4.2 Fire Response Protocols: RACE, PASS and Building Systems

4.2 Fire Response Protocols: RACE, PASS and Building Systems

When a fire alarm sounds or smoke is detected inside an occupied facility, the response of the on-duty security guard must be swift, methodical, and disciplined. In structural fires, seconds often dictate whether an incident remains a minor, localized incipient event or escalates into a catastrophic multi-floor conflagration. A security officer cannot afford hesitation, panic, or guesswork. Through standardized tactical frameworks such as RACE and PASS, and through a comprehensive operational understanding of building fire safety systems—including Fire Alarm Control Panels, fire doors, sprinkler arrays, and manual call points—licensed security personnel protect human life, preserve building structural integrity, and ensure smooth coordination with responding UAE Civil Defence units.

Structural Fire Action Protocol: RACE

The globally recognized standard for structural fire response in commercial facilities, healthcare centers, and educational institutions is the RACE protocol. This four-step operational sequence establishes clear priorities, ensuring that life safety actions always precede property salvage or fire containment.

┌─────────────────────────────────────────────────────────────────────────────┐
│                         THE RACE OPERATIONAL PROTOCOL                       │
├─────────────────────────────────────────────────────────────────────────────┤
│  R ──► RESCUE     Remove anyone in immediate danger without risking self    │
│  A ──► ALARM      Activate manual call point & call Civil Defence (997)     │
│  C ──► CONTAIN    Close all doors and windows to isolate smoke and flames   │
│  E ──► EXTINGUISH Extinguish incipient fire IF safe, otherwise EVACUATE     │
└─────────────────────────────────────────────────────────────────────────────┘

1. R — Rescue (or Remove)

• Operational Action: Immediately remove or assist any persons in immediate, life-threatening danger from the burning room or compartment.
• Absolute Rule: The security officer must never place their own life in unreasonable peril. A security guard who becomes trapped or incapacitated cannot assist others and creates a second critical rescue burden for arriving firefighters. If a room is engulfed in dense black smoke or intense heat, do not enter; focus on clearing adjacent corridors.

2. A — Alarm (or Alert)

• Operational Action: Sound the building fire alarm immediately to alert all occupants and summon emergency services.
• Manual Call Point (MCP): Strike or press the nearest red break-glass manual call point located along the exit route.
• Emergency Dispatch Notification: Contact UAE Civil Defence via the national emergency dispatch number: 997.
• Dispatch Information Checklist: When speaking to the Civil Defence operator, remain calm and convey the 5 Critical Dispatch Points:
  1. Exact facility name, emirate, community/district, street name, and building plot number.
  2. Precise location of the fire within the property (e.g., Tower B, 7th floor, electrical riser room 704).
  3. Nature and magnitude of the fire (e.g., heavy electrical smoke, burning furniture, visible flames).
  4. Known casualties, trapped persons, or Persons of Determination requiring rescue.
  5. Designated rendezvous gate or entry point where a security guard will meet and guide arriving fire engines.
• Internal Escalation: Notify the building Security Operations Center (SOC) or control room and building facility management via two-way radio.

3. C — Contain (or Confine)

• Operational Action: Confine the fire, smoke, and superheated toxic gases to the room or compartment of origin by closing all doors and windows.
• Scientific Principle: Closing doors starves the fire of fresh incoming oxygen, slows the fire's heat release rate, and prevents lethal smoke from migrating into protected escape corridors and vertical stairwells. Never lock exit doors; simply ensure they are fully latched shut.

4. E — Extinguish (or Evacuate)

• Operational Action: Evaluate whether to combat the fire or initiate immediate total evacuation.
• Conditions for Extinguishment: A security guard should attempt to extinguish the fire only if all five conditions are satisfied:
  1. The fire is small and in its incipient stage (no larger than a standard office wastepaper bin).
  2. The correct type and size of portable extinguisher is immediately at hand.
  3. The guard has been trained and feels confident in operating the equipment.
  4. The atmosphere is free from dense toxic smoke, poisonous fumes, or excessive heat.
  5. The guard has a clear, unblocked, unobstructed emergency escape exit at their back.
• Evacuation Mandate: If the fire spreads beyond its initial container, if flames begin rolling across the ceiling (flashover indicator), or if one full extinguisher fails to quench the blaze, cease firefighting efforts immediately. Abandon the compartment, close the door behind you, and proceed with full building evacuation.

Operating Portable Extinguishers: The PASS Technique

When the decision to fight an incipient fire is made, the security officer must execute the standardized PASS technique. This mnemonic ensures correct, safe, and effective extinguisher discharge under stress.

       [ P ] ──► PULL the safety pin (breaks the plastic tamper seal)
       [ A ] ──► AIM low at the base of the fire (where fuel burns)
       [ S ] ──► SQUEEZE the discharge lever steadily
       [ S ] ──► SWEEP from side to side across the fuel bed

Step-by-Step Breakdown of PASS:

1. P — Pull the Pin: Grasp the ring pin firmly and pull it straight out, breaking the plastic inspection tamper seal. Do not squeeze the operating levers while pulling the pin; squeezing compresses the locking mechanism and prevents the pin from releasing.
2. A — Aim Low at the Base: Aim the nozzle, hose, or horn directly at the base of the flames—the actual burning material or liquid surface. Aiming into the rising flames or smoke is completely ineffective because the extinguishing agent will pass through the heat column without cooling or blanketing the fuel bed.
3. S — Squeeze the Lever: Squeeze the top operating lever down toward the carrying handle. This depresses the internal valve plunger, releasing pressurized gas that forces the extinguishing agent up the siphon tube and out through the discharge hose.
4. S — Sweep from Side to Side: Sweep the nozzle back and forth in a smooth, rhythmic motion across the entire breadth of the burning fuel bed. Advance slowly as the fire is knocked down, maintaining continuous visual control over the burning surface.

Critical Tactical Rules of Engagement:

• Maintain Standoff Distance: Initiate discharge from a safe standoff distance of 6 to 8 feet (2 to 2.5 meters). Discharging too close to a liquid fire can blast burning fuel out of its container, splashing onto surrounding walls and the operator.
• Unobstructed Rear Escape Route: Always position yourself with an unobstructed emergency exit or corridor directly behind you. Never allow the fire to position itself between you and your exit.
• Never Turn Your Back on a Fire: Even after flames appear completely dead, back away slowly while keeping your eyes fixed on the burn site. Smoldering embers or hot vapor pockets can flash back into active flames in an instant.

Active and Passive Building Fire Systems

Modern commercial and residential infrastructure across Abu Dhabi is engineered with sophisticated fire protection systems. Security guards must thoroughly understand how these systems operate to monitor them effectively and assist emergency services.

└──────────────────────────────┴──────────────────────────────────────────────┘

1. Manual Call Points (MCPs / Break-Glass Units)

Manual call points are red, wall-mounted rectangular boxes installed along all primary egress routes, next to corridor fire exit doors, and at stairwell landings. When an occupant or guard discovers a fire, pressing the flexible plastic element or breaking the glass panel immediately activates the facility's master fire alarm sounders and transmits a fire signal to the central monitoring station.

2. Automatic Fire Detection Devices

• Optical (Photoelectric) Smoke Detectors: Utilize an internal light beam and light sensor. When smoke enters the chamber, particles scatter the beam onto the sensor, tripping the alarm. Highly effective for smoldering, smoky fires (burning upholstery, plastics, documents).
• Ionization Smoke Detectors: Utilize a minute radioactive source to ionize air molecules. Fast-flaming fires produce tiny combustion particles that disrupt the ion current, triggering an instant alarm.
• Heat Detectors: Installed in environments where smoke, dust, or steam would cause frequent false alarms (kitchens, loading bays, boiler rooms, underground parking garages). They operate on two principles: Fixed Temperature (tripping when heat reaches a preset threshold, e.g., 58°C or 78°C) or Rate-of-Rise (tripping when temperature climbs rapidly, e.g., exceeding 8°C per minute).

3. The Fire Alarm Control Panel (FACP)

The FACP serves as the central operational brain of a building's fire safety network, typically located in the ground-floor security control room or main reception.

┌─────────────────────────────────────────────────────────────────────────────┐
│                     THE FOUR PRIMARY FACP STATUS STATES                     │
├─────────────┬───────────────────────────────────────────────────────────────┤
│ Normal      │ Steady green 'Power On' LED; system fully operational.        │
│ Fire Alarm  │ Flashing red LED, pulsing audio buzzer, displays zone/room ID.│
│ Supervisory │ Yellow/amber LED; indicates valve tamper or pump system fault.│
│ Trouble     │ Yellow/amber LED; indicates circuit fault, battery cut, dust. │
└─────────────┴───────────────────────────────────────────────────────────────┘

Strict FACP Operational Rules for Security Personnel:

1. The Investigation Mandate: When a fire alarm trips, the control room guard must immediately note the exact zone, floor, and device address displayed on the LCD screen, then dispatch the roving patrol guard to physically investigate the location.
2. The Golden Silence/Reset Rule: NEVER SILENCE OR RESET THE FACP BEFORE THE CAUSE OF THE ALARM HAS BEEN PHYSICALLY VERIFIED. Silencing the alarm silences building evacuation sounders while an actual fire may be suffocating occupants on upper floors. Resetting the panel erases critical diagnostic data and unlocks safety systems prematurely. Only the UAE Civil Defence Incident Commander or the authorized security supervisor may authorize a system reset after the scene is declared safe.

4. Fire Doors and Compartmentation

Fire compartmentation divides a building into self-contained fire-resistant "cells" using concrete slab floors, reinforced masonry walls, and certified fire doors. Compartmentation restricts fire, heat, and smoke to its origin room for a certified rating period (typically FD30 = 30 minutes, FD60 = 60 minutes, or FD120 = 120 minutes).

• Intumescent Perimeter Seals: Embedded along the edge of every fire door is an intumescent strip (often graphite-based). When heated in a fire, these strips swell to many times their original thickness, creating an impenetrable, airtight seal that stops deadly smoke and toxic fumes from leaking around the door perimeter.
• The Propping / Wedging Violation: Under UAE Civil Defence regulations, propping or wedging fire doors open using wooden wedges, fire extinguishers, or chairs is a severe, fineable safety violation. A wedged fire door completely invalidates building compartmentation, transforming escape stairwells into superheated chimneys filled with toxic smoke.

5. Fire Hose Reels

Fire hose reels consist of 30 meters of semi-rigid, non-kinking 25mm rubber hose connected directly to the building's pressurized wet-riser water main. Located in recessed wall cabinets along corridors, they deliver a continuous water jet or fog spray. Hose reels are strictly designed for Class A solid fires. They must never be directed onto electrical switchgear, energized server cabinets, or burning oil vats.

6. Automatic Fire Sprinkler Systems

Fire sprinkler arrays protect commercial buildings through pressurized overhead pipe networks fitted with heat-sensitive sprinkler heads.

• Thermal Glass Bulb Mechanism: Each sprinkler head is held closed by a small glass bulb filled with a glycerin-based liquid and an air bubble. When heat from a fire rises to a specific temperature, the liquid expands, shattering the glass bulb and allowing pressurized water to strike the deflector plate, showering the fire below.
• Standard Temperature Rating: In commercial and residential buildings, standard sprinkler bulbs are colour-coded Red, designed to shatter at 68°C (155°F).
• Debunking the Hollywood Myth: Sprinkler heads activate individually, not simultaneously across the entire floor. Only the specific heads directly exposed to heat shatter and discharge water.
• The Clearance Rule: Storage must never reach up to the sprinkler heads. The sprinkler chapter of the UAE Fire and Life Safety Code sets a minimum clearance between the top of storage and the sprinkler head: 500 mm in the published Code, and 1,000 mm for special sprinklers such as ESFR. The international benchmark in NFPA 13 is 18 inches (457 mm). Stacking stock, archive boxes or partitions too close to the heads blocks the spray pattern, so water cannot reach the base of a fire. Report it immediately.

Smoke Inhalation Hazards and Tactical Survival

Fire safety agencies consistently report that most fire deaths are caused by smoke inhalation and toxic gases rather than by burns. In a burning room, smoke incapacitates occupants long before flames reach them.

The Lethal Chemistry of Fire Smoke

Fire smoke is not merely irritating soot; it is a complex, superheated cocktail of unburned carbon particles, toxic chemicals, and suffocating gases:

• Carbon Monoxide (CO): An odorless, colorless, tasteless gas generated by incomplete combustion. CO binds to blood hemoglobin with an affinity 200 to 250 times greater than oxygen, forming carboxyhemoglobin. This prevents the blood from carrying oxygen to the brain and vital organs, causing disorientation, headache, loss of consciousness, and death within minutes.
• Hydrogen Cyanide (HCN): Released when modern synthetic materials, polyurethane foam cushions, carpets, and nylon fabrics burn. HCN is an extraordinarily fast-acting cellular toxin that halts cellular respiration. It is far more toxic than CO and can cause collapse after only a few breaths.

Thermal Layering and the "Stay Low" Rule

As fire burns, heated gases become buoyant and rise toward the ceiling, creating distinct stratified thermal layers. The hottest, most lethal, and most oxygen-depleted gases collect at the ceiling, while cooler, cleaner air with higher oxygen concentrations remains near the floor.

Ceiling  ┌────────────────────────────────────────────────────────┐
         │  SUPERHEATED TOXIC SMOKE LAYER (>300°C, CO, HCN, Soot) │
         ├────────────────────────────────────────────────────────┤
         │  THERMAL INTERFACE / SMOKE BOUNDARY                    │
         ├────────────────────────────────────────────────────────┤
         │  CLEANER, COOLER AIR ZONE (Higher O2, Lower Heat)     │
Floor    └────────────────────────────────────────────────────────┘
                      ◄── CRAWL LOW (30cm to 60cm) ──►

Tactical Survival Guidelines:

• Crawl Low: If trapped in a smoke-filled corridor, drop to your hands and knees. Keep your head within the clean air zone, 30 to 60 centimeters (1 to 2 feet) above the floor. Cover your mouth and nose with a damp cloth if available to filter out coarse soot particles (note: cloth does not filter out toxic CO or HCN gases).
• Follow Walls: In zero-visibility smoke, crawl along the perimeter wall using the back of your hand to feel the baseboard. This prevents disorientation and guarantees you will encounter an exit door rather than walking in circles.

Tactile Door Checking: The Back-of-the-Hand Technique

Before opening any closed door during a fire emergency or building sweep, a security guard must test the door for internal fire conditions. Opening a hot door introduces fresh oxygen to a smoldering, oxygen-starved compartment, which can instantly trigger a violent, explosive backdraft that incinerates the officer.

[TACTILE DOOR CHECK PROTOCOL]
1. Crouch low beside door frame (out of direct blast path)
2. Place BACK OF HAND lightly near bottom of door
3. Slide BACK OF HAND up to center and door frame
4. Touch metal door handle with BACK OF HAND
       │
       ├─► IF HOT: DO NOT OPEN! Seal bottom crack with cloth. Evacuate.
       │
       └─► IF COOL: Open cautiously, bracing shoulder against door.

Why Use the Back of the Hand?

1. Skin Sensitivity: The skin on the back of the human hand is significantly thinner and more sensitive to subtle thermal changes than the calloused palm.
2. Involuntary Muscle Spasm Prevention: If a guard grabs a superheated metal door handle with an open palm, the intense thermal shock triggers the physiological flexor reflex, causing the hand muscles to clench shut involuntarily around the burning metal, causing catastrophic third-degree burns and trapping the guard against the door. Testing with the back of the hand ensures that any sudden reflex pulls the hand safely away from the danger.

             Tariq Notifies Civil Defence (997) & Updates Incident Log

Applied Actions and Decision-Making

1. FACP Discipline: Tariq does not press "Silence" or "Reset." He notes the exact device location, dispatches mobile patrol Officer Rashid via two-way radio, and places UAE Civil Defence dispatch (997) on standby.
2. Tactile Testing: Arriving at the B2 waste room, Rashid observes light wisps of smoke seeping through the top seam. He crouches low and checks the door with the back of his bare hand from bottom to handle. The handle is cool.
3. Safe Entry & Extinguishment: Rashid retrieves a 6-kg ABC dry powder extinguisher from the corridor bracket. Standing behind the protective shelter of the masonry doorframe, he opens the door slightly. Seeing a small pile of smoldering packaging boxes (incipient fire, no structural involvement), Rashid maintains an unblocked escape path at his back, stands 2.5 meters away, pulls the pin, aims at the base of the cardboard, squeezes the handle, and sweeps the nozzle. The fire is completely extinguished in 8 seconds.
4. Post-Incident Containment: Rashid backs out slowly, maintaining eye contact with the smoldering pile, closes and latches the fire door to prevent smoke migration into the parking garage, and radios Tariq. Arriving Civil Defence personnel conduct thermal imaging to confirm total extinguishment before authorizing the FACP system reset.

Section Summary Review Checklist for the PSBD Exam

• RACE Protocol: Rescue persons in danger -> Alarm (call Civil Defence at 997 & hit MCP) -> Contain (close doors) -> Extinguish incipient fires or Evacuate.
• PASS Technique: Pull pin -> Aim low at base of fire -> Squeeze lever -> Sweep side to side. Maintain 2.0 to 2.5 m standoff; keep exit at rear; never turn back.
• FACP Operations: 4 states: Normal (green), Alarm (flashing red), Supervisory (yellow), Trouble (yellow). NEVER silence or reset without physical verification and authorization.
• Fire Doors & Compartmentation: FD30/FD60/FD120 ratings with intumescent seals that swell under heat. Never prop, wedge, or obstruct fire doors.
• Sprinkler Systems: Red bulb shatters at 68°C. Heads activate individually. Keep storage well below the heads; the UAE Code sets a clearance of at least 500 mm between the top of storage and sprinkler heads.
• Smoke Survival: Smoke and toxic gases (CO, HCN) cause most fire deaths. Crawl low within 30-60 cm clean air layer. Test doors with back of hand, never the palm.
