Laser safety

Potential hazards related to materials worked with
Fumes and toxic particles
Laser marking certain materials emits dangerous fumes and particles
that may be toxic and/or damage the equipment. In this case, adapt an
extraction system (with filtration if necessary) to the marking station.
The user must check the compatibility of marked or engraved materials with the laser
type.
The processing of parts using this type of Laser causes thermal and photo-electric (molecular) deterioration
of the material. Even micro-quantities of the by-product (soot or fumes), created during Laser marking, may
accumulate over a long period. Some of these by-products may prove to be hazardous to humans.
Health side-effects to the operators may include poisoning, allergies or cancer.
Here are some examples of the most sensitive materials:
• plastics and rubber
• painted materials
•
anodized and galvanized metals
• ceramics
•
materials containing lead or mercury
Do not cut, engrave or mark PVC-based (polyvinyl chloride) materials. The fumes are
extremely toxic and can chemically destroy the metal parts of the machine.
For a more detailed list of the risks related to the material worked with, consult Annex A of the ISO 11553-
1:2005 standard.
Laser marking certain materials emits dangerous fumes and fine particles that may damage health. The fumes
and fine particles may damage the equipment.
Recommendations: Use an adapted extraction system with 3 levels of filtration: a pre-filter for large particles,
a HEPA filter (retaining 99.97% of 0.3 µ particles) for fine particles and an activated carbon filter for dangerous
fumes. The fume capture inlet should be as close as possible to the marking area.
The user must observe national legislation in force concerning chemical agent exposure limits.
