Risks in connection with polymer materials
Working on painted surfaces
WARNING'
All paint decomposes when heated and forms a great
number of compounds. These substances may be irritating
and after long or frequent exposure may constitute a
serious health hazard.
NOTE:
Always use a respirator during all removal of paint.
— When welding and cutting, the paint finish must first be re-
moved from an area with a radius of at least 10 cm (4 in) from
the point of welding or cutting. Paint which is heated gives off
poisonous gases.
— Never weld directly on a painted surface. In addition to the
health hazard, the weld will be of inferior quality and strength,
which, in the future, may cause the weld to break.
— Remove the paint from the area where work it so be carried out
by sand blasting.
If the paint cannot be removed by sand blasting, it must be re-
moved in some other way, e.g. with a paint stripper.
NOTE:
When using paint stripper, use a portable air extractor, an ap-
proved respirator and protective gloves.
—
A high-speed grinding machine also heats the paint and must
only be used in conjunction with a portable air extractor.
Rubber and plastics
NOTE:
Polymer materials can, when heated, form compounds which
are dangerous to health and environment.
Do not weld or cut near polymer materials (plastics and rubber
components) without first having protected them from the heat.
Never burn polymer materials when scrapping them.
Take care when handling machines which have burnt or been
exposed to intense heat.
Always use gloves, protective goggles and an approved respi-
rator.
