Safe Handling and Regulatory Status
Methyl Acetate (cas 79 20 9) is highly flammable, posing fire hazards due to its low flash point of approximately -10 °C (14 °F). Since its vapors are heavier than air, they can travel considerable distances to an ignition source and cause a flashback. Handling requires the use of explosion-proof equipment and ensuring all containers are grounded to prevent static discharge.
Regarding health hazards, methyl acetate is an irritant, primarily affecting the eyes and causing serious irritation. Exposure to high concentrations of vapors can also irritate the respiratory tract, potentially causing drowsiness or dizziness. Proper personal protective equipment, such as protective goggles and butyl rubber gloves, is recommended to prevent eye and skin contact.
Storage must be in cool, dry, and well-ventilated areas, kept away from heat sources, open flames, and incompatible materials like strong acids, bases, and oxidizing agents.
