While some of those factors are rather fine points fire marshals understand how important it is to take into consideration the purpose for the space and how it is related to safety issues.
Meeting room capacity fire regulations.
For example a 2000 square foot assembly room at a school could accommodate 100 students based on square footage alone.
If you measured the room in sections add up the square feet of each section.
Capacity calculation methodology for schools.
Issue 04 1 0 introduction.
A room with only 1 exit no matter the size is limited to 50 people.
The attached approved code of practice explains that this means people.
You can use the following methodology to calculate the capacity of rooms in your school based upon fire safety standards.
Figure the area of the room by multiplying the length by the width.
To calculate a room s maximum occupancy determine factors such as the area of the room the available space in the room the number of useful exits and the height of the ceiling.
If that room only has a single exit the international building code limits occupancy to 50 people to make it more likely that everyone in the room will have time to exit if a fire takes hold.
For a room with multiple exits that are remote from each other generally you calculate 2 inches per person in the exiting capacity for an unsprinklered building.
Workplace health safety and welfare regulations.
The maximum number of persons it is designed to hold this can be determined by dividing the area of the room m2 by an occupancy factor this varies depending on the use to which the room is to be put and is summarised in table 1 below.
The capacity limits depend upon your specific building the fire escape strategy designed for that building and a number of other factors including.
Calculate a basic estimation of a room s maximum occupancy by dividing the available floor space in square feet by 36.
Room dimension space for welfare and fire safety.
Means of escape there is a limit to the number of people you are allowed to have on a floor which is governed by the building regulations 2010 and part b of the approved documents fire safety.
The method involves two separate calculations.
1 1 the figure used for room capacity is determined by two separate factors.
The total usable area of the room divided by the occupancy factor.
For example if your room is 50 feet long and 40 feet wide the area is 2 000 square feet 50 x 40 2 000.
