Suppression Agents

Suppression agents are materials or substances used to extinguish fires in space and astronautical engineering contexts. These agents work by interrupting the chemical reaction that sustains the fire. Common suppression agents include water, carbon dioxide, halon, and dry chemical powders. Water is effective for extinguishing fires involving solid materials, while carbon dioxide is used for electrical fires. Halon is a clean agent that is effective for extinguishing fires in enclosed spaces, but it is no longer used due to its harmful effects on the ozone layer. Dry chemical powders are versatile and can be used for a variety of fires, but they can leave a residue that can damage equipment.
