General knowledge of lightning protection precautions in case of lightning

In case of lightning, pay attention to the following points ★ stay indoors and close the doors and windows. When it is impossible to hide in buildings with lightning protection facilities in the wild, remove metal objects such as watches and glasses, and never take shelter from the rain near the power supply, trees and poles. Try to reduce the height of the body to reduce the risk of direct lightning stroke. Feet should be as close as possible, and the smaller the contact with the ground, the better, so as to reduce the “step voltage”. The best protection places in the wild are caves, ditches, canyons or forest clearing under tall trees. ★ TV, audio and other electrical appliances without lightning protection measures or insufficient lightning protection measures should not be used. Keep away from open doors, windows and metal pipes. Unplug electrical appliances and turn off electrical appliances and natural gas switches. Do not use hair dryer, electric razor, etc. Faucets should not be used. ★ do not touch antenna, water pipe, wire mesh, metal doors and windows, building exterior wall and other live equipment or other similar metal devices. Do not collect clothes on clothesline or wire. Do not engage in the installation of fences, telephones or transmission lines, pipelines or construction steel. Do not dispose of flammable materials contained in open containers. ★ do not or reduce the use of phones and mobile phones. It is not suitable to stay near iron fence, metal clothesline, overhead metal body and railway track. Do not stand on the top of the mountain, on the roof of the building or close to objects with high conductivity. It is not suitable to enter or close to buildings without lightning protection facilities, garages, sheds, temporary sheds, sentry boxes and other low buildings. ★ do not swim or engage in other water sports or activities. It is not suitable to stay in swimming pools, lakes, waterfront, paddy fields and boats. Outdoor ball games are not suitable. It is not suitable to hold an umbrella in an open place. Do not carry hoes, shovel, badminton rackets, fishing rods, golf clubs, etc. on your shoulders. ★ after being charged, you should immediately feel the shock on the skin of others. If you feel the shock, you should immediately stand up when you feel it. ★ do not ride horses, bicycles, motorcycles or tractors. Cars are often excellent lightning protection facilities because of their shielding effect. Even if lightning strikes a car, it won’t hurt people. How should units prevent lightning disasters? ★ the unit shall regularly test the lightning protection facilities by a qualified professional lightning protection detection organization to evaluate whether the lightning protection facilities meet the requirements of national specifications. ★ the unit shall set up a person responsible for preventing lightning disasters to be responsible for lightning protection safety, establish various lightning protection safety work specifications, and establish a regular detection system for various lightning protection facilities. Safety inspection shall be carried out after thunderstorm, and daily maintenance of facilities shall be done well. In case of thunderstorm, check whether the overvoltage protector installed on the power supply and signal line of telephone program-controlled exchange, computer and other electrical equipment is damaged, and replace it in time in case of damage. ★ during the design and construction of lightning protection facilities, the construction unit shall comprehensively consider the characteristics of geology, soil, meteorology, environment, protected objects and the law of lightning activity, and adopt a safe, reliable, technologically advanced, economic and reasonable design and construction method. ★ lightning protection equipment, devices and devices with technology and quality in line with national standards shall be adopted, and non-standard lightning protection products and devices shall be avoided. ★ the lightning protection system shall be redesigned and constructed at the same time for new construction and installation equipment. For example, the lightning protection facilities shall be redesigned and constructed for the re laying of computer network cable and the displacement and elevation of outdoor antenna. ★ in case of lightning disaster, the situation shall be reported to relevant departments in time for timely treatment to avoid being struck by lightning again.
