appropriately adjusted according to local temperature conditions. Use methods such as working in the morning and evening when the temperature is lower, and extending rest time to reduce solar radiation heat to prevent heat stroke. The labor force can also be reasonably adjusted according to the construction technology, shorten the one-time operation time, and increase the rotation rest during the construction process.
?4. Implement the "Labor Law" and control overtime work; strengthen the management of workers' dormitories; effectively combine work and rest to ensure that workers eat, sleep and rest well.
?3. Technical measures
?1. Carry out technological innovation, reform processes and equipment, and use mechanization and automation as much as possible to reduce the labor intensity of the construction industry.
?2. Set up a rest room in an open-air construction site where workers are concentrated. The room should be well ventilated and the room temperature should not exceed 30°C. When the open-air operation on the construction site is relatively fixed, movable curtains or pergolas can also be used. Reduce solar radiation.
?3. When operating underground, try to use natural ventilation skylights for exhaust and side windows for air intake. Mechanical ventilation measures can also be used to deliver cool air to high-temperature operating points or remove hot air to reduce Workshop temperature.
