| 摘要： | In 2004, the Pipeline and Hazardous Materials Safety Administration (PHMSA) revised the incident reporting requirements by eliminating certain exceptions for small quantities of Class 3 hazardous material (HAZMAT). In the following years the number of incident reports filed for small quantities of Class 3 HAZMAT has increased substantially. On the other hand, a large number of products that are currently not regulated under the Hazardous Materials Regulations (HMR) will become a regulated Class 9 HAZMAT under the United Nations Globally Harmonized System (GHS) of Classification and Labeling of Chemicals criteria. Consequently, the number of reported incidents involving Class 9 HAZMAT in transportation is likely to increase significantly in the near future. Due to the changes in the regulations along with the GHS classification scheme adopted at the international level, there is an increasing interest among the various stakeholders in better understanding the safety and risks associated with various commodities comprising Class 3 (Packing Groups II and III) and Class 9 HAZMAT. The objectives of the current research were set to identify the commodities comprising Class 3 (Packing Group (PG) II and III) and Class 9 liquid HAZMAT (UN 3082) and to determine the risks of transportation of the HAZMAT in commerce by motor carriers. All analyses performed were based on a maximum single package capacity of the hazardous materials of eight gallons. |
