When filling a cylinder, which of the following is not a safety requirement?

When filling a cylinder with LP-gas, it is crucial to follow specific safety requirements to ensure the safety of both the personnel involved and the environment. Personal protective equipment (PPE), proper training, and correct filling procedures are all fundamental components of a safe LP-gas dispensing process.

PPE is necessary to protect individuals from potential hazards such as exposure to gas or potential burns. Proper training ensures that employees understand how to handle LP-gas safely, including recognizing hazards and knowing emergency procedures. Correct filling procedures are vital to preventing overfilling and ensuring that cylinders are filled safely and within legal guidelines.

Storing cylinders indoors is not a safety requirement when filling; in fact, it is typically recommended to do so outdoors in a well-ventilated area to avoid accumulation of gas and potential leaks. Thus, the option regarding being stored indoors does not align with established safety practices, making it the correct choice for what is not a safety requirement when filling a cylinder.
