Which lifting device is considered the least secure?

The horsecollar is regarded as the least secure lifting device due to its design and application limitations. While it can be effective in certain situations, it does not provide the same level of stability and support as other options. The structure of a horsecollar may not secure the individual as tightly, particularly in turbulent or unpredictable water conditions, which could lead to slippage or inadequate support during a rescue operation.

In comparison, devices like the water basket and soft bags are specifically engineered to secure and stabilize a person during a rescue, often accommodating the need for additional safety features and support. The screamer suit is designed to provide fit and security for a rescuing individual, allowing for a secure hold in water rescues. These features collectively render the horsecollar less reliable when it comes to securing and lifting a victim in water rescue scenarios.
