How many fire extinguishers do I need?
What is the maximum distance between fire extinguishers?
Under Singapore Standard 578:2019, for class A fires, the maximum distance one should require to reach a fire extinguisher should not be more than 15 meters.
Fire Armour’s Commentary on this clause:
If one were to draw a circle around a fire extinguisher with the radius of 15meters, the distance may seem very huge at first. However, using a circle on a floor plan would result in a lot of blind spots. This is why it would be better to trim the area from a circle to a square instead.
The calculations also do not include doorways which would certainly increase the distance required to reach a fire extinguisher. Hence, if there are partitions, the owner has to take these into account.
