Hi I am a 76 yr lady living in black of flats over 55s each flats entrance door is a fire door. Tenants have been wedged the doors open or have them tied back.I have spoken to the responsible person she said they use common sense during the hot weather the doors can be wedged open .I was told this is not allowed who is right

Many of the fatalities at Grenfell were due to their flats doors not closing, allowing the central stair & landings (remote from and not directly affected by the cladding) to be rapidly filled with heat, smoke & toxic gases from the flats being consumed by fire. This why working self closers are the most important issue in flat front doors (& why in some blocks older standard doors are acceptable as long as the closers are suitable).
Common sense goes out of the window in a fire and if none of the 239 people in the Tower remembered to shut their door behind them when escaping you can bet no one in your block will.

The common sense attitude only works until it doesn't - with a fire being a reason for it not working. RP is being lazy and the flats probably need Air Conditioning instead.
