What is the first step to take if there is leaking from around the packing gland?

When dealing with leaks from around the packing gland, the initial step should indeed be to tighten it. This is because many leaks occur due to the packing becoming loose over time, often as a result of normal wear and tear during the operation of the valve or pump.

By tightening the packing gland, the material is compressed more firmly against the shaft, which can help close up any gaps that may have formed and effectively stop the leak. This is a quick and often effective first measure before considering more extensive repairs or replacement of components.

Furthermore, if tightening does not resolve the leak, then additional steps like inspecting for corrosion, replacing the packing, or applying sealant may be necessary. However, these actions take more time and resources, making tightening the packing the most sensible first approach in addressing the issue efficiently.
