broken wafer in the right bath

This has happened to me twice in the last few days so I thought I'd  
send a message to the list:

If you happen to break a wafer in the acid baths please take the time  
to at least let people know. You may not care but there are people  
who'd rather avoid a single scratch on their samples in this lab.

I don't know how safe it is to risk draining the broken wafer pieces  
up the pipes- I realized this as I was changing chemicals and left the  
right bath drained halfway.

Thanks,
Caner.
