CTR 156CT Propane Practice Test

Handling and filling LPG cylinders is a hazardous operation that must be performed only by trained personnel at an approved refueling facility. A customer cannot take a 20 lb Autogas cylinder to their car and fill it there because the process requires calibrated equipment to control the exact amount of gas put into the cylinder and to prevent overfilling. LPG expands with temperature, so overfilling can lead to leaks, venting, or pressure-related accidents. Fueling stations are equipped with proper nozzles, safety valves, ventilation, and procedures to manage these risks. The standard practice is to direct customers to a licensed Autogas refueling site for a safe, compliant fill, not to fill cylinders at home or in a car.
