|OCCUPATIONAL EXPOSURE LIMITS|
TLV: 0.01 mg/m3, as TWA; A1 (confirmed human carcinogen); BEI issued.
MAK: skin absorption (H); carcinogen category: 1; germ cell mutagen group: 3A.
EU-OEL: (inhalable fraction): 0.01 mg/m3 as TWA; (see Notes)
|The substance is very toxic to aquatic organisms. This substance may be hazardous to the environment. Special attention should be given to birds, fish and mammals. It is strongly advised not to let the chemical enter into the environment.|
|Do NOT take working clothes home.
Physical properties depend on crystalline form of the substance.
The symptoms of acute poisoning appear ½ to 1 hour after the exposure but may be delayed many hours.
Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available.
The symptoms of lung oedema 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.
Refer for medical attention if breathing difficulties and/or fever develop.
Depending on the degree of exposure, periodic medical examination is suggested.
The recommendations on this Card also apply to inorganic trivalent arsenic compounds (arsenites).
For the copper smelting sector, the EU OEL value shall apply from 11 July 2023.
