On a bright, sunny day, the temperature of an improperly kept tank may easily rise to 120 degrees Fahrenheit. The higher the pressure within your tank, the hotter it becomes. Portable propane tanks include a relief valve that operates when internal pressure rises. This prevents the valve from being forced closed, which could cause it to leak or explode.
If you observe any of the following symptoms on a person you know, call 911 immediately: irritability, agitation, confusion, loss of consciousness, then you have probably found someone in need of emergency medical care related to a heated propane tank. Do not try to cool the tank with water; this could be extremely dangerous if you do not remove all of the heat quickly. Instead, call for help immediately.
While you should not store your tank inside, you should also avoid storing it in direct sunlight. If you allow it to get too hot, it could cause the valve on the back of the tank to open, releasing any excess gas into the atmosphere. Open valves are dangerous because they can't be closed once they have been opened. You must remove all valuables from around the tank before setting it in the sun.
If you choose to put your tank in full direct sunlight, make sure that you do so during the morning or evening when the temperature is at its lowest. You should also keep an eye on it throughout the day to make sure that it does not overheat. If it does, move it off the direct rays of the sun into the shade or indoors until it has cooled down.
Propane tanks can explode if they reach 200 degrees F internally. Therefore, it is important that you do not let them get overheated. Follow these tips to ensure that this does not happen.
Store your tank at least 15 feet away from buildings and vehicles. This ensures that there will be enough space for any heat that might be generated if the tank explodes.
They certainly can. Temperatures may quickly soar on a hot summer day. Although portable propane tanks have pressure relief valves to relieve pressure buildup, the best place to store a tank is out of direct sunlight... and its valve should be at least 15 feet from any structure or vehicle.
If you put a tank in direct sunlight, it will heat up and become pressurized. This can cause the tank to fail by either breaking down at the valve site or through overheating. Also, the tank's insulation may melt if left in direct sunlight for an extended period of time. If this happens, the gas inside the tank will be released into the atmosphere, which is not only unsafe, but also illegal.
It is important to keep tabs on your tank's level whenever you are away from your camp site. This will help prevent you from running out of fuel. It is recommended that you fill up your tank every other week at most; otherwise, you are putting yourself at risk of explosion.
An empty tank will blow up if exposed to air for several hours at a time. So when you are done using it, bury it at least 3 feet deep and 5 feet away from any structure or vehicle.
If you leave an unburied tank and go into camp next morning, it could still be there when you return.
