Alabama Propane Dispensing Safety Test 2026 – Complete Practice Exam

Filling a cylinder by weight is controlled by the total weight of the cylinder plus its contents. The maximum permitted fill is the cylinder’s stamped maximum gross weight, so you place the cylinder on a scale and add propane until the scale shows that total weight. The tare weight (empty cylinder) helps you know how much propane has been added, but the stopping point is the total weight reaching the specified limit. A gauge, meter, or dial typically measures pressure or flow, not the amount of propane inside, so they can’t reliably indicate when the safe weight limit is reached. Using the scale directly provides the accurate, safety-focused check needed for this method.
