Title 46 - Shipping
(a) When sulfur is loaded in a deep hold with general cargo in the 'tween deck hold above the sulfur, a dust proof wooden bulkhead enclosure must be built in the hatchways from the over deck of the lower hold to the weather deck forming a tight enclosure capable of preventing sulfur dust from entering the 'tween decks during loading.

(c) Cowl ventilators serving the hold into which sulfur is being loaded or discharged must be opened to provide circulation of air. (d) No smoking is permitted on board the vessel and “No Smoking” signs must be conspicously posted. (e) If a metal chute is used it must be grounded using a flexible cable. (f) Upon completion of loading, the sulfur must be leveled off. Any decks, bulkheads, or overheads containing sulfur dust must be swept clean or washed down.
