Residential Tactical Use
The primary purpose for having pepper spray for protection in a residential setting is to create a barrier to prevent the intruder from getting inside. There are two types of barriers with two different and distinct functions. The interior barrier is created by spraying into an area of entry just prior to retreating to a "safe room" inside the residence. The door/window defense is similar to personal defense on the street. It is used on an intruder when he is entering, or is already in the residence.
Interior Barrier Defense
This defense is used if you become aware of an intruder still outside, in the act of breaking in, or if he is already in the residence. In order for this spray defense to work it is necessary to have a "safe room," an interior room such as a bedroom, bathroom, or a closet that can be securely locked and will resist break in by the intruder. It should also have a phone to call the police. If a break in is in progress or is imminent, spray the entry area the intruder must come through, then retreat to your safe room.
If there are children or others in the residence, gather them together in the safe room with you. Once there, be ready to spray anyone who breaks through the door. Don't go from your safe room for any reason as you don't know whether the intruder is armed, his mental state, or his intentions. Inside the safe room, don't wait directly in front of the door, but rather to the side of it, ready to spray anyone who enters.
