Flammable liquids
Highly flammable liquids present a particularly
high fire risk. For example, a leak from a
container of flammable solvents, such as acetone,
may produce large quantities of heavier-thanair flammable vapours. These can travel large
distances, increasing the likelihood of their
reaching a source of ignition well away from
the original leak, such as a basement containing
heating plant and/or electrical equipment on
automatic timers.
