Rescue from difficult and dangerous situations requires quick, sure action. In an emergency, every moment counts, and the steps taken may make the difference between saving or losing lives and property.
   People react differently to emergencies. But everyone realizes that there is little time to think when people are in trouble. Every individual should know the basic rules of first aid so that he will have this information to guide his actions when necessary. It is also important to keep handy the telephone numbers of various agencies, including the fire department and the police.
   In case of disasters, such as floods, earthquakes, tornadoes, and shipwrecks, the resources of an entire nation are often called into action.
