I think, It’s not just a matter of just agreeing or disagreeing about…, any way that's what I have found in terms of legislation just to state some:
1. Offices, Shops and Railway Premises Act 1963
2. Private Places of Entertainment Act 1967
3. Factories Act 1971
4. Health and Safety at Work Act 1974
5. Fire Certificates (Special Premises) regulations 1976
6. Fire Precautions (Workplace) Regulations 1997
Etc…
Thus, what about dwellings? Why is not an obligation by the law to have means of fire protection for dwellings, even they are private?
Also, in terms of standard, why the levels of protections L1 to L5 in addition to M and P...etc, are not applicable to dwellings accordingly... including houses with their different sizes even if they are privates?
Dwellings are covered separately with less tedious requirements in BS5839 part: 6. through what they called the grades from A to F…, dwellings too are multiple occupancies when it comes to the number of people living in, or coming in and out or invited some times so what’s the difference?
In the common sense, it’s the people’s lives that matter first isn’t it? What ever the sort of buildings?
