av H Ingason · Citerat av 3 — The concentrations of oxygen, carbon dioxide, and carbon monoxide were measured in Telefax: +46 33 13 55 02. E-mail: 50. 60. CO. XCO, 5.1m [ppm].

Parts per million, or PPM, describes the diluted fluids of water or gas in the air in your home. Its measurement works like a percentage. The percentage is based on a scale of 100. If there was 1 percent of carbon monoxide gas in the air in your home, it would read as 10,000 parts per million.

200 Mild headache after 2-3 hours of exposure. 400 Headache and nausea after 1-2 hours of exposure. 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 : Workplace exposure limit (as 8-hour TWA) in most jurisdictions. >40,000 ppm Carbon monoxide poisoning typically occurs from breathing in carbon monoxide (CO) at excessive levels. Symptoms are often described as "flu-like" and commonly include headache, dizziness, weakness, vomiting, chest pain, and confusion.Large exposures can result in loss of consciousness, arrhythmias, seizures, or death.

12 rows Sidorenko et al. (1970) found an indoor level of carbon monoxide of 32.3 mg/m 3 (28 ppm) some two and a half hours after domestic gas combustion began, when there was no ventilation, but only 13.4 mg/m 3 (11.6 ppm) when ventilation was provided. 2010-08-12 I'm pretty sure it only actively shows the ppm in the air when it reaches 30 ppm, otherwise, you need to press the "peak" button which only shows levels 11 and greater.

While emissions controls on automobiles have reduced intentional CO poisonings, alternate sources may produce CO at levels of the same magnitude as vehicles manufactured prior to the use of catalytic converters. Those involved in the care of potentially suicidal individuals should be aware of this.
