Precautions for dangerous goods transportation

2020-06-04

Dangerous chemicals have the dangers of explosion, flammability, poison, corrosion and radioactivity. Once a traffic accident occurs, the harm caused is often greater. Drivers should keep their attention while driving, and need to check more while resting during driving to ensure the safety of the vehicle and the person. We sorted out the relevant points for you from the loading of hazardous chemicals, preparations before going to the road, and safe driving.

Notes on loading hazardous chemicals

1. Dangerous chemical transportation enterprises, vehicles, escorts, and loaders must obtain corresponding qualifications.

2. The loading medium is consistent with the tank spraying medium and the vehicle road transport certificate.

3. The loading of dangerous chemicals is even and balanced, and the whole is fixed, so that one vehicle and one cargo can be mixed. Different dangerous chemicals cannot be mixed and overloaded.

4. After loading the hazardous chemicals, the name, shape, quantity, disposal method, and contact information of the hazardous chemicals shall be recorded in writing and carried along with the vehicle.

5. After loading the liquid hazardous chemical tanker, the emergency shut-off valve should be closed to ensure no damage or leakage.

Precautions for dangerous goods transportation

Inspection work before driving

1. The Bhachu acid tanker trailer number plate is installed intact, the safety inspection signs and insurance signs are placed correctly, the driving license, road transportation license, and road transportation permit for highly toxic chemicals are complete and valid and can be carried with the vehicle.

2. Safety devices such as vehicle marking lights, signs, reflective signs, side rear protective devices, and fire extinguishers are well configured, and satellite positioning devices are working properly.

3. The vehicle braking, lighting, and turn signal safety systems meet the operating requirements, the tire specifications are qualified, the wear is normal, and the retreaded tires are not used.

4. The emergency cut-off device for the transportation of liquid hazardous chemicals tankers is in good condition and is in a closed state.

Precautions for dangerous goods transportation

Safe driving

1. Choose a reasonable driving route with good traffic conditions, stay away from towns and residential areas, and do not enter the prohibited areas of dangerous goods transport vehicles. Bhachu Vehicles transporting highly toxic chemicals must be driven according to the time and route approved by the public security organs, and may not be changed at will.

2. Maintain a reasonable driving distance from the vehicle in front, and increase the separation distance in case of rain, fog, snow and other bad weather.

3. Drivers should keep their attention. They should stop and rest every 2 hours or so, and check the technical status of the vehicle in time to ensure that the emergency shut-off valve is closed.

4. It is not allowed to change lanes arbitrarily while driving. Highway traffic must be driven in the specified lanes.

Precautions for sulfuric acid tank transportation

Anti-corrosion measures

In addition to the selection of corrosion-resistant materials and reasonable structural design, the anti-corrosion of sulfuric acid tanks can also take some other measures, such as reducing the flow rate of sulfuric acid, electrochemical protection, passivation, using cover layer protection and strengthening and improving the operation management of storage tanks.

1)Strengthen management.

Concentrated sulfuric acid has strong hygroscopicity. When carbon steel sulfuric acid storage tanks are often filled with concentrated sulfuric acid, the corrosion is very weak, but if they are often emptied (such as frequent parking, not used for a long time after emptying), the thin attached to the inner wall of carbon steel tank A thin layer of concentrated sulfuric acid will quickly absorb water in the air and become thinner, and the corrosion of carbon steel becomes so severe that it causes perforation. It is also necessary to strengthen the management of the venting of concentrated carbon sulphate steel tanks, shorten the venting time, or take other management measures such as dehumidification.

2) Electrochemical protection.

Mainly the anode protection method. After the anode protection is applied, the corrosion rate of carbon steel in sulfuric acid is greatly reduced;

3) Use of thermal insulation coatings.

Since the corrosiveness of sulfuric acid increases with the increase of temperature, in order to avoid the temperature of Bhachu sulfuric acid in the tank due to sunlight, the outer wall of the tank should be sprayed with a light-colored (usually white) topcoat, or use Very popular heat-shielding paint on the surface;
