What is distance to place one fire extinguisher to other fire extinguisher?

Answer 1

Someone initially said: 1500ft.

State and local fire codes may have different criteria based upon the type of occupancy and the level of hazard.

For example, in an ordinary Class A hazard (paper, plastic, wood, cloth), you may need a Class 2-A or 4-A fire extinguisher within 75 feet of travel distance from any interior location, or one for every 11,250 square feet. For Class B hazards, a 5-B may be required within 30 feet for low hazards and a 50-B may be required within 50 feet of a high hazard, among many other possible combinations.

NFPA 1 (2009) Fire Code: 13.6.8.2, 13.6.8.3.

US Coast Guard regulations prescribe the minimum number and size of fire extinguishers, if any, required aboard various vessels.

In a commercial kitchen, a Class K extinguisher may be required within 30 feet.

NFPA 1 (2009): 13.6.8.6

Your local codes may vary.

Answer 2

Depending upon type of hazard and size of extinguisher:

Class A would be no more than 150 feet apart (75 ft max travel) for 11,250 sq ft.

Class B would be either 60 feet or 100 feet max, depending upon size of extinguisher.
