- I haven't visited a biohacker lab, so I can't say much about how they do things. I have met a couple people involved with +BioCurious
and they seemed reasonable and responsible, but that doesn't mean everyone is.
Biocurious does at least have safety training, rules, and a safety committee that reviews projects, and they say the lab is Biosafety Level – 1 (BSL-1), similar to a high school biology lab. There is a little more info in the Safety section of their FAQ page at http://biocurious.org/faq/
You can also send them questions at firstname.lastname@example.org .
