Safety of Chloromethane Storage and Transportation Specification

1. Introduction

Chloromethane is an important chemical production raw material, widely used in medicine, pesticides, solvents and other fields. However, methyl chloride is flammable, explosive, toxic and other characteristics, which requires high safety during storage and transportation. In order to ensure the safety of methyl chloride in the process of production and use, it is very important to formulate strict storage and transportation regulations.

2. the physical and chemical properties of methyl chloride

methyl chloride is a colorless and transparent liquid with a pungent odor. It is highly volatile, miscible with a variety of organic solvents, and highly flammable and toxic. Methyl chloride is corrosive to metals, especially in the presence of moisture, the corrosion effect is more significant.

3. safety of methyl chloride storage specification

1. Storage facilities: methyl chloride should be stored in a cool, ventilated, dry special warehouse, away from fire, heat and direct sunlight. The floor of the warehouse shall be paved with anti-static materials and set up ventilation facilities.
2. Storage container: Methyl chloride should be stored in a special stainless steel or carbon steel container, avoiding the use of aluminum, copper and other metal containers. The container should be well sealed to prevent leakage.
3. Storage limit: The storage capacity of methyl chloride should be strictly controlled within a safe range to avoid security risks caused by excessive storage.
4. Safety management: professional safety management personnel shall be set up in the warehouse to be responsible for the storage management and safety inspection of methyl chloride. Conduct regular safety training to improve employees' safety awareness.

4. safety of chloromethanes transport specification

1. transport vehicles: chloromethanes should be transported by special dangerous goods transport vehicles, which should comply with relevant national standards and have effective safety facilities such as fire prevention, explosion prevention and leakage prevention.
2. Transport personnel: transport personnel should have professional safety training, have the qualification of dangerous goods transportation, and be familiar with the transportation safety knowledge of methyl chloride.
3. Transport packaging: The transport packaging of methyl chloride should meet national standards, and the packaging materials should have good sealing and pressure resistance to prevent leakage during transportation.
4. Transportation route: The transportation route of methyl chloride should be smooth and smooth, and try to avoid prosperous urban areas and densely populated areas.

5. chloromethane leakage emergency treatment

1. immediately cut off the leakage source, close the valve or take other measures to prevent chloromethane leakage.
2. Use special equipment or absorbing materials to absorb the leaked methyl chloride to avoid its diffusion into the air.
3. Set up a cordon in the security area to prohibit irrelevant personnel from entering the leakage area.
4. If any person is exposed to methyl chloride or has symptoms of poisoning, immediately move it to a safe area and take necessary first aid and protective measures.
5. Report the leakage accident to the local environmental protection and safety supervision department in time, and carry out follow-up treatment according to the requirements of relevant departments.

6. summary

Chloromethane as an important chemical raw material, its safe storage and transportation is very important. In order to ensure the safety of methyl chloride in the process of production and use, it is necessary to strictly abide by the relevant storage and transportation regulations, and strengthen safety management and emergency treatment measures. By taking effective safety measures, the risk of methyl chloride leakage can be reduced and the safety of people's lives and property can be guaranteed.
