Note

At time of manufacture, warheads, motors and fuzes are made as nearly waterproof as practicable.

g. Do not remove such relatively delicate items as proximity fuzes from hermetically sealed containers until just prior to assembly of fuze to rocket.

h. Do not remove separately packed igniters from their packings, and do not break moisture resistant seals until unit is to be used.

i. Do not place complete round on its tail. This may damage fins or electrical connections. If necessary to stand round on end, point nose downward, so that it would bury itself in the ground if ignited accidentally.

j. Handle rocket motor or packings that contain rocket motors gently. Rough handling may damage components and create hazards. Cracked and broken propellant, for example, can cause dangerous pressures in motors when fired.

k. Prevent extraneous electrical currents (such as static) or induction by electromagnetic radiation (from such sources as high-amperage circuits and transmitters) from igniting rockets.

Section XII. FIRING

5-29. General a. Where requirements call for application of electrical energy to the igniter circuit of a rocket for testing continuity (such as during manufacture, renovation, or preparation for shipment), the testing devices used must be approved by the engineering agency responsible.

b. To provide for safety of personnel, select areas for these operations which are remote from sources of electrical currents, which might result in accidental ignition of the rocket.

c. Do not conduct continuity testing of circuits in rockets in ground launchers immediately prior to firing, or in rockets positioned on aircraft launchers immediately prior to takeoff, except under authority of, and with testing equipment approved by, the chief of the technical service concerned.

5-30. Special Precautions a. Do not permit personnel to remain in triangular area directly behind rocket, where backblast occurs, unless they are protected by adequate shelter.

b. Always protect eyes when firing. Protect face and hands when firing at temperatures below freezing.
