Regulatory Frameworks

• In the U.S., chlorine trifluoride is regulated under the Occupational Safety and Health Administration (OSHA), which enforces a ceiling exposure limit of 0.1 ppm. The National Institute for Occupational Safety and Health (NIOSH) classifies it as immediately dangerous to life or health (IDLH) at 20 ppm.
• In the European Union, Chlorine trifluoride is classified as a hazardous substance under the European Union’s Classification, Labelling and Packaging (CLP) Regulation and is also subject to the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Regulation. Occupational exposure is limited to a ceiling of 0.1 ppm under the Directive 2000/39/EC. German regulations, via the German Hazardous Substances Committee (AGS), align with EU rules, mandating process containment, ventilation, and emergency response systems for safe handling.
• Japan sets the occupational exposure ceiling limit for chlorine trifluoride at 0.1 ppm through the Japan Society for Occupational Health (JSOH). Industrial users must install leak detection systems, gas scrubbers, and maintain controlled environments. Under Japan’s Industrial Safety and Health Act (ISHA), employers must regularly monitor short-term exposure levels.
• South Korea regulates chlorine trifluoride through the Ministry of Employment and Labor under the Occupational Safety and Health Act (OSHA Korea), applying a ceiling exposure limit similar to global norms (0.1 ppm). The substance is classified as a hazardous material, requiring closed processing systems, gas detection equipment, and emergency planning. Korea follows the Act on Registration and Evaluation of Chemicals (K-REACH), and mirrors many aspects of the EU’s REACH framework.
