Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules.

This standard is proposed and managed by the National Certification and Accreditation Administration Committee.

This standard was drafted. People's Republic of China Anhui Entry-Exit Inspection and Quarantine Tianjin People's Republic of China Bureau, People's Republic of China Shanghai Entry-Exit Inspection and Quarantine Bureau.

Introduction

Acrylonitrile is usually colorless liquid with a pungent odor, slightly soluble in water, benzene, acetone, methanol and other organic solvents miscible. Acrylonitrile Mainly for the manufacture of polyacrylonitrile, nitrile rubber, dyes, synthetic resins, pharmaceuticals and the like. The main origin of acrylonitrile Jilin, Shanghai, mountain East, Anhui and other provinces, the main importing countries the United States and South Korea.

United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (UNRTDG) acrylonitrile main risk classified as a Category 3 flammable Liquid, secondary hazard classified as Class 6.1 toxic substances, the United Nations No. 1093. Acrylonitrile in the transport, storage, adding a certain amount to be the polymerization inhibitor (eg. hydroxyanisole), suppressing self-polymerization of acrylonitrile. Acrylonitrile is highly flammable vapor and air can form explosive mixtures, in case of fire, heat can lead to a fire or explosion, and emit toxic gases. Acrylonitrile through the respiratory tract, gastrointestinal tract and intact skin into the body.

Precipitation of cyanide in the body, respiratory enzyme inhibition; paralysis of the respiratory center has a direct effect. Severe poisoning grand mal epilepsy-like convulsions, coma, pulmonary Edema.

In March 2011 the State Council issued the "Dangerous Chemicals Regulations"] [State Council Decree 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 acrylonitrile Warning. Use of this standard should have the relevant inspection or testing work experience and relevant qualifications. This standard does not point out all Possible security issues. Users are responsible for the use of appropriate safety and health practices and to ensure compliance with the conditions relevant national regulations.

1 Scope

This standard provides for the import and export of acrylonitrile and packaging requirements, testing, qualified judgment and disposition.
