– Materials for pesticide treatment on boat
and ship hulls.
To minimize the unwanted intake of these
materials:
– Use dust extraction matched appropriately
for the developing dust.
– Use personal protective equipment, such as
a P2 filter-class dust protection mask.
– Provide for good ventilation of the work-
place.
The risk from inhaling dusts depends on the
frequency how often these materials are
worked. Materials containing asbestos may
only be worked by specialists.
Wood and light-metal dust can
cause spontaneous combustion
or explosions.
Hot mixtures of sanding dust and paint/var-
nish residuals or other chemical materials in
the filter bag or the vac filter can self-ignite
under unfavourable conditions, such as spark-
ing from sanding metal, continuous sunlight
or high ambient temperatures. To prevent
this:
– Avoid overheating the material being
sanded and the power tool.
– Empty the dust collector/container in time.
– Observe the material manufacturer’s work-
ing instructions.
Observe the relevant regulations for the
materials being worked.
