The safety storage and transportation specification
of tetrachloroethane
1. Introduction

tetrachloroethane is a commonly used chemical production raw material, widely used in pesticides, refrigerants, solvents and other fields. However, due to its toxicity and flammability, it is necessary to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safety storage and transportation specifications for tetrachloroethane.

2. the nature of tetrachloroethane

tetrachloroethane is a colorless transparent liquid with a pungent odor. It has an irritating effect on the eyes, skin and respiratory tract, and can cause toxic pneumonia and pulmonary edema. Tetrachloroethane is also flammable and can cause combustion and explosion when exposed to open flame, high heat or oxidant.

3. tetrachloroethane storage specification

1. The storage place should choose a cool, ventilated and dry place, away from fire and heat sources. The storage temperature should not exceed 30 ℃ and the relative humidity should not exceed 80%.
2. The storage container shall be a special container with good sealing performance to avoid leakage and volatilization. The container shall be inspected and maintained regularly to ensure that it is in good condition.
3. The storage site should be equipped with leakage emergency treatment equipment, such as sand, absorbent cotton, etc., to deal with possible leakage accidents.
4. The storage area should be set up with obvious safety warning signs, no smoking and open fire.

4. tetrachloroethane transport specifications

1. Transport vehicles should comply with relevant standards, with explosion-proof, fire prevention, anti-static and other safety performance. During transportation, it should be kept stable to avoid severe vibration and collision.
2. Before transportation, check the sealing performance of the container to ensure that there is no leakage. During transportation, the container and pipeline shall be checked regularly for air leakage, and the problems found shall be handled in time.
3. During transportation, it should be away from fire and heat sources, and it is forbidden to mix with oxidants, acids, alkali metals and other items.
4. During transportation, corresponding emergency treatment equipment and personnel shall be equipped to deal with possible leakage accidents.

5. leakage emergency treatment

1. In case of tetrachloroethane leakage accident, the emergency treatment plan shall be started immediately and professionals shall be organized to deal with it.
2. The fire source should be cut off in the leakage area, and the personnel in the leakage pollution area should be quickly evacuated to the safety area, isolated and strictly restricted. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and protective clothing. Cut off leakage sources as much as possible to prevent them from flowing into restricted spaces such as sewers and flood discharge ditches.
3. When a small amount of leakage, use activated carbon or other inert materials to absorb. In case of a large amount of leakage, build a dam or dig a pit to accommodate it; cover it with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

6. conclusion

tetrachloroethane as a commonly used raw material for chemical production, its safety and standardization of storage and transportation are very important. During storage and transportation, the relevant safety regulations should be strictly observed to ensure the safety of personnel and the environment. At the same time, the construction of emergency handling capacity should be strengthened to deal with possible leakage accidents.
