Next in the "Can Plasma?" series: can plasma be used safely around people? Short answer: it depends on your definition of "safely," "used," and "people." Let me walk you through what that actually means.

⏱️ Chapters

00:00 The question: can plasma be used safely around people?

00:31 Why the question hinges on three definitions

00:41 The welding torch test: would you hand one to a 7-year-old?

01:16 The unplugged torch at show-and-tell — context is everything

01:35 Hazard #1: Ozone (and why it disappears in a sunny field but not in a hospital)

02:14 FDA limits on human ozone exposure

02:33 Why hospital patient treatment is hard — but hospital laundry might work

02:56 Hazard #2: Ultraviolet radiation (why welders wear masks)

03:17 Hazard #3: High voltage

03:23 Why I'm talking about this — trade-show questions and "can I buy one for home?"

03:46 The welding analogy: trained engineers are MORE afraid, not less

04:17 The helium plasma jet example — even "gentle" plasmas have safety considerations

04:59 OSHA and FDA ozone limits depend on jet size

05:15 What "safely" really means: which plasma, which application, which people?

05:55 The same logic applies to lasers, pharmaceuticals, and ethanol

06:24 Wrap-up — drop your "Can Plasma?" questions below

If you work in plasma applications, medical devices, industrial safety, or you're just curious whether you can buy one and play with it at home — this one's for you.
