This is a subcategory of fire suppression equipment designed for initial firefighting and fire spread prevention in factories and business facilities. It covers a wide range from portable fire extinguishers including powder, foam, carbon dioxide, and halogenated compound extinguishers to fixed fire suppression systems such as sprinkler systems, foam suppression systems, gas suppression systems, and indoor fire hydrant systems. It includes specialized fire suppression agents for specific fire risks in manufacturing environments (oil fires, electrical fires, chemical fires) and residue-free suppression systems for cleanroom applications. The focus is on equipment subject to mandatory installation under fire protection laws and devices requiring periodic inspections, clearly distinguished from other fire prevention equipment such as fire alarms and emergency exit lights.
