As the chill of winter approaches and load-shedding remains an ever-present threat, many households are turning to gas heaters as a reliable source of warmth. However, before firing up your heater for the first time this winter season, it is essential to ensure that your gas appliances are safe and in proper working order. Michael van Niekerk, CEO of ASP Fire, shares important safety advice to help households use gas heaters responsibly and avoid common hazards.

“Gas is a highly efficient and effective energy source, but it must be handled with care. Improper use or poor maintenance can result in serious incidents, including gas leaks and explosions. Safety always comes first,” says van Niekerk.
When reconnecting your gas heater after it has been in storage, begin by checking the connection between the gas appliance and the cylinder. “Always ensure the connection is gas-tight,” advises van Niekerk. “If there is a smell of gas, it is a clear indication of a leak. Disconnect it immediately and check that everything is secure.”
Gas appliances are fitted with rubber or fibre washers that seal the connection and prevent leaks. Over time, these washers can deteriorate, especially when stored in fluctuating temperatures. “Always inspect the seals for cracks or wear, and replace them if necessary,” adds van Niekerk.
Cleanliness is also a critical safety measure. Dust and debris can clog gas jets, leading to inefficient combustion or dangerous flare-ups. Before connecting the heater to the cylinder, inspect and clean the jets thoroughly.
For older models without automatic ignition, lighting the appliance should be done with care. “Always light your match or lighter first and hold it to the burner before opening the gas. This prevents gas from accumulating in the air, which could cause a flash fire when lit,” warns van Niekerk.

Ventilation is another essential aspect of gas heater safety. No matter how cold it gets, a window should always be left slightly open in the room where a gas appliance is in use. “Adequate airflow ensures that oxygen levels remain safe and prevents the build-up of carbon monoxide, a silent and potentially lethal gas,” says van Niekerk.
At the end of the day, do not forget to turn off the gas at the source. The LPG cylinder valve only needs to be turned one-and-a-half times to open fully, and it must be closed securely when the appliance is not in use. The cylinder itself should be placed on a firm, level surface, away from foot traffic and potential hazards.
Proper storage and transportation of gas cylinders are vital. Cylinders should always be kept upright, fitted with a protective cap, and secured in a well-ventilated, demarcated area. Never expose them to extreme heat or flames. “Gas expands when heated, increasing pressure inside the cylinder. If the cylinder is exposed to temperatures above its rated maximum, it can rupture or explode,” explains van Niekerk.
In the event of a gas leak, the smell of gas, thanks to the odourant added to LPG, should alert users immediately. For added safety, van Niekerk recommends installing a gas detector, particularly in homes where gas is used regularly.
Lastly, while no special certification is needed for homeowners to operate domestic gas appliances, any installation or modification must be carried out by a qualified professional. “Certified installation is not just a regulatory requirement but a fundamental safety measure. DIY gas setups can be incredibly dangerous,” stresses van Niekerk.
As winter approaches, now is the perfect time to carry out safety checks on all your gas equipment. By following these expert guidelines and staying informed, households can enjoy the warmth and comfort of gas heating without unnecessary risks.
