Your vessel is loading Class 1 explosives into hatch No. 2 when you observe an electrical storm approaching from the east. What actions should you take?

Correct Answer: Option C — halt loading operations and close hatch No. 2 until the weather is clear and the storm has passed

Handling Class 1 explosives presents extreme hazards during electrical storms. USCG regulations dictate that loading operations must halt immediately and hatches must be secured until lightning and storm activity have completely passed.
