Ubuthi be-LD50 ngomlomo ngogwaja: 1320 mg / kg
S26: Uma uthintana ngamehlo, hlambulula ngokushesha ngamanzi amaningi futhi ufune izeluleko zezokwelashwa.
I-S36 / 37/39: Gqoka izingubo ezifanele zokuvikela, amagilavu kanye nokuvikelwa kwamehlo.
I-S45: Uma kwenzeka ingozi noma uzizwa ungaliwe, funa izeluleko zezokwelashwa ngokushesha (Khombisa iLeable lapho kungenzeka khona).
Gcina endaweni epholile. Gcina i-airtight yesitsha bese ugcina endaweni eyomile, enomoya.
