We all know that Carbon Monoxide (CO) exposure needs to be taken seriously as it can have alarming effects on human health.
Let’s get started!
Inhaling high levels of CO causes oxygen starvation which can affect vital organs like the heart, brain, and nervous system. CO is extremely dangerous because we cannot detect the presence or level of the gas as it has no taste or smell and cannot be seen. People suffering from heart disease are even more vulnerable, as even short-term exposure to elevated CO levels may result in critical health issues.
Initial symptoms of CO poisoning may include flu-like symptoms such as headache, dizziness, weakness, nausea, and fatigue. In case of prolonged or high exposure, this may lead to vomiting, loss of consciousness, and collapse. Furthermore, it may lead to a coma or death if high exposures continue.
Let’s break down the effects of CO poisoning at the various parts-per-million (ppm) levels:
PPM RANGE | EFFECTS |
---|---|
0 to 1 ppm | Normal background levels |
9 ppm | ASHRAE Standard 62-1989 for living areas |
35 ppm | The average exposure level per U.S. OSHA workplace standards |
50 ppm | OSHA enclosed space 8-hour average level* |
100 ppm | OSHA exposure limit* |
200 ppm | Mild headache, fatigue, nausea, and dizziness |
400 ppm | Headache occurs in 2.5 to 3.5 hours |
800 ppm | Dizziness, nausea and convulsions, Death within 2 to 3 hours |
*U.S. Department of Labor, Occupational Safety & Health Administration (OSHA) Regulation 1917.24: The CO content in any enclosed space shall be maintained at not more than 50 ppm (0.005%). Remove employees from enclosed space if the CO concentration exceeds 100 ppm (0.01%).
Steps to ensuring a safe environment:
4 reasons why CO monitoring is important:
Carbon Monoxide monitors have been the preferred solution for ambient air monitoring as they yield more accurate CO concentrations and are inexpensive compared to other solutions. Perform safety checks on gas-powered machinery, with a Carbon Monoxide monitor that sounds an alarm to let you know when exposure levels are too high.
