TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 51°C explosive vapour/air mixtures may be formed.
Above 51°C use a closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!

•INHALATION Cough. Shortness of breath.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN MAY BE ABSORBED! Redness.
Protective gloves. Protective clothing.
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 Burning sensation.
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


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

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK: 5 ppm, 28 mg/m3; skin absorption (H);
Peak limitation category: II(8); Pregnancy risk group: B;
(DFG 2004).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, by ingestion and through the skin.

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is mildly irritating to the eyes , the skin and the respiratory tract .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxicity to human reproduction or development.
