Recommendations for when to use a Fire Extinguisher
The New Zealand Fire Service recommend that a Fire Extinguisher should only be used in the following circumstances.
After everyone has been evacuated and accounted for at a safe meeting place.
After the Fire Service has been called.
When it is safe to do so considering the size and location of the fire.
Access to the fire is unrestricted and a safe retreat is possible at all times.
Remember life is more important than property, don't put yourself or others at risk.
Only when everyone is outside and the Fire Service has been called, and only if it is contained and you can safely escape.
