TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking. NO contact with strong oxidants.
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE


•INHALATION Cough. Headache. Fatigue. Drowsiness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest.
•SKIN Dry skin.
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
•EYES Redness. Pain. Burning.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Burning sensation. Headache. Confusion. Dizziness. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Wash away remainder with plenty of water.
Fireproof. Separated from strong oxidants.

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

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
Reacts slowly with calcium hypochlorite, silver oxide and ammonia, causing fire and explosion hazard. Reacts violently with strong oxidants such as nitric acid, silver nitrate, mercuric nitrate or magnesium perchlorate, causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1000 ppm as TWA; A4 (not classifiable as a human carcinogen); (ACGIH 2004).
MAK: 500 ppm, 960 mg/m3;
Peak limitation category: II(2); Carcinogen category: 5; Pregnancy risk group: C; Germ cell mutagen group: 5;
(DFG 2004).
OSHA PEL: TWA 1000 ppm (1900 mg/m3)
NIOSH REL: TWA 1000 ppm (1900 mg/m3)
NIOSH IDLH: 3300 ppm 10%LEL See: 64175


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour 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 irritates the eyes. Inhalation of high concentration of vapour may cause irritation of the eyes and respiratory tract. The substance may cause effects on the central nervous system .

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin. The substance may have effects on the upper respiratory tract and central nervous system , resulting in irritation, headache, fatigue and lack of concentration. See Notes.
