A question for the Fire Safety guys.
We have a training room, measuring 117.56 sq m. It has three Fire Exits, one of which leads directly to a protected staircase. The trainers want to accomodate between 70 - 100 people for a seminar. Is this room suitable sized for that amount of people?

I believe for a commitee room / seminar then 1.0m2 would be sufficient. Generally you would require more than one exit if there are more tahn 60 people in a room. So I would say yes, of course there may be other factors I am not aware of e.g travel distances to the nearest exit.etc.

I would agree with the previous answer however it is also important to think about the space required for effective training - space for notes etc

Hope I've got this right but training rooms are excluded from the Workplace (Health, Safety and Welfare) Regulations 1992 (reg 10). Therefore fire safety is the key area of concern and clearly there must be wheelchair access/egress at all times.

Sorry that should read 1.0m2 per person

Is this room suitable sized for that amount of people? Two exits may be suitable but it depands how they are located? Two directions of travel? One leads to a protected stair, where do the other two go? What floor is the room on? Travel distances to final exits?

Hi Chris, This is very long winded to answer, because its actually very complicated to assess. To work out your maximum number of people you can fit into this room, you will have to work out the `density factor'. This is worked out by dividing the area of the room, by the available floor space per person, discounting chairs tables etc. I would move all the equipment to one area of the room, and then measure, this makes it easier to get a measurement. For a training room, this should work out 1 m2 meters per person (as a minimum). Once this calculation has been complete, you will then have to look at the width of the emergency exit for that room, and how many exits. 1-60 persons = 1 exit. 61-600 = 2 exits. 1-60 750mm width of exit, 51-110 850mm exit (wheelchair users will require minimum of 900mm exits), I would factor this in as a given, just in case. You then need to factor in the travelling distance to point of exit, this is a minimum of 18m for single escape exits, and a minimum of 45m for more than one direction exits. All of the calculations above, are if the room leads directly to an emergency exit. If this is not the case, you will have to use the calculations above for the ground floor in its entirety. This will mean calculating the `Density Factor' for all the rooms, that could use the exit that that room leads on to/from, excluding the stairs, corridors, lifts etc. If there are more than two floors, you are starting to get into complex Risk Assessments, which really, you should be going to a specialist for guidance. The Approved Document B will give you further guidance/references. Just remember, the design of the room is very important, in terms of keeping exits clear etc. hope this helps.

Not forgetting the CO2 levels given that level of occupancy - hope it isn't going to be a long session!

What is all that about? All he wants to know is if he can hold training for up to 100 guys in a room that has 3 fire exits.

Murray - As stated, its not that simple. I would be very concerned if a Chartered Safety Practitioner only handed out simple advice, and did not warn those of other areas of concern! Could you point out any of the information that is included, that is not relevant? I may learn something. Perhaps you have not understood, that this is actually a Fire Safety related question?
