Study Notes

Breaching Doors

Use breaching methods as a last resort to preserve door integrity.
Delays in water access can prevent quick closure of breached doors.
Avoid crawling through central parts of doors and knocking out frames.
Start breaching from the top hinge to manage venting heat, smoke, and fire.
Most commercial doors are designed to open outward as per exit codes.
Apply outward force while spreading the door from the jamb.

Opening Recessed Doors

For recessed doors, leverage the adze end of a Halligan tool.
Drive the adze between the door and jamb on the lock side for pulling leverage.
Position the adze 6 inches above or below the lock for effective force application.
Avoid inserting the adze more than the thickness of the door to prevent jamb damage.
Pry up or down if needed to assist the adze.

Forcing Metal Gates and Roll-Up Doors

Security gates are increasingly common due to rising thefts.
They may be difficult to identify when businesses are open due to storage methods.
Gates classified into manual, mechanical, and electrical types.

Forcing Gates

Methods to force gates depend on locking devices and securing mechanisms like padlocks.
Mechanical gates often have restricted access due to shielded raising/lowering chains.
Remove padlocks to expose chains, enabling gate lifting.
Manual gates require removal of gate keys or slide bolts to open.

Padlocks Overview

Padlocks can be categorized into low and high security.
Low-security padlocks are small and easily forced or cut with tools.
High-security padlocks are case-hardened, making them resistant to cutting.
Use bolt cutters (36 inches or longer) for high-security locks, with potential need for assistance due to strength requirements.

Lock Breaking Techniques

Using a duckbill lock breaker can effectively open high-security padlocks by splitting the bow.
A miner's pick can also serve as a low-cost alternative to commercial lock breakers.
Basic forcible-entry tools, like the Halligan, can shatter some locks through twisting at the bow.
Ensure sufficient tool length for adequate leverage during the lock-breaking process.
