Precautions for cold wave attack Due to low temperature, some domestic flights of China Southern Airlines were temporarily cancelled.

This winter is particularly cold. Recently, the temperature has dropped sharply. China cold wave warning has reached orange. Affected by the cold weather, some domestic flights of China Southern Airlines were temporarily cancelled. In addition, there will be many things to pay attention to when the cold wave strikes. It's better for everyone to go out less. What safety matters should be paid attention to and should be understood in detail.

What are the safety problems in cold weather? First, we should pay attention to traffic safety. Cold wave and strong wind are superimposed, and the weather is bad. When going out, pay close attention to the weather changes, add clothes in time to keep out the cold and keep warm. When traveling by car, you should check the vehicle equipment in advance, pay attention to whether the road is slippery and icy, obey the traffic rules, keep the distance between cars, and slow down.

The second is to pay attention to production safety. Under the condition of low temperature weather, all production and operation enterprises and units should strengthen the inspection and maintenance of facilities and equipment, especially the equipment susceptible to low temperature, and take anti-freezing measures to investigate the potential safety hazards in advance to avoid machine failures caused by low temperature and safety production accidents. Outdoor construction units should pay attention to the hidden dangers caused by windy and cold weather, do a good job in strengthening facilities and keeping workers safe and warm, and ensure that all safety protection measures are put in place.

Third, we should pay attention to the safety of electricity and gas. In low temperature weather, household electricity consumption has surged, so the power supply and gas supply department should strengthen the inspection of power and gas lines to eliminate potential safety hazards in time. Residents should also standardize the use of high-power electrical appliances, pay attention to replacing aging lines, do not connect wires privately, and do not charge electric vehicles in corridors or indoors. When cooking, heating and bathing with natural gas, be sure to keep ventilation, and always check whether the pipes and valves are safe and leak-free, so as to avoid carbon monoxide poisoning or fire hazards.

Fourth, do a good job in forest fire prevention. In the next few days, because there is relatively little rain and snow in our province and the weather is relatively dry, all localities and relevant departments should pay close attention to the investigation and rectification of fire hazards, strengthen the management of wild fire use, prevent fire sources from entering forest areas, establish and improve the responsibility system for safety and fire prevention, and strictly guard against forest fires.

What health hazards will the cold wave bring to people? How should the public be protected? Short-term sharp changes in temperature will cause stress response of human body. Cold weather can cause or aggravate many cardiovascular and cerebrovascular diseases such as hypertension, coronary heart disease and stroke, as well as upper respiratory tract infection (common cold and flu), pneumonia, asthma (especially childhood asthma) and COPD (chronic obstructive pulmonary disease).

The temporary cancellation of some domestic flights of China Southern Airlines was affected by low temperature and cold wave weather, and there were strong winds or freezing rain and snow weather in many parts of the country. On the 7th, the reporter learned from China Southern Airlines that China Southern Airlines has launched flight operation guarantee plans in bad weather in many places to ensure the safety of flight operation. As of press time, due to the freezing rain, China Southern canceled Guiyang 2 1 flight and Changsha 13 flight, and the flight operation was generally stable.

Despite the cold weather, the front-line staff of China Southern Airlines stuck to their posts and completed various flight support work. In the low temperature environment, the aircraft surface is prone to produce ice and snow frost, and the ice layer may cause changes in the aerodynamic shape of the aircraft, difficulties in operating the flight control surface, inaccurate indication of cockpit instruments, damage to engine blades and other problems that affect flight safety. In order to do a good job in deicing and ensure the safe and orderly departure of flights, China Southern Airlines dispatched deicing vehicles at several airports for deicing operations.

On June 6th, 65438/KLOC-0, Beijing launched a Class IV emergency response to major meteorological disasters. Daxing Airport launched the first yellow gale warning in the New Year, and all front-line units of China Southern Airlines Beijing Branch sent additional support personnel in advance to strengthen on-site flight support supervision, focusing on explaining and prompting the risks of low temperature and wind shear. Affected by the severe cold weather and the epidemic situation in Hebei, the normal rate of early departure flights is 100%, and the normal rate of all-day flights is 95.45%.

In addition, China Southern Airlines starts at Harbin Airport at 6: 00 every morning, and all six de-icing vehicles are dispatched to carry out de-icing operations. 654381October 7th, China Southern Airlines used four deicing vehicles and 1 1 deicer to deice the aircraft at Urumqi Airport. During deicing, the crew should deice the fuselage, wing, tail and engine in turn according to the relevant work instructions and APS operation instructions to ensure the best use effect of deicing and anti-icing liquid.
