OSHA regulates the level of chlorine dioxide in workplace air for safety. OSHA has set a Permissible Exposure Limit (PEL) for chlorine dioxide at 0.1 parts per million (ppm), or 0.3 milligrams (mg) per cubic meters (m3) for workers using chlorine dioxide for general industrial purposes.
“Chlorine dioxide may be safely used in food in accordance with the prescribed conditions noted in Title 21, Volume 3, Sec 173.3”.
“Chlorine dioxide and chlorite are strong oxidizing agents used as drinking water disinfectants and to bleach textile and wood pulp for paper manufacturing. In general, human ingestion studies have found no adverse effects in adults and neonates living in areas with chlorine dioxide-disinfected water”.
The transportation of chlorine dioxide (Dept. of Transportation Reference #UN1760) should be in accordance with all applicable Federal, State, and local rules, regulations and requirements.
