Study Notes
Forcible Entry Key Concepts
- Forcible entry refers to entering a structure using force against resistance or opposition.
- Firefighter safety is a crucial aspect of forcible entry, ensuring the ability to exit safely.
- Effective size-up for forcible entry starts long before an emergency occurs.
Factors Influencing Success
- Success in forcible entry operations relies on the collective result of judgment, experience, and available equipment.
- Knowledge about construction methods and security helps determine the most suitable point of entry, typically the weakest point.
Size-Up Considerations
- Important considerations include the size and number of required openings and exit points.
- Factory, hinged, or casement windows are best opened by breaking the lowest pane of glass to unlock the mechanism.
Types of Windows
- Jalousie windows, comprised of small glass sections, are the most challenging type to force open.
Tools for Barricade Removal
- Power saws, especially those with carbide teeth, can efficiently remove barricades with minimal effort.
- The presence of four carriage bolt heads indicates a barricade utilizing two two-by-fours for reinforcement, commonly known as a HUD window.
Techniques and Strategies
- For horizontal bars, using a pickhead or flathead axe is effective. Strike top first and bottom last to drive out lag bolts efficiently.
- A rotary saw or sledge can also be employed to remove security bars in wall structures.
Lock Mechanisms
- A common residential lock, the key-and-knob lockset, features a keyway in the doorknob.
- The mortise lock is one of the oldest types, recognized by its installation within a cavity in the door's edge.
Types of Bolts and Cutting Techniques
- A deadbolt and doorknob latch bolt often work together where two turns of the key activate each type of bolt.
- A rotary saw can effectively cut bolts positioned at the bottom of the door.
Tool Usage
- When using a rotary saw for forcible entry, it should be carried with the blade in the outboard position.
- Common exit hardware may require unique tools fashioned from materials like a car antenna or metal coat hangers due to accessibility constraints.
Door Types and Cutting Techniques
- Overhead doors are prevalent in commercial buildings for covering openings like loading docks and garages.
- A common forcible entry technique involves making a triangle, tee-pee, or inverted V cut in the door.
Door Categories and Limitations
- Sectional doors are classified as either ordinary or wind-resistant.
- A rotary saw with a new 14-inch composite blade can cut to a maximum depth of 5 1/2 inches.
Breaching Operations
- Breaching walls to create openings is typically a last resort, as it requires notable time and effort.
