EYES: Liquid contact can cause irritation, which may be severe.
SKIN: Prolonged or repeated contact can result in defatting and drying of the skin which may result in
skin irritation and dermatitis (rash).

unconsciousness, and possibly death with longer exposure. Keep people away from such vapors
without self-contained breathing apparatus.
