Questions 1–8 — Shop Safety & Environmental Compliance
QUESTION 1.
While servicing an inboard gasoline engine, you detect a strong fuel odor before
starting the engine. What should be your FIRST action?
A. Start the engine briefly to locate the leak
B. Ventilate the engine compartment and inspect for fuel leaks before energizing
electrical systems
C. Disconnect the battery after starting the blower
D. Check ignition timing first
Correct Answer: B. Ventilate the engine compartment and inspect for fuel leaks
before energizing electrical systems.
Explanation: Gasoline vapors are heavier than air and may accumulate in the bilge,
creating an explosion hazard. Proper ventilation and leak inspection are the first
priorities before operating electrical equipment or starting the engine. Starting the
engine or energizing ignition systems before addressing fuel vapors significantly
increases ignition risk.
,QUESTION 2.
A technician is disposing of used engine oil after a routine service. Which practice
complies with environmental best practices?
A. Mix it with gasoline for disposal
B. Pour it into a storm drain
C. Store it in an approved container for recycling
D. Dilute it with water before disposal
Correct Answer: C. Store it in an approved container for recycling.
Explanation: Used oil must be collected in approved containers and sent to authorized
recycling facilities. Mixing oil with other contaminants, discharging it into drains, or
diluting it violates environmental regulations and can cause significant environmental
harm.
QUESTION 3.
Which fire extinguisher is generally appropriate for flammable liquid fires commonly
encountered in marine engine compartments?
A. Class A
B. Class B
C. Class D
D. Class K
Correct Answer: B. Class B.
Explanation: Class B extinguishers are intended for flammable liquid fires such as
gasoline and diesel fuel. Class A is for ordinary combustibles, Class D for combustible
metals, and Class K for cooking oils.
, QUESTION 4.
A technician notices damaged insulation on a battery cable. What is the BEST
corrective action?
A. Wrap the damaged area with masking tape
B. Ignore the damage if the conductor is intact
C. Replace the damaged cable
D. Paint over the exposed insulation
Correct Answer: C. Replace the damaged cable.
Explanation: Damaged battery cables can create short circuits, voltage drops, and fire
hazards. Replacement is the proper corrective action. Temporary repairs such as tape
are not considered reliable for primary battery cables.
QUESTION 5.
Which personal protective equipment is MOST important when disconnecting marine
batteries?
A. Hearing protection
B. Safety glasses
C. Steel-toe boots only
D. Respirator
Correct Answer: B. Safety glasses.
Explanation: Batteries contain corrosive electrolyte that can splash unexpectedly during
servicing. Eye protection is essential. Additional PPE may also be appropriate
depending on the maintenance task.
