4.1 Fire Safety, Response & Evacuation Protocols

Key Takeaways

  • The Fire Tetrahedron consists of four essential elements required for fire: Oxygen, Heat, Fuel, and an Uninhibited Chemical Chain Reaction; removing any single element extinguishes the fire.
  • Fire classifications govern extinguisher selection: Class A (ordinary combustibles), Class B (flammable liquids/gases), Class C (energized electrical), Class D (combustible metals), and Class K (commercial cooking media).
  • The PASS method dictates portable fire extinguisher operation: Pull the safety pin, Aim low at the base of the fire, Squeeze the lever, and Sweep side-to-side from a safe distance of 6 to 8 feet.
  • The RACE emergency protocol establishes life-safety response order: Rescue individuals in direct danger, Alarm by pulling stations and calling 911/FDNY, Contain fire by closing doors, and Extinguish incipient fires or Evacuate immediately.
  • Post-evacuation responsibilities require security guards to guide occupants via stairwells, keep egress routes clear, maintain assembly point headcounts, and meet arriving FDNY units with master keys and elevator controls.

4.1 Fire Safety, Response & Evacuation Protocols

NY Security Guard Standard: Security officers in New York State serve as the initial line of defense against structural fire hazards. Officers must maintain constant vigilance, understand fire chemistry, execute early detection and containment procedures, and direct safe facility evacuations in coordination with the Fire Department of the City of New York (FDNY) or local municipal fire departments.

Fire emergencies in commercial office buildings, retail centers, residential complexes, and industrial sites present immediate life-safety hazards. Security officers are responsible for fire prevention inspections, monitoring fire alarm control panels (FACP), initiating life-safety responses, operating portable fire extinguishers, and managing building evacuations.


The Fire Tetrahedron

To effectively prevent and suppress fires, security officers must understand the chemical process of combustion. Fire is represented scientifically by the Fire Tetrahedron, a four-sided geometric model illustrating the four components required for a fire to exist and sustain itself:

  1. Fuel: Combustible matter in solid, liquid, or gaseous form (e.g., paper, wood, gasoline, natural gas) that oxidizes during combustion.
  2. Oxygen: An oxidizing agent, typically provided by ambient atmospheric air (which contains approximately 21% oxygen). Most fires require at least 16% oxygen to sustain combustion.
  3. Heat: Thermal energy required to raise the fuel temperature to its specific ignition point or auto-ignition temperature.
  4. Uninhibited Chemical Chain Reaction: The continuous self-sustaining molecular reaction between fuel, oxygen, and heat that produces light, heat, flame, and toxic combustion byproducts (carbon monoxide, hydrogen cyanide, smoke particulate).
          [ HEAT ]
          /  |   \
         /   |    \
   [ FUEL ]--+--[ OXYGEN ]
         \   |    /
          \  |   /
   [ CHEMICAL CHAIN REACTION ]

Principle of Fire Suppression: Fire extinguishing agents work by removing or interrupting at least one of these four legs. For example, water cools the heat element, carbon dioxide or foam smothers the oxygen element, shutoff valves isolate the fuel source, and halocarbon/dry chemical agents chemically interrupt the molecular chain reaction.


Fire Classifications & Extinguisher Selection

Fires are categorized into five distinct classes based on the composition of the fuel involved. Using the incorrect fire extinguisher type can prove ineffective or catastrophically dangerous (for example, applying water to an electrical or grease fire).

Fire ClassSymbol / PictogramFuel Sources & MaterialsRecommended Extinguishing AgentDangerous / Prohibited Agents
Class AGreen Triangle / Trash Can & WoodOrdinary combustibles: wood, paper, cloth, rubber, cardboard, many plasticsWater (APW), Multipurpose ABC Dry Chemical, Water MistCO2 (less effective on deep-seated solid embers)
Class BRed Square / Fuel CanFlammable & combustible liquids/gases: gasoline, diesel, oil, paint, solvents, propaneCarbon Dioxide (CO2), ABC/BC Dry Chemical, Foam (AFFF)WATER (causes flammable liquid to splatter and spread fire rapidly)
Class CBlue Circle / Electric PlugEnergized electrical equipment: circuit breakers, wiring, appliances, transformers, computersCarbon Dioxide (CO2), ABC/BC Dry Chemical, Clean Agents (Halotron)WATER or Conductive Liquid (causes severe electrical shock/electrocution)
Class DYellow Star / Metal GearCombustible metals: magnesium, titanium, zirconium, sodium, potassium, lithiumClass D Specialized Dry Powder (e.g., Sodium Chloride / Copper powder)WATER or Standard Extinguishers (causes violent explosions/chemical reactions)
Class KBlack Hexagon / Frying PanCommercial cooking media: vegetable oils, animal fats, canola oil in commercial deep fryersClass K Wet Chemical (Potassium Acetate / Potassium Citrate solution)WATER (causes steam explosion throwing boiling oil across kitchen)

Operating Technique: The P.A.S.S. Method

Security officers should only attempt to extinguish fires that are in their incipient stage (small, contained fires no larger than a standard trash container) and only when an unblocked exit path is maintained behind the officer. When operating a portable fire extinguisher, follow the standard P.A.S.S. technique:

  • P — Pull the Pin: Pull the safety pin located at the top of the extinguisher handle. Breaking the plastic tamper seal ring unlocks the operating lever.
  • A — Aim Low at the Base: Point the extinguisher nozzle, hose, or horn low, aiming directly at the base of the fire where the fuel source is located, rather than at the rising flames.
  • S — Squeeze the Lever: Squeeze the upper operating lever or handle down firmly to discharge the extinguishing agent. Releasing the lever stops the agent discharge.
  • S — Sweep Side-to-Side: Sweep the nozzle from side to side across the base of the fuel source, advancing carefully as the fire is knocked down. Maintain a safe standoff distance of 6 to 8 feet throughout operation.

Emergency Life Safety Response: The R.A.C.E. Protocol

During any structure fire or active fire alarm activation, security officers must follow the established R.A.C.E. emergency protocol to prioritize occupant safety and facility containment:

  1. R — Rescue (Remove): Immediately rescue and evacuate any occupants who are in direct, imminent physical danger, provided doing so does not compromise officer safety.
  2. A — Alarm: Immediately activate the building fire alarm system by pulling the nearest manual fire alarm pull station. Contact 911 / FDNY dispatch immediately. State the exact building address, floor level, suite number, nature of fire/smoke, and your officer identification.
  3. C — Contain: Isolate and contain the fire and smoke by closing all interior doors, fire barrier doors, and windows behind you as rooms are evacuated. Closing doors starves the fire of oxygen draft and prevents toxic smoke from filling corridors and stairwells.
  4. E — Extinguish or Evacuate: If the fire is small (incipient) and you have appropriate training and equipment, attempt to Extinguish using the PASS method. If the fire spreads rapidly, generates heavy dark smoke, or threatens your exit path, Evacuate immediately via primary emergency stairwells.

Building Evacuation Management & FDNY Coordination

During a building evacuation, security guards transition into critical crowd control and evacuation managers:

Egress Route Inspections & Fire Prevention Patrols

  • Stairwells & Doors: Conduct daily patrols to ensure stairwells, exit corridors, and emergency exit doors are completely clear of pallets, boxes, or debris. Fire doors must never be propped open with wedges or blocks.
  • Illuminated EXIT Signs & Emergency Lighting: Verify that illuminated EXIT signs are lit and that battery-backup emergency lighting units operate properly during monthly tests.
  • Fire Command Center (FCC): Familiarize yourself with the building's Fire Alarm Control Panel (FACP), smoke purge systems, public address (PA) voice communication systems, and fire pump status panels.

Executing Evacuations & Assembly Accounting

  • Directing Occupants: Guide building occupants calmly toward primary and secondary fire stairwells. Remind occupants NEVER to use passenger or freight elevators during a fire evacuation (elevators can become trapped due to heat, power loss, or shaft smoke accumulation).
  • Assisting Persons with Disabilities: Direct mobility-impaired occupants to designated Areas of Rescue Assistance (Areas of Refuge) within reinforced stairwell landings equipped with two-way emergency call boxes.
  • Post-Evacuation Roll Call: Direct all evacuees to designated outdoor assembly points (located a safe distance upwind from the building). Coordinate with floor wardens to conduct headcount roll calls.
  • FDNY Liaison: Position an officer at the main entrance or Fire Command Center to meet arriving FDNY units. Provide firefighters with master key cards (or Knox Box access), elevator service keys (Phase I / Phase II control), building floor plans, hazardous material locations, and reports of any trapped or missing occupants.
