What information is marked on the collar of a cylinder?

The collar of a cylinder is specifically marked with important information related to its specifications and capabilities, particularly the tare weight and water capacity. The tare weight indicates how much the cylinder weighs when empty, which is essential for calculating the weight of the gas it contains. The water capacity is vital for understanding how much liquid propane the cylinder can hold, as this measurement ensures safe filling and handling.

This information is crucial for both safety and regulatory compliance, as filling cylinders beyond their rating can lead to dangerous situations. Knowing the tare weight allows users to accurately assess the amount of LP-gas added to the cylinder and ensures that it is filled appropriately according to safety standards. Therefore, understanding the markings on the collar helps in maintaining the safe use of LP-gas cylinders.
