Before opening an automatic hose connection, why is it important to remove pressure from the hoseline?

Removing pressure from the hoseline before opening an automatic hose connection is crucial primarily to avoid personal injury. High pressure in a hose can result in sudden and uncontrolled water release when the connection is opened, potentially leading to injuries from the force of the water or from being struck by the hose itself. This safety measure helps protect the individual handling the connection and ensures that the process of connecting or disconnecting hoses can be done more safely.

While considerations like preventing hose damage and ensuring proper connection may also be important, the immediate concern for personal safety takes precedence. Reducing pressure mitigates risks effectively, allowing the worker to focus on the operation without the threat of injury from unforeseen hydraulic forces.
