Table K-Classification: Descriptive name of article Characteristic properties, cautions, markings required Label required Sulfur.. Flowers of sulfur. Sulfur flower. Brimstone. Sulphur. A mineral substance in the form of hard No label relumps or amorphous powder. Insoluble in water. Crude sulfur in bulk is dangerously inflammable and readily fusible by heat. Will ignite by friction. When burning gives off sulfur dioxide, a suffocating gas. Sulfur dust given off in loading crude sulfur in proper proportions with air forms an explosive mixture and may be ignited by static electricity, open flame or spark. Do not stow sulfur with carbon, charcoal, lampblack, fats, oils, chlorates, phosphates, phosphorus, or other carriers of oxygen. In the presence of carbon, charcoal, lampblack, and other carbonaceous substances, fats and oils may produce spontaneous heating and ignition; while with chlorates, phosphates, phosphorus and other oxygen carriers it may produce explosive mixtures. Outside barrels, boxes or bags shall be marked with the shipping name of the product as shown herein or "Hazardous Article." quired. NOTE: In the loading, handling and unloading of sulfur in bulk the following conditions shall be complied with: (a) When sulfur in bulk is loaded in a deep hold with general cargo in the tween deck hold above the sulfur & dust proof wooden bulkhead enclosure shall be built in the hatchways from the over deck of the lower hold to the weather deck forming a tight enclosure to prevent sulfur dust entering the tween decks during loading. (b) Holds shall be cleaned of all debris. (c) Ceiling shall be made tight to prevent sulfur dust finding its way into the bilges; any chinking necessary in the way of tank tops or bilges shall be with non-combustible material. (d) In order to minimize the movement of fine sulfur dust, cowl ventilators serving the hold into which sulfur is being loaded or discharged shall be blanked off to prevent circulation of air. (e) "No Smoking" signs shall be conspicuously displayed, and the officer in charge shall ensure that they are observed. (f) An oxygen breathing apparatus, or proper gas mask, shall be made readily available. (g) A fire hose, preferably supplied with fresh water from a shore supply source, shall be available at each hatch through which sulfur is being worked. (h) Upon completion of loading, the sulfur shall be leveled off and the sulfur dust deposited during the process of loading, being extremely inflammable, shall be cared for by sweeping or washing it down. This applies to the decks and to the overhead structure within the holds. (1) After unloading, all residue of sulfur or sulfur dust shall be thoroughly cleaned out of cargo holds before loading other cargo therein. (k) When sulfur is loaded by metal chute method, provision shall be made for proper grounding of the chute, using flexible cable to prevent static discharge.

(E) The vessel's officer assigned to supervise the receipt of such tank cars on board the vessel shall personally check each requirement and make an entry in a record book specifically provided for such purpose stating all conditions are found to be satisfactory and give the car initials and number. (F) Tank cars found not to be satisfactory shall be refused transportation and an entry made in the record book noting such rejection and reason, together with identification of the car. Rejection reports shall be forwarded to the nearest Officer in Charge, Marine Inspection. Not permitted..... NOTE: Ferry stowage (AA).. Ferry stowage (BB).

(B) Provided dome covers are securely fastened in place. (C) Provided all valves in piping to tank are tightly closed. (D) Provided there is no leakage from pipe lines or any other part of tank. (E) Provided no excess residue of a previous lading is adhering to any exterior part of the tank or vehicle. (F) The person assigned to supervise the receipt of such tank vehicles on board the vessel shall personally check each requirement. (G) Vehicles found not to be satisfactory shall be refused transportation and an entry made in the record book noting such rejection and reason, together with an identification of the vehicle. Rejection reports shall be forwarded, to the nearest Officer in Charge, Marine Inspection. May be accepted on permitted vessels provided: (B) All valves are tightly closed.
