Recreational Vehicle (RV) Technician Practice Test

What must you check before filling a propane cylinder?

1. Leakage test

2. Weight of the cylinder

3. Date of manufacture

4. Pressure gauge

The correct answer is: Date of manufacture

Before filling a propane cylinder, it is essential to check the date of manufacture. This is crucial because propane cylinders have regulations regarding their lifespan and serviceability. Most propane cylinders must be recertified or replaced after a certain number of years from the date of manufacture. Ensuring that the cylinder is still within its service life not only guarantees safety but also compliance with regulations governing the use of propane equipment. While other factors such as leakage tests, weight, and pressure gauges are important for the overall safety and functionality of propane cylinders, confirming the date of manufacture specifically addresses compliance and the safe operational limits of the cylinder itself.
