Laser marking, engraving, welding and cutting systems, are now
used throughout industry, education establishments and in
research facilities to process a wide and varied range of
Most of these lasers burn away layers of the material
to make a cut or mark, this causes the emission of hazardous
toxicological particles and gas.
Examples are benzene and toluene
from certain plastics and chromium and nickel from metals.
Virtually all materials when processed will emit some fumes that
are hazardous to the health of the operator; even seemingly
harmless materials such as cardboard and paper labels can produce
respirable dust and formaldehyde.
environmental legislation deems that exhausting hazardous fumes
outside into the atmosphere is becoming a restricted option, so
the alternative is a filtration system.
It is imperative to
ensure the laser operator is not exposed to hazardous fumes from
the process and so only the correct type of fume extraction
system should be installed.
Any system should take into account
factors such as the laser make and model, the airflow required,
the volume of hazardous material produced, the fume composition
and many other factors.
To help the laser operator and their
employers, Purex International has developed a new website
containing process survey forms that the laser operator can use
to fill in their process detail and find out which extraction
system is required.
There are separate forms for laser marking,
engraving, welding and cutting applications as well as resources
such as links to health and safety information and other laser
