TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 39°C explosive vapour/air mixtures may be formed.
Above 39°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID EXPOSURE OF (PREGNANT) WOMEN! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Confusion. Cough. Sore throat. Dizziness. Headache. Nausea. Unconsciousness. Vomiting. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! (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.
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. Diarrhoea. Nausea. Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.

SPILLAGE DISPOSAL

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. Attacks some forms of plastic, coatings.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm as TWA; (skin); BEI issued; (ACGIH 2003).
MAK: 5 ppm, 16 mg/m3; H;
Pregnancy risk group: B; Peak limitation category: II(8);
(DFG 2002).
OSHA PEL: TWA 25 ppm (80 mg/m3) skin
NIOSH REL: TWA 0.1 ppm (0.3 mg/m3) skin
NIOSH IDLH: 200 ppm See: 109864


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

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 and the respiratory tract . The substance may cause effects on the central nervous system , blood , bone marrow , kidneys and liver . Exposure at high levels may result in unconsciousness. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the blood and bone marrow , resulting in anaemia and lesions of blood cells . May cause toxicity to human reproduction or development.

ENVIRONMENTAL
DATA


N O T E S

Depending on the degree of exposure, periodic medical examination is indicated. The odour warning when the exposure limit value is exceeded is insufficient. Check for peroxides prior to distillation; eliminate if found.
