Forcible Entry - Lock Cutting

In a disaster you may have a need to cut a lock off, or enter a steel door. The simplest way is to use a good-quality battery-operated grinder with a 1/8 inch cut-off wheel.  These are great to carry on an ambulance or ESU vehicle. You can sip through an Onguard, a Knog, or a Kryptonite bicycle lock in two minutes. "Poof!"  And cut through an American Lock, a chain-link fence, a security grid on a window, or handcuffs. To enter an apartment with a thin steel door, cut a square to reach in with your hand and release the lock from inside. The little grinders can cut through an automobile post such as supports a windshield. Keep extra batteries charged.

Another good use for the battery-operated abrasive wheel is to cut a chain or cable blocking an access road. It is common to use these in housing projects, parks, and fire-roads. Large Fire-Rescue vehicles have heavy equipment to do so but a single ambulance may respond without the capacity for such equipment. If you have to go through a chained road and need to break the chain (and have no cut-off wheel), turn the vehicle around so the back of the vehicle faces the chain. Accelerate backwards at ten miles per hour and the force of the vehicle hitting the chain will break it. Do not use the front because the chain may over-ride the hood or smash your headlights.
