- What Kind of extinguisher should I use?
The National Fire Protection
Association (NFPA) classifies fires into five general
- Class A fires are ordinary materials like
burning paper, lumber, cardboard, plastics etc.
- Class B fires involve flammable or
combustible liquids such as gasoline, kerosene, and
common organic solvents used in the laboratory.
- Class C fires involve energized
electrical equipment, such as appliances, switches,
panel boxes, power tools, hot plates and stirrers.
Water can be a dangerous extinguishing medium for
class C fires because of the risk of electrical
shock unless a specialized water mist extinguisher
- Class D fires involve combustible metals,
such as magnesium, titanium, potassium and sodium as
well as pyrophoric organ metallic reagents such as
alkyllithiums, Grignards and diethyl zinc. These

violently with water, air, and/or other chemicals.
