Class B: fires involving flammable liquids such as alcohol, gasoline, ether, etc.
Class C: fires involving energized electrical equipment
Class D: fires involving combustible metals such as magnesium, zirconium, sodium, lithium, and potassium

The majority of fire extinguishers in the Medical Center are for fire classes A, B, and C. Some areas with special equipment or a specific fire hazard such as the Operating Rooms, have a specific fire extinguisher that have Types B and C carbon dioxide fire extinguishers. The kitchens and cafeterias have Type K fire extinguishers while the MRI Areas have Types A, B, and C Clean Agent non-magnetic fire extinguishers.
Maintenance and Training
Facilities Management conduct monthly inspections of fire extinguishers. It is however a good practice for units to periodically check their fire extinguishers to ensure that these are not missing, blocked, or damaged. If necessary, open a ticket via Service Now (MCSS). Departments may also request fire extinguisher training through Service Now (MCSS).
