Is Natural Gas Safe?

Introduction to Natural Gas

Natural gas, endorsed by various agencies such as the Environmental Protection Agency for its efficiency, often referred to as cooking gas, is a fossil fuel commonly utilised in homes for tasks such as cooking, heating with gas heaters, and food preparation on gas stoves. It is composed primarily of methane and, considering the impact on climate change, is piped directly into homes and businesses via an extensive underground network of pipelines.

Compared to other fossil fuels like coal and oil gas, natural gas paves the way towards renewable energy with its cleaner combustion, underpinning environmental protection as noted by scientist pse healthy Energy with lower greenhouse gas emissions and releasing fewer pollutants into the air when used effectively.

Natural gas is a significant energy source in the United States, accounting for approximately 24% of the country’s energy consumption.

The Chemical Composition and Properties of Natural Gas

Extracted from a gas well and shale gas formations through processes like hydraulic fracturing, and conveyed through an extensive gas pipeline network, natural gas burned is acknowledged as a clean energy source, primarily composed of methane. During the process of burning natural gas, especially types with 70-90% methane content, it discharges carbon dioxide and water vapour into atmosphere.

Trace amounts of nitrogen, carbon dioxide, oxygen, and hydrogen sulphide that have been produced may also be present.

Key properties for the safe usage of natural gas are:

• Natural gas is lighter than air, which allows it to rise and accumulate near ceilings in the event of a leak.
• As natural gas is odourless, odorants like mercaptans are added to provide a distinctive rotten egg smell for leak detection purposes.
• Produces cleaner energy with fewer hazardous air pollutants than other fossil fuels when burned.
• Non-toxic, but at higher concentrations, measured in parts per million, can displace oxygen causing a suffocation hazard in confined spaces.

Considering the dangers natural gas poses, such as flammability and asphyxiation hazards, upholding protocols for safe natural gas use is essential.

Detecting Natural Gas Leaks

Knowing how to swiftly detect gas leaks in your appliances and fixtures is crucial for natural gas safety.

If you detect a smell reminiscent of rotten eggs, it’s a potential indicator of a gas leak in your home. Other signs of a leak include:

• Hissing, whistling or roaring sounds coming from gas appliances or pipes
• Dirt spraying from the ground or bubbling in wet areas near gas lines
• Flames coming from the ground or burning above gas appliances
• Unusual odours near gas equipment
• Dead plants or grass in otherwise moist areas near gas lines

Smaller leaks, especially those involving leaking gas in a pipeline, may not be noticeable by smell alone. Gas can accumulate undetected over time in enclosed spaces like basements, leading to risk of fire, explosion or carbon monoxide poisoning.

Annual inspections by a licensed gasfitter with gas detectors are critical in identifying elusive leaks before they result in hazardous air pollution or adverse health effects. In case of uncertainty, contact your local gas utilities provider or an authorised technician to inspect your gas infrastructure for leaks before any excavation begins.

Health and Safety Risks of Natural Gas Leaks

Natural gas leaks pose significant health and safety hazards, including an increased risk of fire and explosion, and prolonged exposure to leaked gas can lead to serious health concerns.

Inhaling unburned natural gas can lead to dizziness, nausea, and severe cases of loss of consciousness or asphyxiation. Leaked gas in concentrations ranging from 5-15% can ignite or cause symptoms of poisoning in humans.

Preventing and Preparing for Natural Gas Leaks

There are several steps homeowners can take to help prevent natural gas leaks and prepare in case one occurs:

Prevention

• Annual servicing of gas appliances by a qualified technician is vital to check for leaks, repair damaged parts, and guarantee optimal operation.
• Visually inspect pipes and fittings regularly for signs of corrosion or damage. Contact your local gas association or company if any issues are found.
• Ensure clear surroundings around your gas meter and appliances to maintain proper ventilation.
• Avoid excessive pressure on pipes that can lead to cracks or loosened joints.

Preparation

• Install detectors to monitor levels of carbon monoxide and LP gas, which alert occupants to significant leakages when using natural gas appliances.
• Make an emergency plan so all household members know how to respond to the smell of gas.
• Keep the 24-hour gas company emergency number and a licenced plumber’s number handy.
• Learn how to use the shutoff valve to turn off your meter and individual appliances in case immediate shutdown is needed.
• Never search for a leak with an open flame. Use a flashlight if lights must stay off.
• Keep a window open for ventilation when performing any work on gas appliances.

Prioritising gas safety and thorough preparedness enables residents to swiftly and securely respond to gas leaks. Know the warning signs, have a response plan, and call a professional anytime a leak is suspected.

What to Do in Case of a Suspected Gas Leak

If you suspect a gas leak in your home, it is crucial to act quickly and safely to find out the source:

1. Evacuate the area immediately - get everyone out of the house or building and move a safe distance away. Do not operate any electrical devices or switches as sparks could ignite and leak your gas.
2. Avoid using any flames or sparking devices. Do not smoke, light matches, use lighters, turn on appliances, or do anything that could cause a spark.
3. If circumstances allow, engage the shutoff procedure off main gas supply valve outside your residence. Use an adjustable wrench and give the valve a quarter turn in either direction to detect gas interruptions. This will shut off gas flow into your home.
4. Contact the gas company’s 24-hour emergency number and ensure the gas is turned off. Never resume use of gas appliances until inspected by a qualified technician.
5. If you can’t reach the gas company, call emergency services on 000. Gas leaks can quickly become dangerous so don’t delay seeking help.
6. Do not switch lights or electronics on or off, as this can produce sparks. Use a flashlight if you need light.
7. Open doors and windows to ventilate the area.
8. Warn neighbours who may be affected by the escaping gas. Make them aware of the danger.

Evacuating promptly, avoiding ignition sources, and shutting off the main gas valve in your home are key measures to ensure safe usage and mitigate gas leak hazards. Never assume a leak will take care of itself - always call the gas company or emergency services any time a leak is suspected.
