Study Notes

Forcible Entry Overview

Historical context: Many homes were left unlocked until the 1950s, leading to increased need for security and advanced entry techniques for firefighters.
New locking devices emerged, increasing resistance to forced entry, requiring firefighters to adapt tools and procedures.
Traditional tools used by firefighters have evolved; Halligan tools and sledgehammers are now common in addition to older methods.

Entry Techniques and Considerations

A variety of forcible entry methods exist, including brute-force techniques and alternative methods like hydraulic tools and cutting devices.
The choice of entry method depends on urgency, door type, available tools, and acceptable damage.
Prompt and efficient entry is crucial to save lives and control fire spread.

Maintaining Door Integrity

Preserving door integrity is essential to control fire behavior and oxygen supply; breaking glass can lead to backdrafts.
Firefighters must keep doors closed to limit fire spread, especially those that lead to stairways or escape routes.

Forcible Entry Size-Up

Size-up begins with alarm details and involves assessing time of day, occupancy type, and the nature of doors (inward vs outward).
Knowledge of traditional door behaviors is vital; most residential doors open inward, while commercial doors typically open outward.
Firefighters should assess visible fire presence near the entry point to prepare accordingly.

Door Construction and Security Indicators

Recognizing door construction and security features influences entry method; locking devices positioned far from door edges indicate stronger security measures.
Outward-opening doors typically lead to janitorial spaces or elevators, necessitating caution.

Conventional Forcible Entry

Conventional entry employs brute force to bypass locks or damage door structures; it emphasizes tool leverage and fulcrum mechanics.
The Halligan tool, paired with a flat-head axe or sledgehammer, is effective due to its versatility in different scenarios.

Inward-Opening Door Techniques

To breach inward-opening doors, position the Halligan tool above or below the lock and utilize the correct angle for leverage.
Team coordination is critical; approaches involve driving the tool into the door while managing safety to prevent accidental injury.

Forcing Doors: Process Steps

Secure the Halligan tool, apply force towards the door while ensuring it doesn't open uncontrollably, minimizing risk of fire escape.
Use proper positions on each side of the tool for added control and safety during the exertion of force.

Control During Entry

It's crucial to manage the door's opening once the tool is in place; a controlled entry prevents sudden flame outbreaks.
Firefighters should utilize a hose strap or hold the doorknob to maintain control over the door as it opens, allowing for better management of fire conditions behind the door.
