The hazards of heavy fog and measures to prevent accidents. The harms of heavy fog to humans: 1. It affects the traffic safety of employees on their way to and from work; due to the thick fog, vehicles cannot drive properly, which can also lead to road accidents within industrial areas； 2 Due to high air humidity, the waste hot water discharged from the production units releases large amounts of water vapor in the open channels; this vapor mixes with the dense fog, resulting in insufficient lighting in the operating environment and compromising the safety of workers in the chemical production area ； In conditions of heavy fog, where visibility is very low, sometimes as low as around 10 meters, the environment at the site where maintenance work is carried out becomes even worse, increasing the risk of injuries caused by falling objects as well as safety accidents related to lifting operations ； 4 pairs show increased metal corrosion. Since fog droplets contain substances such as sulfur dioxide and hydrogen sulfide, which are corrosive to metals, they pose a serious threat to exposed metal. According to statistics, tens of millions of tons of steel are corroded by dense fog each year worldwide ； 5 It causes air pollution. Due to the strong adsorptive properties of fog, as it moves at low altitudes, it continuously collides with pollutants, causing them to accumulate and increasing the concentration of harmful substances in the fog. Studies have shown that the levels of acids, amines, phenols, heavy metal particles, dust, and microorganisms in fog droplets are dozens of times higher than those in normal air, posing a significant threat to human health. Breathing polluted fog leads to a significant increase in respiratory diseases. Precautions against accidents in foggy weather: To mitigate the hazards caused by fog, in such conditions it is necessary not only to strengthen traffic control within the factory premises and raise employees’ awareness of safety while working, but also to take measures to ensure safety by providing proper safety training to employees and ensuring that they wear appropriate personal protective equipment. 1 Strengthen control over factory premises and road traffic to prevent road traffic accidents. Severe fog in winter has a significant impact on vehicle driving. There are at least 8 aspects that drivers should pay attention to when driving in foggy conditions in order to ensure safety: Before setting out, the windshield, headlights, and taillights should be wiped clean, and it is necessary to check that all safety features such as the vehicle’s lights and braking system are in good working order. Additionally, it is essential to carry a triangular warning sign or other warning markers in the vehicle. When the vehicle needs to be stopped for repairs due to an unexpected malfunction, such signs should be placed 50 meters in front of and behind the vehicle to alert other drivers ； Keep your distance from other vehicles. When driving in fog, it is advisable to drive at a low speed, especially by maintaining a sufficient safety distance from the vehicle ahead and avoiding following too closely. Try to drive as close to the center of the road as possible, and avoid driving along the roadside to prevent collisions with people who have parked there temporarily waiting for the fog to clear ； When driving in fog, it is essential to strictly adhere to traffic rules and speed limits; under no circumstances should you drive fast or rush down slopes. The thicker the fog, the shorter the visibility, and the lower the speed must be. Experts recommend that when visibility is less than 200 meters but greater than 100 meters, the speed should not exceed 60 kilometers per hour ； When visibility is less than 100 meters but greater than 50 meters, the speed must not exceed 40 kilometers per hour ； When visibility is 30 meters or less, the speed should be kept below 20 kilometers per hour ； When visibility is around 10 meters, the speed must be strictly kept below 5 kilometers per hour ； Do not use high beams. Because the axis of the high-beam lights is positioned high, the light emitted is reflected by the fog, creating a white haze in front of the vehicle; as a result, the driver can see nothing at all. When driving in fog, it is essential to use fog lights, and it is necessary to follow the rules regarding their use: turn on the front and rear fog lights, tail lights, side marker lights, and low-beam headlights. These lights help improve visibility, allowing one to see the vehicles and pedestrians ahead as well as the road conditions, while also making it easier for others to see one’s vehicle ； Use the horn frequently. In foggy conditions with poor visibility, honking the horn frequently can serve to warn pedestrians and other vehicles. When hearing the horns of other vehicles, one should immediately respond by honking as well to indicate one’s location on the road. When two vehicles pass each other, the driver should honk the horn to alert the vehicle on the opposite side, and at the same time turn off the fog lights to avoid causing glare for the other driver. If the other driver is going fast, one should take the initiative to slow down and give way ； Pull over at the appropriate time. If the fog is too thick, you can pull the car over and turn on the low-beam headlights as well as the hazard lights. After stopping, get out of the vehicle on the right side, secure the wheels, and move as far away from the road as possible. Never stay in the car, as you could be hit by passing vehicles. Wait until the fog clears or visibility improves before setting off ； Never overtake blindly. If you see a vehicle ahead parked on the right side, do not try to bypass it blindly; consider whether that vehicle is waiting for traffic coming from the opposite direction. When overtaking a vehicle parked by the side of the road, make sure it has no intention of starting and that there are no oncoming vehicles; then honk the horn at the appropriate time and pass it at low speed from the left. Also, please be careful to keep a close eye on the lane markings on the road and avoid driving outside of them, as this could lead to a collision with oncoming vehicles. When driving on curves and slopes, reduce speed in advance; avoid changing gears, stopping, or turning off the engine midway ； Don’t brake suddenly. When driving in fog, it is generally advisable not to step on the accelerator hard or release it quickly, and certainly avoid sudden braking or sharp turns with the steering wheel. If it is felt that it is necessary to reduce the speed, first gently release the accelerator, then press the brake lightly several times in a row to control the speed and prevent rear-end collisions. Conduct safety education for 2 pairs of employees to continuously enhance their awareness of safety when working in foggy conditions. All units should use platforms such as the scheduling meeting notices, safety reminder boards, pre-shift and post-shift meetings, as well as regular safety meetings, to educate employees and remind them of safety measures in foggy conditions ； All units should strengthen education on traffic safety for employees who commute by motorcycle, requiring them to wear helmets and drive at a safe speed; at the same time, they should increase inspections to ensure that employees comply with these rules ； Units such as the raw material workshop, gas production workshop, and boiler workshop should place particular emphasis on providing safety training to their employees to prevent accidents caused by vehicles during work. Whether inside or outside the factory, employees must use crosswalks when crossing roads, avoid jaywalking, and refrain from competing for passage; at the same time, they need to take precautions to avoid collisions with vehicles ； The small fleet and support fleets should strengthen employees’ training on the safety precautions for driving outlined in the \"Compilation of Hazard Identification Factors\", to ensure safe driving throughout the journey. Turn on the front and rear fog lights while driving; if you don’t have fog lights, use the low beams, but avoid using the high beams. Control your speed, maintain a sufficient braking distance from the vehicle ahead, drive slowly – never drive too fast – and use the horn frequently to warn pedestrians and other vehicles. Keep your eyes fixed on the road ahead and never lose track of your direction. Remove fog from the windshield promptly. When stopping in fog, pull over as close to the roadside as possible, ideally off the road itself. Turn on the fog lights and do not stay inside the vehicle. 3 At the site of internal inspection and maintenance work within the company, safety education and briefing prior to the work must be carried out; personnel arrangements must be implemented properly, along with proper coordination and on-site supervision. In sites where vertical cross-work takes place, it is necessary to take measures to prevent tools and other items from falling, to tidy up the area where maintenance work is carried out on a regular basis, and to ensure that everything in the site is in order ； Large-scale lifting operations are prohibited in conditions of low visibility due to heavy fog; professional supervisors must be used for pulling and filling operations, with clear and unified command signals. Regarding the use of health and protective equipment by 4 people, it is advisable to avoid going outside as much as possible on foggy days; close doors and windows, and open them for ventilation only once the sun comes out and the fog clears. When going outdoors on foggy days, wear a mask to prevent pollutants from entering the body through the respiratory tract.
