RE: UV lamps

["Stephen Brown" <swbrown@vivalis.com>(by way of John Dolman<moderator@the-dolman-consultancy.com>)]

Dear Mohan,
 
What are you using the UV lamp for ? For example, in a water loop ?, or
safety cabinet ? The use and quality risk is not the same. When the
system was installed and qualified your supplier should have specified
the appropriate lifetime for the UV lamp. All that should be documented
in the equipment file and operating procedure. I assume that you have
been logging (documenting) hours of use in the equipment's log book. The
efficiency of the lamp will decline with use. I strongly suggest you
replace the lamp according to the manufacturer's recommendations
otherwise you may end up using a lamp that is not working correctly.
Alternatively, depending on the risk, if you consider that the lamp is ok
and have demonstrated this, you could consider a change control and
modify your maintenance programme accordingly.
 
Regards,
 
Stephen Brown
