I just asked the local FRS for advice on fire safety regarding paint spray booths, they said they don't give advice to businesses ? That's why I'm here now! I have an idea what is required but I'll offer it to you chaps. A building about 100 years or so old has a spray booth on the first floor, wet pipe sprinkler system well maintained with heads under the canopy. There is no fire separation - I believe there should be but there will be a cost to the owner. What level of fire compartment would be required? Cheers.

There are three floors and a basement. 2nd floor and basement not occupied. Staircase is part concrete from ground floor up then timber with open treads to the first floor. Not sealed at all, terminates in a means of escape corridor at ground level. The spray booth is in a room approx 10 m by 7 m with double doors to another room the same size where hand spraying takes place. (10m by 14 m). No fire doors at all. Occupancy is 10 maximum with 4 on the first floor. Travel distances are fine but no fire separation. My view is to recommend half hour fire doors at the extremes of the spraying areas and to protect the staircase with half hour fire doors top and bottom. Problem here is cost. They already told me they can't afford emergency lighting so want torches, that's OK with the right regime. Fire safety officer has been in and told them to update the fra and will be back to check, fire safety lady mentioned compartmentation.
