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.
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.
To label the density of a solid, you would typically use the unit of mass divided by volume. The density of a solid is calculated by dividing its mass by its volume. The units commonly used for density are grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
A wheel well fire is unique because it can be four of the five fire classes:the tires are Class A--flammable solidsthe fluids are Class B--flammable liquidsyou've probably got electrical actuators in there, so you've also got a Class C--electrical--fire on your hands.and the plane has some aluminum, magnesium and maybe titanium components; heat them up enough and you're looking at a Class D--flammable metals--fire.What it WON'T be is a Class K--kitchen flammables--fire.In the air you'll just use your Class ABC built-in suppression system. If you land the thing on fire, they'll use Aqueous Film Forming Foam.
Very. It is usally used for camp fuel and other flameable things
because it is highly flammable
paraffin
Class D Class D fire extinguishers are used for various types of flammable metals. A class D fire extinguisher can contain sodium chloride, graphite, or copper powder. A sodium chloride fire extinguisher would be used on metals containing magnesium, sodium, potassium, and sodium-potassium alloys. Copper and graphite fire extinguishers would be used for lithium and lithium alloy fires.

Class 0: up to 1000 V, red label, used for delicate work Class I: up to 7500 V, white label Class II: up to 17000 V, yellow label Class III: up to 26500 V, green label Class I,II,II used for all other electrical work
It indicates a flammable or explosive gas.
Class A fires are fires involving solid flammable material like wood or paper. Class B fires are flammable chemicals such as gasoline or alcohol. Class C fires are electrical in origin. The numbers on each category describes how effective this fire extinguisher is for each type of fire.
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.
A Class A (or ABC) extinguisher would be used to extinguish a paper fire. Class A - Ordinary Combustibles Class B - Flammable liquids Class C - Electrical fires Class D - Flammable metals Class K - Kitchen fires (organic fats/grease)
There is no such thing as a Class 3.1, or a Division 3.1 in the DOT scheme of classifying hazardous materials. The International Maritime Dangerous Goods Code used to use a Division 3.1 for the most flammable of flammable liquids, but that was removed from the code more than 10 years ago. At present, hazardous materials may be described simply as "Class 3" if they meet the definition of flammable liquids.
General purpose extinguisher, can be used for most fires (except cooking fats)
Class B: Class B extinguishers are used on fires involving flammable liquids, such as grease, gasoline, oil, and oil-based paints.
A flammable gas is in Division 2.1 in the widely used classification of hazardous materials recommended by the UN Committee of Experts and adopted by the US Department of Transportation, among other nations.
