Safety systems

There is a wide range of fire safety systems fitted to the buildings within the University, and they vary depending on the building's age.

Older buildings may only have basic provisions for rapid escape, while newer or upgraded buildings will be fitted with sensors, sprinklers and smoke isolation systems.

Fire exits

All of our buildings are fitted with fire exits, and they can be identified by a green sign showing a person running through a door.

Fire exits must never be blocked by furniture, equipment or stored items (even temporarily).

If they are lockable, they must be able to be opened from the inside without a key.

Stairwells 

In most buildings, the entries to stairwells are fitted with smoke and fire resistant doors, giving around one hour of fire protection in a large fire. For this reason, fire doors must not be modified or drilled into.

Smoke isolation systems

Within a building, the heavy smoke from a large fire flows around much like liquid does in a flood (but up near the ceiling). 

It is extremely important that this smoke is not allowed to spread throughout the building and we do this by using smoke stop doors and fire curtains.

In modern buildings, these features are held open by electro-magnets that are turned off when the fire alarm is activated. The doors will swing shut and the curtains will lower, thus forming a barrier so the smoke does not spread.

In older buildings, smoke stop doors permanently block off corridors, and people need to push through them to move around. 

Do not wedge fire and smoke doors open

People that use wedges to prop open the doors place everyone in the building at risk, as this will allow the smoke to spread throughout the building along corridors that are necessary for escape.

For this reason, people are not permitted to hold back older style smoke-stop doors with wedges or door hooks. Staff should remove these wedges as soon as they are spotted.

Smoke detection systems

Smoke detectors are widely used, and will sound an alarm if they detect smoke.  In our more modern buildings, they will also alert Fire and Emergency NZ (FENZ).

Note: If a smoke detector starts beeping at a slow interval, it is indicating a fault that must be reported to Property Services via the Staff Service Centre.

Fire suppression systems

The most common fire suppression system in use at the University is sprinklers.

Some information about sprinklers:

• These are fitted to the ceiling and use high pressure water to cool down a room and to saturate a fire directly underneath.
• If you look closely at a sprinkler head, you will see a small capsule of liquid. This will burst when heated and allow the water to flow
• Once a sprinkler is set off, it can only be turned off at the Main Fire Panel.  Note that it is commonly thought that if one sprinkler is activated, all the other sprinklers will also activate. This is not the case — just any that are above a heat source
• Sprinkler head distance: Items must not be stored within 46cm/18 inches of a sprinkler. If you imagine a horizontal line parallel to the ceiling that is 46cm/18 inches below the sprinkler heads, then nothing must be in the area between the bottom of the sprinkler heads and the imaginary line. This is to allow an even and unobstructed spray pattern from the sprinklers when triggered to extinguish the fire.
• Some areas (mainly computer data centres) may use a gas fire suppression system. In some cases this gas will displace the oxygen within the room, so special precautions (and staff inductions) are required.
