Exposure control/personal protection occupational exposure limits China MAC (mg/m3): 1 [dust], 0.2 [smoke] TLVTN: smoke 0.2mg/m3, dust and mist 1mg/m3 (copper meter). TLVWN: No standard has been established Monitoring methods: flame atomic absorption spectrometry; 5-Br-PADAP colorimetry; catalytic polarography Engineering control: closed operation, local exhaust. Respiratory system protection: When the dust concentration in the air exceeds the standard, a self-priming filter dust mask must be worn. During emergency rescue or evacuation, air respirators should be worn. Eye protection: Wear chemical safety glasses. Body protection: Wear anti-toxic agent overalls. Hand protection: Wear rubber gloves. Other protection: Change and wash work clothes in time. Pay attention to personal hygiene.
