Laboratory Fire Safety

Organizational units with teaching, research, and clinical laboratories will adopt and implement controls outlined in the University Laboratory Safety Manual (LSM) to mitigate the risk of fire, explosion, uncontrolled reaction, and hazardous materials spills.

Hazardous Materials

Information on chemical storage and use, including quantity limits prescribed in the International Fire Code, can be found in LSM Section 2. Information on fire safety equipment may be found in LSM Section 4.

Additional information on hazardous materials, compressed gas, laboratory and shop entry safety caution signs, Seattle Fire Department Permits, and using refrigerators and freezers to store flammable liquids is available on the Hazardous Materials webpage.

Refrigerators and Freezers

Flammable liquids should not be stored or cooled in a refrigerator unless it is specifically designed for this purpose; doing so may result in an explosion. Explosion-proof refrigerators that have been specifically designed to meet NFPA and OSHA standards for volatile materials, and are UL listed for flammable materials must be used when storing or cooling flammable or volatile materials. See more information at Refrigerators and Freezers: Storing Flammable Liquids.
