|OCCUPATIONAL EXPOSURE LIMITS|
|The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.|
|The EU classification refers to a group of substances known as quaternary ammonium compounds, benzyl C8-18-alkyldimethyl chlorides.
Benzalkonium chloride itself is a mixture of very similar substances with different chain length and molecular mass.
Other CAS RN: 8001-54-5; Other UN numbers are possible, depending on manufacturers´classifications.
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.
This substance is usually commercially available as a solution.
Strong solutions (>10%) are corrosive.
