Which method is used for breaking tight couplings without the use of a spanner wrench?

The Stiff Arm Method is recognized for its effectiveness in breaking tight couplings without requiring tools like a spanner wrench. This technique involves the firefighter using their arm to apply a force against the coupling, leveraging body mechanics effectively to create enough torque to loosen the connection.

By positioning the arm correctly and utilizing the body's strength, it allows for a more controlled and safer approach, minimizing the risk of injury and avoiding the need for additional equipment. This method is particularly useful in situations where access to tools is limited or when time is of the essence.

Using this method enhances the firefighter's ability to respond quickly and efficiently under stressful conditions when dealing with tightly connected hose couplings or similar fittings.
