hands of the supervisor and the personnel who maintain them. The quality and reliability of an ejection system are largely dependent on the supervisors and the mechanics who maintain the systems. Because the safety precautions presented in this chapter are basic and general in nature, you should consult other publications for the specifics related to the task at hand. Smoking Smoking must be prohibited in any magazine, building, vehicle, or other conveyance or area containing explosives or ammunition; where operations involving such material are conducted; and in the immediate vicinity of handling or loading operations involving explosives or ammunition. Smoking areas maybe designated by the commanding officer. Magazines Naked lights, matches, lighters or other spark, flame, or heat-producing devices must NEVER be taken or stowed in magazines or other areas containing explosives. Cartridges If a cartridge is removed from a cartridge- actuated device, it should be marked for identification so it can be reinstalled in the same device. A deformed or dented cartridge or CAD might not fit properly in the equipment for which it was designed; therefore, in handling, special care must be exercised to prevent them from being struck or dropped. Assistance Under no circumstances should any person reach within or enter an enclosure for the purpose of servicing or adjusting explosive equip- ment without the immediate presence or assistance of another person capable of rendering aid. Contamination Operational activities must not apply anti- corrosive materials to CADs. When anticorrosive material is being applied to any item in the vicinity of CADs or associated equipment, every pre- caution will be exercised to prevent contamina- tion of the CADs or associated equipment. Contamination of CADs can have a detrimental effect on the function of the system. Shock Electrically initiated cartridges must be kept away from stray electrical currents. Under certain conditions, dangerous potentials can be stored in circuits after the power source has been dis- connected because of charges retained by capacitors. To avoid casualties, you should always disconnect the power source and discharge and ground circuits prior to touching them. Reporting All malfunctions, discrepancies, and accidents involving CADs must be reported by message to NAVORDSTA, Indian Head, Maryland in accordance with OPNAVINST 4790.2. If the suspected defect is with the CAD, the message must be addressed to NAVORDSTA for action. If the report describes an inadvertent actuation of an aircraft system resulting in the CAD functioning normally, the action copy of the report must be submitted to the cognizant field activity (CFA) for the aircraft with an informa- tion copy to NAVORDSTA, Indian Head, Maryland. Accidents and incidents involving CADS may require reporting in accordance with OPNAVINST 3750.6 in addition to the OP- NAVINST 4790.2. Submission of the reports required by the maintenance instruction does not satisfy the requirements of the safety instruction. If dual reporting is required, you should ensure the reports are adequately cross-referenced to satisfy the requirements of all commands involved. All CADs suspected of being inconsistent, of malfunctioning, or of being involved in an accident or incident must be clearly identified and turned in to the station or ship’s ordnance or weapons department. Mark the item “hold for 30 days for engineering investigation (EI) pending disposition instructions.” The report should contain the turn-in document number and identify the activity holding the material. If CFA response is requested, NAVORDSTA will respond with complete disposition and shipping instructions. If a response is not received within 15 days, a follow-up message must be sent to NAVORDSTA to verify their receipt of the original report. All cartridges and cartridge-actuated devices must be handled as live ammunition. Cartridges or cartridge-actuated devices that have been fired 2-31
