Range Statement

This section specifies work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included. Bold italicised wording, if used in the performance criteria, is detailed below.

Fire suppression solutions must include two of the following:

chemical systems

detection and warning systems

special hazard foam systems

special hazard gaseous agent systems

water-based deluge or pre-action sprinkler systems.

Risk profile of the building or facility will reflect its use and must include details of:

users of and visitors to the site and the need to protect them

value of the equipment, facility or goods stored

susceptibility of the stored goods to water or other forms of damage resulting from the use of different types of system.

Special hazard standards must include at least one standard from the following list:

relevant Australian standards, including:

AS ISO 14520.1 Gaseous fire-extinguishing systems - Physical properties and system design - General requirements

AS4487 Condensed aerosol fire extinguishing systems - Requirements for system design, installation and commissioning and test methods for components

United States National Fire Protection Association (NFPA) standards, including:

NFPA 2001 Clean Agent Fire Extinguishing Systems

NFPA 11 Low, Medium and High Expansion Foam Systems

NFPA 11A Medium and High Expansion Foam Systems

NFPA 13 The Installation of Sprinkler Systems

NFPA 16 Deluge Foam-Water Sprinkler and Foam-Water Spray Systems.

Fire detection and occupant warning solutions must include:

fire alarms

fire gas detectors

flame detectors

heat-sensing detectors

smoke-sensing detectors.

File naming must include:

accurate naming and filing of drawings, including formal document control and amendments:

history

transmittal notices

naming conventions for design drawings and drawing registers.

Interactions between multiple systems on a complex site must be analysed to:

ensure most effective selection of systems to protect different assets

maximise effectiveness of systems

maximise efficiency of installation process.

Efficient and workable layout and location must consider:

access constraints

aesthetic requirements

conflict with other services

efficiencies to facilitate work on site

installation problems

penetrations

reduction of labour costing

work health and safety risks.

System components must include:

brackets

discharge nozzles

fire panels

pipework

system valves

zone valves.

Calculations that relate to the special hazard fire systems must include:

foam system calculations.

gaseous system calculations

hydraulic calculations to assess pressure requirements and confirm pipe sizes

water-spray system calculations.

Infrastructure for special hazard fire system solutions must include:

delivery systems for the suppression agent

pipework

storage containers

tanks.

Negotiated change must include one made due to:

impact on cost-effectiveness

impact on installation risks and constraints

non-compliance with applicable legislation, codes and standards.

Fittings and components must include:

control valves

elbows

hangers

pipe fabrication methods and constraints

pumps

sprinkler heads

tanks

tees.
