FLAMMABLE/COMBUSTIBLE CHEMICALS

Among the most hazardous materials in the Clinical Chemistry laboratory because of possible fire or explosion.

FLAMMABLE/COMBUSTIBLE CHEMICALS

They are classified according to flash point — which is the temperature at which sufficient vapor is given off to form an ignitable mixture with air.
