Section 1: Safety & Professional Practices
Q1: Before performing any maintenance on an RV's electrical system, what is the correct
"Lockout/Tagout" procedure?
A. Turn off the main breaker inside the RV.
B. Unplug the shore power cord and tape the breaker in the off position at the pedestal.
C. Disconnect shore power and the negative battery cable, then tag the disconnects to prevent
accidental reconnection. [CORRECT]
D. Flip the battery disconnect switch inside the RV.
Correct Answer: C
Rationale: A comprehensive lockout/tagout requires isolating all energy sources. Simply unplugging
shore power leaves the battery as a live source, and simply flipping a disconnect switch doesn't
physically prevent someone from plugging the cord back in. Tagging warns others not to restore power
while work is in progress.
Tip: Always treat every wire as if it is live until verified with a meter.
Q2: An RV technician smells propane upon entering a unit for service. What is the immediate action?
A. Turn on the exhaust fans to clear the gas.
B. Light a match to find the source of the leak.
C. Evacuate the area, extinguish ignition sources, and shut off the main propane tank valve. [CORRECT]
D. Call the supervisor from inside the RV.
,Correct Answer: C
Rationale: Propane is heavier than air and settles in low areas, creating an explosion risk. The first
priority is safety: evacuate people, eliminate ignition sources (don't flip light switches), and stop the leak
at the source (the tank). Ventilating fans (Option A) might spark; Option B is obviously dangerous.
Tip: Know the location of the main LP tank valve before starting work.
Q3: When lifting an RV using hydraulic jacks or jack stands, where should the lifting force be applied?
A. The frame rails or designated lift points specified by the manufacturer. [CORRECT]
B. The axle tubes or differential housing.
C. The slideout rails.
D. The bumper or receiver hitch.
Correct Answer: C
Rationale: RV frames are designed to support the weight. Lifting on axles can damage suspension
components, seals, or alignment. Lifting on bumpers or slide rails can cause structural bending or failure.
Always consult the manufacturer's manual for specific lift points.
Tip: Use wheel chocks in addition to jack stands to prevent rolling.
Q4: What is the proper classification for a Class ABC fire extinguisher?
A. It is suitable for electrical fires only.
B. It is suitable for combustible metals.
C. It is suitable for ordinary combustibles, flammable liquids, and electrical fires. [CORRECT]
D. It is suitable for cooking oils and grease.
Correct Answer: C
Rationale: Class A covers wood/paper (ordinary combustibles), Class B covers flammable liquids (grease,
gas, oil), and Class C covers electrical equipment. A Class K extinguisher is required for deep fryer oil
fires. An ABC extinguisher is the standard multipurpose tool for RVs.
Tip: Check the pressure gauge monthly to ensure the needle is in the green zone.
,Q5: Which Personal Protective Equipment (PPE) is mandatory when grinding metal or working under an
RV?
A. Ear plugs and steel-toed boots.
B. Safety glasses and gloves. [CORRECT]
C. Hard hat and high-visibility vest.
D. Respirator and face shield.
Correct Answer: B
Rationale: Safety glasses protect eyes from flying debris (grinding) or falling dirt (undercarriage). Gloves
protect hands from sharp edges, heat, and chemicals. While boots are recommended, eye protection is
the absolute minimum critical PPE for these specific tasks to prevent immediate injury.
Tip: Keep a pair of safety glasses in your tool bag so they are always accessible.
Q6: When working with lead-acid batteries, which hazard must be addressed?
A. The batteries release nitrogen gas.
B. The batteries contain sulfuric acid which can cause severe burns. [CORRECT]
C. The batteries are a shock hazard due to high voltage (12V).
D. The batteries emit carbon monoxide during charging.
Correct Answer: B
Rationale: Lead-acid batteries contain sulfuric acid electrolyte, which is highly corrosive. They also emit
hydrogen gas during charging, which is explosive, not nitrogen or carbon monoxide. While 12V can
shock under wet conditions, the acid burn is the primary chemical hazard.
Tip: Have a mixture of baking soda and water nearby to neutralize acid spills.
Q7: What does a Carbon Monoxide (CO) detector detect?
A. Propane gas leaks.
B. Smoke particles.
C. Incomplete combustion gases that are odorless and colorless. [CORRECT]
, D. Rising heat levels.
Correct Answer: C
Rationale: Carbon Monoxide (CO) is a byproduct of incomplete combustion (engines, furnaces,
generators) and is odorless, colorless, and deadly. Propane detectors detect LP gas (mercaptan added
for smell). Smoke detectors detect particulates.
Tip: CO detectors have a limited lifespan (usually 5-7 years) and must be replaced periodically.
Q8: When connecting to shore power, what should be verified FIRST?
A. That the pedestal breaker is on.
B. The voltage and wiring polarity at the pedestal using a voltmeter or surge protector. [CORRECT]
C. That the RV main breaker is off.
D. That the extension cord is rated for 30 amps.
Correct Answer: B
Rationale: Connecting to a pedestal with "hot skin" (reverse polarity), open ground, or incorrect voltage
(low/high) can instantly damage the RV's electrical system. Testing before plugging in prevents damage.
The RV main breaker should be off during connection, but verifying the source power quality is the first
step.
Tip: Use a digital voltmeter or a dedicated 30/50A circuit analyzer before plugging in.
Q9: Which tool is specifically required when working on high-voltage hybrid drivetrain components (if
applicable)?
A. Insulated screwdrivers and Class 0 high-voltage gloves. [CORRECT]
B. Standard mechanics gloves.
C. A non-contact voltage tester only.
D. A standard multimeter.
Correct Answer: A
Rationale: Hybrid systems can carry 300V or more. Standard gloves do not provide insulation against
high voltage. Class 0 high-voltage gloves and insulated tools are required to prevent lethal electrocution.
