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 60°C explosive vapour/air mixtures may be formed.
Above 60°C closed system, ventilation.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Dizziness. Drowsiness. Headache. Nausea. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! Dry skin. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Blurred vision.
Safety goggles 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. Diarrhoea. Nausea. Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give one or two glasses of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water. Remove all ignition sources. Personal protection: filter respirator for organic gases and vapours.
Separated from strong oxidants, food and feedstuffs . Cool. Keep in the dark.
Airtight. Do not transport with food and feedstuffs.

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

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance can form explosive peroxides. Reacts with strong oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV:
(as TWA)
20 ppm; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: 10 ppm, 49 mg/m3;
Peak limitation category: I(2);
skin absorption (H);
Carcinogen category: 4; Pregnancy risk group: C;
(DFG 2006).
OSHA PEL†: TWA 50 ppm (240 mg/m3) skin
NIOSH REL: TWA 5 ppm (24 mg/m3) skin
NIOSH IDLH: 700 ppm See: 111762


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

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . central nervous system , blood , kidneys and liver .

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