7. Keep open wounds and burns as clean as possible. Avoid touching open wounds and burns with your hands or unsterile objects unless no sterile dressings are available. 8. Do not try to give liquids to an un- conscious  person. 9. Never give morphine to an unconscious person. 10. Do not move a patient until the extent of the injuries has been determined. NUCLEAR WEAPONS ACCIDENT/INCIDENT Nuclear weapons systems have built-in safety features and are governed by safety rules during all operational phases. As a senior petty officer, you must recognize, however, that hazards do exist. You must know what to do in the event of a nuclear weapon accident/incident. In the United States, nuclear weapons maybe transported by aircraft, trucks, trains, or naval ships. In each case, weapons and components are installed in special containers that are securely fastened to the transport vehicle by carefully designed tie-downs and mountings. Because principal methods and procedures related to nuclear weapons accident/incidents are classified, only basic information will be covered here. More detailed information can be found in the Repair Party Manual (COMNAVSURFLANTINST 3541.lC/COMNAVSURFPACINST 3541.4B). Even though nuclear weapons are designed to prevent a nuclear yield in the event of accidental detonation, a possible hazard is still associated with conventional weapons and material. The two components of a nuclear weapon that constitute the most probable hazard in the case of an accident are high explosives and plutonium. HIGH EXPLOSIVES Most nuclear weapons contain high explosives in varying amounts of up to 200 pounds. These high explosives present a major hazard. Treat accidents or fires involving nuclear weapons the same as those involving conventional high explosives. If a nuclear weapon is involved in a fire, the high explosives could detonate. Detonation may be very small or of considerable magnitude. If a nuclear weapon accident occurs, only personnel trained in high-explosive disposal should attempt to clean up, recover, or dispose of the high explosives. PLUTONIUM Plutonium may become dispersed as small particles as the result of impact, detonation of the high explosives, or by smoke if a fire occurs. Plutonium is a hazard only if it enters the body. When small particles of plutonium are suspended in the air, the particles can be inhaled into the lungs or swallowed. Plutonium particles may also enter the body through cuts in the skin. RESPONSE TO A NUCLEAR WEAPON ACCIDENT/INCIDENT Execute a shipboard nuclear accident/incident in the same manner as any shipboard general emergency. In port, if less than the entire crew is aboard and if the situation warrants, sound general quarters. Sound general quarters at sea and the appropriate repair locker/damage control team takes charge. If you are the first person on the scene, pass the alarm; then rig any available fire hose and start cooling the warhead with high velocity water fog. Do not use foam on warheads, as it acts as an insulator and causes heat retention rather than cooling. If you are caught in the area of a fire or an explosion, obtain some type of respiratory protection, even if it is a handkerchief placed over the nose and mouth. An explosion may result in scattered, burned, or melted explosives in the area. High explosives in this form are especially susceptible to shock or movement. They may be recognized by their tan or buff color in their original form, a pink color when fused, or a white powdery appearance when burned. Remember, stay away from high explosives. CBR DEFENSE CBR defense is defined as all damage control and personnel protective measures used to combat/ minimize the effects of chemical, biological, or radiological attack. CBR defense measures may be invoked to counter a direct enemy attack or to counter the effects of the use of CBR weapons by friendly forces in defending themselves. In studying CBR defense, remember that new approaches are constantly being tested—new weapons are being developed and new protective and defense measures are being established. Keeping up to date with new developments is therefore particularly important in the field of CBR  defense. 7-19
