Frequently asked questions about propane bottles and tanks?

What exactly is propane?

Propane is a flammable gas that is sometimes generically referred to as LP-Gas, LPG, or Liquefied Petroleum Gas. LP-GAS is typically a propane-butane mixture. Propane might also contain small amounts of other flammable gases, such as, ethane, ethylene, propylene, isobutane, or butylenes.

How is LP-GAS produced?

Seventy percent of propane and butane is processed from natural gas. The remaining thirty percent is extracted from crude oil. There are four major blends of LP-Gas: commercial propane, HD5 propane, commercial butane and butane propane blends.

Why does LP-Gas smell so bad?

A distinct commercial odorant is added because the gas is odorless in its natural state.

Why won't my propane dealer refill my tank?

They have probably determined that the tank is not safe to fill or it is overdue for a certification inspection.

What does a certification inspection look for?

Tanks are inspected for excessive rusting, denting, gouging or pitting, missing neck ring or bottom ring, and presence of an overfill protection device. (See picture)


What do I do with the old tank?

As of January 1, 2002, all permitted LP-GAS dealers, wholesalers, and retailers are required to accept old tanks (4 to 40 lb) for refurbishment, recycling or disposal at no charge to the consumer.

Can I throw the old tank in the garbage?

NO! The old tank is still dangerous and must be properly handled.

What are your suggestions for handling LP-GAS tanks?

  • Remember that LP-GAS is a flammable gas stored under pressure.

  • Know that leaking LP-GAS can cause a fire or explosion if the gas reaches an ignition source.

  • Be aware that rapidly heated cylinders can also explode in a fire situation.

  • Never take an LP-GAS tank inside any building or dwelling, even momentarily.

  • Never store or use LP-GAS tanks in any building, garage, or enclosed space.

  • Realize that LP-GAS vapors are heavier than air. The vapors will flow into low areas such as cellars, sumps, and window-wells.

  • If there is a gas leak or uncontrolled fire, evacuate the area. Call the fire department from a telephone away from the leak, such as from a neighbor's house or from a cell phone or pull the nearest street fire alarm box.

  • Always keep tanks standing upright.

What are your suggestions for LP-GAS grills and burners?

  • Place grill on a noncombustible surface only at grade level.

  • Make sure that the grill is at least 10 feet from any combustible surfaces such as buildings, walls, deck railings, and vehicles.

  • Make sure that the grill is at least ten feet from any possible ignition sources such as air conditioners, lights, or cars.

  • Do not allow anyone to smoke when working with a LP-GAS tank.

  • Keep children and pets away from the grill.

  • Keep the LP-GAS tank shut off when not in use.

  • Store the LP-GAS tank in a shaded area. Heat from sunlight will cause the gas to expand and vent from the tank.

  • Periodically check all connections to make sure that they are secure and that there are no leaks.

  • When transporting a LP-GAS tank for refilling, do not leave it inside an enclosed car or trunk because the gas will vent automatically when it is heated or warmed.

  • Keep all hoses and connections free from spilled food, grease, and dirt.
