First of all, operators under high temperature must wear helmets and fasten safety belts to avoid safety risks. Work order system is implemented for work at height, and guardians must be arranged at the site of work at height to be responsible for safety confirmation, guardianship, communication and liaison at the site of work, and must not leave the site during the operation. The operation must be approved before, after approval before work; personal protection should be done. The hooks of safety belts or safety ropes must be hung on strong and firm components and used at high altitude.
Secondly, attention is paid to preventing the use of excessive electricity, wires transformers and other electrical loads caused by fire. Supervise enterprises to carry out electricity safety self-inspection and investigation, strengthen the inspection of the old plant electrical equipment; according to the relevant safety regulations for the protection of grounding or zeroing; frequent contact and use of the distribution box, switchboards, knife switches, push-button switches, sockets, pins and wires should be kept intact, shall not be damaged or exposed electrically charged parts, so as to better ensure that the risk of safety at the time of the operation. Ensure their own safety.
Develop a heat stroke prevention emergency plan, carry out heat stroke prevention training, and do a good job of confirming the physical condition of the duty personnel before going on duty. Every day, check whether the air conditioner and fan in the server room are running normally, and check whether the thermometer in the server room is within the range of 5-40℃. Check the car every day to feel whether the ventilation fan is running and whether the airflow is normal. Ask the maintenance unit is often retained wearing parts, in the spare parts damage can provide spare parts in a timely manner to ensure that the elevator in a timely manner to replace, damage, the elevator can be put into normal into safe operation.
What you need to know is that when a short circuit occurs in the line, the current in the line will increase to several times or even dozens of times the normal operating current, resulting in a sharp rise in the temperature of the equipment. When the temperature reaches the ignition point of combustible materials, it will cause combustion. There are many reasons for the short circuit of the line, such as the insulation of the energized part of the electrical equipment is damaged, and the equipment is not qualified. The wire joints are not firmly connected, the dynamic contacts are pressurized by the size, etc., which is easy to make the contact resistance is too large, the contact part of the overheating and cause a fire.
