Dangerous goods transportation loading and unloading link
1. Flammable liquid
There shall be no residues such as oxidants, natural objects, strong alkalis, etc. in the compartment.
The flammable liquid contained in the steel drum shall not be rolled from a high place to unload the truck. When unloading the truck from the top or rolling operation, measures should be taken to prevent sparks, and there must be people around to prevent damage caused by the impact of the steel drum.
When steel packaging is loaded in multiple layers, suitable liners must be used between the layers and they should be tied firmly.
For flammable liquids with low boiling points or easily polymerized, if the packaging container is found to contain swelling (drum barrels), the consignor can change the packaging before continuing loading.
When loading and unloading tank (tank) vehicles, the hand brake should be tightened, the wheels should be fixed, the engine should be turned off, the main power supply device should be cut off, and the static electricity removal device should be connected. The operator must not leave the post. The night loading and unloading operations should use explosion-proof lighting equipment.
The floor of the transport vehicle compartment must be flat and intact. When shipping with iron bottom, protective measures such as plywood, plywood, rubber board, etc. should be taken, and there must be no acid, alkali, oxidant and other residues. When loading and unloading, operators are not allowed to wear fire or shoes with nails and work clothes that are prone to static electricity. Do not drop, roll, and prevent friction, impact and severe vibration during operation. It is strictly forbidden to touch open flames, high temperature, and use iron tools.
Items that can be stacked must be placed according to the storage and transportation icons on the package, and the part of the tallest item that exceeds the fence must be less than one-third of the package. After loading the vehicle, it should be covered tightly with tarpaulin and tied firmly. The total height of the stack of vans should not exceed 1.5 meters. When using mechanical loading and unloading operations, the load should be reduced by 2% according to the specified load. Avoid exposure to sunlight, rain, high temperature and open flames during transportation. When there is a thunderstorm on the way, stay away from trees, electric poles or large buildings to prevent lightning strikes. When transporting in a group, a special person should be designated to be responsible for unified guidance, and a safe distance between vehicles should be maintained. When parking a vehicle, you should choose the parking place strictly, away from high-voltage electricity, fire and high temperature and other places, and separate it from other vehicles and leave it under special supervision.
3. Compressed gas and liquefied gas
There shall be no grease contaminants and strong acid residues in the cabin.
Tighten the bottle cap when loading the car, and pay attention to protect the valve of the gas cylinder to prevent collision; the personnel under the car must wait for the personnel on the car to put the bottle in place before continuing to bottle the car. Two people are not allowed to bottle at the same time individually in the same compartment. Except for gas cylinders that allow vertical installation (such as civil liquefied petroleum gas, etc.), the gas cylinders on the vehicle should be placed horizontally, load balanced, and properly fixed to prevent rolling. The valve shall face one side, and the uppermost cylinder shall not exceed the height of the carriage rail.
During loading and unloading operations, do not aim the valve at the person, pay attention to prevent the bottle safety cap from falling off, the gas cylinder should be turned upright, and it is not allowed to take off the bottle or transfer it. The gas cylinder must be secure immediately.
When transporting large gas cylinders (with a weight of more than 0.5 tons) or composing a gas cylinder, the bottle and the bottle, the pallet and the pallet must be filled with wooden corks, and the bottle mouth of the pallet should be facing the direction of the traveling vehicle. On the right, there must be a fixed support at the gap between the rear baffle and the gas cylinder, and a rope tensioner must be tightened to prevent the cylinder from rolling, and heavy bottles are not allowed to be loaded in multiple layers.
Four, corrosive products
Before operation, wear corrosion-resistant protective equipment. For volatile and toxic vapors or fumes, a gas mask should be provided, and the packaging (including the seal) should be carefully checked for good condition and leakage is strictly prohibited. It is especially necessary to prevent the outer packaging from breaking and peeling off the bottom. Liquid corrosive products are not allowed to be carried, carried on their backs, avoid rolling, rubbing, and fragile containers and packaging must not be stacked. Oxidizing items must not be exposed to high temperature and open flames. When there is a thunderstorm on the way, stay away from trees, electric poles or large buildings to prevent lightning strikes. When transporting in a group, a special person should be designated to be responsible for unified command, and a safe distance should be maintained between vehicles. When parking a vehicle, you should choose the parking place strictly, away from high-voltage power supply, fire and high temperature and other places, and separate it from other vehicles and leave it under special supervision.

Liquid corrosive products are not allowed to be carried, carried on their backs, avoid rolling, rubbing, and fragile containers and packaging must not be stacked. Oxidizing items must not be in contact with combustibles and reducing agents. Organic corrosive products are strictly prohibited from contact with open flames, high temperature or oxidants. Alkaline and acid corrosion products must not be mixed. Inorganic acid corrosion products are not allowed to be mixed with organic acid corrosion products.
5. Flammable solids, spontaneously combustible items and flammable items when wet
During loading and unloading operations, do not fall, roll, throw or throw.
Before loading, no acid, grease and oxidant residues should be left in the compartment.
The loading and unloading operation site must be far away from fire and heat sources, and operators are not allowed to wear fire and shoes with nails.
It is strictly prohibited to use iron tools that are prone to sparks, and the loading and unloading machinery should be equipped with anti-spark devices.
It is strictly forbidden to transport wet and flammable items without rain and snow protection equipment in rain and snow.
Six, oxidants and organic peroxides
Before loading the vehicle, there must be no acid or soft powdery combustible residues in the vehicle compartment. When loading and unloading, please keep away from fire and heat sources.
Do not drop, drag, rub, or roll violently during loading and unloading operations, and do not use iron tools.
Strong oxidizers packed in steel drums must not be stacked. When stacking is necessary, safety liners must be provided between the containers.
The wheels of trolleys and forklifts should be made of non-metallic materials such as rubber. The loading and unloading tools must not be left or contaminated with impurities. The pallets and trolleys should be dedicated as much as possible. The loading and unloading tools should be equipped with devices to prevent sparks.
During transportation, the speed should not be too fast, and overtaking is not allowed.
