Introducing a case of organic solvent poisoning during non-regular operations in metal cleaning equipment.
While a basket was rotating in the washing tank of the cleaning device, it came loose, causing the products being cleaned to scatter inside the tank. A worker entered the cleaning device to pick up the scattered products. However, since they entered while there was still about half of the cleaning solution remaining, they inhaled the vapor of dichloromethane contained in the cleaning solution and were exposed. The worker lost consciousness after inhaling the vapor of the cleaning solution and was found in a state caught on a hanger inside the cleaning device by the cleaning operator, who rescued them. They were diagnosed with dichloromethane poisoning by a doctor and took 15 days off work. [Recommendations] ■ Measuring gas concentration is effective for confirming adequate ventilation. ■ Using a personal PID monitor for chemical risk assessment is recommended. *For more details, please refer to the PDF document or feel free to contact us.
