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. Dongguan Comprehensive Inspection & Quarantine Technology Center, People's Republic of China Guangdong Entry-Exit Inspection Quarantine Bureau.

Introduction

Chlorine is usually obtained by the electrolytic method, decontaminated after drying, under a certain pressure from the delivery tube of calcium chloride brine (-25 °C ~-35 °C) cooled, condensed into a liquid chlorine. Under normal temperature and pressure chlorine is yellow-green, pungent gas, slightly soluble in water, soluble in disulfide Carbon and carbon tetrachloride. At room temperature, a pressure above 709kPa when chlorine is golden yellow liquid. Mainly for the manufacture of vinyl chloride, epichlorohydrin, chlorine Propylene, chlorinated paraffins, also used as a disinfectant in water treatment processes. Bohai Sea, northwest and southwest region is the main origin of liquid chlorine. Eye Before, the main exporter of imports are Japan, South Korea.

In accordance with the United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations", classified as Class 2.3 toxic chlorine gas, and also has a first Class 5.1 oxidizing substances and Vice-risk Class 8 corrosive substance, UN number 1017. Chlorine is a strong irritant gas, the when inhalation, in contact with the respiratory mucosa surface moisture to produce hydrochloric acid, hypochlorous acid, hypochlorous acid and then decomposed into hydrochloric acid and nascent oxygen to produce Local irritation and corrosion. Chlorine burn, but can support combustion.

In March 2011 the State Council issued the "dangerous chemical safety regulations" [591 State Council Decree] 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.

Inspection of import and export of hazardous chemicals chlorine 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.
