What is the IDLH level for Sulfur Dioxide?

The correct identification of the IDLH (Immediately Dangerous to Life or Health) level for Sulfur Dioxide is crucial for ensuring safety in environments where exposure to this gas may occur. The IDLH for Sulfur Dioxide is established at 100 ppm, which indicates that concentrations at or above this level pose a significant risk to health and require immediate protective measures.

Understanding IDLH values is essential for workers in industries such as mining or chemical handling, where they may encounter potentially harmful gases. At 100 ppm, Sulfur Dioxide can cause serious respiratory issues and other health effects, making it vital for mine foremen to recognize this threshold so that they can implement appropriate safety protocols, such as ventilation, personal protective equipment, or evacuation procedures.

The other values listed do not accurately represent the IDLH level for Sulfur Dioxide according to OSHA and NIOSH standards, which further underscores the importance of this specific threshold in occupational safety settings.
