2. PERFORMING THE ONE-PERSON FOOT-TILT METHORD Place one foot on the hose behind the male coupling. push down with your foot to tilt the male coupling upward. place the other hand behind the female coupling and grasp the hose.

3. PERFORMING THE TWO-PERSON METHORD Pick up the male end of the coupling. Grasp it directly behind the coupling and hold it tightly against the body. The second brigade member hold the female coupling firmly with both hands. The second brigade member brings the female coupling to the male coupling. . The second brigade member aligns the female coupling with the male coupling

4. The second brigade member turns the female coupling counter clockwise until it clicks. Turn the female coupling clockwise to couple the hoses .

5. PERFOMING THE ONE-PERSON KNEE-PRESS METHORD Pick up the connection by the female coupling end. Turn the connection upright resting the male coupling on a film surface. Place a knee on the female coupling and with body weight press down. Turn the female swivel counterclockwise and loosen the coupling.

6. PERFORMING THE TWO-PERSON STIFF-ARM METHORD Two brigade member face each other and firmly grasp their respective coupling. With elbows locked straight, the brigade members push toward each other. While pushing toward each other, the brigade members turn the coupling counter clockwise, loosening the coupling.
