Introduction

Methyl chloride, commonly known as methyl chloride. Methyl chloride is widely used in industrial production, mainly for the production of methyl chlorosilane, tetramethyl lead, methylcellulose Cellulose. For the production of a small amount of quaternary ammonium compounds, pesticides, solvents and the like made in butyl rubber production. A major producer of methyl chloride for China Jiangsu, Shandong and other provinces and cities.

United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" to a chloride classified as dangerous goods of Class 2.1, UN Code 1063. Methyl chloride is a colorless gas, compressed to form a colorless liquid with a sweet taste and smell of ether. Flammable, toxic. However, having a chloride There are some health and environmental hazards, serious damage to the central nervous system, it can also damage the liver and kidneys. Main features. acute poisoning, has a head Pain, dizziness, nausea, vomiting, blurred vision, symptoms. Severe poisoning can occur restlessness, convulsions, tremors, visual disturbances, coma and other symptoms. skin Skin contact may result in rapid evaporation of methyl chloride surface caused frostbite, and a certain amount of air and water pollution.

In March 2011 the State Council issued the "dangerous chemical safety regulations" (State Council Decree No. 591) provides for inspection and quarantine departments Responsible for the import and export of hazardous chemicals and their packaging implementation of the inspection. To ensure the effective implementation of the relevant inspection and quarantine operations, standardize import and export Dangerous chemicals and packaging inspection and supervision work, the development of this standard.

Import and export of dangerous chemicals inspection of chloromethane Warning. Use of this standard should have the relevant inspection or testing work experience and relevant qualifications. This standard does not indicate all possible security issues. Users are responsible for the use of appropriate safety and health practices and to ensure compliance with relevant national regulations condition.
