6 Safety Tips for Bushfires & BBQ Gas Bottles

Find out what to do with your BBQ gas bottle if a bushfire is approaching…

"Give it to Your Neighbour"

I live in the Blue Mountains and I once attended an RFS community meeting, as the big Lithgow fire was approaching our area.  
One of my neighbours asked “What should we do with our BBQ gas bottle?” to which the Fire Brigade Captain replied:
“Give it to your neighbour!”

While the ensuing laughter was a relief for a lot of stressed people, the real answer to the question is something that everyone who lives in a potential bushfire area should know. 
The good news is the solution is even simpler than giving it to your neighbour.

Gas Bottles Rarely Explode

First, don’t worry about the gas bottle exploding, as that would be quite unusual, as long as you keep the BBQ gas bottle upright.  
This enables the Pressure Relief Valve to operate correctly.
The Pressure Relief Valve is incorporated into the main gas valve on the bottle, as shown in the accompanying diagram.
It’s actually a valve within a valve. 
If the pressure of the gas inside the bottle increases, as the result of a fire or other heat source, the pressure relief valve releases some of the gas to relieve the pressure. 
No pressure build up means no risk of an explosion.

Aim it Safely

If there is an ignition source nearby, the venting gas may ignite, becoming a plume of flame.
The important thing is to make sure that the gas bottle is not near anything flammable and to aim the pressure relief valve safely away from any combustible materials. 
For reference, the Pressure Relief Valve points in the opposite direction from where you screw in your regulator. 
The flame plume will self-extinguish when the pressure is relieved and the pressure relief valve closes itself or when the gas bottle runs out of gas.  
As long as it was safely positioned away from anything that burns, it should not create any additional problems.

Bushfire BBQ Safety Checklist

Here is a quick checklist of what to do if a bushfire approaches:
1. Make sure the BBQ gas bottle is turned off (clockwise) at the valve on top of the bottle
2. Detach the gas bottle from the BBQ
Remember, it's reverse thread so clockwise to remove.
3. Place the gas bottle away from any flammable materials, in a well ventilated area
4. Make certain that  it remains upright at all times
5. Make sure the Pressure Relief Valve is pointed well away from anything combustible
6. Ensure that there are no gas bottles stored indoors or underneath the property

What about Home Gas Bottles?

1. Turn it off (in clockwise direction) at valve on top of the bottle
2. Leave the bottle or cylinder where it has been installed
3. Leave the bottle or cylinder in an upright position
4. Ensure it is secured to a solid structure and on a solid base to prevent it falling over, with the Pressure Relief Valve vent facing away from building. 
The vent is the protrusion, usually with a dust cover, that is opposite of where the gas line screws into the valve.
5. Remove any combustible materials surrounding the gas bottles

What NOT to do

What NOT to do with an LPG gas cylinder before evacuating:
1. Never place it inside a house or structure, as it can be a hazard to fire fighters
2. Never lay it on its side
3. Never cover it with wet material to it keep cool.  
These materials may dry out and burn, heating the bottle/cylinder
