4. Halogen, carbon dioxide, and dry powder fire extinguishers should be used to fight fires of live equipment;
5. Dry powder and halogenated alkane fire extinguishers should be used to fight fires of Class A, B, C, and live equipment;
6. Special dry powder fire extinguishers should be used to fight Class D fires.
Types of fire extinguishers and protection objects
1. Carbon dioxide, carbon tetrachloride, 1211, difluorodibromomethane, 2402, 1301, heptafluoropropane, and hexafluoropropane should be used for saving cultural relics files;
2. Dry powder, carbon dioxide, carbon tetrachloride, 1211, difluorodibromomethane, 1301, 2402, heptafluoropropane, hexafluoropropane, and alcohol-resistant foam should be used for fighting flammable liquids;
3. Dry powder, carbon dioxide, carbon tetrachloride, 1211, difluorodibromomethane, 1301, 2402, heptafluoropropane, hexafluoropropane should be used for fighting flammable gases;
4. For electrical equipment fires, dry powder, carbon dioxide, carbon tetrachloride, 1211, difluorodibromomethane, 1301, 2402, heptafluoropropane, and hexafluoropropane should be used;
5. Carbon dioxide, carbon tetrachloride, 1211, difluorodibromomethane, 1301, 2402, heptafluoropropane, hexafluoropropane should be used for precision instrument fire.
Fire extinguisher agent toxicity
1. 1211 (difluoro-chloro-bromomethane), slightly aromatic at room temperature, toxic, it must be ventilated after use to prevent poisoning or suffocation;
2. 1301 (trifluoro-bromomethane), slightly aromatic at room temperature, toxic, it must be ventilated after use to prevent poisoning or suffocation;
3. 2402 (Tetrafluorodibromoethane), slightly aromatic at room temperature, toxic when exposed to heat and high temperature, you must wear a gas mask when using it;
4. 1202 (Difluorodibromomethane), with a slightly aromatic smell at room temperature, and toxic, so it must be ventilated after use to prevent poisoning or suffocation;
5. FM200 (HFC-227ea), colorless and odorless at room temperature, non-toxic, no ventilation after use;
6. Carbon dioxide (CO2), non-toxic and tasteless at room temperature, and the gas is suffocating. Ventilate after use to prevent suffocation;
7. Carbon tetrachloride (CCl4) has a slightly sweet taste at room temperature and is toxic when exposed to open flames. It must be ventilated after use to prevent suffocation;
8. Dry powder (NaHCo3), non-toxic and tasteless at room temperature, can irritate the respiratory tract when extinguishing fire, it must be ventilated after use;
9. Dry powder (NH4H2PO4), non-toxic and odorless at room temperature, irritating the respiratory tract when extinguishing a fire, it must be ventilated after use;
10. Dry powder (NH4H2PO4+NaHCo3), non-toxic and odorless at room temperature, can irritate the respiratory tract during fire fighting, and must be ventilated after use.
