Sulfur dioxide (SO2) does not have a specific IDLH value. This is because the IDLH value is dependent on the specific situation and the individual's sensitivity to the substance.
However, the OSHA Permissible Exposure Limit (PEL) for sulfur dioxide is 5 ppm (13 mg/m3) as an 8-hour time-weighted average.
Exposure to high concentrations of sulfur dioxide can cause:
* Irritation of the eyes, nose, and throat
* Difficulty breathing
* Coughing
* Wheezing
* Chest tightness
* Pulmonary edema (fluid in the lungs)
If you suspect sulfur dioxide exposure, it is important to:
* Move to fresh air immediately.
* Seek medical attention.
Note: The IDLH value for a substance may vary depending on the source. It is always best to consult with a safety professional or refer to the relevant safety data sheet (SDS) for specific information.
