A fire extinguisher must be available near the laboratory exit or in the hallway and within 25 meters of the laboratory. It is generally recommended that laboratories be equipped with ABC type fire extinguishers. The fire extinguisher must be clearly labeled and readily accessible for use and inspection. Once discharged, it must be serviced by a qualified technician or replaced.
| Type of Fire Extinguisher | Type of Fire |
| Class A | Ordinary combustible materials (paper, wood, cardboard, most plastics.) |
| Class B | Flammable or combustible liquids (gasoline, kerosene, grease, and oil.) |
| Class C | Electrical equipment (appliances, wiring, circuit breakers, outlets.) |
| Class D | combustible materials often found in chemical laboratories (magnesium, titanium, potassium, sodium) |
Depending on laboratory operations, additional fire suppression equipment such as a fire blanket, clean agent fire extinguisher, or other specialized equipment may be required.
