TYPES OF HAZARD
|ACUTE HAZARDS / SYMPTOMS||PREVENTION||FIRST AID / FIRE-FIGHTING|
|FIRE||Flammable. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.||NO open flames, NO sparks and NO smoking.||Use water spray, alcohol-resistant foam, powder, carbon dioxide.|
|EXPLOSION||Above 48°C explosive vapour/air mixtures may be formed.||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.||In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.|
|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.|

|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.
