Specification:

1.Handling and Storage
Handling: Use spark-proof tools and explosion proof equipment. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. 
Storage: Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Store in a dry area. Refrigerator/flammables. Store under nitrogen. 
2.Fire Fighting Measures
General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. Will burn if involved in a fire. Containers may explode in the heat of a fire. Flammable liquid and vapor. 
Extinguishing Media: Use foam, dry chemical, or carbon dioxide. 
3.Reactivity Profile
 Methylacrylaldehyde (78-85-3) is an aldehyde. Aldehydes are frequently involved in self-condensation or polymerization reactions. These reactions are exothermic, they are often catalyzed by acid.
