Your water is safe, how about your air?

What are safe levels of CO and CO2 in rooms?

CO2

250-350ppm         Normal background concentration in outdoor ambient air
350-1,000ppm      Concentrations typical of occupied indoor spaces with good air exchange
1,000-2,000ppm   Complaints of drowsiness and poor air.
2,000-5,000 ppm  Headaches, sleepiness and stagnant, stale, stuffy air. Poor concentration, loss of attention, increased heart rate and slight nausea may also be present.
5,000 ppm             Workplace exposure limit (as 8-hour TWA) in most jurisdictions.
>40,000 ppm         Exposure may lead to serious oxygen deprivation resulting in permanent brain damage, coma, even death


CO

9 ppm          CO Max prolonged exposure (ASHRAE standard)
35 ppm        CO Max exposure for 8 hour work day (OSHA)
800 ppm      CO Death within 2 to 3 hours
12,800 ppm CO Death within 1 to 3 minutes

Volatile Organic Compounds (VOC)
Chemicals that emit gas are called VOC. Another common term, Total VOC (TVOC) is a combined variety of organic chemicals that emit gas. They are measured in micrograms per meter cubed (µg/m3) of air, parts per million (ppm), or parts per billion (ppb). Most buildings will have TVOC levels ranging from 100-500 µg/m3 (Aerias). Table 1, below, is used as a guide to compare TVOC results with its symptoms.


Table 1: TVOC and Symptoms

TVOCSymptoms
< 200 µg/m3No irritation or discomfort expected
200 – 3,000 µg/m3Irritation and discomfort may be possible
3,000 – 25,000 µg/m3Discomfort expected and headache possible
> 25,000 µg/m3Toxic range where other neurotoxic effects may occur


Source from Aerias

Concentrations of many VOC are consistently (up to ten times) higher indoors than outdoors (US Environmental Protection Agency, 2010). Therefore, some VOC are regulated due to its short and long term affects on the health of humans. For example, the most common VOC is formaldehyde. On average, formaldehyde levels measured over a day in Canadian homes were 20-40 μg/m3 (16-32.5 ppb). Daily levels as high as 95 μg/m3 (77 ppb), however, have been recorded (Health Canada, 2009b). This chemical is strictly regulated by the Occupational Safety & Health Administration (OSHA) as it has been known to cause cancer. Table 2, below, lists a few common VOC along with the recommended exposure limit (REL) of the National Institute for Occupational Safety and Health (NIOSH), permissible exposure limit (PEL) of OSHA, identified symptoms if exposed to the chemical and some examples of products that contain the chemical...
