• Be cautious when working in voids or unvented spaces.• Beware the dangers of working aloft. Never attempt to stop a rotating antenna manually.• Keep protective closures, fuse panels, and circuit breaker boxes closed unless you are actuallyworking on them.• Never bypass an interlock unless you are authorized to do so by the commanding officer, andthen properly tag the bypass.• Use extreme caution when handling cathode-ray tubes. They implode violently if broken. Theanode contact may have a residual electrical charge. Make sure you discharge the anode beforehandling.You can find additional and more detailed information on safety in the Electronics Installation andMaintenance Book (EIMB), General, NAVSEA SE000-00-EIM-100, paragraph 3-4. Another excellentreference source is the <strong>Naval</strong> Electronics Systems Command's Electronic Safety <strong>Handbook</strong>, E0410-AA-HBK-010/00K ELEXSAFE.FIRST AIDFirst aid is the emergency care you give to sick or injured persons. It consists only of providingtemporary assistance or treatment until medical help is available. In addition to knowing what to do for avictim, you should also know what not to do.This section should be used to reinforce the knowledge you already have about first aid. First aid isincluded in detail for the purposes of review, study, and ready reference.First aid study classes are usually available through your medical department or the American RedCross.Your knowledge of first aid measures and their proper application may mean the difference betweenlife and death, between rapid recovery and long hospitalization, or between temporary disability andpermanent injury.The objectives of first aid are to save life and prevent further injury. First aid is not a substitute,however, for proper medical treatment. Keep in mind the objectives of first aid. Everyone in the Navymust know when and how to apply first aid measures and must be prepared to give assistance to personsinjured in battle, collision, fire, or accidents.In administering first aid, you have three primary tasks:• Maintain breathing• Stop bleeding• Prevent or reduce shockThe first step, of course, is to determine the extent of the victim's injuries. When you treat a victim,first consideration usually must be given to the most serious injury. In general, the order of treatment is torestore breathing, stop bleeding, and treat for shock.Work quickly, but do not rush around frantically. Do not waste time looking for ready-madematerials; do the best you can with whatever is at hand. Send for medical help as soon as possible.1-2
Although each case involving injury or sickness presents its own special problems, the followinggeneral rules apply to practically all situations. Become familiar with these basic rules before you go on tofirst aid treatment for specific types of injuries.1. Keep the victim lying down, head level with the body, until you have found out what kind ofinjury has occurred and how serious it is. If the victim shows one of the following difficulties,however, follow the rule given for that specific problem:a. Vomiting or bleeding about the mouth and semi-consciousness. If the victim is in danger ofsucking in blood, vomited matter, or water, place the victim on his/her side or back with thehead turned to one side and lower than the feet.b. Shortness of breath. If the victim has a chest injury or breathing difficulties, place the victimin a sitting or semi-sitting position.c. Shock. If the victim is in shock, place the person on his or her back with the head slightlylower than the feet.2. Move the victim no more than is absolutely necessary. To determine the extent of the victim'sinjuries, carefully rip or cut the clothing along the seams. If done improperly, the removal of thevictim's clothing could cause great harm, especially if fracture injuries are involved. When theclothing is removed, ensure that the victim does not become chilled. Shoes may also be cut off toavoid causing pain or increasing an injury.3. The victim need not see the actual injury(ies). You can supply reassurance and make the victimmore comfortable by ensuring him or her that the injuries incurred are understood and medicalattention will be given as soon as possible.4. Do not touch open wounds or burns with fingers or other objects, except when sterile compressesor bandages are not available and it is absolutely necessary to stop severe bleeding.5. Do not try to give an unconscious person any solid or liquid substance by mouth. The personmay vomit and get some of the material into the lungs when he or she breathes, causing chokingand possibly death.6. If a bone is broken, or you suspect that one is broken, do not move the victim until you haveimmobilized the injured part. This may prove life saving in cases of severe bone fractures orspinal cord injuries, because the jagged bone may sever nerves and blood vessels, damagetissues, and increase shock. Of course, threat of fire, necessity to abandon ship, or other similarsituations may require that the victim be moved. But the principle that further damage could bedone by moving the victim should always be kept in mind and considered against other factors.7. When transporting an injured person, always see that the litter is carried feet forward no matterwhat the injuries are. This will enable the rear bearer to observe the victim for any respiratoryobstruction or stoppage of breathing.8. Keep the injured person comfortably warm — warm enough to maintain normal bodytemperature.Very serious and mutilating injuries may require heroic first aid measures on your part. However, thegreater the number of injuries, the more judgment and self-control you must exhibit to prevent yourselfand well-intentioned bystanders from trying to do too much.1-3
