Summary of "1 RESCATE VEHICULAR EXPLICATIVO"

Summary of “RESCATE VEHICULAR EXPLICATIVO”

This instructional video, produced by the Secretariat of Public Security of the Federal District, the Rescue and Emergency Medical Squadron, and Urban Rescue Mexico, provides foundational guidelines and techniques for the extrication (rescue) of trapped or pinned patients from wrecked vehicles. It aims to introduce basic concepts and standardized cutting and rescue methods used by these professional groups, acknowledging the absence of formal national standards in Mexico.

Main Ideas and Concepts

Purpose and Context

• Introduction to vehicle extrication basics and cutting techniques.
• Acknowledgment of no current national standards for rescue activities.
• Emphasis on starting points and safety protocols in extrication.

Vehicle Anatomy Knowledge

Key vehicle parts rescuers must know:

• Tires, windows, windshield, front and rear doors.
• A-pillars, B-pillars, C-pillars.
• Catalytic converters.
• Supplemental Restraint System (SRS): airbags, gas cartridges, seatbelt pretensioners.
• Firewall separating passenger compartment from engine compartment.

Personal Protective Equipment (PPE)

• Safety footwear.
• Cotton coveralls (preferably fire-resistant).
• Nomex hood or coverall.
• Helmet.
• Eye protection.
• Gloves or firefighting protective gear.

Tools and Equipment

• Hydraulic tools powered by fluid pressure:
  • Types: cutters, spreaders, combination tools, rams.
  • Brands used: Lucas, Ancus, Genesis.
• Hand tools:
  • Holigan tool.
  • Cutting pliers or wrenches.
  • Window punch.
  • Fireman’s axe.
• Power tools:
  • Reciprocating saw.
• Basic materials:
  • Poles (short, long, ladder poles).
  • Flat webbing.

Team Roles and Organization

• Team of three rescuers:
  • Operator.
  • Support.
  • Motorcyclist.
• All team members must wear full PPE and be ready to relieve colleagues or intervene.

Scene Assessment and Safety

• Conduct a quick visual inspection upon arrival.
• Gather information from authorities and bystanders.
• Take control of the scene immediately.
• Request police assistance and backup if needed.
• Cordon off the scene with a minimum 3-meter perimeter per vehicle.
• Identify and minimize risks such as:
  • Open roads.
  • Fallen power lines.
  • Flammable liquids.
  • Hazardous materials inside the vehicle (weapons, toxic substances, animals).
• Keep all personnel visible and communicate constantly.

Vehicle Stabilization

Essential to prevent uncontrolled movements. Methods vary based on vehicle position:

• On four wheels: stack wooden blocks (“box of pallets”) under tires, deflate tires.
• Upside down on roof: use ladder pallets and long pallets as struts.
• Upside down on side: use wedges and long pallets secured with straps.

Accessing the Vehicle Interior

• Natural access: doors.
• When doors cannot open, create access via side windows.
  • Side windows: tempered glass, breaks into small sharp pieces.
  • Tape windows star-shaped with 5 cm wide adhesive tape to contain fragments.
  • Tools for breaking glass:
    • Holigan tool (used with axe or sledgehammer).
    • Window punch (single-person tool).
  • Remove shattered glass carefully.
• Windshield: laminated glass with plastic film.
  • Does not shatter; cut with axe, hand saw, or electric saw.

Dealing with Supplemental Restraint Systems (SRS)

• Airbags and gas cartridges in seatbelt pretensioners pose risk.
• Use airbag protectors on steering wheel and dashboard to prevent injury from undeployed airbags.
• Locate and mark gas cartridges to avoid cutting them.
• Curtain airbags in pillars are a known risk without current protective devices.

Hydraulic Tool Usage for Vehicle Opening

• Start with doors (hinge side or lock side).
• Create space using Holigan tool or expander to expose locks, bolts, or hinges.
• Break two hinges or locks securing the door.
• Secure removed door with strap or rope to keep it clear of work area.

Advanced Cutting Maneuvers

• Third door or full side opening:
  • Open front door, cut B-pillar top and bottom.
  • Remove both doors together to create larger access.
• Half roof removal:
  • Remove windshield, front windows, doors.
  • Cut A-pillars ~15 cm from body.
  • Cut B-pillars above seatbelt.
  • Make relief cuts between B and C pillars to fold roof back.
• Full roof removal:
  • Remove windshield, windows, front and rear doors.
  • Cut A, B, and C pillars (above seatbelt).
  • Support roof during cutting to prevent falling on occupants.

Firewall Displacement Maneuver

• Used when dashboard presses on occupants’ legs (common in frontal impacts).
• Vehicle must be perfectly stabilized.
• Remove windshield, front doors, and roof or half roof.
• Make relief cuts on front door frames.
• Place hydraulic ram diagonally between B-pillar and A-pillar section.
• Slowly expand ram to push firewall and dashboard away, creating space.
• If ram unavailable or too small, use expander or combination tool with relief cuts.
• Expand slowly to create enough space for safe extraction.

Methodology / Step-by-Step Instructions (Key Procedures)

1. Scene Safety and Assessment

   • Visual inspection.
   • Secure scene with police and cordon.
   • Identify hazards (external and internal).
   • Communicate and monitor all personnel.

2. Vehicle Stabilization

   • Determine vehicle position.
   • Use wooden blocks, pallets, wedges, and straps accordingly.
   • Deflate tires if vehicle on wheels.

3. Access Creation

   • Attempt door opening.
   • If doors jammed, break side windows safely (tape, break, remove glass).
   • Remove windshield if needed.

4. Handling SRS

   • Locate airbags and gas cartridges.
   • Mark and avoid cutting gas cartridges.
   • Use airbag protectors on steering wheel and dashboard.

5. Cutting and Opening

   • Use hydraulic tools to cut hinges or locks.
   • Secure removed doors.
   • Perform third door/full side opening if more space needed.
   • Remove half or full roof for better access.

6. Firewall Displacement

   • Stabilize vehicle.
   • Remove windshield, doors, roof.
   • Make relief cuts.
   • Use ram or expander to push firewall/dashboard away.
