RVTI Level 1 Certification Questions and answers |
Updated RATED A+ | 2026
Propane, as extracted,
Is odorless and colorless
The device used on a propane tank to reduce pressure is called a
Regulator
The boiling point for propane is
-44F (-42C)
A property of propane is that, when heated, it
Expands
When an element or compound changes from the liquid phase to a vapor, it is called
Vaporization
When working with propane systems, the most important factor to consider is
Safety
Propane is flammable, can explode with pressure, and is able to
Freeze skin
It is important to wear gloves when using propane because it can
Freeze the skin
When working with propane, it is important to wear
Appropriate gloves
To close a service valve on a propane tank, it is best to tighten the valve with
A hand
In a shop environment, always wear
Safety glasses
When transporting or storing containers, always use
,A POL plug or dust cap
Which service valve is mandatory in the RV industry?
Type I OPD
What is now required to be part of ASME tanks but was not required prior to 1983?
OPD
The maximum allowable working pressure on an ASME tank can be found on the
Data plate
The most common securing methods for cylinders include
Adjustable straps and T-bars
Purging is necessary for
New and contaminated containers
For purging, you must increase pressure by 15 psi and is the total number of purgings
required.
5
The tare weight of a cylinder is 19 pounds. The propane capacity is 20 pounds. To how many
pounds should the cylinder be filled and to what level?
39 pounds; 80% level
The relief valve will function if the pressure of the compressed air plus the pressure of the
propane meets or exceeds the relief valve setting of
375 psi
What can occur if a horizontal cylinder is not stored in its proper position?
Liquid propane can enter the vapor system
Which of the following is NOT an appurtenance?
Mounting bracket
Black or green connector knobs on Type 1 OPD service valves indicate
Flow rating
ASME tanks are usually bolted to
, The frame
On double cylinder assemblies, make sure
The cylinder tray is attached to the unit's frame
When purging, avoid applying a vacuum to containers that may have contained
Propane
Failure to purge when necessary can cause
Odor fade and false pressure
Cylinders should be filled using
The weight or volumetric method
When releasing an air/gas mixture of propane, ensure a minimum of feet in every
direction between the container and source of ignition.
25
The lockup pressure test verifies the pressure at which
The regulator locks up when no propane is flowing
Immediately after conducting the operating pressure test
Close up the gas cock
Any regulator pressure over inches WC will require the regulator to be replaced.
14
During a timed pressure drop test, no pressure drop should be detected. If there is a pressure
increase due to thermal expansion , and if there is a pressure drop .
Repeat the test...locate and repair leal, and retest
What should be documented for a timed pressure drop test with a test apparatus?
Inches of water
When adjusting a system regulator, the operating test should show a working pressure of about
11 inches, and the lockup pressure should never exceed inches.
