It is said that the suspected cause of this fatal car accident was that violated the route and dangerous driving , resulting in a head-on collision and fire outbreak. A traffic police spokesman said that although the rescue operation has ended, the rescuers who arrived at the scene immediately could not determine the total number of casualties.
Nigeria often reports fatal road accidents, which are usually caused by overload, harsh road conditions and reckless driving.
Accidents of hazardous chemical transport vehicles cannot be ignored.
driving risks are high, and the accident situation is severe. Once an accident occurs,
can instantly swallow fresh life.
Regarding the safety of road transportation of hazardous chemicals,
The following knowledge points must be kept in mind!
. Safety requirements for transport vehicles
Case 1
On the evening of March 29, 2005, a liquid chlorine leakage occurred on the upstream line of the Huaian section of the Beijing-Shanghai Expressway. An tank truck with about 35 tons of liquid chlorine collided with a truck, causing a large-scale leakage of liquid chlorine in the tank truck. 27 people were poisoned and died in surrounding villages and towns. The driver of the tank truck who caused the accident escaped and the truck driver died. The accident caused a large number of villagers in three townships next to the road to poison.
(1) Vehicles transporting hazardous chemicals should not use metal carriages to prevent accidents caused by friction, vibration, etc. If necessary, reliable protective measures should be implemented.
(2) The barrier plate of the transport vehicle should be solid, stable and reliable to ensure that the items will not slide or fall when turning. The loading height of hazardous chemicals shall not exceed the height of the vehicle's blocking plate. The bottom plate of the car should be flat, dense and seamless to avoid causing leakage of liquefaction and chemicals to contact with the transmission shaft and to cause friction and fire.
(3) When transporting vehicles transport dangerous chemicals in mid-summer, they should have sunshade measures or other protective measures, or limited night transportation. Shipping flammable items when wet and should be equipped with oil cloth and other rainproof facilities.
(4) Transport vehicles should configure corresponding fire extinguishing equipment and protective first aid supplies according to the nature of the hazardous chemicals they are equipped for emergency use. Usually, 1211, carbon dioxide or dry powder fire extinguisher can be hung in or near the cab. These fire extinguishing equipment and protective first aid supplies should be inspected regularly. If leakage, damage, deformation or weight reduction, sound shaking of the barrel, etc. are found, they should be repaired or replaced immediately to ensure that they are in good condition at any time.
(5) Transport vehicles should hang special yellow-bottom black-line signal flag with the word "dangerous goods" uniformly stipulated by the public security department to attract the attention of other vehicles with obvious and eye-catching signs. Unrelated personnel are not allowed to take transportation vehicles equipped with flammable, explosive or highly toxic chemicals.
(6) When using a tank truck to transport flammable liquid, there should be an fire arrester and a breathing valve on the top of the tank truck; there should be a device to remove static electricity at the bottom; the exhaust pipe should be equipped with a fireproof (satellite) cover and should be set at the front position (flammable liquid loading and unloading operations are generally at the rear and side of the vehicle); there should be several metal plates in the storage tank to make the tank body have sufficient stiffness and reduce the liquid not shaking or friction during the vehicle driving and produce static electricity; the vehicle's electrical ignition system should ensure good and complete contact to prevent electrical sparks from causing accidents.
(7) When loading and unloading liquefied petroleum gas with tank truck, except that the tank truck storage tank should be inspected, flaw detection, and pressure test comply with relevant requirements, the tank body should be equipped with safety valve , pressure gauge , liquid level meter , overflow valve, emergency shutdown valve, anti-static grounding chain, ignition emergency fire extinguisher and other fire safety facilities that meet safety requirements should be installed on the tank body, and regularly check it to keep it in good condition at any time.
2. Safety requirements for loading and unloading operations
Case 2
At around 8:39 am on September 30, 2019, an explosion occurred in Ningxing Liquefied Storage and Transportation Co., Ltd. in Zhangjiagang Free Trade Zone, Jiangsu Province, causing one death and one injury, and direct economic losses of about 3 million yuan.
(1) The transportation of hazardous chemicals should have fixed loading and unloading operation points or special loading and unloading stations. Dangerous items cannot be mixed with passenger or general freight stations, and should have separate loading and unloading points.
(2) The loading and unloading of hazardous chemicals should be fixed, the vehicle should be fixed, and the location should be fixed. Items of different natures, fire extinguishing methods, and different protection methods shall not be mixed and transported in the same vehicle.
(3) Before loading and unloading hazardous chemicals, the vehicle's compartment should be carefully and thoroughly cleaned to prevent accidents from being mixed with debris and other chemicals.
(4) Hazardous chemicals should be protected from shock and can be placed on the bottom of the car according to the situation. The arrangement of items should be closely and reasonably to prevent shaking or sliding along the way.
(5) When loading and unloading, you should hold it gently to prevent impact, drag and pour. Do not roll with a crowbar and do not press heavily to prevent accidents such as vibration, impact, etc. During loading and unloading, check whether the packaging is firmly sealed and intact. If it is damaged or abnormal, it should not be shipped and should be handled separately.
(6) There should be a dedicated person responsible for the escort during transportation. During transportation, drivers should concentrate on their energy and strictly abide by relevant regulations to prevent sudden braking and sharp turn, so as to avoid accidents caused by impacts, serious displacement of items, etc.
(7) During transportation, you should pay attention to the dynamics of the shipped items at any time. Driving and escorting personnel should strictly prohibit smoking, and irrelevant personnel are not allowed to take it.
3. Safety requirements for driving routes
Case 3
At around 12:00 pm on May 9, 2018, a police officer from the Qingshui Squadron of the Fugu Public Security Traffic Police in Shaanxi Province found that Xu, the driver of a dangerous chemical transport vehicle, was driving without a license while inspecting the Hualianqiao section of Fugu County Fugu Highway.
(1) The transport of hazardous chemicals through the road must be equipped with escort personnel and are under the supervision of escort personnel at any time. They must not be overloaded or overloaded, and must not enter areas where dangerous chemical transport vehicles are prohibited from passing; if they really need to enter the prohibited area, they must report to the local public security department in advance, and the public security department shall specify the driving time and route for them. The transport vehicle must comply with the driving time and route specified by the public security department.
(2) Vehicles that transport dangerous chemicals from a long distance shall not park at will along the way. When it is necessary to use meals, accommodations in the middle or when there is a situation where normal transportation cannot be transported, they shall report to the local public security department, and shall choose an open place or a designated parking lot to park. Transport vehicles shall not leave.
(3) During the high temperature in midsummer, vehicle transportation can be carried out when the temperature is low in the morning and evening.
(4) The "transportation pass" system is implemented for road transportation of hazardous chemicals. Units engaged in the transportation of hazardous chemicals should obtain the qualification certification of the transportation department; when transporting hazardous chemicals, they should fill out the application form for transportation of hazardous chemicals in advance, report to the local public security department for a "transportation pass", and transport them strictly in accordance with the approved date, location and route.
