What is the maximum CO2 content allowed in air delivered to working places?

The maximum allowable carbon dioxide (CO2) content in air delivered to working places is 0.5%. This standard is established to ensure safety and the health of workers. Elevated levels of CO2 can lead to adverse health effects, including impaired cognitive function, headaches, dizziness, and in extreme cases, loss of consciousness.

A concentration of 0.5% is a guideline that helps to maintain air quality, ensuring it remains at a safe level for breathing and overall well-being. Regulations often stipulate this level to prevent any negative impacts on productivity and to safeguard against long-term exposure risks.

Other listed levels either exceed or do not meet the established safety standards for working environments, which underscores the importance of maintaining adequate air quality in any work setting.
