TAS Part I18 Temporary structures
Introduction to this Part
This Part contains additional requirements for temporary structures.
Performance Requirements
TAS I18P2 to TAS I18P16 only apply to a temporary structure that—
- is used by the public as a place of assembly as described in the Public Health Act 1997; and
- is a temporary structure as described in the Building Act 2016.
Application of Part
A temporary structure must, to the degree necessary, be capable of sustaining at an acceptable level of safety and serviceability the most adverse combination of loads and other actions to which it may reasonably be expected to be subjected.
Safety and serviceability
The material used in a temporary structure must, to the degree necessary, be capable of resisting the spread of fire to limit the generation of smoke and heat, and any toxic gases likely to be produced.
Resistance to the spread of fire
- walking surfaces with safe gradients; and
- stairways and ramps with slip-resistant walking surfaces; and
- suitable handrails where necessary to assist and provide stability to people using a stairway or ramp.
Access
- travel distances to exits; and
- number, mobility and other characteristics of the occupants; and
- function or use of the structure.
- number, mobility and other characteristics of the occupants; and
- function or use of the structure.
Exits
Where a person could fall 1 m or more, due to a sudden change of level within or associated with a temporary structure, a barrier must to the degree necessary, be provided which must be—
- continuous and extend for the full extent of the hazard; and
- of a height to protect people from accidentally falling from the level; and
- constructed to prevent people falling through the barrier; and
- capable of restricting the passage of children; and
- of a strength and rigidity to withstand the foreseeable impact of people and where appropriate, the static pressure or people pressing against it.
Fall prevention
A level of illumination for safe evacuation from a temporary structure in an emergency must be provided, to the degree necessary, appropriate to the—
- function or use of the structure; and
- size of the structure; and
- distance of travel to an exit.
Lighting
To facilitate evacuation from a temporary structure suitable signs or other means of identification must, to the degree necessary—
Identification of exits
Fire equipment must be installed in a temporary structure to the degree necessary, to allow the occupants to undertake initial attack on a fire appropriate to the—
- function or use of the structure; and
- fire hazard.
Fire-fighting equipment
Sanitary facilities for personal hygiene must be provided in a convenient location associated with a temporary structure, to the degree necessary, appropriate to the—
- function or use of the structure; and
- number and gender of the occupants; and
- disability or other particular needs of the occupants.
Sanitary facilities
Artificial lighting
Ventilation
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.
Electrical services
Where provided for a temporary structure, a heating appliance and its associated components must be installed to the degree necessary—
- to withstand the temperatures likely to be generated by the appliance; and
- 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
- so that hot products of combustion will not—
- escape through the walls of the associated components; and
- discharge to a position that will cause fire to spread to nearby combustible materials or allow smoke to penetrate the temporary structure; and
- to reduce the likelihood of fire and harmful emissions spreading beyond the appliance.
Heating appliances
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.
Tiered seating
A temporary structure must, to the degree necessary, be a safe and hazard free environment for the people using the structure.
Safe environment
