I wouldn't put anything in common areas of flats 99% of the time. If they really want to help beyond that expected of them give everybody a fire blanket.
I think it depends very much AB on whether this is LA or private. My thoughts would be yes, provide blankets in each kitchen in the former, if an extinguisher is deemed neccessary and a blanket and Co2 and blanket in common areas of the latter. I would not go for DP, due to the mess, nor water in case someone electrocutes themselves. Most dwelling fire are electrical or cooking.
Appropriate extinguishers to cover internal car parks and electrical switchrooms.
These are private flats managed by manageing agents.
What are the hazards and what exactly are the the appropriate risk control measures.
The hazards are virtually negligable in the communal areas. When I visited the only hazards were a bed (obviously left by a resident) in the hallway, a refuse area separated from the communal areas by what looked like a fire door and electrical meter cupboards which are enclosed and accessed by a door which might or might not be a fire door. Everything else is brick or concrete.
I have given the client three options
1 x 6Litre Foam Extinguisher per floor
or
1 x 6Litre Foam Extinguisher and
1 x 2kg CO2 Extinguisher per floor
or
2 x 6Litre Foam Extinguishers and
1 x 2kg CO2 Extinguisher per floor
all plus Fire Exit signs
Fire Door Keep Shut signs
Fire Door Keep Locked signs
Electrical Hazard Signs
Fire Action Notices
Fire Door Keep Clear signs
The problem I have is that even though the communal areas are small (30m/2) for me to ensure that the client complies with BS 5306 Part 8 they should choose the last option.
