Class 1 Dangerous Goods Examples & Labels

CLASS 1 - Explosives. 1.1 A substance or article with a mass explosion hazard. 1.2 A substance or article with a fragment projection hazard, but not a mass explosion hazard.

​Ammunition/cartridges, Fireworks/pyrotechnics, Flares, Blasting caps / detonators, Fuse, Primers, Explosive charges (blasting, demolition etc), Detonating cord, Air bag inflators, Igniters, Rockets, TNT / TNT compositions, RDX / RDX compositions, PETN / PETN compositions.

341.11 Class 1 Divisions

Examples are black powder, nitroglycerine (desensitized), dynamite, most types of torpedoes, and mercury fulminate. Division 1.2 consists of explosives that have a projection hazard but not a mass explosion hazard.

Hazard Class 1: Class 1 hazards are explosives or any devices or chemicals that are designed to explode or combust. Class 1 explosives are illustrated by an orange placard with their designated hazard class, division number or compatibility letter displayed at the bottom. Some also feature an explosion graphic.

Class 1 explosives are composed of various divisions—including Division 1.1G, 1.3G, 1.4G, and 1.4S. The HMR classify consumer fireworks as Division 1.4G explosives.

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.

Examples of commonly transported explosives

Examples for explosive dangerous goods are ammunition/cartridges, fireworks/pyrotechnics, flares, blasting caps/detonators, fuses, primers, explosive charges (blasting, demolition etc.), detonating cord, igniters, rockets, trinitrotoluene (TNT).

Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C). Flammable liquids are divided into four categories as follows: 1. 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.

What is an example of an explosive substance? ›

Examples of explosive and potentially explosive chemicals include: Compounds containing the functional groups azide, acetylide, diazo, nitroso, haloamine, peroxide, and ozonide. Nitrocellulose. Di- and Tri-nitro compounds.

The term “explosives” shall include all material which is classified as Class A, Class B, and Class C explosives by the U.S. Department of Transportation, and includes, but is not limited to dynamite, black powder, pellet powders, initiating explosives, blasting caps, electric blasting caps, safety fuse, fuse lighters, ...

1. An explosive substance is a solid or liquid substance (or mixture of substances) which is in itself capable by chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings.

The movement of class 1 materials is tightly regulated, especially for divisions 1.1 and 1.2, which represent some of the most dangerous explosives, with the greatest potential for destruction and loss of life.

Class Definition

The Classes define the type of explosive or ignitable substances which are present in the atmosphere such as: • 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 2 Hazardous Materials: Gases

However, even non-flammable, non-toxic gases are hazardous, either because they're under pressurized storage or because they're a potential asphyxiant. Common examples of Class 2 hazardous materials include propane, helium, oxygen, and aerosols.

Hazmat Class 1 are explosive materials which are any substance or article, including a device, which is designed to function by explosion or which, by chemical reaction within itself is able to function in a similar manner even if not designed to function by explosion.

It may never be known with certainty who invented the first explosive, black powder, which is a mixture of saltpetre (potassium nitrate), sulfur, and charcoal (carbon). The consensus is that it originated in China in the 10th century, but that its use there was almost exclusively in fireworks and signals.

Definitions. Class I Locations: Are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.
