TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive. Above 86C explosive vapour/air mixtures may be formed.
Above 86C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Cough. Headache. Laboured breathing. Nausea. Sore throat. Unconsciousness. Vomiting.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Roughness. Skin burns. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain. Severe deep burns.
Safety goggles, face shield or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal pain. Burning sensation. Dizziness. Dullness. Headache. Shock or collapse. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Rest. Refer for medical attention.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and irritating fumes. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm as TWA; (skin); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 3A; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is severely irritating to the eyes, the skin, the respiratory tract. Corrosive on ingestion. The substance may cause effects on the central nervous system. Exposure may result in unconsciousness. The effects may be delayed.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Lungs may be affected by repeated or prolonged exposure to the vapour. The substance may have effects on the liver, kidneys and pancreas.
