Abstract: In order to explore accident characteristics and identify relevant risk factors, this paper takes 362 hazardous chemical road transport accidents in coastal areas of China during 2016-2020 as an example. Statistical analysis is carried out from the time distribution of accidents, province distribution, category and form of hazardous chemicals, accident type, accident cause and other aspects. The results showed that: in the past five years, the transportation accidents of hazardous chemicals in China have been decreasing year by year. May, September and December of each year is the peak period of accidents. The morning of each day is the peak period of accidents. In coastal areas, Guangdong, Jiangsu and Zhejiang provinces have a larger number of hazardous chemical accidents. The number of liquid hazardous chemical accidents are high. The number of explosive hazardous chemical accidents is small but the consequences are serious. The driver and environmental factors are the most critical, among which the driver's illegal operation, rainy days, curves can easily lead to transportation accidents.
