A fire watch is a period of time when trained staff continually survey the affected area of the building inspecting for fire. The fire watch is performed by dedicated staff with no other responsibilities.
NFPA Standard LS.01.02.01 requires that facilities provide protection for occupants of the building during the time the Life Safety Code is not met, including during maintenance or construction. During these times, the fire department must be notified, and a fire watch initiated.
A fire watch shall be provided during hot work activities and shall continue for not less than 30 minutes after the conclusion of the work. The fire watch shall include the entire hot work area.
