Request

Hello, I am a surveyor and trying to find out maintenance criteria for pavement light style smoke vents. I have searched BSI online to no avail but found a LFB letter suggesting the document FSGN 506. However I cannot find such a document. I have a copy of BS7346-8 but this does not appear to directly discuss destructible pavement vents.
