9.8.8.3.(2)

Intent 1:

To limit the probability that guards will not be high enough to provide reasonable fall protection, which could lead to:

• persons falling, or
• persons falling in an emergency, which could lead to delays in the evacuation or movement of persons to a safe place.

This is to limit the probability of harm to persons.

Intent 2:

To supersede the guard height requirement stated in Sentence (1), in cases where the risk of falls and injury is reduced because occupants are likely to be familiar with their surroundings.
