2. of a height to protect people from accidentally falling from the level; and
3. constructed to prevent people falling through the barrier; and
4. capable of restricting the passage of children; and
5. of a strength and rigidity to withstand the foreseeable impact of people and where appropriate, the static pressure or people pressing against it.

1. function or use of the structure; and
2. size of the structure; and
3. distance of travel to an exit.

To facilitate evacuation from a temporary structure suitable signs or other means of identification must, to the degree necessary—

1. be provided to identify the location of exits; and

(2) Ventilation must be provided to the degree necessary, to a level appropriate to the function or use of a temporary structure.

Electrical services must be installed to the degree necessary, to provide a level of safety appropriate to the environment and function or use of a temporary structure by the occupants.

Where provided for a temporary structure, a heating appliance and its associated components must be installed to the degree necessary—

1. to withstand the temperatures likely to be generated by the appliance; and
2. so that it does not raise the temperature of any structural element to a level that would adversely affect the element’s physical or mechanical properties or function; and
3. so that hot products of combustion will not—
   1. escape through the walls of the associated components; and
   2. discharge to a position that will cause fire to spread to nearby combustible materials or allow smoke to penetrate the temporary structure; and
4. to reduce the likelihood of fire and harmful emissions spreading beyond the appliance.

A temporary structure of tiered seating must be designed and constructed to the degree necessary, to provide for the safety of occupants and orderly means of evacuation in an emergency.
