Industrial Laser Safety · EU Compliance

Safe machines start with informed decisions.

A website dedicated to educating users and the public about the dangers and requirements for safe laser machinery in Europe.

The core question

Laser safety — why bother?

We only have two eyes.

A split second of stray laser light is all that is required to irreversibly damage your vision.

With the explosion of desktop laser cutters aimed at schools, businesses and hobbyists, it is important to enable users to make informed decisions about the machines they are purchasing. Many are unaware of the potential life-altering risk. Bad manufacturers typically mislabel and do not conform with the essential health and safety directives.

Any machinery sold in the EU must comply with the applicable machinery law. Harmonised standards guide manufacturers on how to build a laser-safe machine.

European consumer-laser safety requirements also state that products must not cause eye damage or unintended skin damage from laser radiation under normal or reasonably foreseeable use, including momentary accidental exposure.

In short, consumer laser products must be designed so accessible radiation remains within safe classifications, particularly Class 1 or Class 2.

Laser processing
Material note

Laser safety windows and curtains must be rated for the specific wavelength and power of the embedded laser — a barrier that protects against one laser may fail against another.

Class 1

4 quick questions to check a Class 1 laser product

Ask these before you buy. A 'no' on any of them is a warning sign.

01

Declaration of Conformity?

Does the declaration match this machine and the applicable legislation? Under the Machinery Directive it is an EC declaration; the Machinery Regulation requires an EU declaration from 20 January 2027. Check the manufacturer, identification, legal references and signature.

02

Do you need to access the laser?

A true Class 1 product should not expose you to hazardous laser radiation during normal use and maintenance. Service may be treated separately.

03

Two-channel interlocks?

A single simple door sensor should not be the only safety function. The system needs suitable redundancy and fault detection so one failure cannot leave hazardous radiation accessible.

04

Are there warning stickers?

A cutting machine commonly contains an embedded Class 4 laser source. Service access, removable panels and embedded hazards should therefore carry the appropriate laser warnings.

*This is not an exhaustive list, but a good indicator the machine you are considering is indeed a Class 1 laser product.

EN 60825-1

Laser classification

How laser products are classified by hazard — and who they are suitable for.

Class 1

Laser product is safe during all foreseeable use. Suitable for everyone; home, schools, fablabs, etc.

Class 2

Laser product may cause harm but is very low risk due to the natural aversion or blink response. Do not deliberately stare into the beam.

Class 3R

Direct eye exposure can be hazardous. Appropriate controls and trained users are required.

Class 3B

High risk of permanent eye damage and possible skin injury. Professional controls and suitable protection are required.

Class 4

Highest hazard class, with severe eye and skin risk and often a fire hazard. Suitable only for controlled professional applications.

*Summarised from EN 60825-1:2014/A11:2021; some classifications have been omitted because they are less relevant to laser processing machines.

EU

Is a Laser Cutter a Machine?

Yes. If it is intended to burn, engrave and/or cut material through motorised CNC equipment, it is subject to European machinery law. The Federal Institute for Occupational Safety and Health (BAuA) has published a useful overview for laser products used as machinery.

Machinery law is changing in 2027

The existing guidance refers to Machinery Directive 2006/42/EC. Regulation (EU) 2023/1230 replaces that Directive and applies from 20 January 2027. Both are shown during the transition so older documentation remains understandable.

CE

Which documents should you check?

A CE mark alone is not enough — the paperwork must back it up.

CE marking

CE marking is the manufacturer’s declaration that the machine meets the applicable EU requirements. It is not, by itself, proof of independent testing or approval by an EU authority.

Look for a clear manufacturer name and address, machine identification and traceable supplier or importer details. The marking, manual and declaration should all refer to the machine you are buying. A logo or a general test certificate for one component is not a substitute for the conformity assessment of the complete machine.

EC or EU Declaration of Conformity?

The Declaration of Conformity (DoC) is the signed statement in which the manufacturer takes responsibility for the machine’s conformity. For machinery first placed on the EU market before 20 January 2027, the Machinery Directive 2006/42/EC requires an EC Declaration of Conformity. For machinery first placed on the market from 20 January 2027, the Machinery Regulation (EU) 2023/1230 requires an EU Declaration of Conformity. The date of first putting into service is relevant for machinery made for own use.

The change depends on the individual machine’s first placing on the market, not simply its manufacturing date or the date a buyer reads the document. Machines lawfully placed on the market before the change may continue to be made available under the transitional rules. An existing machine does not need a new declaration just because 20 January 2027 arrives.

Other legislation already uses the name EU Declaration of Conformity, including the EMC Directive and PPE Regulation. A combined EC/EU heading can therefore appear on current documents. Check the legal references and required contents, rather than judging conformity by the heading alone. For a machinery-only declaration, use the formal title for the applicable machinery legislation.

Match the manufacturer, model and serial or other traceable identification to the actual machine. Check the legislation, standards, issue date and authorised signature. A component certificate, test report or declaration of incorporation for partly completed machinery does not replace the declaration for a complete laser machine.

The official EU model PDF is provided by the European Commission. Use Annex V, Part A for complete machinery; its final signature fields continue on the second page. Part B is for partly completed machinery. This is the legal model structure, not a fillable form or a completed declaration.

Before 20 January 2027: EC Declaration — Directive 2006/42/EC, Annex II 1.A. From 20 January 2027: EU Declaration — Regulation (EU) 2023/1230, Annex V Part A.

EC format — required contents under Directive 2006/42/EC

Use the heading “EC Declaration of Conformity”. Annex II, part 1, section A requires the following information; conditional entries apply only where relevant.

  1. Manufacturer’s business name and full address; authorised representative’s details where applicable.
  2. Name and address of the person authorised to compile the technical file. This person must be established in the EU.
  3. Machine description and identification: generic name, function, model, type, serial number and commercial name.
  4. An express statement that the machine fulfils the relevant provisions of Directive 2006/42/EC and any other applicable legislation, with the official legal references.
  5. If applicable: name, address and identification number of the notified body that carried out EC type-examination, and the certificate number.
  6. If applicable: name, address and identification number of the notified body that approved the full quality assurance system.
  7. References to the harmonised standards used, where applicable.
  8. References to other technical standards and specifications used, where applicable.
  9. Place and date of the declaration.
  10. Identity and signature of the person authorised to sign for the manufacturer or its authorised representative.

The declaration must accompany the machine. Apply the Directive’s language and translation rules, and identify the original and any translation. The manufacturer or authorised representative keeps the original for at least 10 years from the last date of manufacture.

EU format — required contents from 20 January 2027

Use “EU Declaration of Conformity” and follow the model structure in Annex V, Part A. A declaration number is optional. Complete the fields for the actual machine and assessment route; this checklist is not a signed declaration.

  1. Product, type, model, batch or serial number; identify substantially modified machinery where applicable.
  2. Name and address of the manufacturer and, where applicable, its authorised representative.
  3. For the specified permanently installed lifting machinery assembled only at its place of use: the installation address. This is normally not applicable to a laser cutter.
  4. A statement that the declaration is issued under the manufacturer’s sole responsibility.
  5. Identification of the object of the declaration sufficient for traceability. A clear colour image may be included where needed.
  6. A statement of conformity with Regulation (EU) 2023/1230 and all other applicable EU harmonisation legislation, including publication references. Article 21 also requires stating that fulfilment of the applicable Annex III health and safety requirements has been demonstrated.
  7. References to the harmonised standards or common specifications actually applied, including the required date of publication of the harmonised-standard reference in the Official Journal or of the common specification. Give dated references for other technical specifications. Identify the parts used if a standard or common specification is applied only partly.
  8. Where applicable: notified-body name and number, the relevant assessment route and certificate reference — Module B followed by C, Module G, or Module H, as appropriate.
  9. Where applicable: state that the machinery is subject to internal production control (Module A). Do not assume Module A is permitted without checking the machine category and the Regulation’s assessment rules.
  10. Additional information, followed by: signed for and on behalf of; place and date of issue; signatory’s name, function and signature.

Use one EU declaration for all applicable EU acts requiring it, keep it updated and provide the language(s) required by the relevant Member State. Annex V no longer has a separate field for the person authorised to compile the technical file; the manufacturer’s documentation obligations remain.

Under Article 10(8), supply the declaration with the machine or provide its web address or machine-readable code in the instructions and Annex III information. The online declaration must remain accessible for the expected machine lifetime and for at least 10 years after placing on the market or putting into service. This future option is not a blanket permission to omit the current EC declaration.

Use only standards and editions actually applied and check their status under the relevant legislation. Do not copy the standards, dates or signature from the historical example below. Changing EC to EU on an old document does not establish compliance with the new Regulation.

Safety

Which safety features should you look for?

The enclosure, interlocks, safety control system, warning labels and how access is managed.

01

Machine enclosure

A Class 1 laser cutter keeps hazardous laser radiation inside a protective enclosure. An open cutting or engraving beam is not suitable for ordinary use at home or in a school; safety glasses alone do not turn an open machine into a Class 1 product.

The whole enclosure must protect you

The body, doors, viewing windows and openings must suit the laser’s wavelength and power. Protection must cover foreseeable faults as well as normal cutting. For example, a misaligned mirror may send the beam towards a door or frame instead of the workpiece.

Where a direct beam could strike, the design must prevent it burning through and exposing someone. The necessary resistance depends on the possible exposure and the protective measures, including how quickly the laser is safely stopped.

A tinted window is not proof of protection

A window that absorbs scattered CO₂ laser light may still burn through under a direct beam. Acrylic, polycarbonate, colour and thickness alone do not establish safety. The manufacturer must justify the window material and the beam path, including any measures that prevent a direct strike.

Ask your supplier

How have the enclosure and viewing window been assessed for this laser, including a foreseeable beam misalignment?

02

Interlocks

An interlock is a safety device that prevents hazardous laser emission when a protective door or panel is open. It must protect access during normal use and user maintenance wherever opening the enclosure could expose hazardous radiation.

Include cleaning and maintenance access

Check more than the main lid. Access for routine tasks, such as cleaning mirrors, also needs appropriate protection. Mirror alignment must follow the manufacturer’s procedure; work that exposes the beam needs specialist service controls. A panel used regularly for maintenance should not simply be treated as a service-only cover.

Look for fault detection and resistance to bypassing

The safety function must remain effective when faults occur and resist foreseeable bypassing, for example casual actuation with a loose magnet or piece of metal. EN ISO 14119 addresses interlock selection and measures against defeat.

An ordinary single switch is not equivalent to a complete safety system. Two safety channels and suitable monitoring can detect a failed sensor or wiring fault. One certified device may contain both channels, so counting physical switches is not enough. Non-contact safety devices also need the appropriate safety rating; IEC 60947-5-3 is relevant to suitable proximity devices.

Treat service-only panels differently

A fixed panel reserved for specialist service may use tool-operated fastenings or controlled key access instead of an operator interlock. It should not be opened during normal use. Follow the isolation and service instructions, and refit and secure all panels before returning the machine to use. Specialist live alignment requires separate protective measures; it is not normal Class 1 operation.

Ask your supplier

Which panels are interlocked, how are failures detected, and which cleaning or alignment tasks are intended for the user? Ask for the safe procedure; never defeat an interlock to check it.

03

Safety control system

The door sensor is only the start of the safety chain. Sensors, wiring, safety logic and the device that disables laser emission must work together. A signal saying “door open” is useful only if hazardous emission actually stops before it can reach you.

A fault must lead to a safe response

The system must monitor the protective devices and respond safely when a guard opens or a relevant fault is detected. Redundant channels help, but they also need suitable fault monitoring. Two switches connected to ordinary control software do not, by themselves, demonstrate a safe design.

Ask about the complete performance level

Performance level (PL) describes the reliability of a safety function. Ask which level is required and achieved, such as PL d, using EN ISO 13849-1 and the laser-machine requirements of EN ISO 11553-1. A component’s rating alone does not prove the whole function meets that level.

A suitable safety relay is one way to implement this. A manufacturer can also use an integrated safety system, provided the complete design is assessed and validated.

Ask your supplier

What stops laser emission if a door opens or a fault occurs, and what evidence supports the performance level of the complete safety function?

04

Warning labels

A Class 1 cutting machine can contain a powerful Class 4 laser. Class 1 describes the accessible radiation under the specified conditions; it does not mean that the source inside is harmless.

Warn before someone reaches the hazard

Service panels and areas where opening a cover could expose hazardous radiation need appropriate warnings. Removing covers or defeating protection can expose a hazard that is safely enclosed during normal use. A Class 1 product label is therefore not a reason to omit warnings about the embedded laser.

Look for the relevant laser class, wavelength and output information. Where the hazard is invisible, such as a CO₂ laser beam, the warning must make that clear. The exact wording and position depend on the product and the accessible radiation.

Include the risk of fire

Cutting uses concentrated energy that can ignite the material. Clear fire warnings and the operating instructions should explain supervision and what to do if a fire starts. Labels support safe use; they do not replace a protective enclosure or interlocks.

Ask your supplier

Are warnings visible before opening service areas, and do the manual and labels explain the laser and fire hazards?

05

Restricting access

Consider where the machine will be used: a locked workshop, a shared makerspace or a classroom with students. A Class 1 rating does not remove the need for instructions, appropriate supervision and control of fire and other process hazards.

Make authorised use straightforward

A key switch is not automatically required just because a machine is Class 1. It can, however, help prevent unauthorised use. Room access control, user authorisation and supervision may also be appropriate.

Decide who may use the machine, who holds the key or access permission, and who supervises learners. Operators should read the instructions and know the limits of permitted maintenance. Access control adds protection; it cannot compensate for an unsafe enclosure or interlock system.

Plan access and supervision

How will you ensure that only instructed users operate the machine and that students receive appropriate supervision?
