Halocarbon-14

SECTION 2: Hazards identification

OSHA EMERGENCY OVERVIEW CAUTION! High-pressure gas. Can cause rapid suffocation. May cause dizziness and drowsiness. Self-contained breathing apparatus may be required by rescue workers. Under ambient conditions, this is a colorless odorless gas. 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 can cause dizziness, nausea, vomiting, disorientation, confusion, incoordination, and narcosis. Very high concentrations may cause suffocation. Lack of oxygen can kill. Skin Contact. No harm expected. Swallowing. An unlikely route of exposure, this product is a gas at normal temperature and pressure. Eye Contact. No harm expected. Effects of Repeated (Chronic) Overexposure. No harm expected. Other Effects of Overexposure. At high concentrations, tetrafluoromethane 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 tetrafluoromethane suggest that overexposure is unlikely to aggravate existing medical conditions. CARCINOGENICITY: Tetrafluoromethane is not listed by NTP, OSHA, or IARC.
