SOURCE: The provisions of this Subpart 146.03 contained in Order 74, 6 F.R. 259, Jan. 11, 1941, unless otherwise noted.

§ 146.03-1 MIN.

The letters "MIN" refer to "Marine Inspection and Navigation", a former Bureau in the Department of Commerce whose functions are now carried out by the Coast Guard.

[CGFR 62-11, 27 F.R. 5280, June 5, 1962]

§ 146.03-3 Bulk.

The word "bulk" means substances which are loaded and carried on board a vessel without benefit of containers or wrappers, and received and delivered by the vessel carrier without mark or count: Provided, however, That this definition does not apply to initiating or priming explosives.

§ 146.03-4 Carfloat.

A carfloat is a vessel that serves as an extension of a rail line or highway over water. It includes those vessels in other than ocean, coastwise or ferry services having provisions only for "On deck" stowage of vehicles, operates on a short run, and differs from a ferry service in that it operates on an irregular basis and may serve several points in a port area. [CGFR 67-23, 32 F.R. 8149, June 7, 1967] § 146.03-5

Cargo.

The initials "CFC" refer to Consolidated Freight Classification.

§ 146.03-7 Character of vessel.

The term "character of vessel" means the type of service in which the vessel is engaged at the time of carriage of the explosives or other dangerous articles or substances subject to the regulations in this part, i.e., a cargo vessel, a passenger vessel, a ferry vessel, a railroad car ferry or a barge.

§ 146.03-8 Dangerous articles defined.

A dangerous article within the meaning of the regulations in this subchapter is an article falling within any of the following classifications:

Explosives.

Inflammable Liquids.

Inflammable Solids and Oxidizing Materials. Corrosive Liquids.

Compressed Gases.
Poisons.

Radioactive Materials.
Hazardous Articles.

Ships' Stores and Supplies of a Dangerous Nature.

For definitions covering these classifications see the appropriate section within this subchapter. These are §§ 146.19-1, 146.20-1, 146.20-11, 146.21-1, 146.22-1, 146.23-1, 146.24-1, 146.25-1-146.25-15, 146.27-1, and 147.02-1, 147.02-2. Combustible Liquids are defined in § 146.26-1. [CGFR 68-142, 84 F.R. 2086, Feb. 12, 1969] § 146.03-9 Flammable or inflammable.

For the purpose of the regulations in this subchapter, the words "inflammable" and "flammable," are interchangeable or synonymous terms.

[CGFR 51-19, 16 FR. 7212, July 24, 1951] § 146.03-10 Explosive range.

The vapors of inflammable liquids (and to a lesser extent of combustible liquids) when mixed with air will in proper proportions form an explosive concentration. The low or "lean" limit and the high or "rich" limit vary in accordance with the characteristics of the liquid involved. The mixture or percent by volume between the "lean" and the "rich" mixtures is termed the "explosive range". Any percentage of the vapor in air between these limits will be likely, upon ignition, to continue to burn with rapidity and violence, sometimes with explosive effects.

This phrase is used to describe organic material such as charcoal, peat moss, sugar, sulfur, sawdust, powderous materials such as flour, granular materials such as seeds, grains, and cereals, or like substances.

§ 146.03-13 Fire point.

The term "fire point" denotes the temperature at which the vapors given off by the substance, if ignited, will continue to burn. The fire point is generally higher than the flash point, although occasionally they coincide as in the case of ether, carbon disulfide, and a few other substances.

The term "hermetically sealed" means perfectly closed or closed airtight by, or as by, fusion, or crimping, so that no gas nor vapor can enter or escape.

[Order 74, 6 F.R. 259, Jan. 11, 1941, as amended by Order 103, 6 F.R. 1893, Apr. 11, 1941) § 146.03-16 Holds gas tight.

This term means that the structural boundaries of the hold are free of openings and constructed sufficiently tight to withstand a gas pressure not in excess of 1 pound per square inch. A hold that will withstand a hose test without leakage may be assumed as being gas tight. Cargo or other openings in the structural boundaries of such holds (except over deck cargo hatches) shall be provided with tight closing means. Cargo hatch openings in the over deck provided with hatch covers and tarpaulins are accepted as satisfactory closing means for such compartment or hold.

[Order 74, 6 F.R. 259, Jan. 11, 1941, as amended by Order 103, 6 F.R. 1893, Apr. 11, 1941] § 146.03-17 ICC or DOT.

The initials "ICC" refer to Interstate Commerce Commission. The initials "DOT" refer to Department of Transportation. For the purposes of the regulations in this subchapter ICC and DOT are used interchangeably with respect to safety regulatory functions formerly performed by the Interstate Commerce Commission and now performed by the Department of Transportation pursuant to 49 U.S.C. 1657.

[CGFR 68-142, 34 F.R. 2086, Feb. 12, 1969] § 146.03-18 ICC and DOT regulations.

The terms "ICC regulations" and "DOT regulations" when used in the regulations in this part refer to regulations of the Interstate Commerce Commission (49 CFR Parts 71-90) or the Department of Transportation (49 CFR Parts 170-189) in effect at the time a shipment is moving and subject to the regulations in this part. The ICC regulations were redesignated as DOT regulations upon the establishment of the Department of Transportation pursuant to 49 U.S.C. 1657 effective April 1, 1967; therefore, references in this part to ICC
