Ceramic transmitting tubes and semiconductors also use BeO. Those warning labels don\'t always follow equipment through production and testing. A test tech on the GRC106 ended up in the hospital when one of the Eimac finals was damaged during shipping from Mexico to Cincinnati. They were just tossing the paperwork since they couldn\'t read English. Luckily for that tech, the man at the next bench saw him with the damaged tube. He wrapped a plastic bag over the tech\'s hands and the tube. He had someone call for an a.mbulsnce as he hurried him running to a sink to wet down the dust. He saved his coworker\'s life. After that, the paperwork was wired to each subassembly that contained BeO. YOLO.
I can believe that BeO must be pretty nasty because they used to give
warnings about it, even back in the time when warnings were reserved for
actually very dangerous things. Nowadays due to every harmless thing
being plastered with warnings, they have become rather devalued and it
is much harder to identify what really is dangerous.
yup. Starbuck Coffee in CA post the prop 65 warnings about dangerous
chemicals (yes, coffee) in their stores. They have lots of free time in CA
it seems.
Hmm, what kind of warning would CA put on a magnetron coupled to a
waveguide full of pressurized SF6? That was pumping 5MW pulses to a
big dish...
Also, I\'ll put a switch on the primary, but I can\'t guarantee that
switch will always get turned off after the power switch on the leaf
blower is shut off. My wife will be the user, I can put a light in the
circuit, she would be certain to turn off an unneeded light.
