How to prevent rainstorm

How to Prevent Rainstorms and Flood Disasters (1) Adhere to the idea of safety first, and managers and team leaders must set an example and implement it in the specific work of each staff member.

(2) Ensure the safety production plan, implement the production responsibility, and ensure the implementation of a number of specific measures to prevent disastrous weather.

(3) Combine regular and seasonal inspections to prevent all kinds of accidents, carefully analyze the causes of hidden dangers and symptoms of accidents, and propose and implement improvement plans.

(4) The weather forecast system shall be implemented. Every day, a special person is responsible for filling in the forecast content of the local meteorological station, and early warning reminders should be used in case of heavy rain.

(5) All mechanical equipment and electrical boxes shall be checked for electricity safety, and some equipment shall be protected against flood.

(6) Overhead cables and passing cables should be carefully inspected to ensure that they have the ability to resist wind and heavy rain, so as to prevent personal safety and property from being endangered.

(7) Do a good job of disaster relief in dormitories, warehouses and offices, and take timely repair and preventive measures for houses with hidden dangers. Dangerous houses with hidden dangers need to be transferred and resettled immediately.

(8) Necessary preventive measures should be taken for the completed box culvert joint manhole cover, and the box culvert foundation pit under construction should be equipped with enough water pumps to prepare for storm drainage.

4. Rescue and evacuation According to the principle of "saving people is more important than disaster relief" and the operating rules of enterprise disaster prevention drills, the first step is to call an ambulance to rescue employees trapped by disasters, and at the same time evacuate personnel and materials to safe areas in an orderly manner.

Emergency measures for possible collapse of buildings and structures, casualties and equipment damage after heavy rains and destructive floods; It is very likely that secondary disasters such as fire, explosion and a large number of dangerous chemicals will occur. Flood emergency procedures are mainly applicable to the prevention of possible accidents and emergency response after accidents when there are flood records or possible floods in the area where the enterprise is located. According to the different flood intensities that different enterprises can bear, this scheme takes into account the flood emergency measures issued by the Meteorological Center, and formulates specific scheme contents. This procedure should be closely related to the measures to be taken issued by the local emergency rescue department and meteorological service center. The accident prevention measures in the scheme should include the identification of flood warning signals (rainstorm, thunderstorm, melting of ice and snow in winter, etc.). ) in order to take necessary preventive measures before the flood comes or before the meteorological center issues a flood warning. In the emergency measures for accidents, special actions that need to be taken in flood emergency should be listed, such as the division of areas where sandbags need to be filled, the acquisition and replenishment of sandbags, the movement of important equipment, the recording of buildings, the confirmation of evacuation routes, and the anti-skid of automobiles, especially tankers.

1. Disaster Warning When the Meteorological Observatory issues emergency warnings such as rainstorm, rainstorm or typhoon, all personnel of the enterprise emergency plan leading group enter an emergency state. Team members should command all construction teams to make good preparations for flood control, such as preparing sandbags, strengthening temporary building doors and windows, and warehousing measures for various mechanical equipment. At the same time, the team leader should report the flood control situation to the company leaders and obey the unified dispatching command.

2. In case of typhoon or flood, members of the emergency plan leading group should immediately go to the scene to organize rescue work. Construction personnel are required to cut off all power supplies and evacuate personnel and materials to safe areas in an orderly manner. If casualties are found, rescue should be organized in time and reported to the superior leader in time.

Characteristics of rainstorm and flood in China;

Characteristics of rainstorm and flood in China. Geographical distribution characteristics of rainstorm and flood in China Most of China is located in the mid-latitude area, and large-scale rainstorm is mainly formed by two types of weather systems: one is the low-value system in the westerly belt, including cyclones, shear lines, eddies, troughs and fronts, which affect most of the country. This kind of rainstorm generally covers a wide range, lasts for a long time and has a large amount of precipitation. It often forms a combination of rainstorm and flood in a large basin, which can cause a wide range of serious floods. The other is a low-latitude tropical weather system, including tropical cyclones and easterly waves. , more common in South China and southeast coastal areas. Although this kind of rainstorm lasts for a short time, it is often strong and can also cause serious floods. In particular, the above-mentioned systems are weakened into low-pressure or peripheral cloud systems, which can often go deep into the central or northern regions of China, causing large-scale heavy precipitation and serious floods. It can be seen from the average distribution map of annual rainstorm days in China that its characteristics are also more in the southeast and less in the northwest; There are many coastal areas and few inland areas; There are many windward slopes and few leeward slopes. The coastal areas of Guangdong, northeastern Guangxi, northeastern Hunan and Jiangxi, and western Sichuan Basin are prone to heavy rains and floods.

2. Seasonal distribution characteristics of floods The season of floods is closely related to the rainy season (i.e. seasonal advance and retreat of monsoon rain belt), precipitation concentration period and tropical cyclone activity.
