When does the requirement for operable windows in an RC home no longer apply?

The requirement for operable windows in a residential care home no longer applies when there is an operable window that can be used as an emergency exit available. This is based on safety regulations which prioritize having emergency exits in case of fire or other emergencies. If a room has a window that can serve this function, it fulfills a critical safety need, thus removing the necessity for additional operable windows.

Regarding the other options, they do not fulfill the same safety criteria. A ground floor location may offer other levels of safety but does not inherently satisfy the requirement for emergency escape routes. Similarly, just having a fire escape does not negate the need for operable windows that serve as exits in every room. Lastly, the preferences of residents for no windows do not align with safety regulations that focus on operational needs and emergency preparedness rather than personal choice.
