Security & Safety Guidelines
Basic Information
The Ortur Laser Master 2 Pro engraves and cuts materials by the means of a
high-energy diode laser beam.
The hazards associated with a high-energy diode laser beam include the
possibility of res, generation of hazardous and/or irritating toxic fumes, but more
importantly damage to eyes and skin.
International Classications
Laser engravers are divided into several internationally valid classes based
on their performance and the risk of injury. For the scope of this guide we will
focus on the American FDA classication, even though there are similar other
classication tables.
The Ortur Laser Master 2 Pro falls into the Class IV (Class 4 IEC standard)
as it’s an open, non-enclosed laser engraver, therefore Personal Protective
Equipment (PPE) should be worn at all times – by everyone in the proximity of
the machine, when operating the Ortur Laser Mater 2 Pro.
If you enclose your Ortur Laser Master 2 Pro, make sure the enclosure follows
the above classication guidelines and complies with the international standards.
Laser class Class Denition
Class I Class I laser radiation is not considered hazardous.
Class IIa Class IIa laser radiation is not considered hazardous if viewed for any period of
time less than or equal to 1x103 seconds, but is considered a chronic viewing
hazard for any period of time greater than 1x103 seconds.
Class IIa Class II laser radiation is considered a chronic viewing hazard.
Class II Class IIIa laser radiation is, depending upon the irradiance, either an acute in-
trabeam viewing hazard or chronic viewing hazard. If viewed directly with optical
instruments, Class IIIa laser radiation is classied as an acute viewing hazard.
Class IIIb Direct Class IIIb laser radiation is considered an acute hazard to the skin and
eyes.
Class IV Class IV laser radiation is considered an acute hazard to the skin and eyes from
both direct and scattered radiation.

Hazards and Precautions
Laser Light
The high energy laser beam can cause severe eye damage,
including blindness and serious skin burns.
Improper use of the controls and modication of the safety features
may cause serious eye injury and burns.
It is recommended to select a room to operate the Ortur Laser Master 2 Pro
where access can be controlled by means of a solid door. No direct view to the
laser beam should be possible from the outside. When possible, a signs should be
used to indicate the Ortur Laser Master 2 Pro is in Operation.
• DO NOT look directly into the laser beam;
• DO NOT aim the laser beam at reective surfaces;
• DO NOT operate the laser without PPE protection for all persons nearby in the
proximity of the Ortur Laser Master 2 Pro
• DO NOT allow unsupervised access to the Ortur Laser Master 2 Pro to
children;
• DO NOT allow access near the Ortur Laser Master 2 Pro to pets;
• DO NOT modify or disable any safety features of the laser system;
• DO NOT touch the high energy laser beam;
Personal Protection Equipment (PPE)
Laser Safety glasses are mandatory at all times when adjusting and
operating the Ortur Laser Master 2 Pro. These should be worn by
the user and any person in the proximity of the Ortur Laser Master
2 Pro.
• Safety Glasses are designed to lter specic ranges of laser wavelength. The
Ortur Laser Master 2 Pro Safety Glasses provided are specic for Ortur Laser
Module;
• If you wish to purchase additional Safety Glasses, these must be applicable to
the Ortur Laser Master 2 Pro Laser Module (wavelength and optical density);
Ortur Laser Master 2 Pro Laser Module has a wavelength of 445nm –
the Rating of the Safety Glasses should be no less than O.D. 4;
Note: the tint/colour of the Safety glasses is not an indication of their specication

Fire Hazard
The high-energy diode laser beam can produce extremely high
temperatures and signicant amounts of heat as the substrate
material is burned away while engraving and cutting. Some
materials are prone to catch re during cutting operations creating
ame, fumes and smoke.
Although the Ortur Laser Master 2 Pro has a built in ame sensor, this
technology should NOT be considered 100% accurate and should be seen
only as a warning system.
The ame sensor does not have the ability to extinguish ames.
The sensor can only alert the user for the possibility of a ame on
the machine. Do not ignore the Flame sensor Alarm!
It is recommended to select a room to operate the Ortur Laser Master 2 Pro
where access to good ventilation is available as well as make the working
area as re proof as possible. It is important that user remain with the laser
during operation to ensure that any are ups/ ame are properly contained and
extinguished.
It is strongly recommended that a Fire Extinguisher should be located within
close proximity to the Ortur Laser Master 2 Pro. Extinguishers should be
halogen or multi-purpose dry chemical. Alternatively or in conjunction with the Fire
Extinguisher it is recommended a “Fire Extinguisher Ball” is positioned beside the
Ortur Laser Master 2 Pro.
• DO NOT use materials that are highly ammable, explosive or produce toxic
by-products;
• DO NOT remove material from the cutting bed before it has cooled;
• DO NOT leave the Ortur Laser Master 2 Pro operating unattended;
• ALWAYS clean up clutter, debris and ammable materials in the laser Ortur
Laser Master 2 Pro bed after use;
• ALWAYS keep a properly maintained re extinguisher nearby;
• DO NOT allow the USB cable to come in contact with the laser Beam;
• DO NOT allow the 24v power cable to come in contact with the laser Beam;

Laser Generated Air Contaminants
Laser engraving or cutting will generate fumes, vapours and
particulates from the substrate material that can be highly toxic.
Is recommended to select a room to operate the Ortur Laser
Master 2 Pro where access to good ventilation is available and
proper ventilation is maintained at all times when the Ortur Laser Master 2 Pro is
in operation.
Although most of the recommended materials for engraving on the Ortur Laser
Master 2 Pro are safe, the user should seek information each time a new material
is used.
Some materials, specially plastic based, will generate highly toxic
fumes that are - not only - very health hazardous but can also
damage and corrode your Ortur Laser Master 2 Pro metal frame.
Below a list of some of the most known hazardous materials that the user
SHOULD NOT attempt to engrave or cut on. If a material is not in this list, do
not consider it to be safe to use. Obtain the Safety Data Sheet (SDS) from the
material’s manufacturer when handling unknown materials.
Material Reason to avoid engraving / cutting it
PVC (Poly Vinyl
Chloride)
PVC will emit Chlorine gas when laser cut or laser engraved. This toxic gas can
ruin the optics and motion control system of the laser engraver, In fact, engraving
or cutting PVC is a sure way of voiding the warranty of your laser engraver
Lexan / Thick Poly-
carbonate
Lexan not only cuts poorly but it also catches on re very easily. The window of
the laser engraving machine is usually made from polycarbonate because it does
a very good job of attracting infrared radiation., which is the frequency of light the
engraver uses when cutting and engraving materials. This makes the laser cutter
quite ine󰀨ective in cutting polycarbonate materials
ABS ABS melts upon exposure to a laser beam as opposed to vaporizing which would
be the ideal reaction needed for laser engraving. Instead of leaving a crisp image,
ABS will melt and leave a gooey deposit on the surface.
HDPE HDPE melts and catches on re pretty easily upon exposure to a laser beam.
Polystyrene Foam Only very thin pieces can be laser cut but for the most part, polystyrene catches
on re and melts when exposed to a laser beam
Fiberglass Fiberglass is made from two materials; glass and epoxy resin. The best method
of marking glass is etching while epoxy resin can emit toxic fumes upon laser
engraving. These two reasons make berglass a bad choice for a laser engraving
material
Polypropylene polypropylene melts and catches on re easily and then the melted material con-
tinues to burn thereby forming pebble-like drips that harden on the surface
Coated Carbon
Fiber
Coated carbon ber emits noxious fumes. Additionally, carbon ber can be cut
albeit with some fraying but this is not the case when it is coated.
