In the rainy season, the thunder and lightning are not willing to show weakness.

On the evening of June 24, heavy rain fell suddenly in many places in Zhejiang. It was dark and dark, lightning and thunder in a short period of time, and the rain fell down, accompanied by strong winds. Accompanied by dark clouds and lightning, many passers-by were forced to become "rainmen". Many roads in Hangzhou City had serious water accumulation and many vehicles were flooded. The heavy rain dragged us into the rainy season. So, during the rainy season, what should we pay attention to when lightning strikes? How should enterprises prevent lightning disasters?

Status: Sustained rain disrupts Hangcheng Life Metro's entrance to move sandbags to block rain

At 12 noon on the 27th, the reporter saw at the entrance and exit of Metro City Station D that rainwater followed the steps of the station hall into the passageway of entrance D. At the bottom of the stairs, a layer of camouflage sandbags has been laid. The sandbags are about two layers, not high; further in, the red non-slip carpet goes straight into the station hall, which is very eye-catching.

Hangzhou Metro Group said that in response to heavy rain or flood season, the subway has three emergency plans to deal with, and there are three physical defense lines. First of all, on the side of the walking steps at the entrance and exit, there are three steps higher than the surrounding municipal sidewalk, about 45 cm, and on the remaining three sides, there are 80 cm high retaining walls. Secondly, each station is equipped with a 35 cm high flood gate, which is directly inserted into the card slot when it encounters heavy rainfall, so that the entrance and exit as a whole is 80 cm higher than the surrounding municipal sidewalk. At the same time, sandbags are also provided at each station to stack the entrance and exit. Finally, if backfilling or seepage occurs, the station also has sump and sump. Each sump is provided with two pumps, one for normal use and the other for standby. The rainwater entering from the entrance and exit can pass through The drainage facility pumps water to the urban drainage system.

During the rainy season, what should we pay attention to when lightning strikes?

The rain was so fierce that the thunder and lightning were naturally not to be outdone. So, what should we pay attention to when lightning strikes?

★ Stay indoors and close doors and windows. When it is impossible to hide in a building with lightning protection facilities in the wild, remove metal objects such as watches and glasses, and never avoid rain near the power supply, trees, and poles. Try to reduce the height of the body to reduce the risk of direct lightning strikes. Keep your feet as close as possible. The smaller the contact with the ground, the better to reduce the "step voltage". The best shelters in the wild are caves, ditches, canyons, or forest clearings under tall trees.

★ It is not advisable to use televisions, stereos and other electrical appliances without lightning protection measures or insufficient lightning protection measures. Keep away from open doors, windows and metal pipes. Unplug electrical appliances and turn off electrical appliances and natural gas. Never use hair dryer, electric shaver, etc. The faucet should not be used.

★ Do not touch live equipment such as antennas, water pipes, barbed wire, metal doors and windows, building exterior walls or other similar metal devices. Do not collect clothes on the clothesline or wire. Do not engage in installation work such as fences, telephones or power lines, pipes, or construction steel. Never handle flammable materials contained in open containers.

★ Do not use or reduce the use of phones and mobile phones. Do not stay near iron fences, metal clotheslines, overhead metal bodies, and rails. Do not stand on the top of a mountain, on the top of a building, or near objects of high electrical conductivity. It is not advisable to enter or close to buildings without lightning protection facilities, garages, carports, temporary sheds, sentry boxes and other low-rise buildings.

★ Do not swim or engage in other water sports or activities. It is not advisable to stay in swimming pools, lakes, beaches, paddy fields, etc. and boats. Not suitable for outdoor ball sports. Umbrellas should not be used in open areas. Should not carry hoe, shovel, badminton racket, fishing rod, golf club, etc. on your shoulders.

★ When you feel the body is charged, such as the hair is raised, or the skin is trembling significantly, to understand that you may be subjected to electric shock, you should immediately fall to the ground, and call someone for help after the lightning.

★ It is not suitable to ride horses, bikes, motorcycles and tent tractors. Cars are often excellent lightning protection facilities because of their shielding effect. Even if the lightning strikes the car, it will not hurt people.

How should the unit prevent lightning disasters?

★ The unit should regularly inspect the lightning protection facilities by a qualified professional lightning protection inspection agency to assess whether the lightning protection facilities meet the requirements of national regulations.

★ The unit shall establish a person responsible for lightning disaster prevention to be responsible for lightning protection safety work, establish various lightning protection safety work standards, and establish regular detection systems for various lightning protection facilities. After thunderstorms, safety inspections should be carried out and daily maintenance of the facilities should be done. After the thunderstorm passes, you should check whether the overvoltage protector installed on the power supply and signal line of electrical equipment such as telephone program-controlled switches, computers, etc. is damaged, and replace it in time if damage is found.

★ When designing and constructing lightning protection facilities, the construction unit should consider comprehensively according to factors such as geology, soil, meteorology, environment, characteristics of protected objects and lightning activity laws, etc., and adopt safe and reliable, advanced technology, economic and reasonable design and construction methods .

★ Lightning protection equipment, devices and equipment that meet the national standards in technology and quality should be used, and non-standard lightning protection products and devices should be avoided.

★ Newly added construction and newly added equipment should simultaneously redesign and construct the lightning protection system. For example, the laying of computer network cables, the displacement and heightening of outdoor antennas should redesign and construct lightning protection facilities.

★ When a lightning disaster occurs, you should report the situation to the relevant departments in time, so as to deal with it in time and avoid being struck by lightning again.
