Characteristic properties, cautions, markings required

Jet thrust units (jato) are metal cylinders containing a mixture of chemicals capable of burning rapidly and producing considerable pressure. Jet thrust units are designed to be ignited by an electric igniter. They are used to assist airplanes to take off.

Rocket motors are devices containing 8 propelling charge and consisting of one or more continuous type combustion units, closed at one end (closure may be an igniter with a thrust plate) and with one or more nozzles at the other end. The propelling charge consists of a mixture of chemicals which when ignited is capable of burning rapidly and producing considerable pressure and which will not sustain a detonation. (The rocket motor carries its own solid oxidizer-fuel combination). Rocket motors are designed to be ignited by an electrically actuated device which may be an igniter, or by other means. They are used to propel or provide thrust for guided missiles, rockets, or spacecraft. Igniters are devices consisting

of an electrically operated or remotely controlled ignition element and a fast burning composition which functions by rapid burning rather than detonation, assembled in a unit, for use in igniting the propelling charge of jet thrust units, rocket motors, or rocket engines.

Jet thrust units, Class B explosives, or rocket motors, Class B explosives, must not be shipped by, for, or to the Department of the Army, the Department of the Navy, or the Department of the Air Force. Jet thrust units, Class B explosives, or rocket motors, Class B explosives, may be packaged in the same outside packaging with their separately packaged igniters (or igniter components), Class A, B or C explosives, only in packagings approved by the Commandant, U.S. Coast Guard of approved military specifications complying with 49 CFR 173.7(a).
