Sentence 3.4.6.16.(5)

Intent 1:

To supersede the requirements of Sentence 3.4.6.16.(1), which would otherwise not permit the use of locking devices, and permit electromagnetic locks on exit doors if certain conditions are met.

This is to limit the probability that:

• exit doors will not be readily openable in an emergency situation,
• persons will be unable to release the locking mechanisms on exit doors in an emergency situation, and
• persons will not be familiar with procedures for unlocking exit doors in an emergency situation,

which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.
