5.2.8.5 Toilet facilities and changing rooms

McN41R

For such a small paragraph in BS5266, I fend many questions with respect to when you must provide emergency lighting and when it should be supported with emergency lighting calculations.

I assume I am not alone in this, so I thought I would share my interpretation of the requirements. I could not find any information on when you would consider a multi-closet facility to have borrowed light, the assumption at the end is unfounded and my interpretation only. Comments appreciated.

[post comment] The original intend of this post was to find if this table helped simplify the process of determining the requirements for emergency lighting in bathrooms etc. The intent was not to discuss the design process, nor the question of what borrowed light is, or any other standard. 

Unfortunately, I am unable to delete the topic or close it.

Note: closet, wall and doors must allow borrowed light. Using standard partition sizes and typical minimum ceiling height this would include 300mm above, and 100mm below. Where closet cannot be provided with borrowed light then emergency lighting per closet should be provided.

    Meanwhile some clever git installed presence detectors to turn the normal lighting on and off without giving people time to do what they need to do.

    yep, that is a pet peeve…. And for best comic effect put the sensor pointing at the entrance, but the light over the cubicle. Then the user has to get up in mid production and move to the door and wave arms or something to get the lights back on.

    Or take a head torch.

    Mike,

    Leigh, I don't believe that the standard applies to areas that have public access. See extract:

    I also don't believe that hotel rooms should be provided with emergency lighting (although many do), typically referring to Section 5 in BS 5266.

    If you have particular clause that would suggest otherwise, I would appreciate the information.

    Lyledunn, upon reflection I concur that a bathroom or an ensuite facility within a hotel room would not be provided with emergency lighting, irrespective of size. I will amend table to reflect.

    However, all facilities exceeding 8m2 need to be provided with emergency lighting, even if for single use, even if it has borrowed light (excluding, hotel bedroom facilities).

    Happy to relook if you believe this should be interpreted differently.

    So if you are in the bath or shower covered in shampoo and the lights go out, as the fire alarm sounds, and you are plunged into darkness will that cause a hazard and delay escape?

    I have concurred that using the IET forum is a complete waste of time and the professionalism shown here is akin to Facebook standard.

    It would be great to part of a strong professional group, unfortunately this is not it.

    @Zoomup, Sorry, I don't believe that your posts are professional in anyway.

    Don't be sorry. Just ask yourself, what is the prime purpose of emergency escape lighting? Look at the wider picture.
