TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible.	NO open flames.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 78°C explosive vapour/air mixtures may be formed.	Above 78°C use a closed system, ventilation.

EXPOSURE
•INHALATION		Ventilation. Local exhaust.	Fresh air, rest.
•SKIN	Dry skin.	Protective gloves.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES	Redness. Pain.	Safety spectacles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance can presumably form explosive peroxides. Reacts with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK:
Pregnancy risk group: C;
(DFG 2003).
EU OEL: 10 ppm, 67.5 mg/m³ as TWA; 15 ppm, 101.2 mg/m³ as STEL (EU 2006).

ROUTES OF EXPOSURE:

INHALATION RISK:
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
