Study Notes
Door Security Systems Overview
- VPS system features heavy steel doors that are tightly fastened to the building, requiring a metal-cutting saw for entry.
- Locking mechanisms include color-coded push-button locks, skeleton key locks, and interior deadbolts for secondary exits.
- Color-coded push-button locks can be breached by cutting a triangular hole to reach the internal catch, while skeleton key locks provide more security.
- Secondary egress doors can be accessed from the inside with simple handles but are not visibly indicated from the exterior.
Tools for Dealing with Bars
-
Battery-Powered Rebar Cutter
- Weighs 14 lbs, capable of cutting 5/8-in bars in about 3.3 seconds.
- Features a rotating head for flexible positioning and can be operated with one hand.
- Standard issue for every FDNY ladder, rescue, and squad company.
-
Angle Grinder
- Lighter alternative for cutting light steel bars but slower than rebar cutters.
- Cutting disks are brittle and susceptible to damage, particularly when impacted during transport.
-
Battery-Powered Angle Grinder
- Weighs over 6 lbs, lighter compared to rebar cutters, often carried by fire personnel.
- Disks can shatter easily, emphasizing the need for protective storage solutions.
Exothermic Torch
- Burns at temperatures exceeding 5,000°F, capable of cutting through heavy steel materials such as bar, I-beams, and thick plates.
- Operates with a hollow steel rod pressurized with pure oxygen, allowing for rapid cutting.
- Generates significant sparks and flames, necessitating safety precautions during use.
KnoxBox System
- A security solution where a vault containing building keys is mounted on the exterior, accessible to firefighters.
- Allows fire departments to gain immediate access during emergencies, reducing the need for forcible entry.
- Vaults within a city are keyed alike, simplifying access for fire personnel.
Forcible Entry Challenges
- Strategies for forcible entry must adapt to evolving security measures.
- Firefighters should regularly assess local locks and barriers to develop effective breaching techniques.
- If the lock cylinder can be removed intact, it allows for key duplication.
- Locks engaging more than one inch into the jamb or that operate at multiple points present significant challenges, often requiring specialized tools.
