Section 2
SECTION 2: Hazards identification
OSHA EMERGENCY OVERVIEW CAUTION! Liquid and gas under pressure. Can cause rapid suffocation. May cause frostbite. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers. Under ambient conditions, this is a colorless, odorless gas at normal temperature and pressure. OSHA REGULATORY STATUS: This material is considered hazardous by the OSHA Hazard Communications Standard (29 CFR 1910.1200).
Potential health effects
Effects of a Single (Acute) Overexposure Inhalation. Asphyxiant. High concentrations may cause dizziness, nausea, vomiting, disorientation, confusion, incoordination, and narcosis. Very high concentrations may cause suffocation. Lack of oxygen can kill. Skin Contact. Liquid hexafluoroethane may cause frostbite; harmful amounts may be absorbed if skin contact is prolonged or widespread. Swallowing. An unlikely route of exposure, but frostbite of the lips and mouth may result from contact with the liquid. Eye Contact. Liquid may cause severe corneal injury. Effects of Repeated (Chronic) Overexposure. No harm expected. Copyright © 1979, 1985, 1988, 1992, 1997, 2003, 2006, 2009, Praxair Technology, Inc. Page 1 of 9 All rights reserved. A vertical line in the left margin indicates revised or new material. Other Effects of Overexposure. At very high concentrations, hexafluoroethane may produce cardiac arrhythmias or arrest due to sensitization of the heart to adrenaline and noradrenalin. Exposure to fluorocarbon thermal decomposition products may produce flu-like symptoms including chills, fever, weakness, muscular aches, headache, chest discomfort, sore throat, and dry cough. Complete recovery usually occurs within 24 hours after exposure.
Medical Conditions Generally Aggravated by Exposure
Overexposure. The toxicology and the physical and chemical properties of hexafluoroethane suggest that overexposure is unlikely to aggravate existing medical conditions. CARCINOGENICITY: Hexafluoroethane is not listed by NTP, OSHA, or IARC.
Environmental effects
None known. For further information, see section 12, Ecological Information.
