With the arrival of winter, the weather becomes cold and dry, which is prone to personal injury accidents such as frostbite, poisoning, sliding, fire, explosion and traffic accidents, as well as production accidents such as frost cracking equipment and process pipelines. Therefore, measures should be taken to prevent personal injury accidents, fire and explosion accidents and traffic accidents in winter, and to prevent freezing and condensation of pipes, equipment and valves in order to ensure safe production in cold winter.

1. freeze injury

The company (enterprise) has done a good job of heating the raw tea plant area according to the local climate characteristics, and also equipped you with personal protective equipment such as cotton clothes, cotton caps and so on. Employees should wear cold-proof clothes correctly according to the requirements, wear tight collars and cuffs, and wear hard-hat belts.

2. skid resistance

Various stairs and roads on production posts are liable to freeze when encountering rain or snow, and workers are liable to slip and fall when they go up and down ladders or walk. Therefore, attention should be paid to timely cleaning of rainwater or snow on ladders or patrol roads, especially stairs on installations, most of which are steel frames, which can easily cause falls and lead to injury. In outdoor climbing, equipment and facilities should be strictly checked and necessary anti-skid measures should be added. The climbers should keep their feet steady, hold the handrails firmly, and strictly forbid putting their hands in their pockets or backhands to go up and down the ladder.

3. Prevention of poisoning and asphyxia

Firstly, because of the cold winter, the doors of the operating rooms in the installation area are generally tight, which easily causes the accumulation of toxic gases such as carbon monoxide. Therefore, ventilation and ventilation should be done regularly. The second is to strengthen the inspection of gas supply pipelines to prevent the accumulation of combustible gases indoors. Thirdly, we should strengthen the safety education of workers against poisoning and popularize the knowledge of self-help and call for help.

Preventing fire and explosion

1. To strengthen the fire safety education of employees, especially in the areas where flammable and explosive devices exist, fire management should be strengthened, and fire operation tickets should be handled strictly in accordance with the procedures when the frequency of fire operation is minimized. Fire operation can be carried out under the conditions of complete preparation for fire safety and fire protection and guardians.

2. Strengthen post inspection to prevent leakage of fire and explosive substances. It is forbidden to wear chemical fiber clothing into the installation area. Before sampling in the upper tank, we should first touch the facilities to eliminate static electricity, so that the static electricity can be released.

3. Don't use electric heating equipment and pull temporary wires in your work. Provisions are made for the use of electrical equipment to prevent overload. Used electric heating equipment should be cut off in time to prevent electricity from causing fire.

4. Ensure that fire fighting facilities and equipment are complete, intact and effective. After entering winter, we should ensure that all fire fighting facilities and equipment are in standby state on the basis of doing a good job of anti-freezing work.

Prevention of traffic accidents

1. Organize drivers to learn the precautions for safe driving before winter, and do a good job of safety driving education in severe cold, gale, fog, Blizzard and other bad weather.

2. According to the vehicle type and the characteristics of the task, specific measures such as anti-freezing, anti-skid and anti-fog are formulated.

3. Carry out seasonal maintenance of vehicles, use lubricants and brake fluids suitable for winter use, and install cold-proof thermal insulation cover for engine and radiator shell, especially for brake system, steering system and lighting system, so as to ensure that the vehicles are in good condition. Carry out a comprehensive inspection and maintenance of the technical condition of the vehicle to keep it in good condition.

4. Replace vehicle antifreeze fluid and corresponding marked engine oil and fuel oil in time as required.

5. On ice and snow road, we should control the speed well, prohibit high-speed driving, avoid emergency steering and braking, and prohibit acceleration and acceleration. Anti-skid chains should be installed on severe ice and snow pavement. Vehicles should keep their driving distance while traveling, and properly lengthen their distance to reduce their speed so as to prevent rear-end accidents. Don't send long-distance buses in bad weather such as ice, snow and fog.

Chemical Plant Antifreeze Knowledge

1. Do a good job of personal protection, wear warmth, and do a good job of anti-skid work of the upper tower and the lower tower in the process of equipment inspection.

2. Strengthen the dewatering work and drain the water in each dewatering point in time to prevent freezing blockage.

3. Attention should be paid to the fact that there is a frozen plug in the upper and lower corner valves of the instrument level gauge on site, which will affect the real level. The frozen plug on the head of the remote level gauge will affect the mechanical rotation, current conduction and the real level.

4. The temperature of circulating water is not easy to control too low, not less than 8 degrees. When the temperature is lower than 8 degrees, it will cause the freezing blockage of the secondary line of cooler, and freeze-crack the pipeline seriously.

5. Insulation of the pipeline in the dead water area of the circulating water in the workshop; backflow measures are adopted for the discontinued circulating water pumps, and they are discharged clean.

6. Workshop outage equipment, such as water supply pumps, circulating pumps, coolers, condensers, etc., should adopt measures such as drainage, regular patrol inspection and so on. Compressor cooling water is inspected regularly by operators to ensure that the water valve keeps open.

7. If the liquid hydrocarbon pipeline is frozen and blocked, when steam sweeps the pipeline, pay attention to physical explosion, do not force sweeps, warm up slowly.

8. On-site pressure gauge in the case of freeze-blockage will also appear false, according to experience to judge. If it is uncertain, it should be reported and processed in time.

9. When sweeping the frozen blocked pipeline, sweep the elbow with steam.

10. Attention should be paid to strengthening dehydration of natural gas pipelines so as not to bring liquids into boilers. Check the natural gas line to prevent unobstructed crystal structure caused by freezing.

11. Strengthen patrol inspection to check the temperature at all points.

12. The raw water pipeline should avoid closing and keep long flow.

13. Closed equipment, pipelines and production systems should be connected with blind plates and drainage of water.
