Propane Gas Grill Danger: Hannah Storm’s Story

Earlier this year, ABC released the story and photos of ESPN anchor Hannah Storm, who was burned badly while using a propane gas grill in her own backyard. She suffered first- and second-degree burns attempting to light her grill in the same way that many of us do.  Her story serves as an excellent warning as to the dangers of propane tank explosions.

Hannah had lit her outdoor propane grill on a cold evening, and went back outside to check on the temperature of the grill.  She found that the wind had blown out the pilot light, and the grill was cool.  She turned off the propane gas, and then turned it back on.  Because the cover of the grill was opened, she assumed that it was ok to re-light the grill without any risk of fire.   Unbeknownst to her, the propane vapors were heavier than air, and had been gathering and pooling at the bottom of the grill (despite the grill not being on).  When she re-introduced a flame, an explosion occurred, setting her on fire.

Fortunately, Hannah escaped without catastrophic burn injuries.  She is very lucky.

Staggering Statistics of Propane Tank Explosions

76% of Americans own and enjoy propane gas grills, using them for cooking outdoors with family and friends. It only takes a split second, though, for this to turn into a disaster, as it did for Hannah.

The National Fire Protection Association (NFPA) has collected alarming statistics related to propane grilling accidents:

  • More than 6,100 accidental fires and explosions occur each year due to the improper use of grills, resulting s in 20,000 emergency room visits and $29.1 million of estimated damage
  • Approximately 20 deaths each year are caused by propane fires and explosions associated with gas grills.

Two Reasons Why Propane Grills Injure and Kill: Venting and Odor Fade


When propane tanks are exposed to excessive heat, the gas itself expands. If there’s not enough room for this inside the tank, a pressure release valve will open in order to allow propane gas to be let out of the tank. This process is venting…It occurs when the internal tank pressure exceeds 375 PSI and it prevents the tank from an explosion.

When the venting actually occurs, you will smell a pungent odor similar to “rotten eggs”. Propane is an odorless gas, and otherwise you would not realized when a gas leak might be happening. The awful smell is actually from the ethyl mercaptan, and additive mixed with propane to alert our sense to a leak.

Odor Fade

When gas is released from the tank during venting, and there is no odor, odor fade taking place.

When venting occurs, a pungent odor should be present. Propane is an odorless gas; the “rotten eggs” smell most people associate with propane is actually ethyl mercaptan, an additive which is mixed with propane gas to alert users of a leak. The problem arises when gas is released from the tank during venting, but there is no odor. This is known as “odor fade.”

If the propane leak is undetectable, it places you in grave danger.

There are also many instances of propane leaks causing explosions while propane tanks are being transported. Make sure the tank has plenty of ventilation while in your vehicle.

How Long Before the Mercaptan Odor Fades?

Experts claim that the odor of ethyl mercaptan disappears over time, anywhere between 5 to 7 days after a tank has been filled. It can become completely undetectable as soon as 3 weeks after the tank is filled.

Learn from Hannah that propane is heavier than air. Just because the grill lid has been opened doesn’t mean the propane has dissipated. Also, learn to recognize the smell and listen for a possible leak problem with the tank valves. Check propane tanks for tips on staying safe!
