ETHYL ACRYLATE 140-88-5	The vapour is heavier than air and may travel along the ground; distant ignition possible • Vapours are uninhibited and may form polymers in vents or flame arrestors, resulting in stoppage of vents	The substance may polymerize spontaneously due to warming and under the influence of light	3
ETHYL METHACRYLATE 97-63-2	The vapour mixes well with air, explosive mixtures are easily formed	The substance may polymerize violently due to warming and under the influence of light or when in contact with strong oxidants	3
2-ETHYLHEXYL ACRYLATE 103-11-7		The substance may polymerize due to heating under the influence of acid, alkalies, amines, peroxides, oxidizing agents
2-HYDROXYPROPYL ACRYLATE 999-61-1		The substance can polymerize due to heating, initiators, UV light • The substance decomposes on heating producing acrid fumes (acrylic acid, acroleine)	8
