Exposure to gas leaks can cause headaches, nausea, fatigue and breathing issues. Prolonged exposure risks serious health effects including miscarriage, brain damage or even death. Have your gas appliances inspected regularly and contact us immediately if you suspect a leak.
Gas leaks can be extremely hazardous, posing risks of asphyxiation, explosion, and carbon monoxide poisoning. Leaking natural gas contains odourless, colourless methane which can displace oxygen in enclosed spaces. Without enough oxygen, unconsciousness and death by suffocation can occur within minutes. Even small leaks over time can allow dangerous levels of methane and carbon monoxide to accumulate. Carbon monoxide is a toxic, odourless gas that impairs the blood’s ability to transport oxygen when inhaled. Preventing, detecting, and addressing gas leaks quickly is critical for health and safety.
Additionally, natural gas is highly flammable and can ignite from a spark or flame source, potentially causing devastating explosions and fires. Mild exposure leads to symptoms like headaches, dizziness, weakness, and nausea while higher concentrations can rapidly lead to unconsciousness, brain damage or death.
There are several telltale signs indicating a possible gas leak in your home. The most notable is a distinctive rotten egg smell that natural gas companies add as an odorant.

Bubbles accumulating in standing water, new patches of dying vegetation, or soot buildup on appliances can also signal a leak. Being attentive and responsive to these signs allows you to detect leaks early and prevent the health risks of asphyxiation, explosion and poisoning.
Exposure to leaking natural gas can have serious effects on human health. Exposure to leaking natural gas can have serious effects on human health. At low concentrations, symptoms may be relatively mild like headaches, dizziness, weakness, fatigue and nausea. However, accumulating levels of methane and carbon monoxide from leaks can quickly become life-threatening.
When high concentrations of natural gas displace oxygen in an enclosed space, unconsciousness and death by asphyxiation can occur within just minutes due to lack of oxygen. According to the WHO, accidental carbon monoxide poisoning kills over 1000 people each year in Australia alone. At moderate levels, carbon monoxide impairs mental function, coordination and vision, while high levels rapidly lead to disorientation, collapse, coma or death. Additionally, gas leaks that ignite can result in severe burn injuries or even death by explosion and fire. Children, pregnant women, the elderly and those with pre-existing conditions are most vulnerable to the effects of gas leaks. Additionally, gas leaks that ignite can result in severe burn injuries or even death by explosion and fire.
Carbon monoxide (CO) is an extremely dangerous byproduct of incomplete combustion from gas appliances. Installing CO detectors, having gas appliances serviced annually, and knowing the symptoms can prevent tragedy. If poisoning is suspected, leave the area immediately and call 000.
Known as the 'silent killer’, CO is a colourless, odourless gas that can quickly lead to poisoning with deadly consequences. Early symptoms of CO poisoning can include headaches, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. Early symptoms of CO poisoning can include headaches, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. Early symptoms of CO poisoning can include headaches, dizziness, weakness, upset stomach, vomiting, chest pain and confusion. Risk factors for poisoning include faulty gas appliances, blocked chimneys or flues, running engines indoors, and poor ventilation. Administering 100% oxygen can be lifesaving in severe cases of CO poisoning while long term effects may require ongoing neurological and cardiovascular monitoring.
the more recognisable symptoms of gas exposure like headaches and nausea, natural gas leaks can also manifest in other non-specific ways. General malaise, drowsiness and excessive fatigue can signal the presence of gas just as well as severe headaches or dizziness. Some people also report experiencing skin rashes, eye and throat irritation, breathing difficulties, heart palpitations, muscle weakness or an upset stomach when gas exposure occurs. Paying attention to these subtle physical cues in yourself and household members could alert you to a gas leak and allow you to act quickly to address it before more severe health effects take hold.
Elderly people or small children may seem more confused or less steady on their feet. Pets may also act anxious, fatigued or seem 'under the weather’.
the physical dangers, ongoing exposure to gas leaks can have detrimental effects on mental health. Leaking methane and carbon monoxide can impair cognitive function even at low concentrations, affecting memory, concentration, mental acuity and emotion regulation. Chronic exposure is linked to increased risks of neurological disorders like Parkinson’s disease as well as mood disorders like anxiety and depression. Leaking methane and carbon monoxide can impair cognitive function even at low concentrations, affecting memory, concentration, mental acuity and emotion regulation. Beyond the direct effects of gas exposure, the potential for devastating explosions can shatter people’s sense of safety and security in their own homes.

However, if you are experiencing ongoing mental health issues related to gas leaks, do not hesitate to seek professional support.
Children may demonstrate behavioural problems or developmental issues.
There are several steps homeowners can take to help prevent dangerous gas leaks:
Being proactive and addressing leaks swiftly by contacting a professional gas fitter can prevent carbon monoxide poisoning, fires, explosions and other health risks.
It is important for homeowners to regularly inspect their gas appliances themselves to help detect leaks early. Here are some tips when inspecting your gas appliances:
Regularly inspecting your own gas appliances helps detect leaks early, but annual checks by qualified professionals are also critical safety measures.
Installing gas detectors in your home provides an invaluable safeguard against dangerous gas leaks. Strategically place them near gas appliances, in sleeping areas, and near the floor where gases accumulate. Test detectors monthly and replace batteries annually.
Highly sensitive detectors trigger loud alarms when they detect even small amounts of methane or carbon monoxide, alerting you to a potential leak. Opt for detectors that meet Australian Standards and check the expiration date as sensors can wear out over 5-7 years. Ensure everyone in your home knows what the alarm sounds like and what to do if it goes off. Gas detectors provide round the clock monitoring and early warning against odourless and silent carbon monoxide leaks or methane buildup that can quickly become life threatening.
Familiarise yourself with the location of the main gas shut off valve for your home or building. It is usually located outside next to the gas metre but can sometimes be inside. It is usually located outside next to the gas metre but can sometimes be inside. Make sure this valve turns easily and is readily accessible. It is usually located outside next to the gas metre but can sometimes be inside.
If you smell gas or your detectors sound, evacuate immediately and shut off the gas only if it is safe to do so. Having the knowledge and ability to quickly shut off your gas supply could prove life-saving in the event of a dangerous leak. Keep a crescent wrench or gas shut off tool nearby so you can turn the valve off quickly if needed. This could prevent carbon monoxide poisoning, explosions or fires in a gas leak emergency until professionals can secure the leak site.
If you suspect a natural gas leak in your home or business, it is vital to take swift and proper action to prevent potential disaster:
Taking quick and proper action by evacuating, avoiding ignition sources and alerting emergency services can help prevent carbon monoxide poisoning, asphyxiation, explosions and fires.
If a gas leak is suspected, evacuating the area immediately is absolutely vital. The few minutes it takes to evacuate properly could save your life.
Do not waste any time - get everyone out of the building as quickly as possible. Leave all doors and windows open as you exit to allow fresh air to circulate and ventilate the area. This helps dilute the concentration of methane or carbon monoxide that may have accumulated from the leak.
