Which gas has a TLV of 50 ppm, a ceiling limit of 200 ppm, and an IDLH of 1500 ppm?

The gas that has a threshold limit value (TLV) of 50 ppm, a ceiling limit of 200 ppm, and an immediately dangerous to life or health (IDLH) concentration of 1500 ppm is indeed Carbon Monoxide.

Understanding these values is crucial when considering the safety and health risks associated with different gases in mining environments. The TLV of 50 ppm indicates the maximum concentration of Carbon Monoxide that workers are permitted to be exposed to over an 8-hour work shift; this is based on protecting health over the long term. The ceiling limit of 200 ppm signifies the highest concentration that must not be exceeded at any time during exposure, underscoring the immediate risks associated with higher concentrations of this gas. The IDLH threshold of 1500 ppm represents a concentration that would pose an immediate threat to life and would prevent escape from a hazardous environment.

Carbon Monoxide is particularly concerning because it is a colorless, odorless gas that can lead to serious health effects, including asphyxiation, even with short exposures. Understanding its TLV, ceiling limit, and IDLH value is vital for anyone working in mines where this gas may be present, ensuring proper monitoring and safety precautions can be implemented to protect workers
