With the arrival of winter, the weather becomes cold and dry, prone to personnel frostbite, poisoning, slipping and other personal injury accidents, fire, explosion accidents and traffic accidents, but also prone to frost cracking equipment and process pipelines and other production accidents. Therefore, measures should be implemented in winter to prevent personal injury accidents, fire and explosion accidents, traffic accidents, and do a good job of anti-freezing and anti-coagulation of installation pipes, equipment and valves to ensure the safe production of steel mills in cold winter.
Characteristics and hazards of safe production in steel mills in winter
1, the weather is cold, clothing is bloated, people's hearing, vision, action will be affected to a certain degree, coupled with rain and snow weather, it is very easy to cause frostbite, slipping and other personal injury accidents.
2, low temperature deformation and rupture of equipment and metal components, easy to lead to leakage, explosion, fire, poisoning and equipment production accidents.
3, winter in a cold high-pressure state, toxic and harmful gases are easy to accumulate, coupled with winter insulation, easy to cause poisoning and fire and explosion accidents.
4, winter dry things, whether it is the human body or equipment, facilities, easy to produce static electricity and cause fire, explosion and personal injury accidents.
Prevention of personal injury
1. Prevent frostbite
The company (enterprise) has done a good job of heating the tea installation area according to the local climate characteristics, and has also equipped everyone with personal labor protection products such as cotton clothes and cotton hats to keep warm. Employees in the work should be properly worn according to the requirements of the cold clothing to tie the collar, cuffs, cold helmet to tie the hat band.
2, anti-slip
Various stairs and roads on the production post are easy to freeze when they encounter rain or snow, and employees are easy to slip and fall when they go up and down the ladder or walk. Therefore, attention should be paid to timely cleaning the ladder or inspecting the rain or snow on the road, especially the stairs on the device, most of which are steel frames, and it is easy to cause injuries caused by falling. Outdoor climbing operations, to strictly check the equipment, facilities, increase the necessary anti-skid measures. Climbing operators should put their feet smoothly, grasp the handrail, and do not put their hands in their pockets or back hands down the ladder.
3. Prevent poisoning and suffocation
First, due to the cold winter, the door of the operation room of the device area is generally more strict, which is easy to cause the concentration of toxic gases such as carbon monoxide, so it is necessary to regularly do ventilation. The second is to strengthen the inspection of gas supply pipelines to prevent flammable gas from gathering indoors. The third is to strengthen the safety education of workers against poisoning and popularize the knowledge of self-rescue and calling for help.
Fire and explosion prevention
1, strengthen fire safety education for employees, especially in areas with flammable and explosive devices, should strengthen fire management, minimize the frequency of fire action operations in strict accordance with the procedures for fire operation tickets, fire operation can be carried out under the conditions of safety fire prevention and monitoring personnel.
2. Strengthen post inspection to prevent fire and explosion material leakage. Do not wear chemical fiber clothing into the device area, before the tank sampling and other operations, to touch the static electricity elimination facilities, so that static electricity can be released.
3, do not use electric heating equipment at work, do not pull temporary wire. It is required to use electrical equipment to prevent overload, and the used electric heating equipment should be powered off in time to prevent fire caused by electricity.
4, to ensure that fire facilities and equipment complete, good and effective, after entering the winter, to do a good job of anti-freezing work on the basis of ensuring that the fire facilities and equipment in a standby state.
Traffic accident prevention
1. Organize drivers to learn safe driving precautions before winter, and do a good job of safe driving education in severe weather such as cold, strong wind, thick fog, and heavy snow.
2, according to the characteristics of the model and the implementation of the task to develop anti-freeze, anti-slip, anti-fog and other specific measures.
3, do a good job of seasonal maintenance of the vehicle, the use of lubricants and brake fluid in line with the use of winter, the engine and radiator shell to install cold insulation cover, especially the brake system, steering system, lighting system must be intact and reliable to ensure that the vehicle is in good condition. Carry out comprehensive inspection and maintenance of the technical condition of the vehicle, so that it is in good condition.
4, according to the requirements of timely replacement of vehicle antifreeze and the corresponding label of oil, fuel oil.
5. Driving on ice and snow roads should control the speed, prohibit high-speed driving, avoid emergency steering and emergency braking, and allow no quick acceleration or quick retract the accelerator. Serious snow and ice roads should be equipped with anti-skid chains, the vehicle should maintain the driving distance, and properly lengthen the vehicle distance to reduce the speed, to prevent the occurrence of rear-end accidents. Snow, snow, fog and other bad weather try not to send long-distance buses.
Winter installation pipeline, equipment valve anti-freeze and anti-coagulation
1, the pipeline should use the fluid circulation in the system as much as possible to prevent freezing to avoid temporary additional heat. For example, in the circulating cooling water system, when the equipment is stopped for a short time, the circulating water in each condenser can be reduced and maintained. For unavoidable dead corners, heat preservation or anti-freezing with heat should be used.
2, the use of exhaust antifreeze, for water, condensate and steam and other public engineering pipelines, liquid accumulation and freezing may occur when stopping, antifreeze should consider the appropriate discharge, emptying and self-discharge. These lines should be completely drained during shutdown or decommissioning.
