Many fire safety practioners (without a profit incentive) in those days , never believed in open fire doors.
The original concept of residential care as an industry started in the 60's and 70's when the welfare state kicked in, the standards applied were the standards found of that time i.e. old lathe and plaster, bits of supalux nailed onto the back of doors, tap tap and a knock tested doors, 25mm rebates . etc. etc.
Many fire authorities in the 90's realised that the figures of fires in residential care and the casualties were rising, and may be, before tomb stone law became the way, that a change was needed.
In the old days the most fire risk in a bedroom was bed side lamp. Now its tv's, videos, DVD's, computers, hair straighteners and dryers, etc.etc. with all the other comforts of home creating a fire load.
Many brigades saw this, and said a change was needed to those old standards of the 60-70's ( green draft guide 1982 what a joke ). and adopted the unpopular in England and Wales HTM84. And tried to ugrade to the current standards of the time.
Now we have risk assessment and modern standards. Knee jerk, do not make me laugh ! I think you have taken a fee in the past and now the chickens are coming home to roost !
