|ACRYLIC ACID||ICSC: 0688|
|CAS #: 79-10-7||Ethylenecarboxylic acid
| UN #: 2218 (stabilized)
| EINECS #: 201-177-9
|ACUTE HAZARDS||PREVENTION||FIRE FIGHTING|
|FIRE & EXPLOSION||Flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire. Above 48°C explosive vapour/air mixtures may be formed.||NO open flames, NO sparks and NO smoking. Above 48°C use a closed system, ventilation and explosion-proof electrical equipment. Vapours will be uninhibited and may polymerize in exhaust or ventilation facilities with risk of breakdown.||Use water spray, alcohol-resistant foam, powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|SYMPTOMS||ACUTE HAZARDS||FIRST AID|
|Inhalation||Cough. Sore throat. Burning sensation. Shortness of breath. Laboured breathing.||Use ventilation, local exhaust or breathing protection.||Fresh air, rest. Half-upright position. Refer for medical attention.|
|Skin||MAY BE ABSORBED! Redness. Pain. Serious skin burns.||Protective gloves. Protective clothing.||Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .|
|Eyes||Redness. Pain. Corneal damage.||Wear 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 refer for medical attention.|
|Ingestion||Burning sensation. Diarrhoea. Shock or collapse. Unconsciousness.||Do not eat, drink, or smoke during work.||Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.|
|SPILLAGE DISPOSAL||CLASSIFICATION & LABELLING|
|Evacuate danger area! Consult an expert! Personal protection: complete protective clothing including self-contained breathing apparatus. Ventilation. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.||

|The substance is harmful to aquatic organisms.|
|Acrylic acid is commercially available in stabilized form by addition of polymerization inhibitors (see Chemical Dangers).
Acrylic acid solidifies below 14 °C leading to a localized depletion of stabilizer. Follow the manufacturer's instructions regarding thawing.
An added stabilizer or inhibitor can influence the toxicological properties of this substance; consult an expert.
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
Someone who has shown signs of sensitivity to the substance should avoid any further contact with this substance or any other acrylates.
