Potential Health Effects
Eye: Irritant. In case of exposure to eye, flush with copious amounts of water
for at least 15 minutes, keeping the eyelid open with fingers. Seek medical attention.
Skin: May cause sensitization. Readily absorbed through skin. In case of skin
contact, flush with large amounts of water for at least 15 minutes. Remove contaminated
clothing and shoes. Seek medical attention.
Ingestion: If conscious, wash out mouth with water. Seek medical attention.
Inhalation: If inhaled, move to fresh air. If breathing becomes difficult,
seek medical attention.
Chronic: Laboratory experiments have resulted in mutagenic effects.
Auto Ignition Temp: 80° C
General Information:
