Scientists Claim High CO2 Levels Are Making People Dumber ...

Oct 27, 2015 · There are studies showing cognition decreases as CO2 levels increase, but there are also studies that show CO2 levels need to be extremely high to be harmful to human health. It’s also interesting that the U.S. Navy says average CO2 concentrations 3,500 parts per million (ppm) — levels nearly 10 times higher than what Harvard claims is safe.

healthcare - Do facemasks cause CO2 poisoning? - Skeptics ...

Jul 11, 2020 · The NIOSH indeed sets their 8-hour exposure to just 5,000 ppm, but this is quite conservative as they also set their STEL (15-minutes exposure) to 30,000 ppm (3%)--this is apparently based on submarine data. According to a 2005 review, the UK-equivalent authority had proposed only half the concentration for the latter (15,000 ppm for 15 minutes.)

Parts Per Million (ppm) Converter - Lenntech

Parts Per Million (ppm) Converter for Gases. This converter calculates the measured value in units of [ppm] into units of [mg/m 3] and visa versa. The unit ppm is used in several branches in different ways. The use of ppm therefore has to be specified in the input fields below, in the way it should convert the value with the proper unit.

IDPH Guidelines for Indoor Air Quality | IDPH

Other sources can include exhaust gas from kilns, internal combustion engines, dry ice, etc. Under these conditions, the Occupational Safety and Health Administration (OSHA) standard for carbon dioxide should be used. The OSHA standard is an eight-hour time-weighted average (TWA) of 5,000 ppm with a short-term 15-minute average limit of 30,000 ppm.

CO2 Sensors Products | CO2Meter.com

Indoor and outdoor air has between 400ppm and 2,000ppm CO2 by volume. This means that for projects from measuring indoor air quality to measuring atmospheric CO2, a 0-1% (0-10,000ppm) CO2 sensor is your best solution. For applications like CO2 alarms in restaurants, breweries, or around stored CO2 tanks, a 5% CO2 sensor is used.
