When pressurizing a hose for testing, firefighters should:

The main idea is to set up the hose so the test happens in a stable, controlled way. Laying the hose flat on the ground before charging provides a smooth, supported path for the water to flow. When the hose is flat, there are no coils or raised sections that can kink, pinch, or whip as pressure builds. This stable layout helps the hose and couplings seal evenly, reduces uneven stress on the material, and makes leaks easier to spot along the full length of the hose. It also minimizes dynamic reactions, like sudden movement or water hammer, that can occur if the hose isn’t well supported. By contrast, charging a hose that’s bunched, kinked, or elevated increases the chance of damage to the hose or fittings, makes the test results unreliable, and can create unsafe conditions for the crew. While it’s important to avoid exceeding the test pressure and to operate valves carefully, the safest, most effective setup for the actual pressurizing step is to lay the hose flat and evenly on the ground before charging.
