What is the two-fire fighter stiff-arm method used for?

The two-firefighter stiff-arm method is primarily used for uncoupling hose, particularly when dealing with heavy or tightly connected parts. This technique involves two firefighters working together to provide the required leverage and force needed to safely separate hose couplings, which can be difficult if they are under pressure or have been in place for an extended period.

In this method, each firefighter uses one arm to grip a portion of the hose, allowing them to use their body weight and strength in unison to push against the coupling. By coordinating their actions, they can effectively overcome the resistance and achieve a successful uncoupling without the risk of damaging the hose or injuring themselves.

Utilizing this technique improves safety and efficiency in operations, especially in high-pressure situations where rapid access to equipment is essential.
