|PHYSICAL & CHEMICAL INFORMATION|
Physical State; Appearance
Formula: C12H14Cl2N2 / CH3(C5H4N)2CH3・2Cl
|EXPOSURE & HEALTH EFFECTS|
Routes of exposure
Effects of short-term exposure
Effects of long-term or repeated exposure
|OCCUPATIONAL EXPOSURE LIMITS|
|TLV: (as the cation): 0.05 mg/m3, as TWA; (skin); A4 (not classifiable as a human carcinogen)|
|The substance is very toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal.|
|The toxicological information is the same for paraquat (CAS 4685-14-7).
Depending on the degree of exposure, periodic medical examination is suggested.
The symptoms of lung fibrosis (shortness of breath, laboured breathing) do not become manifest until several days.
Rest and medical observation are therefore essential.
Do NOT take working clothes home.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
If the substance is formulated with solvent(s) also consult the card(s) (ICSC) of the solvent(s).
