Fire prevention and initial firefighting equipment for factories and industrial facilities. Includes various types of fire extinguishers such as dry powder, foam, CO2, and halogenated compound extinguishers, fire hydrant systems, sprinkler systems, foam fire suppression systems, and inert gas fire suppression systems. Covers industrial firefighting equipment designed for special manufacturing environments (high-temperature furnaces, oils and fats, electrical equipment, chemicals) and equipment mandated by fire safety regulations. Distinguished from alarm and guidance equipment like fire detectors and emergency exit lights, this classification focuses specifically on equipment and systems used for actual firefighting operations.
