Toy paper caps consist of paper cap ammunition for toy pistols, in sheets, strips, rolls or individual caps. Toy propellant devices and toy smoke devices consist of small paper or composition tubes or containers containing a small charge of slow burning propellant powder or smoke producing powder. Do not stow in the same compartment or hold with inflammable liquids, infiammable solids and oxidizing materials, corrosive liquids or inflammable gases. Each outside container shall be plainly marked: "Toy caps-Handle carefully", "Toy propellant devicesHandle carefully" or "Toy smoke devices-Handle carefully" as the case may be.

(a) An inflammable (flammable) liquid is defined by the ICC regulations as any liquid which gives off inflammable (flammable) vapors (as determined by flash point from Tagliabue's open-cup tester, as used for test of burning oils) at or below a temperature of 80° F.

(b) Such definitions are binding upon all shippers making shipments of inflammable (flammable) liquids by common carrier vessels engaged in interstate or foreign commerce by water. These definitions are accepted and adopted and form part of the regulations in this subchapter applying to all shippers making shipments of inflammable (flammable) liquids by an vessel, and shall apply to the owners, charterers, agents, master or other persons, transporting, carrying, conveying, storing, stowing or using inflammable (flammable) liquids on board any vessel subject to R.S. 4472, as amended (46 U.S.C. 170), and the regulations in this subchapter.

[CGFR 57-33, 22 F.R. 8581, Oct. 29, 1957] $146.21-10 Export shipments of inflammable liquids.

Certain inflammable liquids are permitted by these regulations to be exported under shipping names differing from shipping names as required in domestic transportation. Such substances together with these "synonym” shipping names are indicated in the tables in § 146.21-100 and the "synonym” shipping names that are permitted are shown thereon. Substances shipped under these "synonym" shipping names may be accepted on board vessels that are permitted to transport such substances in export; provided the shipment otherwise conforms to the provisions of the regulations in this part. Stowage on board vessels shall be in accordance with the stowages indicated in the tables for the particular character of vessel involved. [CGFR 51-19, 16 F.R. 7219, July 24, 1951]

§ 146.21-15

Stowage on board vessels.

(a) All inflammable liquids permitted for transportation on board vessels shall, when taken on board a vessel, be stowed in accordance with the provisions applying to the particular character of vessel as shown in the tables, § 146.21-100, and with the detailed regulations of stowage shown in this subpart.

(b) ICC specification portable tanks, not over 20,000 pounds gross weight and ICC specification tank cars and motor vehicle tank trucks approved for the commodity carried and permitted transportation on board vessels by § 146.21100 shall be stowed in the specific location provided by § 146.21-100. The conversion table 46 CFR 146.07-40 (c) does not apply.

§146.21-20 "On deck" stowage.

(a) Inflammable liquids, stowage of which is permitted "On deck" by the provisions of the table § 146.21-100 shall be properly secured, when so stowed, in a manner satisfactory to the master or other person in charge of the vessel consistent with the following conditions:

(1) Such inflammable liquid shall be so stowed as to provide safe access to the crew's quarters and to all parts of the deck required to be used in the navigation and necessary working of the vessel.

(2) Such inflammable liquids shall not be stowed within a distance in a horizontal plane of 25 feet of an operating or embarkation point of a lifeboat when such point is at the same deck level as that upon which an inflammable liquid cargo is stowed, except on a vessel which by reason of its breadth, it is impossible to provide such horizontal distance; deck stowage is permitted when the cargo is confined to only one side of the center line of the vessel.

(3) Fire plugs, sounding pipes and access to same shall be maintained free and clear of inflammable liquid cargo stowed "On deck."

(b) on passenger-carrying vessels, when limited stowage of inflammable liquid is permitted "On deck", such liquids shall be stowed well away from any deck or spaces provided for use of passengers.

(c) The fire hose at each fire hydrant on the vessel in the vicinity of inflammable liquids stowed "On deck" shall be fitted with an approved combination spray nozzle. During loading and unloading operations, the pressure shall be maintained in the fire mains. Two hand portable fire extinguishers of the dry chemical type of at least 15 pounds capacity or two portable 22-gallon foam type extinguishers are also required and shall be located so as to be accessible in the event of fire occurring in the vicinity of such inflammable liquid cargo. Any foam used shall be of a type suitable for use with the lading.

(d) When portable tanks, tank cars and motor vehicle tank trucks containing inflammable liquids are stowed as permitted by the regulations in this subpart, the area in way of each 21,000 U.S. gallons or less of inflammable liquids shall also be protected by one or more B-V semiportable foam (40-gal. capacity) or dry chemical (100 lbs. minimum capacity) fire extinguishers, or alternatively, by a fire hose fitted with an approved portable mechanical foam nozzle with pick-up tube and two 5-gallon cans of foam liquid concentrate. When carrying commodities incompatible with the conventional foam system, the foam shall be of a type suitable for use with the lading. The fire extinguishers shall be located so as to be accessible in the event of fire occurring in the vicinity of these portable tanks.

§ 146.21-25 "Under deck” stowage.

(a) Stowage of inflammable liquids "Under deck" shall be either in ventilated holds or in holds that are gastight.

(b) Inflammable liquids that are permitted by the regulations in this subpart to be stowed in a cargo hold or a compartment on board a passenger vessel shall not be so stowed unless the compartment or hold authorized for such stowage is fitted with either an overhead water sprinkler system, inert gas or steam smothering system.

(c) Inflammable liquids permitted on passenger vessels may be stowed in a hold or compartment the overdeck of which forms a boundary of a passenger space, provided such overdeck is of an AI type of construction or in lieu thereof is fitted on its underside in way of the passenger area with three inches of incombustible insulation.

(d) Compartments or holds in which inflammable liquid cargo is to be stowed and which are fitted with electrical circuits having outlets within the compartment or hold shall have such circuits disconnected from all sources of power supply unless the fixtures within the hold are of explosion proof type, and such circuits shall not be again connected for power until the compartment or hold has been freed of any accumulation of inflammable vapors.

(e) After the stowage of inflammable liquid cargo has commenced in a compartment or hold that is not fitted with explosion proof type of electrical outlets no portable means of artificial lighting shall be used within such a compartment or hold unless such portable equipment is of the explosion proof type. Electrical connections for permitted portable lighting shall be made to outlets located outside of the compartment or hold and above the weather deck. Hand flashlights shall be of the non-sparking type.

(f) Inflammable liquids may be stowed in a compartment having a boundary bulkhead or deck which also forms a boundary to a boiler room, engine room or a coal bunker or galley provided no containers of such inflammable liquid are stowed within twenty (20) feet of such bulkhead or deck. When the amount of such inflammable liquid to be stowed in the hold exceeds the space

available the twenty (20) feet separation need not be complied with provided one or more of the following protections are provided:

(1) The bulkhead or deck is insulated with at least three (3) inches of insulation throughout its entire area subject to heat.

(2) A temporary wooden bulkhead of at least two inches thickness is constructed in the hold at least three inches off the engine room and six inches off the boiler room bulkhead and covering the entire area of the bulkhead that is subject to heat.
