Vapor is heavier than air and can cause suffocation by reducing the available oxygen for breathing.
Breathing high concentrations of vapor may cause light-headedness, giddiness, shortness of breath, confusion, and may lead to narcosis, cardiac irregularities, or unconsciousness. Inhalation of high concentrations in a closely confined area may be fatal. May have adverse effects on liver, lung and kidney in high doses. Liquid contact will irritate eyes. Expected to be an irritant, not corrosive.
