Flammable solids are classified as Class 4 in the Hazardous Materials Regulations. This class includes materials that can easily ignite and burn, such as certain metals, sulfur, and some organic compounds. They are further divided into three divisions: Division 4.1 for flammable solids, Division 4.2 for substances that are spontaneously combustible, and Division 4.3 for materials that emit flammable gases when in contact with water. Proper handling and storage are crucial to minimize fire hazards associated with these materials.
Division 4.1 is for flammable solids. The 4.1 Hazard warning label is used on the outside of packages intended for shipping materials that meet the definition of a flammable solid. These will be things like magnesium and aluminum dust, but not wooden planks.
A flammable solid is classified as a material that can readily catch fire and burn when exposed to a heat source. These solids can ignite spontaneously and pose a fire hazard if not stored and handled properly.
Class A fire: flammable solids--wood, paper, cloth, things like that. Class B fire: flammable liquids Class C fire: electrical fire. A Class C fire is one where electric sparks ignite something else like wood or gasoline, but it's classified differently because it must be extinguished with a nonconductive agent to prevent the firefighters from being electrocuted. Class D fire: flammable metals Class K fire: kitchen fires. These are technically Class B fires--grease is a flammable liquid--but they are very hard to put out, so special extinguishing systems are used.
Solid wire itself is not flammable. However, if the wire is surrounded by a flammable material or exposed to high temperatures, it can act as a heat source and contribute to a fire.

Division 4.1 is for flammable solids.
A hazardous material that is a flammable solid is classified in Division 4.1
A flammable solid would fall into Division 4.1
Class 3 covers flammable liquids.

There are a number of chemicals that are very flammable. Some are even explosive. That makes it hard to pick one. Volatile substances that have light molecules are probably the most flammable, and there are a number of things that could compete for the title "most flammable" or something similar.

Flammabe or not flammable:- gold is not flammable- sulfur is flammable
A flammable solid is classified as a material that can readily catch fire and burn when exposed to a heat source. These solids can ignite spontaneously and pose a fire hazard if not stored and handled properly.
Phosphorus is classified as a DOT Hazard Class 4.2, which designates it as a flammable solid. Specifically, it is categorized as a spontaneous combustible material, meaning it can ignite spontaneously in air under certain conditions. Proper precautions and safe handling are essential when transporting or storing phosphorus due to its reactive nature.
