Class 4 Dangerous Goods are flammable solids. This category of hazardous cargo represents substances which are liable to spontaneous combustion and goods that emit flammable gases when they come into contact with water. Metal powders are particularly hazardous as they are more difficult to extinguish when on fire.Class 4 Dangerous Goods are flammable solids. This category of hazardous cargo Dangerous goods, abbreviated DG, are substances that when transported are a risk to health, safety, property or the environment. Certain dangerous goods that pose risks even when not being transported are known as hazardous materials (syllabically abbreviated as HAZMAT or hazmat). › wiki › Dangerous_goods
What is a Class 4 hazardous material?

- Hazard Class 4 consists of three divisions:
- Examples of flammable solids include certain metallic hydrides, metallic sodium and potassium, oily fabrics, processed metals, matches, and nitrocellulose products.
- The following conditions apply:
What are the 4 flammable hazard classes?
The physical hazard classes are described briefly below. Flammable gases Flammable aerosols Flammable liquids Flammable solids These four classes cover products that have the ability to ignite (catch fire) easily.
What is included in Class 4.1 flammable solids?
4.1 Flammable Solids: Solid substances that are easily ignited and readily combustible (nitrocellulose, magnesium, safety or strike-anywhere matches). 4.2 Spontaneously Combustible: Solid substances that ignite spontaneously (aluminium alkyls, white phosphorus).
19 related questions foundWhat are examples of flammable liquids?
Flammable: A liquid with a flash point under 100°F is considered flammable. Examples: gasoline, acetone, toluene, diethyl ether, alcohols. Hazard: May produce ignitable vapors at normal ambient temperatures.

What is considered flammable liquid?
Flammable liquid is any liquid having a flashpoint at or below 199.4 °F (93 °C).
What is a Class 4 Division 4.1 hazardous material?
Class 4.1 – Flammable solids, etc.
Some are self-reactive, and are liable to break down chemically, if they get above certain temperature, or are subjected to shock etc. They may then decompose explosively, or burn vigorously, or produce toxic gases or vapors.
What are examples of flammable solids?
Ignitability varies significantly from one metal to another. For example, cerium, lutetium and neodymium all have ignition temperatures near 150 C (300 F) and are considered flammable solids. The heat of friction can be enough to initiate ignition of these metals.
What is a Class 1 flammable liquid?
“Class I” FLAMMABLE LIQUID refers to any liquid having a flash point below 100°F and is. subdivided into three classes with some examples listed below: Class IA Flash point below 73 F, boiling point below 100 F. acetaldehyde. ethyl chloride.
What liquid is the most flammable?

Of all the dangerous chemical gases, chlorine trifluoride is known to be the most flammable. It is a colorless and extremely reactive gas that can burn through concrete and gravel.
Is hydrogen peroxide flammable?
Hydrogen Peroxide is not combustible but it is a STRONG OXIDIZER which enhances the combustion of other substances. Flood with water to extinguish fire.
What is super flammable?
A substance is considered highly flammable if its ignition point is lower than 90 degrees F.
How flammable is toothpaste?
Conclusion. Toothpaste is not flammable. It's non-flammable, and you don't need to take safety measures while using it. It doesn't burn or get damaged in any way, unlike some other common household items.
What is a Class 2 flammable?
Class II liquids are combustible liquids that have a flash point at or above 100 °F (37.8 °C) and below 140 °F (60 °C). Typical Class II liquids include liquids such as camphor oil, diesel fuel, pine tar, and Stoddard solvent.

What is a Class 3 hazardous material?
Class 3 dangerous goods are flammable liquids with flash points no more than 60 celcius degrees. It covers liquid substances, molten solid substances with a flash point above 60 celcius degrees and liquid desensitized explosives.
What is a Class 4 hazardous material per the US Department of transportation?
Class 4: Other Flammable Substances
Class 4 products include commodities that are flammable solids, combustible or can be dangerous if they get wet. They make up about three percent of the hazardous materials that CSX moves.
How many subdivisions do we have under Class 4?
Like the majority of the classes of dangerous goods and as briefly touched on above, flammable solids are also placed into their own sub-divisions, in which there are three. Goods that fall under division 4.1 will burn extremely easily, much easier than your ordinary combustible material such as wood and paper.
Can flammable solids spontaneously combust?
SUBSTANCES LIABLE TO SPONTANEOUS COMBUSTION; SUBSTANCES WHICH, IN CONTACT WITH WATER, EMIT FLAMMABLE GASES.
What does Level 4 flammability hazards indicate?
Level 4 – Materials that completely vaporize at normal pressure and temperature and burn readily. Level 3 – Liquids and solids that can be ignited under the most ambient conditions. Level 2 – Materials that must be moderately heated before ignition can occur.
What is a Class 6 hazard?
Hazard Class 6 consists of two divisions: Division 6.1 includes toxic substances, poisons, and irritating material. Examples of Division 6.1 materials (not all of which are mailable) include bromobenzyl cyanide, methyl bromide, motor fuel anti-knock mixtures, and tear gas. Division 6.2 includes infectious substances.
