accidents are a leading cause of death, with over 10,000 fatalities each year. One of the most critical aspects of post-accident rescue is vehicle stabilization. This step is essential to avoid further harm to those trapped inside the vehicle and to provide a safe environment for rescue workers. Without proper stabilization, a vehicle may shift or tilt, posing significant risks to both the rescuers and the victims. This article explains in detail the importance of vehicle stabilization, the techniques used, and practical tips for ensuring a safe and effective rescue.

Importance of Vehicle Stabilization

Vehicle stabilization is the foundation of safe rescue operations. Without it, even the most experienced rescuers face the risk of injury or worsening the situation for accident victims. A vehicle that is not properly stabilized may unexpectedly move due to its weight distribution or external forces. This could cause further injury to those inside or jeopardize the safety of rescue personnel.

When a vehicle is involved in a serious accident, it is often left in precarious positions—on its side, upside down, or on an incline. In such cases, any movement can be dangerous. Stabilization ensures that the vehicle remains in place, allowing rescuers to work without fear of sudden movements. Additionally, proper stabilization allows rescuers to access victims more efficiently, reducing the time needed to extract them from the wreckage.

Key Factors to Consider in Vehicle Stabilization

Stabilizing a vehicle is not a one-size-fits-all process. Each accident presents unique challenges that require rescuers to adapt their approach based on several critical factors.

• Position: The position of the vehicle determines how it should be stabilized. For example, a vehicle on its side requires different techniques than one resting on its roof. Rescuers must assess the vehicle’s resting position to determine the best stabilization method.
• Shape: The design of the vehicle and the extent of its damage influence how it can be stabilized. A heavily damaged vehicle may have compromised structural points, making some methods of stabilization less effective.
• Size: Larger vehicles, such as trucks or buses, require more advanced stabilization techniques compared to smaller cars. The weight and height of the vehicle impact the type of equipment needed to secure it.

Understanding these factors allows rescuers to choose the appropriate tools and methods for the situation, ensuring that the vehicle remains stable throughout the rescue process.

Two-Step Approach for Vehicle Stabilization

A successful vehicle stabilization process is generally carried out in two phases: primary stabilization and secondary stabilization. Each phase is essential for maintaining control over the vehicle’s movements.

Primary Stabilization

The goal of primary stabilization is to prevent any immediate movement of the vehicle. This is typically done by securing the vehicle to the ground using basic stabilization tools such as blocks, chocks, and wedges. These tools create firm contact points between the vehicle and the ground, preventing the vehicle from sliding or shifting.

• Using blocks, chocks, and wedges: These tools provide immediate stability by anchoring the vehicle in place. They are positioned around the vehicle’s wheels and key contact points with the ground to create a firm, level surface.
• Creating flat stability: The purpose of primary stabilization is to make the vehicle as stable as possible on a flat plane. This process is quick and crucial for securing the vehicle before any further rescue steps are taken.

Secondary Stabilization

Once primary stabilization has been achieved, rescuers move on to secondary stabilization. This step focuses on preventing the vehicle from moving in three dimensions—vertically, horizontally, or rotationally.

• Using rescue struts and power shores: These specialized tools provide added support by bracing the vehicle at key points. They are placed between the vehicle and either the ground or another stable surface to prevent the vehicle from tipping, rolling, or collapsing.

Secondary stabilization ensures that the vehicle remains completely immobile during the extraction process, allowing rescuers to safely access the victims and work without interruption.

Practical Tips for Effective Vehicle Stabilization

To carry out successful vehicle stabilization, rescuers must have the right skills and knowledge. Simply having the tools on hand is not enough. Rescuers need to understand how and when to use them effectively.

1. Skills and Knowledge: Every rescue worker involved in vehicle stabilization must be trained in both primary and secondary stabilization techniques. Knowing which equipment to use and how to operate it is essential for a successful rescue. Additionally, rescuers must be able to quickly assess the situation and determine the appropriate method for stabilization.
2. Planned Equipment Placement: One of the most common mistakes in vehicle stabilization is placing equipment without a clear plan. Incorrectly placed stabilization tools can cause the vehicle to move unexpectedly during rescue operations, endangering everyone involved. Rescuers must carefully plan where and how to position blocks, chocks, and other equipment to ensure stability without hindering access to the victims.

Vehicle Weight Consideration

One of the most important factors to consider when stabilizing a vehicle is its weight. The tools and techniques used must be able to support the vehicle’s full weight without risk of failure. Rescue workers need to be familiar with the approximate weight of various vehicle types to select the correct equipment for the job.

• Compact cars: Weigh around 2,000 kg.
• Midsize cars or sedans: Weigh around 2,500 kg.
• Small trucks, vans, and SUVs: Weigh around 3,500 kg.
• Large trucks: Weigh around 10,000 kg.

Using equipment that is not rated for the vehicle’s weight can result in collapse or failure during stabilization, posing serious risks to both rescuers and victims. Rescuers must ensure they have the appropriate tools for the job before beginning the stabilization process.

NFPA 1006 Standards for Vehicle Rescue

The NFPA 1006 standards are guidelines developed to ensure rescuers are properly trained and equipped to handle vehicle rescue operations. These standards outline the necessary skills and qualifications for rescuers at various levels, from basic awareness to advanced technician roles.

Vehicle and Machinery Rescue in NFPA 1006

This section of NFPA 1006 focuses specifically on the stabilization of vehicles and small machinery during rescue operations. It provides clear instructions on how to safely stabilize vehicles and ensure that they do not move during the rescue process.

• Stabilization: The primary goal is to keep vehicles or machinery stable during the rescue. Any movement could jeopardize the operation and put both victims and rescuers at risk.
• Minimize risks: Rescuers must prioritize their safety and reduce risks by following proper stabilization techniques and using appropriate tools.
• Necessary knowledge: Rescuers must understand which types of stabilization equipment are available and the best methods for using them based on the vehicle’s design and damage.

Stabilizing Unstable Vehicles

Unstable vehicles pose a significant challenge in rescue operations. These vehicles are often found in unusual positions after a collision—on their side, upside down, or leaning against other objects. In these situations, stabilization is critical for keeping the vehicle from moving further and creating additional hazards.

Rescuers must be prepared to address the unique challenges posed by unstable vehicles, using specialized tools and techniques to ensure the vehicle remains secure.

Common Vehicle Stabilization Methods

Several methods can be used to stabilize vehicles during rescue operations. Each method is designed to provide support and prevent the vehicle from moving.

• Box cribbing: Involves placing wood or plastic blocks around the vehicle to prevent movement.
• Struts: Extendable supports used to brace specific parts of the vehicle.
• Step chocks: Wedge-shaped tools that support the vehicle’s slope.
• Wedges and shims: Small adjustments made using thin boards or wedges to secure the vehicle.
• Ratchet lever jacks and stabilizer jacks: Used to lift and stabilize the vehicle.
• Ropes, chains, and cables: Secure the vehicle to nearby structures or objects.
• Winches and ratchet straps: Provide tension to keep the vehicle in place.

Each method is selected based on the type of vehicle and its position, ensuring the best possible stabilization.

Steps for Vehicle Rescue

1. Step 1: Size-Up – Assess the situation and evaluate the vehicle’s position.
2. Step 2: Vehicle Stabilization – Secure the vehicle using the appropriate tools and techniques.
3. Step 3: Vehicle Extrication – Begin the process of removing the victims from the vehicle.

By following these structured steps, rescuers can ensure a safe and efficient rescue operation, minimizing risks and maximizing the chances of a successful outcome.
