|The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment.|
|Do NOT take working clothes home.
Rinse contaminated clothing with plenty of water because of fire hazard.
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.
The recommendations on this Card also apply to sodium chromate tetrahydrate (CAS No. 10034-82-9).
