Propane Explosions: Preparing for Extreme Weather

. By Heidi Turner

A propane explosion at a care center in Pennsylvania late in November resulted in five employees being sent to hospital to be treated for their injuries.

The explosion occurred when a 12-ounce can of propane that was being used to heat a small oven device blew up in the face of one of the employees of the care center. The victims who were sent to the hospital suffered from either burns or smoke inhalation. Investigators do not yet know what caused the can of propane to explode.

A couple from Ohio is in the hospital suffering from severe burns after their home was destroyed in a series of explosions. Both victims suffered second- and third- degree burns over up to 35 percent of their bodies. The fire was started after a scented candle was lit which ignited the propane. Earlier in the day the couple had been replacing a filter in a pipe connected to their home's water heater which was heated by propane gas. They also used a torch powered by propane to solder the waterlines. In the evening the couple smelled gas in the home but believed the odor was leftover from the propane torch so a candle was lit to rid the home of the smell. In fact, the propane smell was caused by a leak from one of the gas lines to the water heater.

These are just two reminders of how important it is to be safe when working or living with propane. In addition to the other important safety tips, outlined in previous articles on this website, there are more things that you should know about propane, especially when dealing with extreme weather.

If you know that the weather is going to turn bad, for example heavy rain or snow, there are some steps you can take to protect your propane system from leaks and potential explosions.

Heavy rain: If you know ahead of time that flooding is expected in your area turn off the gas valve at the cylinder or tank before the water begins to rise and do not turn the gas back on until the system and appliances have been checked by a qualified technician. Exposure to water may mean that regulators, pressure relief valves, and/or automatic controls have to be changed, or that main and pilot burners need to be cleaned. Do not attempt to perform these tasks yourself as you can cause more damage to your propane system. Wait for a qualified technician who will make any repairs necessary.

Snow: Keep regulators, regulator vents, piping, tubing, and valves clear of heavy snow as damage caused by heavy snow can lead to a gas leak and potential explosion. All vents, chimneys, and flues must also be snow-free so all appliances can vent properly. This is always important, but especially so for people who live in mobile homes. When clearing snow, use a broom instead of a shovel as a broom is less likely to cause damage to your propane system. Keep in mind that service technicians may need access to your propane tank, so make sure there is a clear path to the tank.

If you notice anything unusual about your propane system after severe weather, for example the tank has shifted position or gas lines look out of place, turn off the main gas supply valve on your propane tank if it is safe to do so and contact a qualified service technician. If you smell any gas or suspect that gas has leaked always leave the area immediately and contact the authorities from a safe distance from the propane leak.

Although propane is heavier than air and therefore tends to pool in low-lying areas, it is possible that propane vapor will follow air currents in buildings to higher levels. If you are upstairs and smell propane, do not just assume that it's your imagination. It is possible for propane to move into higher areas. Leave the house immediately and call the authorities.
