EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion. 

Effects of short-term exposure
The substance is irritating to the respiratory tract. 

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. The substance may have effects on the kidneys. Repeated or prolonged inhalation may cause nasal ulceration. This may result in perforation of the nasal septum. This substance is carcinogenic to humans.

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.
