4) exposure concentration value How is the exposure concentration determined? Measured Estimated. Please indicate how: Don't know. If measured, please specify the number of samples and how the exposure concentration given below was derived. Air exposure concentration and unit: B9) Risk Management Measures (RMMs) are currently in place to control exposure in Group 2? Measures that seek to Answer 1. Reduce the number of workers exposed (fewer, rotate, etc.) Rotation of workers Substitution of workers by automatization/ robotic operators please specify: 2. Reduce the concentration at the workplace General ventilation Yes No Local exhaust ventilation (LEV) Fume hoods Extraction or grinding tables Fume extractor guns spot extraction) Low-vacuum spot extraction High-vacuum spot extraction Mobile extraction and filter units Other, please specify: Modification of working processes (e.g. use of secondary shield gas containing reducing agents in gas metal arc welding) may reduce Cr(VI) exposure) Yes No If yes, please specify: Substitution of working processes (For some materials, processes generating less fumes and/or less Cr(IV) may be available) Yes No If yes, please specify: Substitution of materials (e.g. use of electrodes generating less and/or less Cr(IV)) Yes No If yes, please specify: Detect unusual exposures Yes No If yes, please specify: Cleaning of base metal surfaces of any coating or paint Yes No Not relevant 3. Reduce worker exposure: Information of workers on working with hazardous materials Yes No If yes, please specify: Personal protection equipment (PPE) to reduce inhalation exposure to workers Fresh-air supplying masks Simple filter masks Filter with battery-powered (turbo-unit) please specify: 4. Other measures, please specify Group 3
3. Reduce worker exposure: Information of workers on working with hazardous materials Yes No If yes, please specify: Personal protection equipment (PPE) to reduce inhalation exposure to workers Fresh-air supplying masks Simple filter Filter masks with battery-powered (turbo-unit) Other, please specify: 4. Other measures, please specify C) RMMs required to achieve OELs for Cr(VI) from welding, plasma cutting and similar work processes that generate fumes This section enquires about the measures that will have to be put in place to comply with the new OEL of 5 µg/m3 for ‘chromium (VI) compounds in welding or plasma cutting processes or similar work processes that generate fume’ which will enter into force 5 years after the transposition date of the compromise recently reached by Council and the European Parliament on the Commission proposal COM(2016)248 final. C1) Which Risk Management Measures (RMMs) (if any) will you have to implement to achieve an OEL of 25 µg/m3?
