Understanding Gas Leaks and Their Dangers

A natural gas leak, where combustible substances escape from building pipes, valves, or fittings, is hazardous. Providers add a distinct scent (mercaptan) to the normally odourless gas, facilitating quick detection.

There is no understating the serious threats posed by a gas leak, which include:

  • Risk of fire or explosion, since gas can ignite from a spark or open flame
  • Carbon monoxide poisoning from running appliances in poorly ventilated areas, detected by carbon monoxide detectors, poses health risks
  • Suffocation due to oxygen displacement

Gas leaks, whether in homes, businesses, or factories, necessitate preparedness for various scenarios. The most common causes include faulty appliances, damaged pipes or valves, improper installations, natural disasters, and construction accidents.

Early detection of gas leaks is possible by staying alert to signs such as hissing sounds, a rotten egg smell, visible vapour or mist, dead plants near gas lines, and discoloured appliance flames.

Gas safety requires adherence to national regulations and proactive inspections for leaks due to their potential danger. Awareness of gas leak prevention and strategies such as certified appliance installation is crucial for risk mitigation.

How to Detect Gas Leaks

By Smell

In learning to use natural gas safely, measures that help prevent gas leaks include the application of odourants like mercaptan, which has a distinctive 'rotten egg’ odour, by gas providers. If you detect this smell in or around your house, take immediate action as it may signal a potential gas leak.

By Sound

Listen for hissing sounds from gas pipes or appliances, as these may indicate escaping gas and point to a leak.


Be vigilant for signs like unexpected vapour or bubbles in standing water, lifeless plants indicating issues with your gas lines, or soil upheaval possibly from carbon dioxide near gas infrastructure, hinting at possible escape points. Your gas stove flames changing colour can indicate improper flow of gas, which warrants immediate attention.

If You Suspect a Gas Leak

Should you suspect gas escape within your premises, maintain composure and adhere to these immediate safety protocols in your home:

  1. The first step is to leave your home immediately and journey to a safe distance away; it’s essential to do so quickly if red flags of a gas incident are observed. Do not operate any devices or appliances that could generate sparks.
  2. If safe, turn off the gas supply at the main valve using an adjustable wrench with a quarter turn clockwise to prevent further leakage.
  3. To ensure safety, ventilate the area by opening all doors and windows to dissipate the gas, and call a technician to shut off the supply.
  4. If you have a national gas emergency, dial your local emergency personnel on 000 and use the gas emergency number, such as Epping Plumbing’s hotline at 1300 349 338. For immediate action at home call gas company if necessary.
  5. Refrain from returning inside and if in doubt of safety in your home call professional services until you receive an all-clear directive. If uncertain, leave the area immediately, call the authorities, and seek guidance. Be wary of symptoms pointing to carbon monoxide CO leaks, as your body may experience throbbing headaches, vertigo, chest discomfort, and nausea.

Promptly address gas leaks by calling certified technicians to resolve any issues through their expertise. If you smell gas or suspect a leak, evacuate immediately and contact certified gas technicians to inspect and repair any damages, ensuring safety before returning.

Preventing Gas Leaks

Grasping how to recognise the signs gas issues present demands a thorough approach regarding safety measures and device upkeep:

Proper Installation and Maintenance

Ensuring gas leaks are avoided is critical, especially by engaging accredited specialists for appliance and line installation. Establish regular maintenance to make sure your gas pipes, valves, and appliances remain in pristine condition, free of deterioration.

Have service personnel rigorously check for leaks during installation and hookup of gas systems. Be vigilant and replace old gas fittings when needed to avoid cracks and damage.

Gas Leak Detection Systems

Consider acquiring a gas detection system like reliable portable leak detectors that trigger an alarm and allow you to monitor gas levels when high concentrations are present. Regularly perform gas leak tests on detectors to ensure your environment remains safe, by testing their batteries and functionality. Have a gas safe professional check calibration annually.

Ventilation and Safe Usage

Enhance home security by ensuring that areas with your gas appliances, such as your furnace and water heaters, have ample airflow to prevent dangerous carbon monoxide accumulation. Confirm that maintenance personnel check that vents are clear to ensure safety. Use appliances only as intended by manufacturers.

Emergency Preparedness

Create an emergency plan with detailed contact information for aid organisations, your gas supplier, and expert technicians to safeguard your household. Ensure residents know how to identify gas leaks, operate the shutoff valve, and evacuate urgently if a leak is suspected.

Executing practical measures and observing tips prevent gas mishaps are essential for averting hazardous outcomes. Nonetheless, if faced with such a scenario, follow safety tips, exit immediately, and contact Epping Plumbing’s emergency service on 1300 349 338.

Gas Safety Education

Educate Yourself and Others

Recognising that natural gas leaks may go undetected is crucial for robust gas fortification. Have an emergency plan with escape routes and meeting points that anyone can take promptly in a crisis. Keep emergency numbers for Epping Plumbing, your gas provider, and first responders near phones.

Confirm that you, along with your family, are well-informed about leakage signs, skilled in emergency procedures, and conversant with guiding first responders to the main gas valve.

In your workplace, property custodians must ensure regular provision of gas safety instructions to protect your property and employees. Topics may include:

  • how to recognise that gas leaks can manifest as rotten egg smells or hissing noises
  • Proper safety procedures for an orderly and effective evacuation
  • Where gas supply shutoff valves are and how to turn off gas using these crucial safety mechanisms
  • Who to contact in a gas leak emergency

Epping Plumbing also offers sessions to explore a potential gas leak your residence or commercial enterprise may encounter, amounting to more than just an inconvenience. Our technicians can demonstrate effective gas detection methods your establishment might require, respond to usage inquiries, and confirm that correct protocols are active.

Conduct Informal Leak Tests

Diligence in which you can find issues by examining your gas meter and associated fixtures for leaks using simple soapy water tests remains the remit of your own vigilance. Similarly, commercial space managers may coordinate custom leak scouting appraisals, leveraging personal initiative for ongoing protections.

Keep an eye out for bubbles, which can indicate escaping gas.

Educating oneself about gas hazards and countermeasures facilitates a proactive stance towards prevention and inspection. Yet, in the event gas leak symptoms or unusual sounds manifest, leave the premises without delay and alert Epping Plumbing on 1300 349 338 - avoid trivialising the occurrence.
