Handling hazardous dusts.
When working with power
tools, such as when grinding,
sanding, polishing, sawing or for other work
procedures where material is removed, dusts
develop that are both hazardous to one’s
health and can spontaneously combust or be
explosive.
Contact with or inhaling some dust types can
trigger allergic reactions to the operator or
bystanders and/or lead to respiratory infec-
tions, cancer, birth defects or other reproduc-
tive harm.
Examples of such materials which contain
chemicals that can produce hazardous dusts,
are:
–
Asbestos and materials containing asbes-
tos;
–
Lead-containing coatings, some wood
types such as beech and oak;
–
Minerals and metal;
–
Silicate particles from bricks, concrete and
other materials containing stone;
–
Solvent from solvent-containing paint/
varnish;
–
Arsenic, chromium and other wood pre-
servatives;
–
Materials for pesticide treatment on boat
and ship hulls;
–
Stainless steel dust, metal dust and non-
ferrous metal dust;
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 how
often these materials are worked. Materials
containing asbestos may only be worked on
by specialists.
Wood and light-metal dust can
cause spontaneous combus-
tion 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 rou-
tinely.
–
Observe the material manufacturer’s
working instructions.
–
Observe the relevant regulations for the
materials being worked.
