Propane Tank Leaks, Basement Gas Pooling, and Cylinder Overheating¶

Millions of rural homes, farms, cabins, outdoor kitchens, and recreational vehicles rely on Liquefied Petroleum Gas (LPG / propane) stored inside outdoor bulk stationary tanks (ranging from 450 to 4,000 liters / 120 to 1,000 US gallons) or portable 9-kilogram (20-pound) steel cylinders. While propane and natural gas are both odorized with foul-smelling ethyl mercaptan (which smells like rotten eggs, skunk spray, or decaying cabbage), propane behaves in a fundamentally different and far more treacherous physical manner when it leaks inside a building. Natural gas (methane) is lighter than air (specific gravity 0.60), so it rises toward the ceiling and vents out upper windows. Propane gas is 1.52 times heavier than air. When propane leaks from a basement furnace valve, a water heater line, or a corroded copper pigtail pipe, the invisible gas sinks straight to the floor like invisible water, flowing silently down basement stairs, pooling knee-deep inside cellars, crawlspaces, and sump pits, and waiting for a water heater pilot light, sump pump float switch, or refrigerator compressor relay to ignite a devastating foundation-level explosion.

Two additional propane-specific emergencies catch homeowners off guard every year: odorant fade, where leaking underground propane gas filters through soil or rust inside a new steel tank, stripping out the rotten-egg smell so a basement fills with 100 percent odorless explosive gas; and Boiling Liquid Expanding Vapor Explosions (BLEVE), when a brush fire, garage fire, or barbecue grease fire heats the upper steel shell of a pressurized propane tank until the metal softens and ruptures into a massive rocket-propelled fireball. Knowing how to evacuate a basement without touching a single light switch or cell phone, how to shut the handwheel valve under the outdoor tank dome, and when to evacuate 800 meters (½ mile) away from a roaring tank pressure relief valve saves your family's lives.

Sala boye sikoyo¶

If you smell rotten eggs or skunk odor in your home or yard, hear a loud hissing sound from a propane tank or appliance, or see fire impinging on a propane cylinder, execute these six actions immediately:

1. Evacuate everyone from the house immediately, ESPECIALLY from basements and ground floors: Because propane is 1.5 times heavier than air, a leaking basement can be above the Lower Explosive Limit at ankle and waist level before anyone upstairs smells a faint whiff. Order everyone upstairs and out the front door on foot immediately; never go down into a basement to check a furnace or sniff near the floor.
2. Do NOT flip any light switches, unplug appliances, use a landline or cell phone indoors, or press an electric garage door opener: When a room contains a propane-air mixture between 2.1 percent and 9.5 percent, the microscopic electrical arc inside a wall toggle switch, a thermostat relay, a keyless entry fob, or a garage door opener motor will detonate the entire house. Leave the lights exactly as they are and walk out through an unlocked manual door.
3. Never start or move a car, lawnmower, or golf cart parked in the garage or driveway near the leak: Internal combustion starters and hot catalytic converters ignite ground-hugging propane vapor plumes instantly. Leave all vehicles parked where they are and walk at least 100 meters (330 feet) upwind and uphill from the house.
4. If the leak is unignited and you can safely reach your outdoor bulk propane tank upwind, close the main supply valve clockwise: Lift the hinged metal protective dome on top of your outdoor residential propane tank, locate the round brass or metal Service Shutoff Handwheel Valve, and turn it clockwise (to the right, "righty-tighty") until firmly closed. Never attempt to close a valve if the tank is hissing liquid frost onto your hands, if the tank is inside a low pit, or if fire is anywhere near the cylinder.
5. NEVER extinguish a flaming jet of propane shooting out of a tank valve unless you can immediately turn off the fuel flow: If a leaking propane cylinder catches fire at the valve or pressure relief port, the flame is safely burning off the escaping gas outside. If you extinguish the flame with a dry chemical extinguisher while propane continues pouring out, the unburned heavier-than-air gas will pool across the ground and explode violently the instant it finds a new spark.
6. If fire is heating a propane tank or the safety relief valve begins roaring like a jet engine, evacuate 300 to 800 meters (1,000 feet to ½ mile) away behind solid cover: A propane tank exposed to fire is at imminent risk of a BLEVE (Boiling Liquid Expanding Vapor Explosion). Call your local banimero ya mbalakaka (911 in the United States and Canada, 112 across the European Union, 999 in the United Kingdom) and your propane gas supplier from a safe distance uphill.

Comparison matrix: propane (LPG) vs. natural gas (methane) in home emergencies¶

Homeowners who move from a city house served by municipal natural gas to a suburban or rural property served by propane often apply natural-gas instincts that are fatal during a propane leak. Compare their physical and explosive behaviors:

Anatomie ya 4 étapes ya réservoir ya propane BLEVE¶

   [HOW A PROPANE TANK BLEVE DEVELOPS]

   1. External Fire Heats Tank   --->  Liquid propane boils violently; internal
                                       pressure hits 2,585 kPa (375 psi).

   2. Relief Valve Pops Open     --->  A 3-to-10-meter (10-to-33-foot) blowtorch of
                                       fire roars out the top relief valve, dropping
                                       the liquid level inside the tank.

   3. "Mur ya kokauka" Steel Weakens   --->  Below the liquid line, boiling propane keeps
      Above the Liquid Line            the steel cool. ABOVE the liquid line (the
                                       vapor space), flames heat the dry steel above
                                       600°C (1,100°F) until it loses 70% of its
                                       tensile strength and bulges like a blister.

   4. Catastrophic Split &       --->  The weakened upper steel rips open; superheated
      270:1 Flash-Boil Fireball        liquid propane flashes instantly into a 100-meter
                                       (330-foot) fireball and launches steel shrapnel
                                       up to 500 meters (1,600 feet) away.

Bilembo ya likebisi oyo ekoki kozala na ntembe te ya BLEVE oyo ezali koya (Bima mbala moko)¶

Soki moto ya structure, moto ya motuka, to moto ya matiti ya zamba ekomi na réservoir ya propane ya libanda to cylindre portable, tala pe yoka bilembo minei oyo ya likebisi ya BLEVE oyo ezali pene:

1. Soupape ya kosilisa pression esalaka na koganga ya moteur jet oyo ezali kokanga matoyi: Tango soupape ya soulagement ya sécurité ya réservoir efungwami na se ya impingement ya moto, ebetaka fulu vertical ya flamme ya pembe-orange oyo ezali koganga na 5 à 15 mètres (16 à 50 pieds) na mopepe. Ntango valve ya lisungi ezali kosala mosala na yango, ekoki te kopekisa BLEVE soki milinga ezali kokoba kopesa molunge na coquille ya likolo ya bibende oyo ekauki ya réservoir.
2. Pitch ya soupape ya relief oyo ezali koganga ezali komata (Rising Whistle): Lokola mayi ezali kotɔka mpe réservoir ezali kopela makasi, makelele ya koganga ya gaz oyo ezali kokima ezali komata se na ton lokola bouilloire ya ti ya monene.
3. Peinture oyo ezali kopumbwa, kokatakata, to ebende ya motane/orange oyo ezali kongɛnga na ndambo ya likoló ya réservoir: Yango elakisi ete bibende oyo ekauki oyo ezali na esika ya vapeur likoló ya nivo ya mai ezali koleka 550 degrés Celsius (1 020 degrés Fahrenheit) mpe ezali na ntaka ya basegɔnde mpo na kopasuka ya structure.
4. Ntango kobanda na contact direct ya flamme tii na BLEVE ekoki kozala mokuse lokola 8 à 15 minutes: Ba tests ya NFPA na Département ya Transport ya Etats-Unis (DOT) Emergency Response Guidebook (ERG Guide 115) elakisaka que réservoir ya propane oyo esili ko refroidir te oyo ezipami na flamme directe ekoki kopasuka na na se ya 10 minutes.

Evacuation distances for fire-involved propane tanks (DOT ERG Guide 115)¶

• For a small 9-to-45-kilogram (20-to-100-pound) portable grill or RV cylinder in a fire: Evacuate everyone at least 100 to 300 meters (330 to 1,000 feet) away and move behind the solid masonry wall of another building (never stand in direct line-of-sight watching a burning garage or barbecue grill, as rupturing 20-pound cylinders rocket sideways through fences and car windshields).
• Mpo na réservoir ya monene ya 450 kino 4.000 litres (120-to-1.000-gallon) ya ndako na moto: Kolongola mbala moko 800 mètres (½ mile) na ngambo nyonso, mpe kotelema ata moke te na molongo na nsuka mibale ya rond (mitó) ya cylindre horizontal, oyo emata na fusée libanda na nzela ya axe molai ya tank na ntango ya kopasuka.
