What is hazard category 2? ›

Hazard Class 2: Class 2 hazards are compressed gases, which are divided into four categories: flammable/combustible gases, non-flammable/non-poisonous gases, toxic/poisonous gases, and oxygen.

Section 1, Identification includes product identifier; manufacturer or distributor name, address, phone number; emergency phone number; recommended use; restrictions on use. Section 2, Hazard(s) identification includes all hazards regarding the chemical; required label elements.

Section 2: Hazard(s) Identification

This section identifies the hazards of the chemical presented on the SDS and the appropriate warning information associated with those hazards.

The HAZMAT Class 2 in United States law includes all gases which are compressed and stored for transportation. Class 2 has three divisions: Flammable (also called combustible), Non-Flammable/Non-Poisonous, and Poisonous.

Class II locations consist of locations where combustible dusts may exist that have the potential to become flammable or ignitable. Locations that would be considered to be Class II include Grain elevators, Flour and feed mills, Metal powder manufacturers, and Coal plants, etc.

Category 1 is always the greatest level of hazard within its class. – If Category 1 is further divided, Category 1A within the same hazard class is a greater hazard than category 1B. Category 2 within the same hazard class is more hazardous than Category 3, and so on. There are a few exceptions to this rule.

The hazard class and category will be provided in Section 2 (Hazard Identification) of the SDS. Each hazard class or category must use specific pictograms and other label elements to indicate the hazard that is present, and what precautionary measures must be taken.

Category 1 is always the greatest level of hazard. (In other words, 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. Category 2 within the same hazard class is more hazardous than Category 3, and so on.

There are only two signal words – “DANGER” and “WARNING.” Within a specific hazard class, “DANGER” is used for the more severe hazards and “WARNING” for the less severe hazards.

The CLP Regulation introduce several different classification hazards under the groups; physical, health and environmental. These hazards can range from acute toxicity to environmental hazards to skin sensitisation.

What information is not included in section 2 of the SDS? ›

Section 2: Hazard Identification

It will contain the GHS hazard pictogram(s) along with the hazard and precautionary statements relating to the types of hazards, safe handling, storage and disposal. If a product is not hazardous, this section will not contain any hazard information.

In essence Section 2 covers the safety of the product (which might be a mixture of ingredients) as used and Section 16 will mention all of the components which may not pose a risk as they are in small concentration but it might be useful to know depending on what for or how you are using the product.

Subsets of Class 2 are:

2.1 Flammable Gas – Hydrogen Compressed, Ethylene, Butylene, Acetylene, etc. 2.2 Non-Flammable Gas – Oxygen Compressed, Nitrogen Compressed, etc. 2.3 Poisonous Gas – Phosgene, Sulfur Tetrafluoride, Insecticide Gasses, etc.

IPC Class 2 refers to dedicated service electronic products. Dedicated service electronic products include sophisticated business machines, radio and telecommunications equipment, instruments, etc.

Class I locations are those in which flammable vapors and gases may be present. Class II locations are those in which combustible dust may be found. Class III locations are those which are hazardous because of the presence of easily ignitable fibers or flyings.

Category 2 shall include liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point above 95 °F (35 °C).

Risk level 2: Materials hazardous to health, but areas may be entered freely with full facemask self-contained breathing apparatus that also provides eye protection.
