Sentence 2.7.2.1.(2)

Intent 1:

To exempt revolving doors from the once a month testing requirements of Sentence 2.7.2.1.(1) on the basis that:

• these doors are generally frequently used [as main entrances and in primary egress routes] and a deficiency would be expected to be readily corrected, and
• a yearly check is required.

This [the yearly check] is to limit the probability that the doors will not operate properly in an emergency situation, which could lead to delays in evacuation or movement to a safe place, which could lead to harm to persons.
