Other hazards which do not result in classification
Vapours are heavier than air. Vapours may travel across the ground and reach remote ignition sources causing a flashback fire danger. Highly reactive. Maintain dissolved oxygen and inhibitor at proper levels to prevent runaway polymerisation. May form flammable/explosive vapour-air mixture. This material is a static accumulator. Even with proper grounding and bonding, this material can still accumulate an electrostatic charge. If sufficient charge is allowed to accumulate, electrostatic discharge and ignition of flammable air- vapour mixtures can occur.
