1. OS3


OS3 Safety in Use



Intent 1:

To limit the probability that persons will enter an excessively long dead-end portion of a corridor during an emergency situation and be prevented from retracing their steps as a result of crowd pressure or untenable conditions, which could lead to delays in the evacuation or movement of persons to a safe place, which could lead to harm to persons.

Intent 2:

To exempt dead-end corridors entirely within suites from the maximum 6-m length requirement stated in the second part of the Sentence, on the basis that the occupants are familiar with the suite arrangement and are expected to make appropriate decisions in an emergency.

Intent 3:

To direct Code users to Sentence to which this requirement [length of dead-end corridors] is an exception.
