10.3 First Aid Fundamentals
Key Takeaways
- Emergency First Aid is required by most BC security employers and bundled by most BST providers, but it is not a Security Worker Licence requirement; the guard is often the first person on a medical scene.
- Scene safety comes first — do not become a second victim; check for hazards before approaching any casualty.
- The emergency action principles are Check, Call, Care: check the scene and the person, call 911, then provide care within your training.
- The primary survey covers Responsiveness, Airway, Breathing, and Circulation; life-threatening problems are found and managed in that order.
- A security worker's first-aid role is limited by training; do no harm, stay within scope, and document every action taken and time.
10.3 First Aid Fundamentals
Quick Answer: A BC security worker is often the first person on a medical scene, and Emergency First Aid is required by most BC security employers alongside BST, though it is not a licensing requirement. Your role is to make the scene safe, call 911, and provide care within your training until paramedics arrive. The rule that overrides every other is scene safety first — do not become a second victim. A guard who collapses in a hazardous scene has turned one emergency into two.
Why This Matters for the BST Exam
First-aid questions test whether the candidate can sequence the response correctly — Check, Call, Care — and stay within the security worker's limited scope. The exam distractors are almost always actions that exceed scope (administering medication, moving a suspected spinal injury, diagnosing) or actions that ignore scene safety (entering a downed-electrical scene, a gas-filled room, or a violent scene to give care). The correct answer keeps the guard safe, activates professional help early, and provides only trained care.
The Security Worker's First-Aid Role and Co-Requirement
A BC Security Worker Licence is issued under the Security Services Act. In practice, most employers require Emergency First Aid (or equivalent OFA Level 1) certification alongside BST before a guard works a shift, even though the Registrar does not make it a condition of the licence. The guard is not a paramedic and does not diagnose or treat beyond training; the role is to:
- Be first on scene and recognize a medical emergency.
- Ensure scene safety.
- Call 911 and provide accurate information.
- Provide care within the scope of the certification held (e.g., CPR, AED, basic bleeding control, recovery position).
- Protect the casualty, preserve dignity, and document.
Emergency Action Principles: Check, Call, Care
The three-step model taught in Emergency First Aid and tested on the BST exam:
| Step | What you do |
|---|---|
| Check | Check the scene for hazards (fire, traffic, electrical, gas, violence, bloodborne pathogens). Then check the person: responsiveness, breathing, bleeding. |
| Call | Call 911 (or direct someone to call). State location, number of casualties, nature of the emergency, and any hazards. |
| Care | Provide care within your training: airway, breathing, circulation, bleeding control, recovery position, shock management, CPR/AED. |
Check-Call-Care Checklist
- Scene safe to approach? If no, do not enter; call 911 and control bystanders.
- Hazards identified and managed (traffic, fire, electrical, violence, body fluids)?
- Casualty responsiveness checked (tap and shout).
- Breathing checked (look, listen, feel for no more than 10 seconds).
- 911 called or bystander directed to call?
- Care provided within training only.
- Casualty monitored until EMS arrives.
- Incident documented with times.
The Primary Survey
The primary survey finds and manages life-threatening problems in priority order. The standard sequence is R-A-B-C:
| Step | Check | Action if problem found |
|---|---|---|
| R — Responsiveness | Tap shoulder and shout. Does the person respond? | No response → call 911 and proceed to A. |
| A — Airway | Is the airway open? Look for obstruction. | Open airway (head-tilt/chin-lift or jaw thrust if spinal injury suspected). |
| B — Breathing | Look, listen, feel for breathing (no more than 10 seconds). | Not breathing normally → start CPR; if breathing, place in recovery position. |
| C — Circulation | Check for severe bleeding. | Control life-threatening bleeding with direct pressure. |
Life-threatening problems are addressed in this order: an unresponsive person with a blocked airway dies before a breathing person with a bleeding wound, so airway comes before circulation. Once the primary survey is complete and life threats are managed, a secondary survey (signs, symptoms, SAMPLE history) may follow if trained.
When to Call 911
Call 911 immediately for:
- Unresponsiveness or changing level of consciousness.
- Breathing difficulty or not breathing normally.
- Chest pain or pressure suspected to be cardiac.
- Severe bleeding that cannot be controlled with direct pressure.
- Suspected stroke (face droop, arm drift, slurred speech).
- Seizures, severe burns, major fractures, or suspected spinal injury.
- Any situation where you are unsure — when in doubt, call.
A common exam trap is the option to drive the casualty to hospital yourself. Do not. Call 911 so that paramedics with the right equipment and drugs begin treatment en route.
CPR and AED Awareness
Cardiopulmonary resuscitation (CPR) keeps oxygenated blood flowing to the brain when the heart has stopped. For the public and for security workers without a current health-care-provider level, hands-only CPR (continuous chest compressions, no rescue breaths) is the standard for an unresponsive adult not breathing normally:
- Place the heel of one hand on the centre of the chest, the other hand on top, interlock fingers.
- Push hard and fast: at least 5 cm depth, 100-120 compressions per minute.
- Allow full chest recoil between compressions.
- Continue until an AED is ready, EMS arrives, or the person shows signs of life.
An Automated External Defibrillator (AED) analyses the heart rhythm and can deliver a shock to restore a normal rhythm. AEDs are designed for lay use: turn it on and follow the voice prompts. Pads go on a bare chest as shown on the pad illustrations. The AED will not shock a rhythm that does not need one. Minimize interruptions to chest compressions while the AED is analyzing.
Bleeding, Recovery Position, and Shock
Severe bleeding: control with direct pressure using a clean dressing and gloved hand. Add dressings, do not remove soaked ones. Only use a tourniquet if trained, direct pressure fails, and the wound is on a limb.
Recovery position: an unresponsive but breathing person is placed on their side, airway open, to keep the tongue from blocking the airway and to allow fluids to drain. Use when the person is breathing normally but not responsive, and when spinal injury is not suspected.
Shock: signs include pale cool clammy skin, rapid weak pulse, rapid breathing, restlessness, and altered consciousness. Management:
- Call 911.
- Keep the person lying down (unless that causes harm).
- Cover with a blanket to keep warm; do not overheat.
- Do not give food or drink.
- Reassure and monitor until EMS arrives.
Limits of the Security Worker's First-Aid Role
A guard works within the scope of the first-aid certification held and no more. Out-of-scope actions include:
- Administering medication (the casualty's own prescribed medication, such as an EpiPen or nitroglycerin, is generally administered by the casualty; the guard may assist only as trained and permitted).
- Diagnosing a condition or stating a cause.
- Moving a casualty with a suspected spinal injury unless there is an immediate life threat (fire, flood, collapsing building).
- Performing skills not covered in the certification.
The principle is do no harm — if an action is outside your training, do not do it. Call 911, keep the person safe, monitor, and wait for paramedics.
Documentation of First Aid Given
Every first-aid event is documented, typically on a site incident report and, if applicable, a first-aid record. Record:
- Time and location of the incident.
- What you found on arrival (scene, casualty condition).
- Actions taken and times (e.g., 911 called at 22:14, CPR started at 22:16, AED applied at 22:19).
- EMS arrival time and handover.
- Witnesses and bystanders.
- Your name, licence number, and first-aid certification.
Accurate documentation supports continuity of care, protects the guard legally, and is an exam expectation.
Key Takeaway
The BST first-aid answer follows a pattern: scene safe first, call 911 early, provide care within training, document. Any answer that has the guard entering an unsafe scene, exceeding scope, delaying 911, or moving a casualty without justification is wrong.
A guard responding to a collapsed person in a parking lot sees a downed power line across a puddle near the casualty. What is the correct first action under the Check-Call-Care model?
An unresponsive adult is not breathing normally after the airway is opened. The guard holds a current Emergency First Aid certificate but not a health-care-provider level. What is the correct action?
Which of the following is outside the scope of a security worker's first-aid role and must not be done?
During a first-aid event, the guard calls 911 at 22:14, begins CPR at 22:16, and hands over to EMS at 22:31. What does the BST exam expect the guard to do with this information?
