Relief Valve Actuating
On hot days when the sun is high overhead and a propane delivery has recently been made, the safety relief valve may open slightly allowing excess pressure to vent. If the relief valve is opened, the protective cap will be removed from the top of the valve from the pressure buildup, as pictured to the left. DO NOT LOOK INTO THE RELIEF VALVE OR TAP IT WITH ANYTHING. Doing so may cause the relief valve to open all the way. The relief valve is doing what it was designed to do and on hot, sunny days, propane tanks are subject to excess pressure due to expanding liquid within the tank. One way to remedy the situation is to cool the tank down by spraying water from a garden hose on the surface of the tank. This will generally cause the relief valve to close.
I believe the article primarily is about large home propane tanks.
And I will add that these propane cylinders should not be stored indoors. My new cylinder sits out on the patio until I empty and dispose of my expired one.
