How Much Co2 In Air Is Dangerous: Understanding The Threshold

Determining the acceptable indoor levels of carbon dioxide (CO2) is a critical aspect of ensuring good indoor air quality. To address this concern, experts often turn to established guidelines rooted in ventilation rates. One of the most widely recognized authorities in this domain is the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). According to ASHRAE, maintaining indoor CO2 levels below 1,000 parts per million (ppm) is recommended as a guideline for acceptable indoor air quality in buildings. This guideline, set as of August 24, 2023, is vital for assessing and maintaining a healthy and comfortable indoor environment.

“What are the consequences of having a CO2 level exceeding 100? When experiencing chronic hypercapnia, individuals may initially experience non-specific symptoms such as fatigue, headaches, and breathlessness. Over time, these mild symptoms can progress to more severe neurological issues, including confusion. On the other hand, acute hypercapnia, characterized by a rapid increase in CO2 levels, can lead to the abrupt onset of neurological symptoms, severe headaches, and pronounced breathlessness. These effects can have a significant impact on an individual’s well-being. [Date: March 9, 2023].”
