In HMFC it would have been so easy... get the Security inspectors in - you could always rely on them to come up with the opposite recommendation to the firemen! As I recall, the Fire Jobsworths would come round annually, telling us how all these entrances etc needed to be easily openable and not lockable; the following week, the Security Jobsworths would come round telling us that everything had to be as locked as a locked thing in locked land... how I loved that trivia!
