What is the first action that should be taken for packing that is leaking at a slow rate?

When dealing with a packing that is leaking slowly, the first step to take is to observe the situation. This allows for an assessment of the nature and severity of the leak. By observing, operators can determine if the leak is stable, worsening, or fluctuating. Observing also helps identify if the leak is due to vibration, temperature change, or other operational factors that could impact the performance of the packing.

Observing further aids in understanding the context—whether the equipment can continue to operate safely and efficiently while the situation is monitored or if immediate action is required. It also allows the operator to decide on the best course of action later, based on firsthand knowledge of the leak's behavior, helping to minimize waste and downtime.

In contrast, actions such as replacing the packing material or increasing pressure may not be necessary if the leak is manageable, while applying lubrication could only temporarily mask the issue without addressing any underlying problems. Therefore, careful observation is a critical first step in effectively managing any leak in a packing system.
