Some suggestions for personal security are to encourage security awareness in the family; be alert of suspicious persons; vary personal routines; and know surroundings inside and outside the home. Security for children includes traveling in groups or pairs; avoiding isolated areas; refusing to accompany strangers; and never leaving children home alone. Suggested methods to deter intruders are burglar proofing the home; screening all household help; keeping valuables out of sight; and teaching children how to call the police. Precautions for hotel security include keeping the room key in possession at all times; being observant of suspicious persons; not giving the room number to anyone; and knowing where emergency exits are located. Residential arson precautions include two exits for every room; having smoke detectors installed; and making sure the family knows the escape routes. Transportation precautions include ensuring that the vehicle is in good repair; locking doors and keeping windows closed; and traveling on busy routes. In the event of a bomb threat, stay calm and be courteous, do not interrupt, keep the caller on the line as long as possible, report the threat immediately, and evacuate the threatened area. Mail bomb precautions include not accepting packages without a return address; looking for smudge marks or oil; misspelling of the title; and not opening the package if there is excessive sealing material. If it is suspected that a letter or package contains questionable or hazardous material, evacuate the immediate area; contact the local police; shield the body from the object; wash hands with soap and water; contact the Federal Bureau of Investigation; and do not further handle the letter or package. For hostage survival, precautions include to not attempt to flee on foot; stay calm and be alert; comply with the instructions of the abductors; and avoid making provocative remarks.
