What happens if pressure is not removed from the hoseline before opening an automatic hose connection?

Opening an automatic hose connection while pressure remains in the hoseline can lead to personal injury. This situation arises because the buildup of pressure can cause a sudden release of water or pressure upon opening, which could unexpectedly forcefully push water or the hose out, posing a risk to anyone nearby. The force and unpredictability of high-pressure water can lead to situations where an individual could be struck or incapacitated, leading to serious injuries.

Additionally, there are safety protocols specifically designed to mitigate these risks, emphasizing the importance of relieving pressure before attempting to connect or disconnect hoses. This practice ensures a controlled and safe operation while working with pressurized systems, thereby minimizing the potential for accidents.
