§148.2   Responsibility and compliance.
§148.3   Definitions.
§148.5   Alternative procedures.
§148.7   OMB control numbers assigned under the Paperwork Reduction Act.
§148.8   Incorporation by reference.
§148.9   Right of appeal.
§148.10   Permitted materials.
§148.11   Hazardous or potentially dangerous characteristics.
§148.12   Assignment and certification.

§148.1   Purpose and applicability.

(a) This part prescribes special handling procedures for certain solid materials that present hazards when transported in bulk by vessel.

(b) Except as noted in paragraph (c) of this section, this part applies to all domestic and foreign vessels in the navigable waters of the United States that transport bulk solid materials requiring special handling.

(c) This part does not apply to an unmanned barge on a domestic voyage carrying a Potentially Dangerous Material (PDM) found in Table 148.10 of this part. All barges on international voyages must follow the requirements for PDM.

(d) The regulations in this part have preemptive impact over State law on the same subject. The Coast Guard has determined, after considering the factors developed by the Supreme Court in U.S. v. Locke, 529 U.S. 89 (2000), that in directing the Secretary to regulate the safe transportation of hazardous material and the safety of individuals and property on board vessels subject to inspection, as well as the provision of loading information, Congress intended to preempt the field of safety standards for solid materials requiring special handling when transported in bulk on vessels.

§148.2   Responsibility and compliance.

Each master of a vessel, person in charge of a barge, owner, operator, shipper, charterer, or agent must ensure compliance with this part. These persons are also responsible for communicating requirements to every person performing any function covered by this part.

§148.3   Definitions.

As used in this part—

A-60 class division means a division as defined in §32.57-5 of this chapter.

Adjacent space means any enclosed space on a vessel, such as a cargo hold, cargo compartment, accommodation space, working space, storeroom, passageway, or tunnel, that shares a common bulkhead or deck with a hatch, door, scuttle, cable fitting or other penetration, with a cargo hold or compartment containing a material listed in Table 148.10 of this part.

Away from means a horizontal separation of at least 3 meters (10 feet) projected vertically is maintained between incompatible materials carried in the same hold or on deck.

Bulk applies to any solid material, consisting of a combination of particles, granules, or any larger pieces of material generally uniform in composition, that is loaded directly into the cargo spaces of a vessel without any intermediate form of containment.

Bulk Cargo Shipping Name or BCSN identifies a bulk solid material during transport by sea. When a cargo is listed in this Part, the BCSN of the cargo is identified by Roman type and is listed in Column 1 of Table 148.10 of this part. When the cargo is a hazardous material, as defined in 49 CFR part 173, the proper shipping name of that material is the BCSN.

Cold-molded briquettes are briquettes of direct reduced iron (DRI) that have been molded at a temperature of under 650 °C (1,202 °F) or that have a density of under 5.0 g/cm3;.

Commandant (CG-ENG-5) means the Chief, Hazardous Materials Division of the Office of Design and Engineering Systems. The mailing address is: Commandant (CG-ENG-5), Attn: Hazardous Materials Division, U.S. Coast Guard Stop 7509, 2703 Martin Luther King Jr. Avenue SE., Washington, DC 20593-7509; telephone 202-372-1420 or email hazmatstandards@uscg.mil.

Compartment means any space on a vessel that is enclosed by the vessel's decks and its sides or permanent steel bulkheads.

Competent authority means a national agency responsible under its national law for the control or regulation of a particular aspect of the transportation of hazardous materials.

Confined space means a cargo hold containing a material listed in Table 148.10 of this part or an adjacent space not designed for human occupancy.

Domestic voyage means transportation between places within the United States other than through a foreign country.

Hazard class means the category of hazard assigned to a material under this part and 49 CFR parts 171 through 173.

Hazardous substance is a hazardous substance as defined in 49 CFR 171.8.

Hold means a compartment below deck that is used exclusively for the stowage of cargo.

Hot-molded briquettes are briquettes of DRI that have been molded at a temperature of 650 °C (1,202 °F) or higher, and that have a density of 5.0 g/cm3 (312 lb/ft3) or greater.

IMSBC Code means the English version of the “International Maritime Solid Bulk Cargoes Code” published by the International Maritime Organization (incorporated by reference, see §148.8).

Incompatible materials means two materials whose stowage together may result in undue hazards in the case of leakage, spillage, or other accident.

International voyage means voyages—

(1) Between any place in the United States and any place in a foreign country;

(2) Between places in the United States through a foreign country; or

(3) Between places in one or more foreign countries through the United States.

Lower flammability limit or LFL means the lowest concentration of a material or gas that will propagate a flame. The LFL is usually expressed as a percent by volume of a material or gas in air.

Master means the officer having command of a vessel. The functions assigned to the master in this part may also be performed by a representative of the master or by a person in charge of a barge.

Material safety data sheet or MSDS is as defined in 29 CFR 1910.1200.

Person in charge of a barge means an individual designated by the owner or operator of a barge to have charge of the barge.

Potentially Dangerous Material or PDM means a material that does not fall into a particular hazard class but can present a danger when carried in bulk aboard a vessel. The dangers often result from the material's tendency to self-heat or cause oxygen depletion. Materials that present a potential danger due solely to their tendency to shift in the cargo hold are not PDMs. For international shipments prepared in accordance with the IMSBC Code (incorporated by reference, see §148.8), equivalent terminology to PDM is Material Hazardous only in Bulk (MHB).

Readily combustible material means a material that may not be a hazardous material but that can easily ignite and support combustion. Examples are wood, straw, vegetable fibers, and products made from these materials, and coal lubricants and oils. The term does not include packaging material or dunnage.

Reportable quantity or RQ means the quantity of a hazardous substance spilled or released that requires a report to the National Response Center. The specific RQs for each hazardous substance are available in 49 CFR 172.101, Appendix A.

Responsible person means a knowledgeable person who the master of a vessel or owner or operator of a barge makes responsible for all decisions relating to his or her specific task.

Seed cake means the residue remaining after vegetable oil has been extracted by a solvent or mechanical process from oil-bearing seeds, such as coconuts, cotton seed, peanuts, and linseed.

Shipper means any person by whom, or in whose name, or on whose behalf, a contract of carriage of goods by sea has been concluded with a carrier; or any person by whom or in whose name, or on whose behalf, the goods are actually delivered to the carrier in relation to the contract of carriage by sea.

Shipping paper means a shipping order, bill of lading, manifest, or other shipping document serving a similar purpose.

Stowage factor means the volume in cubic meters of 1,000 kilograms (0.984 long tons) of a bulk solid material.

Threshold limit value or TLV means the time-weighted average concentration of a material that the average worker can be exposed to over a normal eight-hour working day, day after day, without adverse effect. This is a trademark term of the American Conference of Governmental Industrial Hygienists (ACGIH).

Transported includes the various operations associated with cargo transportation, such as loading, off-loading, handling, stowing, carrying, and conveying.

Trimming means any leveling of a cargo within a cargo hold or compartment, either partial or total.

Tripartite agreement means an agreement between the national administrations of the port of loading, the port of discharge, and the flag state of the vessel, on the conditions of carriage of a cargo.

Ventilation means exchange of air from outside to inside a cargo space and includes the following types:

(1) Continuous ventilation means ventilation that is operating at all times. Continuous ventilation may be either natural or mechanical;

(2) Mechanical ventilation means power-generated ventilation;

(3) Natural ventilation means ventilation that is not power-generated; and

(a) General. When Column 5 refers to a code for a hazardous material or PDM, the meaning of that code is set forth in this section.

(b) Table of Hazardous or Potentially Dangerous Characteristics.

CodeHazardous or potentially dangerous characteristic
1Contact with water may cause heating.
2Contact with water may cause evolution of flammable gases, which may form explosive mixtures with air.
3Contact with water may cause evolution of toxic gases.
4If involved in a fire, will greatly intensify the burning of combustible materials.
5A major fire aboard a vessel carrying this material may involve a risk of explosion in the event of contamination (e.g., by a fuel oil) or strong confinement. If heated strongly will decompose, giving off toxic gases that support combustion.
6These mixtures may be subject to self-sustaining decomposition if heated. Decomposition, once initiated, may spread throughout the remainder, producing gases that are toxic.
7Toxic if swallowed and by dust inhalation.
8Harmful and irritating by dust inhalation.
9Highly corrosive to steel.
10Powerful allergen. Toxic by ingestion. Skin contact or inhalation of dust may cause severe irritation of skin, eyes, and mucous membranes in some people.
11May be susceptible to spontaneous heating and ignition.
12Liable to cause oxygen depletion in the cargo space.
13Liable to emit methane gas which can form explosive mixtures with air.
14Dust forms explosive mixtures with air.
15May present substantial danger to the public health or welfare or the environment when released into the environment. Skin contact and dust inhalation should be avoided.
16Combustible. Burns with dense black smoke. Dust may cause skin and eye irritation.
17Radiation hazard from dust inhalation and contact with mucous membranes.
18Susceptible to fire from sparks and open flames.
19May self-heat slowly and, if wet or containing an excessive proportion of unoxidized oil, ignite spontaneously.
20Fire may produce irritating or poisonous gases.
21Dust may contain toxic constituents.
22Lead nitrate and lead sulfide are hazardous substances; see code 15 of this table and §148.270.
