The best security system begins with you and every resident in the community. Don't hesitate to check credentials by telephone before you allow a stranger or maintenance person to enter your apartment or house. Before you open your door, ask the caller to identify himself or herself. If you do not know the person, insist he or she produce positive identification before you permit entry. Your cooperation in this effort will make your living environment more pleasant, safe and secure.
Smoke detectors are an excellent early warning system.
Both are effective. Tampering with smoke alarms, fire extinguishers and other emergency equipment is strictly prohibited. Anyone who disregards fire regulations creates an extremely hazardous environment for other tenants as well as yourself. Everyone in the house should know how to use them. Fire extinguishers are easily maintained by checking them monthly to be sure each unit is holding its charge.
