Intent | Intent 1: To limit the probability that an inadequate ceiling height
of rooms or spaces [i.e. less than 2.1 m high] will lead to collision
with protrusions from ceilings, such as lighting fixtures, ceiling fans and
low door heads, which could lead to harm to persons. Intent 2: To limit the probability that an inadequate clear height
of rooms or spaces [i.e. less than 2.0 m high] will lead to collision
with protrusions from ceilings, such as lighting fixtures, ceiling fans and
low door heads, in areas used infrequently or for a limited time, and where
occupants are familiar with the space, which could lead to harm to persons.
Intent 3: To limit the probability that an inadequate ceiling height
of rooms or spaces [i.e. less than 2.1 m high] will lead to collision
with protrusions from ceilings, such as lighting fixtures, ceiling fans and
low door heads in an emergency, which could lead to delays in the evacuation
or movement of persons to a safe place, which could lead to harm to persons.
