Are all hazardous products classified into groups classes and categories?

Hazardous products are divided into two hazard groups: physical hazards and health hazards. The two hazard groups are further divided into hazard classes. Each hazard class contains at least one category. The hazard categories are assigned a number (1, 2, etc.).

Why are hazardous products classified into classes and categories?

The category tells you about how hazardous the product is (that is, the severity of hazard). Category 1 is always the greatest level of hazard (that is, it is the most hazardous within that class). If Category 1 is further divided, Category 1A within the same hazard class is a greater hazard than category 1B.

Why is it important to have a classification system for hazardous chemicals?

The purpose of classification under the GHS is to provide harmonized information to users of chemicals with the goal of enhancing protection of human health and the environment. Many countries already have regulatory systems in place for chemical classification and hazard communication.

Why do we classify hazards?

The Occupational Safety and Health Administration has taken steps to try and keep these workers safe. Through hazard identification, chemicals and other dangers in a workplace are classified according to the risks that they present.

Why do we need to know the different classes of chemicals?

Chemicals are classified so that people using them - either in industry or as consumers - can understand any hazardous effects they could have on human health or the environment and to protect against that harm. Classification is about identifying intrinsic hazards, not controlling risks.

How do you categorize chemicals?

Chemicals can be classified by their structure (e.g., hydrocarbons), uses (e.g., pesticides), physical properties (e.g., volatile organic compounds [VOCs]), radiological properties (e.g., radioactive materials), or other factors.

How many chemical classes are there?

Many of these substances can be grouped into “Six Classes”, each containing similar chemicals. The Six Classes approach allows us to better understand these chemicals, their functions, where they are used, and how they can be avoided.
