The maximum water capacity of cylinders that requires special protection against physical damage is?

The maximum water capacity of cylinders that requires special protection against physical damage is 1,000 pounds. This guideline is important because cylinders with a water capacity exceeding this threshold are typically larger and heavier, making them more difficult to handle. They are also at a higher risk of being involved in incidents that could lead to damage or potential accidents. As a result, regulations require that these larger cylinders be adequately protected to ensure safety during storage and transport. This can include protective barriers or cages, proper placement away from high traffic areas, and adherence to strict safety protocols to mitigate the risk of physical damage. This requirement is aimed at minimizing hazards associated with propane handling and storage.
