Introduction

With the social development and technological progress, dangerous chemical species are also increasing, which covers safety regulations has become even more widespread in the country "List of Hazardous Chemicals' existing issued (State Production Safety Supervision Administration Announcement No. 1 of 2003) has more than 3800 kinds of different kinds Class of dangerous chemicals, while the United Nations "on the Recommendations on the Transport of Dangerous Goods Model Regulations" (17th edition) and "GHS Classification and Labelling "for transport of dangerous chemicals, packaging and labels and other relevant requirements, and hazardous chemical species given a clear regulation set.
