2.12 Decomposition Products
WARNING
When treating materials with laser radiation decomposition products are produced
which are dangerous to health!
Through vaporization of materials fine dust and vapors are produced which might
include hazardous decomposition products depending on type and composition of
the respective materials.
A fume extractor according to the respective requirements which is equipped with
special dust and activated charcoal filters must be installed to ensure that the de-
composition products are removed from where they are produced.
When treating materials with laser radiation the national and relevant regulations
for air purification at work must be observed. Those regulations can result in fur-
ther, detailed requirements regarding the performance of the fume extractor or
the air recirculation to the workplace.
This can be the case marking different plastics, e.g. POM (polyoxymethylene),
ABS (acrylonitrile butadiene styrene), SAN (styrene acrylonitril copolymer), HDPE
and LDPE (polyethylene), PAN (polyacrylonitrile), PBT (polybutylene terephtha-
late) or different tool steels, e.g. with chromium additions.
Marking those materials the formation of carcinogenic substances cannot be
ruled out. This can result in the prohibition of the air recirculation to the work-
place, i.e. the fume extraction system must lead the exhaust air outside into the
atmosphere.
The company operating the system for treatment of material surfaces using laser
radiation is responsible for meeting the local codes and regulations. Additionally,
the safety instructions of the operating instructions must be observed.
Protect yourself and your colleagues against hazardous decomposition products!
A fume extractor also prevents contamination and gradual destruction of optical
elements of the beam delivery system by dust particles. We offer different fume
extractors as accessories.
