What harm does exposure to gallium arsenide and related substances do to the health during the production of gallium arsenide solar cells? What is the protection in its production and its effect?
I don't know much about solar cells, but gallium arsenide is not toxic to gallium arsenide itself. Gallium arsenide will decompose above 500 degrees (this value is not exact) to produce arsenic vapor, which can easily react with oxygen to produce arsenic oxide (that is, arsenic), but solar cells do not seem to reach such a temperature, so there should be no need to worry about poisoning. As for working for two days and taking two days off, it is definitely not caused by injury, but by discontinuous production.
