In recent days, the outdoor temperature has increased, from 36 - 38 degrees Celsius, sometimes even up to 40 degrees Celsius, causing many workers to feel tired and exhausted, especially those who have to work outdoors. Therefore, protecting the health of workers during hot days has been and is being given top priority by units and businesses.
Due to the production characteristics of the Sin Quyen Copper Mine Branch, Lao Cai - VIMICO, workers in the workshops are greatly affected by the weather, especially those who often have to work outdoors in the mining area and open-pit mine waste dump. Hot weather, temperatures up to 39 - 40 degrees Celsius have reduced the working spirit of workers, significantly affecting labor productivity.
Mr. Bui Nam Thai, a worker at the Repair Team, Transport Workshop, said: I have been working here for more than 10 years, but I have never had a summer as hot and early as this year. The average temperature in recent days has reached 38-39 degrees Celsius, sometimes even reaching 40 degrees Celsius, while when vehicles are brought into the workshop for repair, the heat from the operating machinery and equipment pushes the temperature up even higher, making repairs even more difficult. There is no other way, we have to wait for the machinery and equipment to "cool down" before starting the repair.
Faced with the difficulties faced by workers due to the heat, the Transport Workshop (Branch of Sin Quyen Copper Mine, Lao Cai - VIMICO) has had many solutions to avoid the heat and protect the health of workers. Mr. Vu Duc Trinh, Manager of the Transport Workshop said: The workshop has 220 staff and workers, of which 206 are direct workers, including 180 drivers and 26 repairmen. While the drivers benefit from the cooling system of modern equipment equipped on the vehicle, the repairmen have to face and be greatly affected by the weather.
Faced with the intense heat, the Workshop has added an industrial fan system and adjusted working hours accordingly without affecting labor productivity. Accordingly, working hours are shortened during peak heat, working hours are extended in the afternoon and night shifts are increased. When the temperature is too high, heavy work such as changing tires, repairing shock absorbers, hubs, and engines will be done entirely during the night shift, while the day shift will only do light work so as not to affect health.
Not only the Transport Workshop, but also the Mining Workshop and the Mineral Selection Workshop (Sin Quyen Copper Selection Branch, Lao Cai - VIMICO) have urgently deployed preventive measures to protect the health of workers in the current hot weather. Accordingly, the workshops have increased fans, provided cool air systems to each worker's position, used air conditioning systems (if possible); used supporting machinery and equipment (pulleys, vehicles for transporting heavy objects, etc.) to reduce heavy work for workers.
Proactively change working hours to suit the work of workers who have to work outdoors; rotate work between workers working in hot and non-hot locations (if possible) to reduce the time workers are exposed to high temperatures while working.
Mr. Tran Trong Quynh, Deputy Director of Sin Quyen Copper Mine Branch, Lao Cai - VIMICO affirmed: With the motto "The health of workers is the most important", therefore, during the peak hot days, the Branch has directed the workshops to strictly arrange reasonable working hours, limiting the arrangement of workers to work outdoors from 12:00 to 14:00 on extremely hot days.
Along with that, fully equip personal protective equipment and heat protection equipment (protective clothing, hats, conical hats, shoes, boots, etc.); improve meal quality, increase dishes suitable for hot weather, ensure food hygiene and safety; provide enough cooling drinks (cooling tea, black bean tea, soy milk, fruit juice, etc.).
Strengthen the cooling system (air conditioners, fans, industrial fans, etc.), sunshade and insulation equipment (canopies, curtains, etc.) at work locations with high temperatures (air compressors, power stations, processing areas related to welding and cutting metal with gas and oxygen); spray water to cool the roof of the factory; increase the frequency of watering to prevent dust on the routes transporting soil, rocks, ores, and the section of Provincial Road 156 passing through the mine; operate the misting system to suppress dust and collect dust installed at the mineral processing plant;
An important solution that the Branch focuses on implementing is to organize training, education, and widely disseminate information about the signs, symptoms, and risks of occupational heat stress; and first aid when a colleague faints or suffers heat shock for workers.
During the hot days, working at tunnel brick factories is a real challenge and extremely hard work. Due to the nature of the work, the actual temperature in the brick factory is always 5 to 7 degrees Celsius higher than the outside temperature. Most of the brick making stages from transporting raw materials, shaping, stacking, loading and unloading... are greatly affected by the weather.
Mr. Nguyen Hoang Thin, Manager of Tan An Tunnel Brick Factory (Tan An Construction Ceramic Materials Production Joint Stock Company) said: Summer is the most difficult and strenuous time for brick factory workers. Therefore, the factory has proactively taken many solutions to improve working conditions, ensuring the health of workers during the hot season. During peak heat waves, the factory has invested in strengthening the cooling fan system in production departments; at the same time, adjusting working hours to suit the weather, working earlier in the morning and later in the afternoon so that workers do not have to work during peak heat hours. In addition, the factory continuously replenishes drinking water at work locations, supports soft drinks, and provides full protective clothing.
Not only the Sin Quyen Copper Mine Branch, Lao Cai - VIMICO or Tan An Tuy-nel Brick Factory, but most of the enterprises and production units in the province have been having many solutions to improve working conditions and protect the health of workers during the peak hot days. The specific and practical actions of the units and enterprises have shown their concern and care for the health, improved the material and spiritual life of workers, ensured stable production and work efficiency. This is also the motivation for each worker to actively work and produce, contributing to the development of the unit and enterprise.
Some necessary notes when working outdoors in hot weather:
Experts recommend that people who have to work in hot weather should arrange their working time during the coolest times of the day, such as early morning or late afternoon. Limit working time in high temperature environments. If you have to work, do not work too long in hot environments, avoid strenuous physical activities. Periodically, after about 45 minutes to 1 hour of work, rest in a cool place for about 15 - 20 minutes.
Minimize the area of sunlight exposure to the body, especially the shoulders and neck. Use appropriate personal protective equipment when working outdoors in the sun such as protective clothing, hats, caps, and glasses. Wear loose, cool, and sweat-absorbent clothing. You can also use sunscreen. Do not use alcoholic beverages. You need to drink water regularly during work hours. In particular, you need to provide adequate nutrients and vitamins to keep the body healthy and increase resistance.
