Introduction

Firefighters often need to access buildings through doors, windows, or walls. When doors are locked, forcible entry becomes essential. Over time, forcible entry has been a crucial aspect of firefighting. The tools and techniques used for this purpose have evolved significantly, thanks to technological advancements and innovative designs, leading to lighter and more versatile tools.

Executing forcible entry requires a variety of tools and techniques, ranging from basic to advanced. Understanding these methods allows firefighters to perform effectively in scenarios such as search and rescue, fire suppression, or ventilation. Entry must precede any tactical operations. Importantly, accessing a structure is key to carrying out firefighting and rescue efforts safely and efficiently.

Typically, operations begin at the main entrance of a building. Considering what lies beyond the door and minimizing damage during tactical operations are vital. With proper training, firefighters can open doors with minimal damage and disruption.

Professionalism in Forcible Entry

Professionalism is a hallmark of an excellent firefighter. Representing the fire department and, ultimately, the community, firefighters’ pride in their work reflects in their actions. Minimizing damage to property ensures the safety and trust of the people they serve.

Breaking down doors during a fire response can lead to additional risks for residents. Firefighters must make sound decisions, considering the aftermath of their actions. Efficient and safe execution, with minimal destruction, is a core responsibility.

Situational awareness is key. In some cases, entering through a window or using non-destructive techniques may be more appropriate. Always use common sense, and account for the risks both during and after the operation.

Situational Assessment (Size-Up)

Size-up involves gathering information, observing the situation, and predicting outcomes, forming the foundation for strategic decisions. Key considerations include:

• Fire Location: Where is the fire situated?
• Building Layout: How many floors does the building have?
• Building Type: What kind of structure is it?

Size-up begins upon arrival and continues until the fire is fully extinguished. Knowing the building’s structure and the types of doors and locks helps determine the appropriate tools and methods for entry.

Factors to Consider Before Forcible Entry

When attempting entry, assess the following conditions:

• Urgency of Entry: How critical is immediate access?
• Relation to Emergency: Is the point of entry optimal for the emergency?
• Conventional Methods: Can the door be opened without force?
• Damage Minimization: What approach causes the least damage?
• Speed of Access: Which method is the quickest?
• Ventilation Needs: Is ventilation necessary before entry?
• Hose Line Preparation: Should hoses be set up before entry?

For Non-Emergency Situations:

• Contact emergency services, security personnel, or building staff for access.
• Check for unlocked doors or windows before forcing entry.
• Evaluate accessible windows or doors based on repair costs and convenience.

For Fire or Smoke Presence

When smoke or fire is present, verify the following:

• Select an entry point based on fire conditions.
• Check for signs of backdraft before entry.
• Test all doors and windows for accessibility.
• Evaluate glass openings for potential access to locks.
• Use tools to force the door if no alternative exists.

Key Components of a Door

Overview of a Door

• A door significantly affects the appearance and functionality of a house.
• Understanding the names and roles of each part helps you communicate better with contractors and dealers.

Door Frame

• Definition: The structural horizontal and vertical components that hold the door in place, installed in a wall opening.
• Materials: Typically wood, but aluminum, fiberglass, and composite materials are also popular.
• Main Components:
  • Head (Header): The horizontal piece at the top of the frame.
  • Jambs: The vertical pieces on both sides of the frame, supporting the door like “legs.”
  • Sill: The horizontal piece at the bottom, fixed to the floor to block insects, dust, and water.
  • Casing: A decorative covering that hides gaps between the frame and wall.

Related Parts of the Door Frame

• Threshold: A transition piece between the sill and the floor, often decorative and durable.
• Stop Moulding: A trim that keeps the door panel in place and prevents it from swinging freely.
• Door Trim: A decorative element that covers gaps between the frame and wall.
• Sidelights: Narrow windows on either side of a door, adding light and aesthetic appeal.
• Transom: A decorative feature or window above a door.
• Brick Mould: An exterior trim covering gaps between the frame and the wall.

Door Panel Parts

• Panel: The main moving part of the door, covering the central area.
• Stile: The vertical edges of the door panel. One side is for the lock (lock stile), and the other is for the hinges (hinge stile).
• Rails: The horizontal pieces on the door panel, located at the top, bottom, and middle.
• Mullion/Muntin: Vertical pieces dividing panels or glass sections on the door.
• Astragal: A strip that fills gaps between double doors for sealing and decoration.

Other Related Components

• Weather-stripping: Rubber or silicone strips that seal gaps between the door and frame to prevent drafts.
• Door Sweep: A weatherproof strip attached to the bottom of the door panel to block air, dust, or water.
• Rough Opening: The opening in the wall where the door frame is installed, adjusted with shims for a secure fit.

Types of Doors and Materials

Wooden Doors

• Hollow Core: Used indoors, lightweight, and grid-structured.
• Solid Core: Filled with solid wood or compressed materials for durability.

Metal Doors

• Often found in fire-resistant frames, offering robust protection against fire spread.

Glass Doors

• Increasingly popular in commercial spaces. Must use tempered glass, which is heat-treated for strength and safety.

Types of Locks

Cylinder Locks

Recessed locks commonly seen in modern buildings. They often have a combination of deadbolts and latch bolts.

Integral Locks

Used in older structures, integrating the cylinder into the knob.

Thumb Latch Locks

Operated by pressing a lever, often seen in residential homes.

Push-Pull Locks

Modern, stylish locks used in residential and commercial settings, allowing easy push or pull to open.

Sliding Door Locks

Used for sliding doors, featuring a hook-like bolt mechanism.

Electronic Locks

Common in apartments and large complexes, these locks operate via an electrical switch.

Conclusion

Understanding the fundamentals of doors, locks, and forcible entry techniques is essential for safe and efficient firefighting. By minimizing property damage and ensuring timely access, firefighters can protect both lives and assets while maintaining professionalism.

Proper training, situational awareness, and informed decision-making form the cornerstone of successful forcible entry operations.
