(d) Where the floor area of a building is less than that specified in Table 2, at least one extinguisher of the minimum size recommended shall be provided.

(e) The protection requirements may be fulfilled with extinguishers of a higher rating provided the travel distance from anywhere in the building to such larger extinguishers shall not exceed 75 ft (22.7m), as shown in Table 2 above.


Fire Extinguisher Size and Placement for Class B Fires other than for Fires in Flammable Liquids of Appreciable Depth

(a) Minimal sizes of fire extinguishers for the listed grades of hazard shall be provided on the basis of Table 3. Extinguishers shall be located so that the maximum travel distances from anywhere in the building shall not exceed those specified in the table used.

EXCEPTION: Extinguishers of lesser rating, desired for small specific hazards within the general hazard area, may be used, but shall not be considered as fulfilling any part of the requirements of Table 3.


    Maximum Travel  
  Basic Minimum Distance to  
  Extinguisher Extinguisher  
Type of Hazard Rating (in feet) (in meters)
Light (low) 5B 30 9.15

Ordinary (moderate) 10B 30 9.15
  20B 50 51.25
Extra (high) 40B 30 9.15
  80B 50 15.2
NOTE 1: The specified rating does not imply that fires of the magnitudes indicated by these ratings will occur, but rather to give the operators more time and agent to handle difficult spill fires that may occur.

NOTE 2: For fires involving water soluble flammable liquids see Section 566 (d).

NOTE 3: For specific hazard applications see Section 566.

(b) Two or more extinguishers of lower rating shall not be used to fulfill the protection requirements of Table 3.
(c) The protection requirements may be fulfilled with extinguishers of higher ratings provided the travel distance to such larger extinguishers shall not exceed 50ft.(15.25m) as shown in Table 3.


Fire Extinguisher Size and Placement for Class K Fires.

(a) Fire extinguishers with a Class K rating shall be provided for hazards where there is a potential for fires involving combustible cooking media (vegetable or animal oils and fats).

(b) Maximum travel distance shall not exceed 30 ft (9.15m) from the hazard to the extinguishers.


Frequency of Inspection, General.

Fire extinguishers shall be inspected, at least monthly by the building owner occupant or his/her authorized agent.

574.2. ​​​​​​​Procedures Monthly inspection of extinguishers shall include a check of at least the following items:
(a)  Located in the designated place.
(b)  No obstruction to access or availability.
(c)  Operating instructions on nameplate legible and facing outward.
(d)  Safety seals and tamper indicators not broken or missing.
(e)  Examine for obvious physical damage, corrossion, leakage, or clogged nozzle.
(f)   Pressure gauge reading or indicator in the operable range or position.
(g)  Determine fullness by hefting and, if needed, by weighing.
(h)  For wheeled units, condition of tires, wheels, carriage, hose, and nozzle checked.



(a) Personnel making inspections shall keep records of all fire extinguishers inspected, including those extinguishers that were found to require corrective actions.

(b) At least monthly, the date the inspection was performed and the initials of the person performing the inspection shall be recorded on a tag or label attached to the fire extinguisher, or an inspection checklist maintained on file, or an electronic system (e.g. bar coding) that provides a permanent record.


Maintenance and Required Service Intervals. 

(a) Fire extinguishers shall be subjected to maintenance annually as described in this chapter or immediately after use or when specifically indicated by an inspection or at the time of hydrostatic test. For purposes of maintenance, hydrostatic tests required during the same calendar year shall be performed at the time of the annual maintenance or recharge.

(b) Nonrechargeable fire extinguishers shall not be recharged or hydrostatically tested but shall be discharged and removed from service at a maximum interval of 12 years from the date of manufacture.
