By law, when a propane tank reaches 12 years of age, it can no longer be filled. We see this frequently at our propane platform here in Peabody, and with the Fourth of July weekend coming up, we figured weâd share with you how to tell whether your grill tank is out of date.he only thing youâll need is the manufacturing date. As of the day of this post, any tank with a manufacture date before 07-01 we would not be able to fill. If a tank is more then 12 years old, it cannot be filled.
The noun CUMULONIMBUS CLOUD has 1 sense: 1. a dark cloud of great vertical extent charged with electricity; associated with thunderstorms. Familiarity information: CUMULONIMBUS CLOUD used as a noun is very rare.
Cumulus clouds are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called fair-weather clouds. The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
