What are the main concerns for each physical hazard class? These four classes cover products that have the ability to ignite (catch fire) easily and the main hazards are fire or explosion. These three classes cover oxidizers, which may cause or intensify a fire or cause a fire or explosion.

Also, how many classes can a hazardous product belong to?

GHS Hazard Classification. GHS uses three hazard classes: Health Hazards, Physical Hazards and Environmental Hazards. These aren't required by OSHA. Health hazards present dangers to human health (i.e. breathing or vision) while physical hazards cause damage to the body (like skin corrosion).

Similarly, what is a health hazard class under the Hazardous Products Regulations? Health Hazards Group: Hazardous products are classified in this group based on their ability to cause adverse health effects such as acute toxicity, respiratory sensitization (such as breathing difficulties, asthma or allergy), eye irritation or carcinogenicity (ability to cause cancer).

Also, can a product be classified under more than one hazard class?

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. There are a few hazard classes with five or more categories (for example, “Organic peroxides”).

What are the 3 classification of hazard?

Such hazards are categorized into three classes: biological, chemical and physical. Biological hazards include harmful bacteria, viruses or parasites (e.g., salmonella, hepatitis A and trichinella). Chemical hazards include compounds that can cause illness or injury due to immediate or long-term exposure.
