Posted By Darren Honeyford Can anyone help, in the Workplace Regs it states 'the total volume of the room, when empty, divided by the number of people normally working in it should be at least 11 cubic metres'. I would like to know have many cubic metres there are in 2,000 square metres and how do you go about the calculation.

Posted By Paul Huber Darren, You need to multiply your floor space by the height of the room with the following conditions: Do not calculate above 3m, that is if your room is 2000 sq m and 6 m high only multiply by 3 not 6. Only use space that is usable, eg not under stairs, etc. due consideration should be given for the amount of equipment, etc in the room. You must consider the total space, traffic routes, etc and apply a little common sense. I have calculated this in the past and found that the space has to be very small to fall fould of the 11 cubic metre rule.
