Material Safety Instructions - Omtech MOPA LYF-20MP User Manual

2.5 Material Safety Instructions

• Users of this fiber marking machine are responsible for confirming that materials to be processed can withstand
the heat of the laser and will not produce any emissions or byproducts either harmful to people nearby or in
violation of any local or national laws or regulations. In particular, DO NOT use this machine to process polyvinyl
chloride (PVC), Teflon, or other halogen containing materials under any circumstances.
• Users of this fiber laser are responsible for ensuring that every person present during operation has sufficient PPE
to avoid any injury from emissions or byproducts of the materials being processed. In addition to the protective
laser eyewear discussed above, this may require goggles, masks or respirators, gloves, and other protective outer
clothing.
• Users MUST exercise special caution when working with conductive materials as buildup of their dust and
ambient particles may damage electrical components, cause short circuits, or produce other effects including
reflected laser radiation.
This machine can be safely used with the following materials:
• Aluminum
• Brass
• Carbide
• Gold
• Silver
• Steel
• Stone, including Granite, Marble, etc.
• Titanium
• Tungsten
This machine can be used with some other metals, hard plastics, and other materials with some care. For other
materials, if you are unsure about its safety or laserability with this machine, seek out its material safety data sheet
(MDS).
Pay especial attention to information about safety, toxicity, corrosiveness, reflectivity, and reaction(s) to high heat.
Alternatively, contact our support department for further guidance.
See Instructions for Specific Materials (Page 17) for the recommended parameter values for the most commonly
engraved materials.
This machine CANNOT be used with the following materials or with any materials which include them:
Materials
Artificial Leather containing Hexavalent Chromium (Cr[VI])
Astatine
Beryllium Oxide
Bromine
Chlorine, including Polyvinyl Butyral (PVB) and Polyvinyl
Chloride (PVC, Vinyl, Cintra, etc.)
Fluorine, including Polytetrafluoroethylenes (Teflon, PTFE, etc.)
Iodine
Phenolic Resins, including various forms of Epoxy
Paper and Paperboard
Reasons
Due to their toxic fumes.
Due to their high flammability when
exposed to the concentrated laser.
