The summer was a high time of typhoons, heavy rainfall and heavy rain. Under the influence of cloud systems outside typhoon “white dolphin”, the sea-dwelling areas are highly vulnerable to short-term and intense rainfall and sustained heavy rains, followed by secondary disasters such as flooding in cities, water accumulation, flash floods, landslides and mudslides, which directly threaten the movement of people, the safety of their homes and the safety of their property. The risks of storm disasters are hidden and volatile, and many safety accidents result from minor negligence, scientific knowledge of risk avoidance and the implementation of protection initiatives, which are key defences for the safety of individuals and their families。
Learn about storm risk, read about warning ratings
According to the national standard of gb/t28592-2012 meteorological rainfall grade, heavy rainfall with a 24-hour rainfall of 50 mm and above is a combination of 12-hour rainfall, which is fined to three distinct levels of heavy rain, heavy rainfall, and extraordinary heavy rainfall, which corresponds to a completely different disaster risk intensity. The combination of short-term and sustained rainfall has made it extremely easy to cause water in the area of roads in a short period of time, bringing multiple challenges to the running of cities and the lives of citizens。
Heavy rains associated with typhoons tend to be rapid, intense and prolonged, with the attendant risk of secondary exposure. Low-lying sections of urban areas, underground passages, old neighbourhoods are prone to rain pouring; water accumulations cover the risks of missing well covers, road collapses, etc.; wet and ageing routes are highly vulnerable to electrical accidents; mountains and areas along rivers can also be hit by flash floods, landslides, mudslides, and disasters are devastating and short escape windows. Public risk avoidance can be based on a fourth-level storm warning signal: blue, yellow, orange, red, with an elevated risk level, with close attention to real-time warnings issued by the meteorological services, and rational travel plans。
[preventive home]
We'll clear the area ahead of time
Prior to the storm, residents should take the initiative to conduct home safety checks and to put in place preparedness for shelter. Close doors and windows in time for the onset of the rain, prepare, fix the balcony, the flower basin of the window stand, hanger, etc., for outside miscellaneous items in case of a high-altitude crash. Low-level households, basements and garage owners pre-empt leaks, drains, cleans and secures the discharge of defoliated groceries, equip themselves with sandbags, sheeting, etc., and carry out a comprehensive inspection of household circuits, gas installations, early cut-off of old lines, avoidance of short-circuit rainfall, fires and electrical accidents。
Home-based protection is also not relaxed while rainfall continues. Residents try to stay as far away as possible from the balcony, the window, the outside wall and guard against thunderbolts and crashes. In the event of flooding, wall seepages, electrical intakes, etc., at home, the total power supply, gas valves are shut down at the first moment, the gas valves are quickly evacuated to the safety zone, and no self-inflicted water overhaul equipment is involved to prevent secondary injuries such as electrical shocks and slippages。
[whispering]
You don't have to go out. Stay out of danger
During the storm, citizens were urged to reduce their absence and to adhere to the principle of non-necessity. In view of the exceptional circumstances in which it is necessary to go out of the country, it is necessary to check weather forecasts and road signs in advance, plan the routes rationally, raise safety awareness throughout and avoid all kinds of security hazards。
Water is strictly prohibited on foot from passing through unknown catchments, and there may be fatal risks such as the fall of well covers, the collapse of roads, and the failure of piped electricity. As far as possible, travel is carried out in high terrain and on solid pavements, away from installations such as utility poles, transformers, street lights, billboards, trees, construction barriers, etc., in order to prevent electrical contact and crashes. Low-lying hazardous areas such as riverways, slopes, construction sites and culverts under bridges are avoided, and low-lying areas are avoided. The rain horizons are poor, the walking is slowing down, it is far from rapid water flow, it is less mobile use in the event of thunderstorms, it is far from metal construction and it reduces the risk of lightning strikes。
[driving]
Precautionary speed
The storm's daily sight lines were blocked, the road surfaces were wet, tyre grips were reduced, brakes were longer and the risk of traffic accidents increased significantly. Before driving, drivers are required to check in advance key components such as vehicle lights, rain scratches, brakes and so forth, avoiding water catchment and mountain sections as much as possible, and there are no exceptional circumstances to recommend public transport options。
In the rainy days, close lights, fog lights are activated in a timely manner, long-light lights are banned, speeds are lowered, distance is raised, and no brakes are made or thrusts are made. Water is not allowed when private cars are less than a half of their tires, as determined by the depth of the water in which they are built; the vehicles are put out of fire in the water and are strictly prohibited from setting fire again and the passengers are not allowed to remain in the vehicle. If the vehicle is surrounded by deep water and the door cannot be opened, the window should be broken decisively and the vehicle should be abandoned, evacuated to a high security area and not be greedy of property. The stop was to avoid low-lying sections, trees, billboards and dangerous walls and to prevent vehicle flooding and damage。
[emergency self-help]
Calm down. Science for help
In the face of sudden onsets, calm is the primary prerequisite for self-help, and panic disposal can easily miss the best chance of flight. In the event of a rapid increase in the volume of water and the presence of water in the mountains, do not hesitate to wait and move quickly to the highlands, away from the riverways, steep slopes and low-lying areas, with priority given to ensuring the safety of the person and not to greed for property。
Called 110, 119, 120 distress calls in a timely manner after being trapped, providing accurate information on the location, number of persons trapped and the state of distress and waiting patiently for professional assistance. The population must continue to follow the early warning information on typhoons and rainfall issued by the meteorological and emergency services, adjust travel arrangements in advance and implement anti-silver initiatives to ensure early warning, preparedness and risk avoidance。
[security hints]
Precaution is better than disaster relief
Typhoon was ruthless and safe. The vast majority of heavy rains and secondary typhoons can be avoided by pre-empting and regulating risk avoidance. Home, travel, drive and safety throughout the journey, so as not to lose hope, keep in mind the common sense of risk avoidance and guard from the details。
Wind and rain, peace first. The general public takes the initiative to learn risk avoidance skills, reminds family members and friends to protect themselves, tightens security lines, and works together to secure their own lives and property. (reporter zhou wing)
