OCCUPATIONAL EXPOSURE LIMITS
TLV: (as Cr(VI), inhalable fraction): 0.0002 mg/m³, as TWA; 0.0005 mg/m³ as STEL; A1 (confirmed human carcinogen); (skin); (SEN). EU-OEL: (as Cr): 0.005 mg/m³ as TWA; (see Notes)

ENVIRONMENT
This substance may be hazardous to the environment. Special attention should be given to aquatic organisms. It is strongly advised not to let the chemical enter into the environment because it is persistent.

NOTES
Do NOT take working clothes home. Anyone who has shown symptoms of asthma due to this substance should avoid all further contact. The symptoms of asthma often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. EU-OEL limit value 0.010 mg/m³ until 17 January 2025. Limit value: 0.025 mg/m³ for welding or plasma cutting processes or similar work processes that generate fume until 17 January 2025.
