Installation Of Sprinkler Systems

Fully automatic fire sprinkler systems are widely regarded as the most effective method of controlling a fire.

Wormald designs, installs and commissions reliable, cost-effective sprinkler systems by carefully analysing a building and its contents in terms of occupancy, operation and fire risk.

These systems are engineered to comply with the relevant New Zealand and international standards, using the latest in fire protection technology.

Sprinkler systems automatically detect a fire, transmit an alarm and control or extinguish the fire. They are located in places where people cannot always be present and operate only as needed in the immediate vicinity of the fire.

They have important life safety connotations, and can prevent fires from reaching destructive proportions, which may mean the difference between a minor interruption and a prolonged permanent shutdown.

Automatic fire sprinklers provide a significant level of protection for the occupants of a building together with protection of the environment by minimising the effects that a major structural fire could have. Sprinklers also safeguard against loss of product, equipment and building contents in general as well as minimising disruption to normal operations.

How Sprinkler Systems Work

A typical sprinkler system consists essentially of a piping network, connected to a permanent water supply and control valves feeding automatic sprinklers spaced regularly throughout the protected premises, incorporating local and fire department service alarms.

Convected heat from a fire causes operation of one or more thermally sensitive sprinklers, thereby permitting water to be discharged directly over the fire affected area.

Sprinkler System Design

Each sprinkler system is custom designed to ensure that:

  • The occupancy of the risk to be protected is identified according to the amount and combustibility of contents, and the likely fire intensity - in order to determine the volume of water discharge necessary for fire control.

  • The water distribution system (i.e. the pipework arrangement) is designed so that it is capable of discharging water to any part of the area at the specific discharge volume applicable to the occupancy class involved.

  • The water supply is capable of providing the required dischange at minimum pressures for minimum durations.

 

Hazard Clasifications

Based on sprinkler performance records that the majority of occupancies fall into four groups, namely:

  • Extra Light Hazard - Non industrial where amount and combustibility of contents is low.

  • Ordinary Hazards - Processing and handling of mainly ordinary combustible materials unlikely to develop intensely burning fires in the initial stages.

  • Extra High Hazards - Goods storage with abnormal fire loads likely to produce exceptionally intense fires with high rates of heat release and with high storage heights.

  • Process hazards – Extra hazardous, when rapidly and intensely burning fires are likely to develop.

 

Water Spray Systems

Water Spray Systems: Designed to direct water to entirely impinge onto the hazard surface in applications such as transformers, turbines and flammable/combustible liquid hazards.
