TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with oxidizing agents. NO open flames.  Use water spray, powder, foam, carbon dioxide. 
EXPLOSION Above 77°C explosive vapour/air mixtures may be formed.  Above 77°C use a closed system and ventilation. Prevent build-up of electrostatic charges (e.g., by grounding).  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE      
Inhalation Cough. Dizziness. Headache. Nausea. Vomiting. Weakness.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Redness. Pain.  Protective gloves.  Rinse skin with plenty of water or shower. Remove contaminated clothes. 
Eyes Pain. Redness. Blurred vision.  Wear safety spectacles.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Abdominal pain. See Inhalation.  Do not eat, drink, or smoke during work.  Do NOT induce vomiting. Give one or two glasses of water to drink. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit. Do NOT let this chemical enter the environment. Ventilation. Collect leaking and spilled liquid in covered containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
As a result of flow, agitation, etc., electrostatic charges can be generated. 

Chemical dangers
The substance can form explosive peroxides. Decomposes on heating. This produces irritating fumes. Reacts vigorously with oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. 

Effects of short-term exposure
The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the kidneys.
