How Common Are Propane Explosions?

A propane explosion in Maine that killed a firefighter and injured 8 others has put propane back in the spotlight. Both propane explosions and propane deaths are rare, but the burns and destruction caused by exploding propane tend to be more serious than explosions triggered by other causes.

Propane Explosion Facts

There are an estimated 60 million propane-fueled devices in the United States, according to the National Fire Protection Association. These range from propane-fueled grills to propane heating systems similar to the one that exploded in Maine, leveling a building.

Propane tends to vaporize quickly in air, but it is also heavier than air and will sink to the lowest level possible. The explosion in Farmington, Maine occurred because a large volume of propane had settled into the basement of the building. When the propane ignited, it lifted the building into the air and shattered it.

Overall, propane is one of the safest fuels available. Data for the Occupational Safety and Health Administration found just one propane-related death in 2018 among 13 incidents. That did represent a sharp decline from 2017, when there were 5 propane explosion deaths from 22 incidents, one of which involved an employee who was hit and killed by a propane delivery truck. One of the injuries occurred while a worker was moving propane tanks and did not involve fire or explosion.

The majority of propane-related deaths are the result of severe burns from a propane fire. Tank-refueling operations and repairs to propane equipment tend to be the most common causes of propane-related injuries, though exposure to propane or carbon monoxide released when propane burns can also be a source of injuries.

How to Prevent Propane Explosions

1. Never let a propane system run empty. Air and moisture can enter the system, creating leaks and explosive hazards. Turn off valves that connect propane before propane runs out.
2. Never modify propane equipment yourself. Only a trained technician should install or replace propane valves, piping and connectors.
3. Never refill propane tanks yourself. Propane should only be refilled by trained professionals.
4. Only allow professionals to light pilot lights. If pilot lights go out, it could be a sign of equipment failure.
5. Always store propane tanks outdoors. Remember that propane pools below the site of a leak. Outdoor storage prevents explosive gas build-up. Never store tanks in a basement.
6. Check vents and valves in inclement weather. Be sure heating systems are properly vented in wintertime. Carbon monoxide can kill.
7. Turn off propane valves when equipment will not be used. Always disconnect propane tanks from grills and portable equipment before storing and store the tanks outside. Turn off propane from larger tanks at the source, as well as for individual appliances before closing a seasonal residence.

What Should You Do If You Smell Propane?

Propane, like natural gas, has odor added to help people detect leaks. This odor smells like rotten eggs.

If you smell propane:

1. Leave the area immediately. Get as far as possible from the leak before doing anything else.
2. Turn off the propane if this can be done safely. Do not enter an area with propane to turn off a valve; a spark from static electricity could cause ignition. If there is a valve located well away from the leak, turn off the gas.
3. Call for help. Never use a cell phone near a propane leak. Go to a neighbor’s home or as far as possible from the leak before calling for help.
4. Stay away from the area until the leak has been resolved.
5. Prevent non-professionals from entering the area. Propane technicians and first responders are the only people who should be allowed near a propane leak.
6. Have all equipment inspected and repaired. Before turning propane back on, have a technician examine all equipment in the area of the leak and fix any faulty equipment.
