MMA is a flammable liquid which fulfils the classification criteria for
H225 (Highly flammable liquid and vapour). Based on the chemical
structure, MMA does not have explosive or oxidising properties, because
the structural elements associated with those properties are absent.
When the normal safe handling practice for highly flammable substances
is obeyed, the risk for workers or consumers arising from this property
can be adequately controlled, e.g. where appropriate by the following
Source of Ignition
•Electrostatic discharge may cause fire
•Ensure electrical continuity by bonding and grounding (earthing) all
•Do NOT use compressed air for filling, discharging or handling
•Electrostatic charges may be generated during pumping.
•Restrict line velocity during pumping in order to avoid generation of
•If positive displacement pumps are used, these must be fitted with a
non-integral pressure relief valve.
•Extinguish any naked flames. Do not smoke. Remove ignition sources.
•The vapour is heavier than air, spreads along the ground and distant
ignition is possible.
•Use appropriate equipment for filling IBCs and other containers. IBCs
and other containers must be constructed of appropriate material.
•Handle and open container with care in a well-ventilated area.
•Use only with adequate ventilation.
•Do NOT empty into drains.
