Which condition must be checked on a cylinder before filling?

The presence of excessive corrosion on a cylinder is a critical factor to check before filling it with propane or any other liquefied gas. Corrosion can compromise the structural integrity of the cylinder, leading to leaks or even failures during operation. A highly corroded cylinder may not safely hold the pressurized gas, increasing the risk of accidents and hazards during filling and usage.

Closing this safety gap is essential as it not only protects individuals handling the cylinder but also prevents potential environmental harm. Ensuring that a cylinder is free from excessive corrosion is part of standard safety protocols in the handling and use of LP gas cylinders, making it a fundamental aspect of safety checks prior to filling.
