Hazard Classification Research Paper

1. Introduction.

a. Nowadays as we all know that the world already has millions of chemicals and is being added every day. The high number and types of chemicals circulating in the world today would have hazards that require special handling and treatment by the user. MSDS existence in the world can not be separated from the element of risk and danger of the chemicals used both to humans and to the surrounding environment. The many types of chemicals which also has the type and nature of the hazard varies have made the world as International and regional mandates to always provide MSDS sheets prior to a chemical sold. It becomes essential character because MSDS is a source of information becomes material for Hazard Communication either by the Company

8. GHS in Malaysia. Chemicals Classification according to CLASS & ICOP.

a. It describes the method of classifying chemicals according to their physical, health, and environmental hazards. It contains the criteria for classifying the chemicals, decision logics, and hazard communication elements for each hazard classes. There are 16 hazard classes under physical hazards, 13 hazard classes under health hazards, and three hazard classes under environmental hazards.

b. The hazard classification covered under the scope of the Regulations is summarised as below:
