I have seen this but it is not very common. Sometimes a notched plug has
to be used so that the laser can be used in theatre but in this case it
is not a deliberate control measure. Occasionally the user wants an
usual plug fitted for control purposes. It does depend on the local
circumstances.

Subject: Laser safe mains sockets



Hi

One of the hospitals I am involved with has adapted mains sockets that
only allow mains plugs with a notched earth pin to be used in one of its
theatres.

Can I ask colleagues to let me know how common/ popular this practice
is by responding  a Yes or No to this e-mail.

If it is done off list, I shall send a summary to the list with the
results.

 

This allows the laser only to be used in that environment. Whilst this
is an engineering control to ensure the laser is used within the
controlled area only, 

The flexibility of some laser systems and theatre dynamics makes the
movement of systems a clinical need.

Clearly the notched plug can be removed/ or the mains lead replaced
with a standard plug lead

 

A potential incident has been reported where the flexibility of a
non-notched plug laser was attempted to be used in a non-defined laser
controlled area.

The administrative control caught this issue, but could easily be
surpassed.

 

Many thanks

 

Matt
