Objective. Students will execute the correct notification, evacuation, and scene-protection steps for three emergency types—fire alarm activation, medical emergency, and active-threat indicator—within the time and accuracy standards of a site emergency action plan.
This lesson, its worked examples and its practice questions has not yet been verified by a licensed professional in the field or by a certification or approval body. It is a study draft and may contain errors. Do not use it as instructions for work on a job site or on live equipment. Always follow your instructor, your supervising professional, and current official references and regulations.
VoTechWorks program approval and accreditation are still in progress. Credentials are issued only by the certifying bodies named in each program, after their own exams.
Security officers are almost always the first uniformed personnel on scene when an emergency develops. Law enforcement, fire, and EMS may be minutes away. Those first minutes determine whether people survive, whether a fire spreads, and whether a threat escalates. Your job is not to replace firefighters, paramedics, or police—it is to initiate the right actions immediately, keep people calm and moving, preserve the scene where appropriate, and hand off a clear, accurate situation report to incoming responders.
Every facility where you work is required by OSHA to maintain a written Emergency Action Plan (EAP). You must know the EAP for each site before you begin a post.
An EAP is a site-specific document that identifies:
During orientation for any new post, walk the building with the floor plan in hand and confirm that posted signage matches the EAP. Note locked stairwells, occupants with mobility limitations, and any areas that require a key or access card to exit.
When a pull station activates or a smoke detector triggers the panel:
1. Treat every alarm as real until confirmed otherwise by the fire department.
2. Call 911 immediately — give address, building name, floor, and nature (fire alarm, possible smoke, confirmed flame).
3. Activate or confirm the building alarm if not already sounding.
4. Begin evacuation — use the public-address system or verbal direction to move occupants to the nearest exit and on to the assembly point.
5. Sweep assigned zones — check restrooms, conference rooms, and any area where someone might not hear the alarm. Do not use elevators.
6. Confirm headcount at the assembly point — compare to any occupancy log or visitor sign-in sheet.
7. Radio dispatch or the command post — report location, headcount confirmed or missing persons, and any observed smoke or flame.
8. Do not re-enter until fire department gives the all-clear.
Safety note: Never prop fire doors open during evacuation. They are rated barriers designed to slow fire spread.
When someone collapses or reports a medical complaint:
1. Ensure scene safety — identify hazards before approaching (chemical spill, electrical, crowd pressure).
2. Call 911 — state your location, the number of patients, and observed signs (unresponsive, not breathing, bleeding).
3. Begin care within your training level — if you are trained in CPR/AED, begin immediately for an unresponsive, non-breathing patient; control severe bleeding with direct pressure if trained.
4. Send someone to meet EMS at the building entrance and escort them to the patient.
5. Clear bystanders — limit crowding to protect patient dignity and give responders room to work.
6. Preserve any relevant scene evidence — if the cause is unknown or suspicious, do not move objects around the patient.
7. Document — record time of discovery, actions taken, and names of witnesses.
An active threat is any report or observation suggesting that a person is using or is about to use deadly force against people at your location. Common indicators include gunshots, a person brandishing a weapon, or a credible witness report.
1. Call 911 immediately — provide address, building or lot location, description of the subject (clothing, direction of travel, weapon description), and number of known victims.
2. Initiate the site's active-threat protocol — this may be a lockdown announcement, an evacuation, or both, depending on the EAP.
3. Do not attempt to confront or apprehend unless you are trained and authorized and circumstances absolutely require immediate intervention to prevent imminent loss of life.
4. Direct people away from the threat — move them out of the building or into locked, interior rooms depending on threat location.
5. Establish a perimeter at a safe distance — keep bystanders away from the area and designate a clear route for responding law enforcement.
6. Meet law enforcement at a safe point outside and brief them: subject description, last known location, number of victims, and any access control issues (locked doors, badge readers).
7. Keep your hands visible when law enforcement arrives — officers entering an active scene cannot immediately distinguish security from a threat.
The Incident Command System (ICS) establishes a clear chain of communication so that every message goes to the right person without duplication or contradiction. In a site emergency your typical chain is:
Officer on scene → Site supervisor / dispatch → Incident Commander (often the senior officer or responding fire/police commander) → Agency dispatch
Every radio message should include three elements: location, nature of the emergency, and headcount or status. Missing any element forces responders to ask follow-up questions that waste critical seconds.
Answer each question, then check it. Nothing is recorded; this is your own practice.
