How to Prepare for Gas Geysers (Underground Gas Release): A Comprehensive Safety Guide

Underground gas releases, sometimes dramatically referred to as “gas geysers,” represent a rare but potentially catastrophic hazard that can occur in both rural and urban environments. These sudden, powerful eruptions of underground gases can pose significant threats to property and human safety, often with little warning. According to the U.S. Pipeline and Hazardous Materials Safety Administration (PHMSA), there are approximately 300,000 miles of gas transmission pipelines and over 2.2 million miles of gas distribution lines nationwide, creating numerous potential points for underground gas releases.

At Batten Home Security, we’ve observed that most homeowners remain largely unaware of the risks associated with underground gas infrastructure until an incident occurs in their area. This guide aims to bridge that knowledge gap by providing practical, actionable information to help you recognize, prepare for, and respond to underground gas release emergencies.

Understanding Underground Gas Releases: Causes and Risks

Underground gas releases occur when pressurized natural gas, methane, or other gases escape from their containment systems beneath the earth’s surface. Unlike controlled releases, these events can be sudden and violent, sometimes creating geyser-like eruptions of gas, soil, and debris. The U.S. Department of Transportation reports that between 2010 and 2020, there were over 1,800 significant gas pipeline incidents resulting in 193 fatalities, 767 injuries, and over $3.1 billion in damages. These statistics underscore the importance of preparation, especially for those living near gas infrastructure.

The primary causes of underground gas releases include:

Pipeline corrosion or material failure
Excavation damage (the leading cause, accounting for nearly 25% of all incidents)
Natural disasters like earthquakes or landslides
Ground shifting or soil subsidence
Improper installation or maintenance of gas infrastructure
Methane releases from landfills or natural deposits

Identifying Potential Gas Geyser Risks in Your Area

The first step in preparation is understanding your specific risk level. Most homeowners we work with are surprised to learn they may live near underground gas infrastructure without being fully aware of its presence or potential hazards. According to the National Pipeline Mapping System, approximately 65% of Americans live within the potential impact radius of a gas transmission pipeline, yet many remain unaware of this proximity.

Research Your Property and Surrounding Area

Check the National Pipeline Mapping System (NPMS): Visit the NPMS Public Viewer to identify major gas transmission pipelines near your property.
Contact local utility companies: Request information about underground gas lines servicing your neighborhood.
Review property documents: Easement records and property surveys often contain information about underground utilities.
Consult with local emergency management: Many counties maintain hazard vulnerability assessments that include information about gas infrastructure risks.
Research historical incidents: Look into whether your area has experienced gas-related emergencies in the past.

Recognize Warning Signs of Potential Underground Gas Problems

Based on data from the Pipeline and Hazardous Materials Safety Administration, early detection of gas leaks can reduce the risk of catastrophic failure by up to 70%. Many of the families we assist in emergency planning are unaware of the subtle indicators that might precede a more serious gas release event.

Unusual odors: Natural gas is typically odorized with mercaptan, creating a distinctive “rotten egg” smell.
Vegetation changes: Dead or discolored vegetation in a specific pattern or line when surrounding plants appear healthy.
Unusual sounds: Hissing, whistling, or roaring sounds coming from the ground or gas appliance connections.
Bubbling in standing water: Gas rising through puddles, ponds, or wet areas.
Dirt or debris being blown into the air: Small “blowouts” can precede larger releases.
Ground movement: Unusual soil subsidence or heaving in a localized area.
Frost-like ground appearance: In cold weather, escaping gas can cause moisture in the soil to freeze, creating unusual frost patterns.

Creating a Gas Emergency Preparedness Plan

According to the Federal Emergency Management Agency (FEMA), households with emergency plans are significantly more likely to survive disasters with fewer injuries and less property damage. Yet our experience shows that while many families prepare for common emergencies like fires or severe weather, specific preparation for gas-related emergencies is often overlooked. A comprehensive gas emergency plan should address both prevention and response.

Essential Components of Your Gas Emergency Plan

Emergency contact information: Keep your gas company’s emergency number, 911, and poison control (1-800-222-1222) readily accessible.
Gas shut-off procedures: Document the location of your home’s main gas shut-off valve and ensure family members know how to use it.
Evacuation routes: Plan multiple escape paths from your property, considering that some routes might be compromised during a gas emergency.
Meeting locations: Designate primary and secondary meeting points at safe distances from your home.
Communication plan: Establish how family members will contact each other if separated during an evacuation.
Special needs considerations: Account for mobility limitations, medical requirements, and pet evacuation.

Gas Emergency Supply Kit

In addition to your standard emergency supplies, we typically recommend homeowners living near gas infrastructure maintain specialized items that can be particularly useful during gas-related emergencies. According to the American Red Cross, emergency kits should be checked and refreshed at least twice yearly.

Gas shut-off wrench: A non-sparking, adjustable wrench specifically for your gas meter.
Battery-powered carbon monoxide and natural gas detectors: For use during power outages.
Fire extinguishers: Multiple ABC-rated extinguishers placed strategically throughout your home.
Respirator masks: N95 or higher-rated masks to protect against airborne particles.
Emergency blankets: Compact, metallized blankets for warmth if utilities are compromised.
Bottled water and non-perishable food: Sufficient for at least 72 hours per person.
Battery-powered radio: To receive emergency broadcasts during power outages.
Flashlights and extra batteries: Never use matches or lighters during a suspected gas leak.

Installing and Maintaining Gas Detection Systems

Early detection technology can provide crucial warning time during developing gas emergencies. The National Fire Protection Association (NFPA) reports that properly installed and maintained gas detectors can reduce fatality risk by up to 50% in gas-related incidents. For homeowners concerned about underground gas releases, we recommend a layered detection approach that monitors both indoor and outdoor environments.

Recommended Gas Detection Equipment

Natural gas detectors: Install UL-listed natural gas detectors in areas where gas lines enter your home and near gas appliances.
Carbon monoxide detectors: Place on each level of your home and near sleeping areas.
Combustible gas leak detectors: More sensitive units that can detect multiple types of combustible gases.
Smart detection systems: Internet-connected detectors that can send alerts to your phone when you’re away from home.
Outdoor methane sensors: For properties in high-risk areas or with known underground gas infrastructure nearby.

When selecting detection equipment, we typically recommend systems that offer both audible and visual alarms, battery backup capabilities, and interconnectivity between units. For optimal protection, consider systems that integrate with your existing home security or smart home platform.

Maintenance and Testing Schedule

Monthly testing: Test all gas and carbon monoxide detectors using the test button.
Battery replacement: Change batteries at least annually (or twice yearly with daylight saving time changes).
Sensor replacement: Most gas sensors degrade over time; replace units according to manufacturer recommendations (typically 5-7 years).
Professional inspection: Have a qualified technician inspect your gas lines and connections annually.
Calibration: For advanced detection systems, follow manufacturer guidelines for sensor calibration.

Immediate Response Actions During a Gas Geyser Emergency

The moments immediately following the detection of a potential underground gas release are critical. According to safety data from the American Gas Association, appropriate first actions can significantly reduce injury risk. Most gas-related incidents that result in serious injuries involve delayed evacuation or improper response actions. We advise all homeowners to memorize these steps and practice them regularly with household members.

If You Suspect an Underground Gas Release:

Evacuate immediately: Leave the area on foot without stopping to collect possessions.
Move upwind: Gas concentrations are typically lower upwind of the release point.
Maintain safe distance: Move at least 300 feet away from the suspected release area.
Call emergency services: Once at a safe distance, call 911 and your gas company’s emergency number.
Avoid creating ignition sources: Don’t use phones, flashlights, vehicles, or electrical switches near the leak area.
Warn others: Alert neighbors if possible, but don’t return to the danger zone.
Wait for professional assistance: Don’t attempt to investigate or repair a suspected gas leak yourself.

DO NOT Under Any Circumstances:

Turn electrical devices on or off: This includes light switches, appliances, and circuit breakers.
Use open flames: Never light matches, candles, or cigarettes.
Start vehicles: Car ignitions can provide an ignition source for gas.
Use landline phones: These can create small electrical sparks.
Attempt to locate the source: Leave this to trained professionals with proper equipment.
Re-enter the area: Even if the smell seems to dissipate, the danger may still be present.
