Hazard Class 7: Radioactive Material.

What are Class 1.4 explosives?

Division 1.4 consists of explosives that present a minor blast hazard. Examples are common fireworks, toy caps, empty primed grenades, and some small arms ammunition. Division 1.5 consists of very insensitive explosives that have a mass explosion hazard.

What is a Class 1 chemical?

What are Class 1 dangerous goods and why are they classed as dangerous? Class 1 goods are products that possess the ability to alight or detonate as a consequence of a chemical reaction. Explosives are classified as a hazardous product for a pretty clear reason – they can explode.

What is considered a Class 1 explosive?

Class 1, Explosives:

An explosive is any substance or article, including a device or pyrotechnic substance, which is designed to function by explosion (i.e., an extremely rapid release of gas and heat) or which, by chemical reaction within itself, is able to rapidly conflagrate or detonate.

What are Category 1/2 and 3 flammable liquids?

Category 1 shall include liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point at or below 95 °F (35 °C). 2. Category 2 shall include liquids having flashpoints below 73.4 °F (23 °C) and having a boiling point above 95 °F (35 °C). 3.

What is Class 1 C flammable liquid?

Class I liquids are the most hazardous from a fire safety standpoint, while Class IIIB liquids are the least hazardous. Class IA liquids are liquids that have flash points below 73 °F (22.8 °C) and boiling points below 100 °F (37.8 °C). Additionally, unstable flammable liquids are treated as Class IA liquids.
