Depends of the type of fire extinguisher.
Common CO2-extinguishers are filled with with compressed CO2. Once released it cooles down the fire below it's burning- or ignition-temperature and replaces the Air. The lack of oxigens will then suffocate the fire.
No matter what type of extinguisher, it's always about cooling of suffocating the flame.
A fire extinguisher stops a combustion reaction by removing one or more of the essential components of fire: heat, fuel, or oxygen. Different types of extinguishers work through various mechanisms; for example, water extinguishers cool the fire by absorbing heat, while foam extinguishers smother the flames, cutting off the oxygen supply. Dry chemical extinguishers interrupt the chemical reaction itself, effectively disrupting the combustion process. By targeting these elements, fire extinguishers effectively halt the fire's ability to sustain itself.

Yes. This is why it is important to have them serviced regularly.
Not elemental hydrogen, no. That would not work in a fire extinguisher as hydrogen is highly flammable. Some fire extinguishers do use water, however, which is a hydrogen compound.
No, hence them being Class D fire extinguishers they are only used on combustible metal fires. there are different class d extinguishers as well for specific metal fires no one class d extinguisher on all metal fires mostly very specific
It depends on the type. If it's not readily apparent, you should probably just get a new one.
Usually CO2. Hydrogen and oxygen are fuels for fire. Nitrogen would work but is not usually used as it is too light.
Two things which work on the principle of biotech and chem tech is a galvanometer apparatus and fire extinguisher.
You will need to become an expert in how fire extinguishers work. Not only in terms of using them, but you'll need to be able to train others in their use as well.
They have specially made foaming extinguishers for this sort of thing, perhaps suffocating it (if it is very small) may work as well.
Chemical fire extinguishers are designed to suppress or extinguish fires by using various chemical agents that interrupt the combustion process. They can be effective against different types of fires, depending on their specific chemical composition, which may include dry chemicals, foam, or wet agents. These extinguishers work by cooling the flames, suffocating the fire, or chemically disrupting the reaction that sustains combustion. Proper selection and use of the appropriate type of chemical extinguisher are crucial for effective fire control.
Class A fire extinguishers are designed to put out fires involving ordinary combustible materials such as wood, paper, and textiles. They work by cooling the burning material to remove heat, which is one of the three elements of the fire triangle (heat, fuel, and oxygen). While they do not directly remove oxygen or fuel, by extinguishing the heat, they effectively prevent the fire from continuing to burn.
