PIR in central staircase

[Guest Robert John]

Hi, apologies if this isn't the correct thread to ask this question but it's the only one I can find.  We recently had an external Environmental audit to identify areas of improvement for our organisation to improve our environmental efficiency.  One of the actions that our auditors have give us is to change all of the lighting in our stairwells to PIRs, however one of our board has questioned if this is legal as they are stairwells? 

I have done some digging around and have not been able to find any information to either confirm or deny if this is compliant with legislation.  

Can anyone help?

 

Many thanks

 

Robert

Yes you can as long as the PIR locations and activation times are such it's not possible to be navigating a flight before they lights activate nor them cut out before you've finished.

Many buildings have these.
