LPG FAQs: Appliance and Installation Safety
[ Last Updated 29 May 2006 ]
Appliance Safety
Q. What Are the Biggest Dangers When Using LPG Appliances?
A. A key difficulty with LPG leakage is that it cannot disperse easily (as it is heavier than air) and tends to collect and move on the surface. In addition, many portable LPG appliances are connected directly to a cylinder. Heat transmission (generally by reflection) from the appliance to the cylinder can lead to increased pressure and explosion (especially in the case of LPG canisters).
Q. What Maintenance Does an LPG Appliance Need to Keep it Safe?
A. It is important that you ensure LPG appliances are complete and not defective. Missing or damaged parts can lead to carbon monoxide emissions that are highly dangerous. If in doubt, have it checked out.
Q. Are there any Special Safety Precautions I Should Take, When Using an LPG Appliance?
A. In addition to the above points:
- Make sure you follow the manufacturer's instructions.
- Never use the valve on the cylinder to adjust flame size or the amount of heat, use the controls provided.
- Never attempt to check for leakage with a naked flame.
- Do not try to force any fittings or connections.
- Some LPG appliances operate at high pressure directly from the cylinders, and many others must be connected through a regulator - never connect a low-pressure appliance directly to a cylinder.
- Always use and store LPG cylinders in an upright position.
- Use craftsman gasfitters or other competent people to adjust or repair your LPG appliance.
Q. What About Portable Gas Appliances?
A. Portable gas heaters such as LPG cabinet heaters and other unflued space heaters need special care:
- Test Your Connections - Cabinet Heaters: After securely connecting a new or refilled cylinder, apply soapy water to the cylinder connections and turn off the cylinder. If bubbles appear, you have a leak. Close the valve and call an LPG service agent.
- Safe Space: Always keep your heater at least 1 metre away from anything that could catch fire. Put a safety guard around your heater if you have young children in your home or if there is a lot of traffic.
- Fresh Air: Keep a window open when you use your unflued heater, to help remove heater emissions (combustion products) and to keep the air fresh and reduce condensation. Never use unflued heaters in bedrooms or bathrooms.
- Use Your Nose: If you smell gas fumes turn off your heater and cylinder immediately. Call an appliance service agent or gasfitter to have the appliance checked.
- Get a Check-Up: Before winter every year, get your heater checked and serviced by a service agent to ensure that it is in a safe condition for winter.
Note: Gas appliances designed for outdoor use should never be used indoors. This includes patio heaters, barbecues and camping cookers.
Installation Safety
Q. Whom Should I Consult Regarding the Safety of Installed LPG Systems in Motor Vehicles?
A. Consult your local authorised LPG conversion agent (see the Yellow Pages). The Land Transport Safety Authority may also be able to provide advice. (Freephone: 0800-699-000)
Q. How Safe are LPG Installations in Caravans?
A. If they are installed and used according to the Standard (NZS 5428), and maintained properly, they would be safe. Make sure ventilation and any joints and connections are checked regularly.
