Do Not Modify Pressure Regulator Inlets

 

Distribution:      

Work Place notice boards together with safety meeting.

 

To avoid confusion and danger, cylinder and pack suppliers differentiate between 300 Bar and 230 Bar by fitting different types of non-interchangeable outlet connections as follows:

 • 300 Bar - have a New European Valve Outlet Connection (NEVOC).

• 230 Bar - have the standard BS 341 outlet connection.

This Safety Alert has been raised because there is anecdotal evidence that a 300 Bar regulator may have been modified to fit a 230 Bar source by removing the NEVOC fitting and replacing it with a BS 341 fitting. Clearly, if the reverse was to happen – a 230 Bar regulator modified to fit a 300 Bar source – the consequences could be grave, therefore:

 

Regulator inlet connections shall not be modified

 

Additional points to remember when selecting regulators and pressure testing:

 • You must be trained and approved by your Manager to conduct pressure testing.

• You must be accompanied by an aditional engineer during Strength testing.

• Always double check the contents of the cylinder or pack for type of contents and pressure.

• Ensure that the regulator you have is suitable for the pressure and has the correct fitting.

• Select the lowest available maximum outlet regulator (Do not use a 175 Bar outlet regulator for a 27 Bar test, use a 40 Bar outlet regulator instead).

• You must follow method statement..
