FAQ: Safety & Handling

What are the primary hazards of High purity Methacrylic Acid 99% min CAS 79-41-4?

It is a corrosive liquid that can cause severe skin burns and eye damage. It is also a combustible liquid with a flash point of 77°C. Inhalation of vapors may cause respiratory irritation.

Is it dangerous to store?

Yes, if not stored correctly. High purity Methacrylic Acid 99% min CAS 79-41-4 must be stored in a cool, ventilated warehouse (ideally below 25°C). It is sensitive to temperature; if it freezes (melting point 14°C), it must be thawed carefully to avoid localized overheating, which can trigger violent polymerization.

What are the exposure limits and handling protocols?

Operators should use acid-resistant gloves, safety goggles, and respiratory protection. Work areas must be equipped with emergency eyewash stations and safety showers. Ensure the concentration of vapors remains below local occupational exposure limits.

What should I do if exposed to High purity Methacrylic Acid 99% min CAS 79-41-4?

In case of skin or eye contact, immediately flush with large amounts of water for at least 15 minutes and seek medical attention. If inhaled, move the person to fresh air. Always consult the SDS (Safety Data Sheet) provided by AECOCHEM for detailed emergency procedures.
