3. Potential hazards related to materials worked with
Fumes and toxic particles
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
For a more detailed list of the risks related to the material worked with, consult Annex A of the ISO 11553-1:2005
norm.
In this case, adapt an extraction system (with filtration if necessary) to the marking station. This system vacuums
eventual emissions from the marking area.
It must be linked to:
• either a centralised vacuum system with an external evacuation.
• either an independent system dedicated to the marking station, which removes fumes and particles using
activated carbon filters.
The user must observe national legislation in force concerning chemical agent exposure limits.

Examples of secondary radiation risks
The use of a class 4 laser device can generate:
• a risk of fire or explosion due to materials or inflammable substances
• UV radiation
•X rays
• high intensity visible light when marking on certain materials
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.
