Perhaps the answer to this dilema of the fire door is to have a demonstation before a fire drill? 

So after your next fire drill, everyone will have evacuated the building and come to the assembly point, so have the Fire Marshalls check if those doors with the ceramic tube or glass tube have been smashed to use the door. 

I would personally reccomend having an electronic tag on the fire door, to show if the door is used, not in the case of fire, but in the case of burglary, plus a trip switch would easily show on a fire evacuation panel that those fire doors have been activated (opened) during an evacuation or burglary. 

ncann88 - Yes Redlam Bolt type door furniture is acceptable, but it's use must for part of a fire risk assessment.

They are acceptable when less than 60 members of staff are expected to use them from a low risk environment. I have seen them used on final exits from factories to deter the final exit being used for other purposes (smoking for example)

But for high fire risk areas where a rapid developing fire is expected, where there's  60+ people, where lots of the public would be expected to use that exit, or when vulnerable people - including children - are also expected to use it, I would rather an alternative solution be found

I audited a very smart hotel in Londons West End (currently £450 a night for the cheapest room). There was a central accomodation staircase and two external staircases from each floor. Access to the external escape routes was by redlam bolt fixings with glass tubes to prevent smokers leaving and prostitutes being smuggled in  

98% of guests were from overseas and the majority of then had poor English language skills. After a long battle, the Redlams were replaced with green break glass overrides 

In the example given where children are likly to pass through the exit, I would be very anxious that a childrens sleeping area has Redlam bolts as it would be very difficult to justify them
