Hi,
Today I was doing some repair/cleaning of R&S modules for the CRTU.
I took the RF frontend, opened it, cleaned it and only after some time did I notice a warning sticker: "BERILYMUM OXID - SICHERHEITSHINWEISE BEACHTEN - OBSERVE SAFETY INSTRUCTIONS".
F*CK! I googled Beryliumoxide and indeed, toxic, hazardous, cancer inducing, ...
I washed my hands and face, gurgled water through mouth and nose and cleaned everything. I know, I am paranoid.
Why did I not notice this sticker before?
What ARE the safty instructions?
Where is the berylium oxide?
This led me to think on how dangerous is can be, to purchase older second hand test equipment on ebay and then opening it for cleaning and repair.
What are the most common dangerous substances found in eelctronic test equipment? I think i.e. about a rubidium time module, etc.
How to deal with it? Should common people even be allowed to buy/sell these things?
Interestingly, I did not see this topic being discussed here. I did not especifically search for it, but I wonder if it wouldn't make sense to put a sticker on top of this forum, alerting for these things...
Regards,
Vitor
