Hazards and Protection.

Storage　 　 　 　 Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling　 　 　 　 All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Protection　 　 　 　 Suitable protective clothing & self-contained resp protective apparatus should be available for use of those who may have to rescue persons overcome by fumes. Acrylic acid & derivatives.

Respirators　 　 　 　 Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Small spills/leaks　 　 　 　 (Non-Specific -- Methacrylic Acid) Do not touch spilled material; stop leak if you can do so without risk. For small spills, absorb with sand or other noncombustible absorbent material and place into containers for later disposal. For large spills, dike far ahead of spill for later disposal.

Stability　 　 　 　 No data.

Incompatibilities　 　 　 　 Reacts exothermically with water Incompatible with acids, strong oxidizing agents, alcohols, amines, and bases.

Fire.

Flash Point,°C　 　 　 　 84

Fire fighting　 　 　 　 (Non-Specific -- Methacrylic Acid) Keep unnecessary people away; isolate hazard area and deny entry. Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing.(Non-Specific -- Methacrylic Acid) This material may react violently with water. Small fires: dry chemical, carbon dioxide, water spray, or foam. Large fires: water spray, fog, or foam. Move container from fire area if you can do so without risk. Spray cooling water on containers that are exposed to flames until well after fire is out.

Health.

Exposure effects　 　 　 　

Ingestion　 　 　 　 Irritation or burns of the esophagus or gastrointestinal tract might follow ingestion.

Inhalation　 　 　 　 Respiratory tract irritation may occur.

Skin　 　 　 　 Dermal irritation and burns may occur. Sensitization might occur.

First aid　 　 　 　　　

Ingestion　 　 　 　 The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation. Activated charcoal activated charcoal binds most toxic agents and can decrease their systemic absorption if administered soon after ingestion. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.

Inhalation　 　 　 　 Move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with beta2 agonist and corticosteroid aerosols.

Skin　 　 　 　 Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. Treat dermal irritation or burns with standard topical therapy. Patients developing dermal hypersensitivity reactions may require treatment with systemic or topical corticosteroids or antihistamines.

Eyes　 　 　 　 Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
