Laser safety & CE certification

Laser safety

MetaQuip laser machines use high laser powers for cutting or engraving. In a number of machines visible laser light is used, in a number of cases invisible laser light. In any case, it is always very careful, because this kind of laser light on skin or in the eyes can be very harmful.

Laser safety means a good and safe design of the laser machine that ensures the safety of all trained and untrained operators.

What are the different laser classes?

1st ClassMachine is in normal use in all situations safe.
Class 2MVisible lasers. Safe for incidental exposure (<0.25 s).
Class 3RNot safe. Low risk.
Class 3BDangerous. Watching scattered reflections is safe.
Class 4Dangerous. Looking at scattered reflections is also dangerous. Fire risk.


A class 1 laser is always safe without further safety measures such as laser glasses. Especially in CO2 laser machines that are often used in schools, it is essential that a laser machine is a tested laser class 1 device to prevent unsafe situations at all times.
Note: Lasers contain high power invisible light sources that can easily damage eyes and cause burns! Do not take any risks with this.

CO2 laser machines

MetaQuip closed CO2 lasers to be laser class 1 machines. MetaQuip CO2 laser machines are equipped with fail safe switches that can not be bridged with a finger or magnet and ensure that the laser is not only deactivated with software but also hardware. Users are thus protected against unintentional "abuse" in order not to be exposed to laser energy above the legal European standards. MetaQuip closed CO2 laser machines are therefore always safe. This has been concluded by independent experts and described in measurement reports.

If you have a open CO2 machine wish this will class 4 to be. In that case, serve all persons to provide sufficient protection in the room to prevent possible damage from exposure, such as laser glasses. This kind of machines are less suitable for applications where a laser is placed in a freely accessible space (as is usually the case with schools). Always contact MetaQuip for advice. If necessary, MetaQuip can refer you to specialists who can advise you on your situation.

Fiber lasers

The closed fiber lasers his laser class 3R, a conscious choice to give the customer access to the laser space when the circumference of the laser object is shown with a red contour laser.

Open fiber lasers are examples of this class 4 laser machines. So they serve in one closed room to be placed and people in the room should wear safety goggles. Access to the room must be accompanied by a warning that a class 4 laser is present in this room and an indication (lamp or sign) when this laser is active.

Machine construction

MetaQuip machines are built so that laser light can never leak out of the machine, allowing the user or bystander to be exposed to the laser light. This has been checked on the basis of light measurements by an independent inspection body. Well safe!

Interlock safety switches

The moment the user opens the laser door or one of the panels to clean, for example, all lasers in the machine switch off immediately. Both the high power laser and the small red dot laser. This makes MetaQuip CO2 laser class 1 devices, where no further measures have to be taken by the user regarding laser safety. Having approved interlock safety switches is OBLIGATED if a supplier wishes to comply with the CE machine guidelines and applicable laser safety regulations. A simple switch is not safe and can easily be bridged!

CE certification & machine guidelines

MetaQuip products are CE certified. This means that MetaQuip machines comply with all requirements and standards applicable in Europe (including machine guidelines and laser safety requirements). As a result, our machines are maximally safe for the user even when unforeseen situations occur. We think this is important because the laser power used can have very harmful consequences for users and bystanders. Work is often done with invisible light, but if eye damage occurs, this is often permanent! Always let others know well which guidelines have been followed and which tests have been carried out. Reliable parties in the market have their affairs in order will show you with pleasure.

CE certified CO2 laser machine


These machines follow:

  • Machine directive 2006/42 / EC,
  • Low voltage directive 2006/95 / EC, EMC directive 2004/108 / EC

In line with European standards and directive documents:

  • NEN-EN-IEC 60204-1: 2006 (electrical equipment or machines)
  • NEN-EN-ISO 122100-1: 2010 (Safety of machinery - basic concepts for design, risk assessment and risk reduction)
  • NEN-EN-IEC 60825-1: 2014 (Safety of laser products - Part 1: Equipment classification and requirements)
  • NEN-EN-IEC 60825-4: 2006 (Safety of laser products - Part 4: Laser shielding)
  • NEN-EN-IEC 11553-1: 2009 (Safety of machinery - machines that use lasers - safety regulations).
Air extraction for CO2 lasers

Laser open? Immediately all lasers out

The interlock safety system makes it virtually impossible for a user to come into contact with any kind of laser light. At MetaQuip we find this as safe as we also deliver a lot to schools and fablabs.

Air extraction

When cutting or engraving various materials, harmful fumes and gases can be released. It is therefore of great importance that the exhaust system is carefully considered and not cut back on it. MetaQuip can advise you on the best solution for your situation.
