Emergency Response During Patrol: Medical, Fire, and Hazmat

Objective. Students will demonstrate the correct patrol officer first response to a medical emergency, a fire discovery, and a suspected hazardous material release, including scene safety actions, notification procedures, and patient hand-off to first responders.

As a patrol officer or security professional, you will almost certainly arrive at an emergency before paramedics, firefighters, or hazmat teams. Your job is not to replace those specialists—it is to protect life, stabilize the scene, notify the right people, and hand off safely. The three categories below share one overriding rule: secure yourself first. A responder who becomes a victim makes every emergency worse.

Medical Emergencies

When you encounter an unconscious, injured, or seriously ill person during patrol, the sequence matters.

Step 1 – Scene safety. Before touching anyone, scan for hazards: traffic, downed power lines, violent bystanders, or substances that could harm you. Don your gloves (standard PPE for all patient contact) and confirm the scene is safe to enter.

Step 2 – Radio dispatch first. Transmit your location, the nature of the emergency, and the number of patients before you begin hands-on care. Dispatchers start the EMS clock the moment they receive your call. A few seconds on the radio can mean minutes of faster paramedic response.

Step 3 – Begin care. Follow your CPR/first-aid certification protocols. Check responsiveness, open the airway, look for breathing, and begin CPR if indicated. Deploy the AED as soon as it is available—apply pads and follow audio prompts without interruption.

Step 4 – Patient hand-off. When EMS arrives, give a brief verbal report: patient age and sex, chief complaint, what you found, what you did, and any changes in condition. Step back immediately and let EMS take over. Document everything in your incident report.

Never remove your gloves until the patient is transferred and you have washed your hands. Bloodborne pathogen exposure is a real occupational hazard.

Fire Discovery

The RACE protocol is the standard framework used in most facilities and is recognized in security and healthcare environments alike.

R – Rescue / Remove anyone in immediate danger from the fire or smoke.
A – Alarm – Activate the nearest pull station or call 911 (do both if possible). Notify dispatch by radio with your location and what you see.
C – Contain – Close doors and windows without locking them to slow smoke and fire spread. Do not prop doors open.
E – Extinguish or Evacuate – Use a portable fire extinguisher only on a small, contained fire. If the fire is larger than a wastebasket, or if you have any doubt, evacuate immediately.

Using a fire extinguisher – PASS:

Pull the pin.
Aim the nozzle at the base of the fire.
Squeeze the handle.
Sweep side to side.

Always position yourself between the fire and the nearest exit so you can retreat. Never let a fire get between you and the door. Once the building is evacuating, guide occupants to the posted assembly point and account for all personnel if your assignment requires it. Report assembly point status to incident command or the arriving fire officer.

Hazardous Materials (Hazmat) Awareness

Security and patrol officers are trained to the awareness level only. This means you identify, isolate, and notify—you do not enter a contaminated area under any circumstances.

Identify. Use the Emergency Response Guidebook (ERG)—carry the current edition or access it on your phone. Read the placard on a vehicle or container: the four-digit UN identification number and the hazard class diamond give you the guide number in the ERG. That guide tells you the initial isolation distance and the recommended safe approach direction (generally from upwind, uphill, and upstream).

Isolate. Establish a perimeter at or beyond the ERG-recommended distance. Use cones, tape, or your vehicle to deny entry. No civilians, no fellow officers, and no you inside that perimeter until hazmat specialists declare it safe.

Notify. Radio dispatch with: your location, the placard information or description of the substance, visible signs (vapor cloud, leak, odor, victims), and wind direction. Request hazmat and EMS response. Remain at a safe distance and continue to relay information.

Safety-critical point: Entering the hot zone without proper chemical protective equipment (CPE) and respiratory protection is immediately dangerous to life and health. Exposure can incapacitate or kill within seconds. If you enter the hot zone without proper equipment during training or on the job, you have failed the most important safety standard of this lesson and must remediate before continuing.

Integrating All Three: General Principles

Radio early, radio often. Dispatchers coordinate all other agencies. Your first transmission starts that chain.
Document everything. Time of discovery, actions taken, personnel involved, and conditions observed.
Know your limits. Awareness-level hazmat, fire extinguisher use on small fires, and CPR/first aid are your tools. Anything beyond that belongs to the arriving specialists.
PPE before patient contact. Gloves are the minimum; eye protection and a mask may be required depending on the situation.
Hand off cleanly. A clear, concise verbal report to the arriving agency saves lives and protects you legally.

Key terms9

RACE protocolA four-step fire response framework: Rescue/Remove, Alarm, Contain, Extinguish or Evacuate; widely used in security and healthcare settings to guide patrol officers during fire discovery.

PASS techniqueThe correct method for operating a portable fire extinguisher: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.

ERG (Emergency Response Guidebook)A reference guide published by the U.S. Department of Transportation that provides hazmat identification, initial isolation distances, and protective action distances for first responders at the awareness level.

Awareness levelThe lowest tier of hazmat response training; personnel are trained only to recognize a potential hazmat release, protect themselves, call for help, and isolate the area—not to enter or mitigate.

Hot zoneThe area immediately surrounding a hazmat release where contamination or danger is highest; entry requires specialized chemical protective equipment and is prohibited for awareness-level personnel.

UN identification numberA four-digit number displayed on a hazmat placard or orange panel that identifies a specific hazardous substance or class of substance and is used to look up the correct ERG guide.

Patient hand-offThe structured verbal transfer of patient care and relevant information from the first responder on scene to arriving EMS personnel, including condition, actions taken, and any changes observed.

Scene safetyThe initial assessment a responder performs before approaching any emergency to identify hazards that could injure the responder; safety of the responder is evaluated before patient care begins.

Bloodborne pathogenInfectious microorganisms present in human blood and other body fluids that can cause disease in humans; patrol officers manage exposure risk by wearing gloves and appropriate PPE during all patient contact.

In class: CPR and first-aid integration review (building on Universal Core certification): students practice the patrol-specific protocol—radio dispatch first, then begin care—using a CPR manikin and AED trainer, with the instructor timing the sequence and evaluating radio transmission quality simultaneously. · Fire discovery drill on campus: students on patrol encounter a simulated fire alarm activation; they must follow RACE protocol (Rescue/Remove, Alarm, Contain, Extinguish or Evacuate), use a fire extinguisher on a controlled training prop, radio the situation correctly, and guide a simulated occupant to the assembly point. · Hazmat awareness scenario: instructor sets up a simulated chemical spill scene (colored water, placard mockup) in the parking lot; students apply the ERG (Emergency Response Guidebook) awareness-level process to identify the placard, establish a safe approach distance, deny entry, and coordinate with simulated fire department arrival—no entry into the hot zone is permitted.
Materials: CPR manikin, AED trainer, fire extinguisher (training unit, dry), RACE protocol reference card, Emergency Response Guidebook (current edition), hazmat placard mockups, radio, personal protective equipment, scenario briefing cards
Check: Field performance checklist for all three scenarios scored by instructor; student must achieve pass on every scenario individually (no single scenario below 80%) and must not commit any action that would endanger themselves or a simulated victim; failure of the safety-critical hazmat isolation step requires immediate remediation and re-demo.
