Maybe you're joking, but the bbq is acute exposure and the article focuses on chronic exposure. As for heating, if your heater puts your indoor CO2 above 0.5% then you are above the NIOSH / OSHA limits and should get it fixed. Article says measurements inside masks read 1 to 3%. Incidentally, bad indoor ventilation is an increasingly recognized health risk.
- orwin 4y agoWhat, up to 3%? i missed that, but if true, that's a huge issue. Some woodworkers use way more airtight masks 4 to 8 hours a day, 5 days a week. If true, those concentration levels are criminal and I expect a lot of construction companies (and sawmills, and papermills) to get sued for damage.
- foobarbecue 4y agoYou missed it? See the first sentence of the results section, table 1, and ... the rest of the paper. I looked into some of the refs in table 1 and it seems they are being misrepresented, mostly because Kisielinski et al are acting like this is the concentration during inhalation when in the 2 papers I looked at it was average over time. Since exhaled breath has several percent, I think you really need to be able to resolve concentration over time and look at the inhale, otherwise the data is useless.
