This article mainly describes what protective equipment should be equipped during the transportation of dangerous goods and what emergency measures should be taken after encountering an accident. I hope that all industry partners can share their experience and jointly create a safe logistics environment for dangerous goods.
What are dangerous goods?
According to the provisions of the national standard GB6944-86 "Classification and Product Name Number of Dangerous Goods", any explosive, flammable, corrosive and other properties that are likely to cause personal injury or property damage during transportation, storage and storage require special protection. The goods are all dangerous goods, that is, dangerous goods.
The road transport of dangerous goods must have transport equipment and loading and unloading equipment to ensure safety, as well as operation management personnel, drivers and escorts who are familiar with the performance of dangerous goods, so as to ensure the safety of dangerous goods transport.
| serial number | category | content | Precautions |
| 1 | Motor vehicle cargo box | It should be a wooden base to avoid sparks. | If the iron bottom plate is used, the corresponding liner should be used for protection. |
| 1. Motor vehicle exhaust pipes must have heat insulation and spark extinguishing devices. | |||
| 2. According to the nature of the dangerous goods to be loaded, the corresponding fire-fighting equipment and binding, waterproof, and loss-proof appliances should be equipped. | |||
| 2 | The tank (tank) car tank (tank) body material must be compatible with the nature of the loaded goods | 1. Aluminum tank should be used for nitric acid, glass fiber reinforced plastic and stainless steel should be used for waste nitric acid. Equipped with double gates, anti-wave boards, sunshades and other safety devices as required. | |
| 2. Vehicles carrying containers, large gas cylinders and movable tanks (tanks) must have effective strong equipment and corresponding wooden stoppers. | |||
| 3 | Special transport vehicles and equipment for transporting radioisotopes must comply with the relevant regulations of the health and epidemic prevention, public security and other departments. | Carry out regular inspections of radioactive pollution on vehicles, equipment, transport tools, and protective equipment. When the pollution radiation intensity exceeds the standard, they must be cleaned and disinfected before they can continue to be used. | |
| 4 | Various loading and unloading machinery used require sufficient safety factor | General design requirements exceed one-third of the load capacity | For example, a crane and crane with a rated load of 5 tons should be able to reach a lifting capacity of 6 to 7 tons. |
| Shipping machinery must have explosion-proof devices to eliminate sparks. It is forbidden to use tools that are prone to friction and generate sparks, and the tools used must not be stuck with pollutants that conflict with the loaded goods. |
During transportation, ifLeakage phenomenon, the following measures should be taken:
| serial number | category |
measure |
| 1 |
Explosives | Quickly transfer to a safe place to repair or replace the package, moisten the leaked items with water in time, sprinkle some soft materials such as sawdust or cotton wool, and gently collect them. |
| 2 | compressed gas or volatile liquid | Open the car door, garage door, and move to a ventilated place. Leakage of liquid ammonia can be immersed in water, and other highly toxic gases should be immersed in lime water. |
| 3 |
Self-igniting or water-burning products | After the yellow phosphorus is spilled, it must be immersed in water quickly, and metal sodium, potassium, etc. must be immersed in an iron drum filled with kerosene or anhydrous liquid paraffin. |
| 4 | Flammable | Point the leak up. Cover the spilled matter with dry yellow sand and dry soil and clean up. |
| 5 |
Poison | Quickly cover it with sand and evacuate people, and ask the health and epidemic prevention department to assist in handling. |
| 6 | Corrosion | Cover with sand, rinse with clean water after cleaning. |
| 7 |
Radiation | Quickly stay away from the radioactive source, protect the site, and ask the health and epidemic prevention department to guide and deal with it. |
Case Studies
A. Introduction to the cause of the accident:
A heavy-duty van truck carrying "toluene-2,4-diisocyanate" (hereinafter referred to as TDI) in the companyHeavy load in transitFrom east to west through the ** District ** Road section,Due to the discovery of an abnormal situation, the driver applies emergency braking, a rear car traveling in the same direction hit the right rear rear of the car due to improper distance between the cars and insufficient measures to rear-end the car.
B. Situation Analysis and Handling of Accidents
After the accident, the driver turned off the engine, pulled the brakes, and turned on the double-jump lights. The accompanying escort immediately got out of the car to check the scene and found that liquid overflowed from the rear of the box. Since TDI is a poisonous and dangerous chemical, the driver wears a gas mask, takes the adsorption surface equipped with the vehicle to fill the leakage point, opens the door to observe the leakage situation, takes off the fire extinguisher on the vehicle and places it next to the leakage point to prevent material Fire caused by high temperature open flame. At the same time, the escort went to the upwind side of the rear car, called 110 with a mobile phone and reported the accident to the dispatch center, requesting rescue. And asked the passing social vehicles to arrange for the wounded to be sent to the hospital for treatment.
110 police cars and fire engines arrived at the scene of the accident one after another. The driver told the traffic police about the accident and submitted the MSDS of the transported product to the firefighters. At the same time, the rescue team of the company's emergency center arrived, entered the scene wearing full equipment, set up a cordon, carried out on-site disposal, blocked the sewer, contained the leak at the leak point, wrapped the damaged material barrel with absorbent cotton and removed it. (Assist in diverting vehicles). Finally, the traffic police on-site investigation and evidence collection was completed, and the scene was cleaned up and removed.
C. Contingency outcomes following an accident
TDI belongs to Class 6.1 toxic and dangerous chemicals, has a strong irritating smell, is accumulative and latent in the human body, and has a strong irritating effect on the skin, eyes and respiratory tract. Inhalation of high-concentration toluene diisocyanate vapor can cause bronchitis , bronchopneumonia and pulmonary edema, contact of liquid with skin can cause dermatitis. The contact of the liquid with the eyes can cause serious irritation, and if it is not treated in time, it may cause permanent damage. The professional handling of the accident by the driver and the escort minimized the possible dangerous properties.
Tips for safe transportation
It is hoped that major companies in the same industry will improve the emergency response capabilities for dangerous goods transportation, and fully control the spread of danger in a timely, rapid and efficient manner to ensure the safety of corporate property and people's lives.
I hope that while learning about the equipment and facilities that dangerous goods vehicles should have, you can strengthen your practical ability to deal with dangerous chemical leakage, and improve the professionalism of enterprises in the transportation and management of dangerous chemicals. Let's protect the safety of Shanghai port together.
