PQS extinguishers are effective in extinguishing fires classified into three main types:

• Type A: Fires in solid combustible materials such as wood, paper or cloth.
• Type B: Fires in flammable liquids such as gasoline, oil, solvents and other chemicals.
• Type C: Fires originated by energized electrical equipment (for example, short circuits or faults in electrical installations).

The dry chemical powder acts by smothering the fire by covering the burned surface with a layer that interrupts the chemical reaction of the fire.

Recommendations for customers who should purchase PQS extinguishers:

1. Industrial and commercial companies: All types of businesses that handle flammable materials (liquids, solids or gases) or electrical equipment must have PQS extinguishers. This includes factories, chemical warehouses, vehicle workshops and stores with electrical equipment.
2. Offices and multi-story buildings: PQS extinguishers are ideal for offices and buildings that contain electrical equipment, flammable furniture and combustible materials on the premises. Their versatility makes them a recommended choice in these environments.
3. Establishments at risk of electrical fires: Companies with complex electrical installations, computer servers, telecommunications systems or industrial machinery should have PQS extinguishers, as they are suitable for electrical equipment fires without putting workers at risk.
4. Transportation and vehicles: Transportation vehicles (trucks, buses, heavy machinery) must be equipped with PQS extinguishers due to the risk of engine fires and accidents involving flammable materials.
5. Hospitals, clinics and health centers: Although hospitals are places where flammable materials predominate to a lesser extent, the presence of sensitive electrical equipment makes a PQS extinguisher a necessity.
6. Retail stores and stores: Businesses that sell flammable products such as paints, cleaning chemicals or liquids in general should have PQS extinguishers near storage or display areas.
