    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.
