POTENTIAL HEALTH EFFECTS
Effects of Overexposure:
Eye Contact
Eye contact with the rapidly evaporation liquid may cause frostbite.
Skin Contact
Skin contact with the rapidly evaporation liquid may cause frostbite. Frostbite effects are a change in color of the skin to
gray or white, followed by blistering.
Inhalation
Vapor is heavier than air and can cause suffocation by reducing oxygen available for breathing. Inhalation of high vapor
concentration may cause dizziness, disorientation, incoordination, narcosis, nausea or vomiting, leading to unconsciousness,
cardiac irregularities, or death.
