VIDEO - Transporting Propane Safely
How many of us just throw that empty propane cylinder into the trunk and head off to have it filled? I've seen the results of a couple of explosions involving propane in vehicles and it wasn't pretty. The following video is from Technical Safety BC (formerly the BC Safety Authority) and shows you how to safely (and legally) transport a 20 pound propane cylinder in your car or RV.
How about gasoline?
An interesting video about volitile gasses but that's nothing compared to gasoline.
I happen to live in South Surrey, 8 km. to Blaine. It's worth it for me to nip over the border for gas, which goes in my vehicle gas tank.
What is really scary, are the number of vehicles loaded with jerry cans full of gasoline heading back to the border. I say jerry cans but I've seen all types of containers. Recently, there was a very expensive BMW SUV next to me. The fellow filled SIX plastic water jugs (The type that fit upended in a cooler.) and put them loose in the back of his vehicle. The necks were capped off with what looked like Saran Wrap, held in place with elastic bands.
If even one of them spilled and the fumes found an ignition source, his Bimmer would have gone up like a Roman Candle.
IF he survived, which I doubt, you and I would have bought him a new one, thanks to ICBC. Stupidity should be uninsurable!
I followed up on the question with CVSE who are generally the best source of transportation of dangerous goods information in my experience. The response was that you may carry up to 150 liters of gasoline in approved containers whose capacity is no more than 30 liters.
Pressure relief valve
This video should have explained the reason for keeping a propane cylinder or tank upright.
Propane cylinders/tanks have a pressure relief valve located at the top side to allow for the release of gas (if the pressure exceeds a set limit) to prevent the cylinder/tank from exploding.
Propane cylinders/tanks need to be kept away from heat sources, including direct exposure to the sun, to prevent excessive gas pressure within the cylinder/tank.
The pressure relief valve may not function if a propane cylinder/tank is on its side or upright, and liquid propane covers the pressure relief valve. This could lead to an explosion.
Propane cylinders/tanks need to be kept/stored upright even if they are suspected of containing no propane liquid or gas.
Propane cylinders need to be secured or stored in a way that prevents them from falling over, which may damage their valves.
