INTRODUCTION • Modern society is security conscious • Private homes • Commercial occupancies • Vehicles • Forcible entry • The technique used by fire department personnel to gain access to a structure whose normal means of access is locked, blocked or nonexistent
INTRODUCTION • Forcible entry, when properly used, does a minimal amount of damage to the structure or structural components and provides quick access for firefighters • should not be used when normal means of access are readily available • may be required to open means of egress (exit) from structures
INTRODUCTION • Knowing the construction features of doors, windows and other barriers, knowing proper tool selection and knowing forcible entry techniques greatly enhances a firefighter’s effort on the fireground • Ability to use forcible entry techniques quickly and effectively demonstrates professionalism to the community you serve
FORCIBLE ENTRY TOOLS • A firefighter must have a complete working knowledge of the tools available to perform the task • Using the proper tool will make the difference in whether the barrier faced is successfully forced • Forcible entry tools can be divided into four basic categories • Cutting tools • Prying tools • Pushing / pulling tools • Striking tools
FORCIBLE ENTRY TOOLS • Cutting Tools • Many different types • Often specific to the type of materials they can cut and how fast they can cut them • No such thing as a single cutting tool that will efficiently cut all materials • Using a cutting tool in a way it was not designed can destroy the tool and endanger the operator • Cutting tools may be either manual or powered
CUTTING TOOLS • Axes and Hatchets • The most common type of cutting tool available in the fire service • Two basic types • Pick-head • Flat-head • Pick-head axe • 6 pound or 8 pound head • Handle made of either wood or fiberglass • Effective for cutting through natural and lightweight materials
CUTTING TOOLS • Axes and Hatchets • Flat-head axe • 6 or 8 pound head • Handles made of either wood or fiberglass • Cuts through a variety of natural and lightweight materials • Can be used as a striking tool
CUTTING TOOLS • Handsaws • There are times when the handsaw is necessary because of a small work space • Commonly used handsaws • Carpenter's handsaw • Keyhole saw • Hacksaws • Coping saw
CUTTING TOOLS • Power Saws • Make fast and efficient cuts in a variety of materials • Times when these saws should and should not be used • Divided into categories • Rotary (circular) saw • Reciprocating saw • Chain saw • Ventilation saw
CUTTING TOOLS • Power Saws • Do not push a saw (or any tool) beyond the limits of its design and purpose • Two things may occur • Tool failure • Injury to the operator • Never use a power saw in a flammable atmosphere • Always use eye protection when operating any power saw
CUTTING TOOLS • Power Saws • Rotary (Circular) Saw • Fire service version is often gasoline powered • Blades spin more than 6,000 rpm • Blades range from large-toothed blades for quick rough cuts to fine teeth for a more precise cut • Carbide tipped teeth are superior to standard blades • Less prone to dulling with heavy use
CUTTING TOOLS • Power Saws • Rotary (Circular) Saw • Blades specifically designed for cutting metal are also available • Often used in forcible entry • Following both manufacturer’s recommendations and department SOGs are imperative to maintaining a firefighter’s personal safety when operating saws
CUTTING TOOLS • Reciprocating Saw • Powerful, versatile and highly controllable saw • Can use a variety of blades for cutting different materials • Require electricity
CUTTING TOOLS • Chain Saw (Vent Saw) • Used for years by the logging industry • Sometimes more efficient than the rotary saw • Powerful enough to penetrate dense material yet lightweight enough to be easily handled in awkward positions • Should not be used to cut metal
CUTTING TOOLS • Metal Cutting Devices and Cutting Torches • Bolt cutters • Cuts bolts, iron bars, pins, cables, hasps, chains and some padlock shackles • Advances in security technology are limiting the use of bolt cutters • Materials shatter the cutting surface or cause the handles to fail
CUTTING TOOLS • Metal Cutting Devices and Cutting Torches • Cutting Torch • Operates by burning away the material being cut • Uses a mixture of flammable gases to generate a flame with a temperature of more than 5,700° F
PRYING TOOLS • Prying Tools • Provide an advantage for opening doors, windows, locks and moving heavy objects • Hand (manual) prying tools use the basic principle of the lever to provide a mechanical advantage • Leverage applied incorrectly works against the firefighter • Hydraulic prying tools can either be powered hydraulic or manual hydraulic • Manual hydraulic tools operate slower
PRYING TOOLS • Manual Prying Tools • Variety of hand prying tools is available to the fire service • Crowbar • Halligan-type bar • Hux bar • Claw tool • Kelly tool • Pry axe • Flat bar
PRYING TOOLS • Hydraulic Prying Tools • Hydraulic rescue spreader tool • Most often associated with vehicle extrication has some uses in forcible entry • Depending on manufacturer, spread as much as 32 inches
PRYING TOOLS • Hydraulic Prying Tools • Hydraulic ram • Designed primarily for vehicle extrication • Spreading capabilities ranging from 36 inches to an extended length of nearly 63 inches • Place the ram in between either side of a door frame to spread the frame apart
PRYING TOOLS • Hydraulic Prying Tools • Hydraulic door opener, is a hand-operated spreader device and is relatively lightweight • Consists of a hand pump and spreader device • Pressure usually causes the locking mechanism or door to fail • Valuable tool when more than one door must be forced • Apartments or hotels
PUSHING / PULLING TOOLS • Pushing / Pulling Tools • Limited use in forcible entry • Tool of choice for breaking glass and opening walls or ceilings • Tools includes • Standard pike pole • Clemens hook • Plaster hook • Drywall hook • San Francisco hook • Multipurpose hook • Roofman's hook
PUSHING / PULLING TOOLS • Pushing / Pulling Tools • Gives the firefighter additional reach • Stay out of the way of falling debris • Pike poles and hooks should not be depended on for leverage
STRIKING TOOLS • Striking Tools • Basic hand tool consisting of a weighted head attached to a handle • Sledgehammer (8, 10 and 16 pounds) • Maul • Flat-head axe • Sledge hammer • Multi-tool
TOOL COMBINATIONS • Tool Combinations • No single forcible entry tool provides the firefighter with the needed force or leverage to handle all forcible entry situations • The most important factor to consider is selecting the proper tools to do the job • Pre-incident surveys will help to determine what tools are required
TOOL SAFETY • Hand and power tools used in the fire service can be extremely dangerous if misused or used carelessly • In atmospheres that could be explosive, extreme caution should be taken in the use of power and hand tools that may cause arcs or sparks
TOOL SAFETY • Prying Tool Safety • Using prying tools incorrectly creates a safety hazard • Not acceptable to use a "cheater bar" • Can put forces on the tool that are greater than the tool was designed to handle
TOOL SAFETY • Circular Saw Safety • Must be used with extreme care to prevent injury from the high-speed rotary blade • Store blades in a clean, dry environment free of hydrocarbon fumes • Hydrocarbons will attack the bonding material in the blades and make them subject to sudden disintegration during use • Match the saw to the task and the material to be cut • Never push a saw beyond its design limitations • Wear proper protective equipment • Do not use any power saw when working in a flammable atmosphere or near flammable liquids
TOOL SAFETY • Circular Saw Safety • Keep unprotected and nonessential people out of the work area • Follow manufacturer's guidelines for proper saw operation • Keep blades and chain well sharpened • A dull saw is more likely to cause an accident than a sharp one • Be aware of potential hidden hazards
TOOL SAFETY • Carrying Tools • Carry tools and tool combinations in the safest manner possible • Axes • Carry the axe with the blade away from the body • Pick-head axes • Grasp the pick with a hand to cover it • Axes should never be carried on the shoulder
TOOL SAFETY • Carrying Tools • Prying Tools • Carry these tools with any pointed or sharp edges away from the body • Combinations of Tools • Strap tool combinations together • Halligan type bars and flat-head axes can be “married” together and strapped
TOOL SAFETY • Carrying Tools • Pike Poles and Hooks • Carry with the head down, close to the ground and ahead of the body • These tools can severely injure anyone poked with the working end of the tool
TOOL SAFETY • Carrying Tools • Striking Tools • Keep the heads of these tools close to the ground • Maintain a firm grip • Power Tools • Never carry a power tool that is running • Carry the tool to the area where the work will be performed and start it there
CARE AND MAINTENANCE • Care and Maintenance of Forcible Entry Tools • Proper care and maintenance of all forcible entry tools are essential ingredients of any forcible entry operation • Tools will function as designed if they are properly maintained and kept in the best of condition
CARE AND MAINTENANCE • Wood Handles • Inspect the handle for cracks, blisters or splinters • Sand the handle to minimize hand injuries • Wash the handle with mild detergent, rinse and wipe dry • Do not soak the handle in water because it will cause the wood to swell • Apply a coat of boiled linseed oil to the handle to prevent roughness and warping • Do not paint or varnish the handle • Check the tightness of the tool head • Limit tool marking
CARE AND MAINTENANCE • Fiberglass Handles • Wash the handle with mild detergent, rinse and wipe dry • Check the tightness of the tool head • Cutting Edges • Inspect the cutting edge for nicks, tears or metal spurs • Replace cutting edges when required • File the cutting edges by hand • Grinding weakens the tool
CARE AND MAINTENANCE • Plated Surfaces • Inspect for damage • Wipe plated surfaces clean or wash with mild detergent and water • Unprotected Metal Surfaces • Keep free of rust • Oil the metal surface lightly. avoid using any metal protectant that contains trichloroethane • Avoid painting • Inspect the metal for spurs, burrs or sharp edges and file them off when found
CARE AND MAINTENANCE • Axe Heads • The manner in which the axe head is maintained directly affects how well it works • If the blade is extremely sharp and its body is ground too thin pieces of the blade may break when cutting • If the body of the blade is too thick, regardless of its sharpness, it may be difficult to drive the axe head through ordinary objects
CARE AND MAINTENANCE • Power Equipment • Read and follow manufacturer’s instructions • Inspect and ensure power tools will start • Check blades for completeness and readiness • Replace blades that are worn • Check all electrical components for cuts and frays • Ensure that all guards are functional and in place • Ensure that fuel is fresh • Fuel mixtures may deteriorate over time
SIZE UP • Door Size-Up and Construction Features • Primary obstacle firefighters face in gaining access to a building is a locked or blocked door • Size-up of the door is an essential part of the forcible entry task • How the door functions • How it is constructed • How it is locked
SIZE UP • Door Size-Up and Construction Features • Doors function in one of the following ways • Swinging (either inward or outward) • Sliding • Revolving • Overhead
SIZE UP • Door Size-Up and Construction Features • Firefighters should try the door to make sure that it is locked before force is used • “try before you pry!” • If the door is locked, begin additional size-up • Which way does it swing? • Look for the door • In or out? • Does it slide left or right? • Does it roll up?
SIZE UP • Door Size-Up and Construction Features • Access doors to residences usually swing inward • Commercial, public assembly doors and industrial doors, swing outward • There will be times that even that best size-up and forcible entry effort will not be successful • Remember not to get focused on one effort and one technique • Spending too much time forcing a door is counterproductive • If the door proves too well secured, find another door
SIZE UP • Door Size-Up and Construction Features • After determining how a door functions, you must understand how the door is constructed • Doors range in construction types from interior hollow core to high-security steel • Most common door encountered is the wood swinging door, followed by the steel swinging door
SIZE UP • Wood Swinging Doors • Three general categories of wood swinging doors • Panel • Slab • Ledge • Entry doors on structures are usually panel or slab
SIZE UP • Wood Swinging Doors • The door is only one component of a door assembly • Doorjambs are the sides of the opening into which the door is fitted • Rabbeted jamb • A shoulder milled into the casing that the door closes against to form a seal • Stopped jamb • Has a piece of molding added to the door frame for the door to close on
SIZE UP • Panel Doors • wood panel doors are made of solid wood members insert with panels • panels may be wood or plastic • panel doors often have panels fitted into the door to allow in light • glass • Lexan (polycarbonate) • plastic • Plexiglas
SIZE UP • Slab Doors • a very common door • constructed in two ways • solid core • hollow core • many interior doors in residences are hollow core • core or center portion of door is made up of web or grid of glued wood strips over which several layers of plywood veneer panels have been glued
SIZE UP • Slab Doors (cont.) • most exterior slab doors found on newly constructed residences are hollow core • exterior slab doors on older homes may be solid core • not pierced by windows or other openings • panels on a slab door are purely decorative
