Following Exposure: Inhalation of vapor irritates nose and throat. Contact with eyes causes intense
irritation and tears. Contact of liquid with skin causes severe blistering and dermatitis. Ingestion causes
severe irritation of mouth and stomach; General TreatmentforExposure: INHALATION: remove from
exposure; provide low-pressure oxygen if required; keep under observation until edema is ruled out.
