The amount of fire marshals that you need in a workplace is dependent on the risk and size of your organisation e.g. how many floors are in the building, how many employees or people you have in one area at one time and accessibility.

As a rule of thumb, those with a low-risk premise could have:

○ At least 1 fire marshal for fewer than 50 employees/occupants
○ 2 fire marshals for 50-100 employees/occupants
○ And 1 additional fire marshal for every additional 100 employees/occupants

Those with a normal-risk premise should have:

○ At least 1 fire marshal for fewer than 20 employees/occupants
○ 2 fire marshals for 20-75 employees/occupants
○ And 1 additional fire marshal for every additional 75 employees/occupants

And finally, those with a high-risk premise should have:

○ At least 1 fire marshal for fewer than 15 employees/occupants
○ 2 fire marshals for 15-50 employees/occupants
○ And 1 additional fire marshal for every additional 50 employees/occupants
