1. SCENE ASSESSMENT AND PPE: Confirm the scene is safe from ongoing structural hazards, hazardous materials, or active threats before entering. Don latex gloves immediately and direct a bystander or team member to contact advanced medical support with your precise location and casualty count.

2. INITIAL TRIAGE AND HEMORRHAGE CONTROL: Identify the casualty with the highest immediate life threat, prioritizing arterial or pulsatile bleeding. Apply the tourniquet high and tight on the affected limb to occlude arterial blood flow, and note the application time.

3. JUNCTIONAL AND WOUND HEMORRHAGE MANAGEMENT: For bleeding not amenable to tourniquet application, such as groin or axilla wounds, apply a BleedStop hemostatic bandage with firm direct pressure. Use multi-trauma dressings for large wound surfaces, eviscerations, or severe bleeding across broad tissue areas.

4. AIRWAY ASSESSMENT AND MANAGEMENT: Assess the unresponsive casualty for consciousness and spontaneous breathing. Open the airway using head-tilt and chin-lift or jaw-thrust if spinal injury is suspected. If trained and the casualty has no gag reflex, measure and insert a properly sized oral airway from the corner of the mouth to the angle of the jaw.

5. SECONDARY SURVEY AND EXPOSURE: Use EMT shears to cut away clothing, webbing, or boots to fully expose all injuries. Assess distal pulses, sensation, and motor function on any limb with suspected fracture, dislocation, or deformity.

6. MUSCULOSKELETAL STABILIZATION: Form the universal splint to match the injured limb and immobilize it in the position found. If the mechanism of injury suggests spinal trauma, apply the cervical collar using proper sizing and alignment technique.

7. HYPOTHERMIA PREVENTION: Cover all casualties with casualty blankets to retain core body heat. Hypothermia accelerates shock and increases mortality in trauma casualties, making this a clinical priority, not a comfort measure.

8. REASSESSMENT AND DOCUMENTATION: Reassess all applied interventions including tourniquet tightness, airway position, and dressing integrity. Use the stethoscope to auscultate breath sounds and heart sounds, and document all intervention times and findings for EMS handoff.

9. MINOR WOUND MANAGEMENT: Once all life threats are controlled, address secondary wounds using antiseptic wipes to clean the wound and surrounding skin. Apply sterile gauze as a primary dressing and use skin and eye wash for wound irrigation or debris flushing as indicated.

10. KIT SUSTAINMENT AFTER DEPLOYMENT: Immediately replace all expended components before restaging the kit. Conduct a full inventory, verify expiration dates on all sterile items, and inspect the pack, zippers, buckles, and MOLLE webbing before returning the kit to service.
