TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 35°C explosive vapour/air mixtures may be formed.
Above 35°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

•INHALATION Sore throat. Cough. Burning sensation. Shortness of breath.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer for medical attention.
•SKIN MAY BE ABSORBED! Redness. Pain. Blisters. See Notes.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Lachrymation. Pain. Burns
Face shield, or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION Burning sensation in the throat and chest.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention if you feel unwell

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

Remove all ignition sources. Evacuate danger area! Consult an expert! Personal protection: filter respirator for organic gases and vapours. Ventilation. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place.
Store only if stabilized. Fireproof. Separated from strong oxidants, food and feedstuffs . Keep in the dark.
Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT ODOUR. TURNS DARK ON EXPOSURE TO LIGHT

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance will polymerize slowly under the influence of light with fire or explosion hazard. The substance decomposes on heating and on burning.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 1 ppm (Ceiling value) (skin) (ACGIH 2006).
MAK not established.


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 very quickly on evaporation of this substance at 20°C.

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

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

ENVIRONMENTAL
DATA


N O T E S

After contact with liquid blister formation may be delayed until several hours have passed. Explosive limits are unknown in literature, although the substance is combustible and has a flash point < 55°C. The occupational exposure limit value should not be exceeded during any part of the working exposure. The odour warning when the exposure limit value is exceeded is insufficient. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
