TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE			In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		STRICT HYGIENE!
Inhalation	Sore throat. Cough. Nausea. Headache. Weakness. Shortness of breath. Laboured breathing. Symptoms may be delayed (see Notes).	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin		Protective gloves.
Eyes		Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Personal protection: self-contained breathing apparatus.

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA

Physical State; Appearance
COLOURLESS GAS.

Occupational exposure limits
TLV: 0.01 ppm; (Ceiling value); (ACGIH 2004).
MAK not established.

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

Effects of short-term exposure
The substance is irritating to the respiratory tract. Inhalation of this gas may cause lung oedema (see Notes). Exposure may result in death. The effects may be delayed. Medical observation is indicated.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 7°C Density: 1.6 g/l

NOTES

This substance is formed as a by-product in tetrafluoroethylene production and during thermal degradation of polytetrafluoroethylene (PTFE/Teflon(R)) at approximately 425°C.
The occupational exposure limit value should not be exceeded during any part of the working exposure.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential.
Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
Card has been partly updated in April 2005. See section Notes.
