If you suspect that an air line is contaminated, what should you do first?

When you suspect that an air line is contaminated, giving it a blast of air while uncoupled is a recommended action because it serves as a preliminary step to clear out any debris or contaminants that may be affecting the system. This method allows for the assessment of the line’s condition and can help dislodge foreign materials. Ensuring the line is uncoupled during this procedure is crucial for safety and effectiveness, as it reduces the risk of pressurizing the entire system, which could lead to unintended consequences or injury.

This approach can also help you determine if the contamination is severe enough to warrant further action such as inspection or replacement—actions that could be more involved and time-consuming. It provides a quick and efficient means to troubleshoot the potential issue before advancing to more extensive measures like soaking in cleaning solutions or replacing lines.
