Moving and Removing the Roof

Rescue personnel often remove part or all of a vehicle’s roof to access trapped victims. Removing the roof also deactivates systems like side-impact protection systems (SIPS) or inflatable window curtains. In collisions or rollovers, roofs can collapse or become compressed, requiring rescuers to move or remove them using tools like cutters, reciprocating saws, or air chisels. The technique chosen depends on the patient’s condition and the available access.

Rescue teams may use tools like hydraulic rams or spreaders to widen openings, creating more space inside the vehicle. If these methods fail, the entire roof may need to be removed or folded back. Before cutting, rescuers must carefully check and remove parts like seatbelt pretensioners and side airbags to avoid damaging them.

Removing the Vehicle Roof: Key Points

Vehicle designs often integrate the roof and doors into the car’s structural integrity. Removing these components can compromise the vehicle’s stability and create risks. Rescue teams must stabilize the car using steps or chocks under its pillars before roof removal.

Modern vehicles rely heavily on the windshield, A-pillars, and front roof edge for structural support. These should be preserved whenever possible. The typical process involves cutting the roof at the top of the A-pillars, followed by cutting the remaining door posts to lift the roof off.

Rear pillars are often challenging to cut due to their width, which may exceed the opening capacity of hydraulic cutters. In such cases, rescuers can cut triangular sections from one side of the pillar to allow deeper insertion of the cutter. Alternatively, a spreader can compress the pillar to make it smaller.

This method ensures safe roof removal, enabling rescuers to reach trapped victims effectively while maintaining safety precautions.

Roof Access in Overturned Vehicles

Accessing a vehicle’s interior through the roof is an effective rescue method, especially when the vehicle is overturned. To ensure safety, rescuers must stabilize the vehicle by inserting cribbing between the car and the ground. This minimizes movement caused by gaps.

Specialized rescue tools like air knives and reciprocating saws can be used to cut the roof efficiently and quickly. This method is particularly useful in emergencies where traditional access points like doors are damaged, or immediate access to victims is critical.

Roof Removal Technique

Step 1: Remove the Glass Begin by safely removing all vehicle glass to prevent injuries to rescuers or victims during later operations.

Step 2: Cut the First Pillar Start by cutting the pillar furthest from the victim to minimize risk. This alters the roof’s structure while keeping the victim safe.

Step 3: Cut Remaining Pillars Proceed to cut the other pillars one by one, leaving the one closest to the victim for last. Ensure the roof remains stable throughout the process.

Step 4: Address Oversized Pillars If a pillar is too large for the cutter, use one of these techniques:

• Cut a triangular section from one side of the pillar for deeper cutter insertion.
• Cut one side of the pillar and move the cutter to the opposite side to complete the cut.
• Compress the pillar with a spreader to reduce its size.

Step 5: Remove the Roof Once all pillars are cut, carefully lift the roof away, considering its weight and balance to prevent accidents.

Following these steps allows rescuers to access victims efficiently while prioritizing their safety.

Roof Removal Technique for Overturned Vehicles

Step 1: Remove Glass Safely remove all glass. Strip the interior trim along the roof rails and pillars to expose hidden safety devices like gas cylinders and airbag systems. Treat undeployed airbags as active, taking extreme care.

Step 2: Cut High-Side Pillars Cut the roof pillars on the high side of the vehicle to begin detaching the roof’s structure.

Step 3: Cut Lower Pillars Horizontally Make low horizontal cuts on the lower roof pillars to further prepare the structure for removal.

Step 4: Support the Roof Insert cribbing between the roof and the vehicle’s underside for stability. This prevents additional hazards during the operation.

Step 5: Fold Roof Outward Fold the roof outward, making deeper or additional cuts as needed to completely separate it from the vehicle.

Step 6: Fully Remove the Roof Cut the lower pillars to fully detach and remove the roof. This creates maximum access to the victim and must be performed with caution.

These steps ensure that rescuers can remove an overturned vehicle’s roof effectively and safely, enabling quick and safe access to trapped victims.
