If someone comes to the door asking to use the phone for an emergency, offer to make the call for them, but don't let them come in. Request identification from all service repair staff and maintenance personnel. Check their credentials by calling the company they represent. In an apartment, call the manager. When showering in a residence hall or public type shower facility, have someone monitor the shower area or entrance.
Good lighting is a deterrent to crime.
If lighting is inadequate in an apartment or residence hall setting, report it to appropriate personnel. Do not give descriptive information about yourself, your family, or your neighbors. Never mention or advertise that you may be alone or live alone. List your last name and first initial only on your mailbox, front door and telephone book. Consider adding a fictitious name or names on your mailbox in addition to your own.
