Storage

To decrease hazards in handling, rocket bodies and motors are generally shipped and stored separately. Motors with large grains are kept in a non-propulsive state until final assembly is necessary. The seals at both ends of the motors are light and easily displac-ed by pressure developed inside the tube. Should the igniter and grain ignite, the closu-res would fail quickly, relieving the pressure without more than a slight movement of the motor,

It is necessary that loaded motors be kept at moderate temperatures as much as possible. Even though spontaneous ignition should not take place, the powder should not be stored where temperatures exceed 100° F, because such conditions tend markedly to decrease the stable life of the propellant. Because of the electric squib, rocket motors should not be stored near radio apparatus or antenna leads.

Although there is very little possibility of a motor firing as a result of falling or rough handling, such treatment is likely to cause malfunctioning of the rounds. Ammunition should be kept in packing containers or ready boxes and should not be handled in a loose condition unless necessary.
