What is the maximum weight of portable refillable LP-gas cylinders that must have a warning label applied if not filled on site?

The correct answer regarding the maximum weight of portable refillable LP-gas cylinders that must have a warning label applied, if not filled on site, is 100 lbs. This requirement is important for ensuring the safety of users and those handling the cylinders. The warning label serves to inform users about the specific handling and safety protocols necessary for safe operation.

Cylinders that exceed this threshold are generally considered more hazardous due to the larger quantity of flammable gas they carry. When these are transported away from the filling location, there’s a greater risk if safety measures are not strictly followed. Warning labels play a crucial role in providing crucial information about the potential hazards of handling large cylinders and ensuring users are aware of the safety procedures necessary for their operation.

While cylinders lighter than this weight may still require guidelines for safe handling, the specific regulatory requirements focus on those weighing 100 lbs or more, emphasizing the increased responsibility and precautions needed for larger volumes of propane.
