What is the maximum allowable concentration of carbon monoxide in supplied air for asbestos workers?

The maximum allowable concentration of carbon monoxide in supplied air for asbestos workers is established to ensure the safety and health of individuals working in environments with potential hazards. A concentration of 10 parts per million (ppm) reflects a standard that balances effective air quality management while allowing workers to perform necessary tasks without excessive risk of exposure to toxic substances.

Maintaining carbon monoxide levels at or below this limit helps prevent health issues associated with inhalation of the gas, which can include headaches, dizziness, and, at higher levels, more severe neurological effects.

It's important to note that lower or higher thresholds would either provide inadequate protection, thereby exposing workers to unacceptable risk, or could result in unnecessary restrictions that hinder work efficiency. The determination of 10 ppm is a carefully considered guideline that reflects both industrial safety practices and public health recommendations.
