HV Exit Exam • Set 4 Question 10 of 30

The supply voltage for hand-held portable power tools and inspection lamps in marine accommodation and engine spaces should not exceed 1000 volts.

✓

Direct Answer

Option B: False

Under SOLAS and marine regulations, hand-held portable tools must not exceed 250 V (often 110 V via isolating transformers), and inspection lamps in confined/wet spaces are restricted to safety extra-low voltage (SELV, ≤ 50 V or 24 V).

All Options

True

False (Correct Answer)

Detailed Explanation & Context

Relevant Framework: STCW 2010 Manila Amendments • DG Shipping E-Learning & Exit Exam Standards • High Voltage Safety Officer & Switchgear Operations (HV).
