The use of lasers and high-intensity light sources is now widespread in manufacturing across Ireland and the EU. Whether you are using lasers for cutting, welding, marking, cleaning, or research, one regulation applies across the board: the Artificial Optical Radiation Directive (Directive 2006/25/EC).

If your company uses lasers as part of their operations or services, understanding your responsibilities under this directive is essential. This helps ensure compliance and protect your staff from harm.

This blog outlines what the directive means in practical terms and what steps you must take to maintain high standards of laser safety, and compliance with this legislation.

The Artificial Optical Radiation Directive (AORD) sets the minimum health and safety requirements for protecting workers from exposure to artificial optical radiation, including laser and non-laser sources.

It applies to all employers in the EU and is implemented in Ireland under S.I. No. 176/2010. The directive covers risks to the skin and eyes from ultraviolet, visible, and infrared radiation.

Critically, the AORD applies to any workplace where artificial optical radiation is generated, including industrial lasers used in production, fabrication, or inspection processes. It also applies to newer applications such as laser cleaning.

Under the directive, employers must determine the level of exposure to artificial optical radiation from all laser and non-laser sources. Which includes the wavelength, intensity, and duration of exposure; the exposure limits set out in Annexes I and II of the AORD; and manufacturer data and technical specifications, where available.

The exposure assessment must be based on recognised standards such as IEC 60825 for laser products, and should reflect actual working conditions. This step forms the foundation for deciding whether further action is required to stay within safe limits.

Fortunately lasers are required to have a laser classification. Only Class 1 lasers fall under the safe limits. Lasers used in production, fabrication, and cleaning are class 4 lasers. Class 4 lasers emit laser radiation above the exposure limit values for the eyes and skin. So this step is already done for you, a risk assessment is required, as well actions, i.e. laser safety controls, to reduce the risk of exposure of laser light to an employee.

As exposure levels exceed the limits, a full laser risk assessment must be conducted. This includes identifying the potential hazards, including non-beam hazards associated with the laser, evaluating the effectiveness of current control measures, and outlining any additional steps needed to reduce risk.

Assessments must be performed by competent persons with appropriate laser safety knowledge and experience. You must document and regularly update your laser risk assessment, particularly when new equipment is introduced, existing processes are modified, or the scope of operations expands.

This is difficult if you lack time, resources, or staff with the expertise to assess and determine effective controls. This is where professional support can help. At Laser Protection Adviser Ltd, we help you meet your responsibilities under the directive by carrying out risk assessments, identifying practical control measures, and supporting you with the documentation needed to demonstrate compliance.

The Artificial Optical Radiation Directive sets strict exposure limit values (ELVs) to protect workers from harmful levels of ultraviolet, visible, and infrared radiation. These limits are based on established health risks to the eyes and skin.

However, in industrial settings, Class 4 lasers used for welding, marking, cutting, or surface cleaning routinely exceed these limits at the source. This is expected. The directive recognises that some equipment will exceed ELVs. So employer must ensure that exposures is controlled at the point of worker exposure.

This means your compliance obligation is not to eliminate high-power lasers, but to implement appropriate laser safety controls that reduce the risk of exposure.

The Artificial Optical Radiation Directive requires employers to ensure that all workers who may be exposed to artificial optical radiation receive appropriate information and training. This includes understanding the risks associated with laser exposure, the control measures in place, and how to work safely with or around laser systems.

Training should cover the specific hazards identified in your risk assessment, the correct use of personal protective equipment, and how to recognise and report signs of overexposure. It must also reflect the particular tasks, equipment, and environment in your workplace.

At Laser Protection Adviser Ltd, we design our training to meet the specific requirements set out in the Artificial Optical Radiation Directive. This includes training based on the outcomes of your risk assessment, the risks associated with your particular lasers, and the control measures that employees are required to follow. We offer on-site and online training to cover all required staff, including new hires.

Where there is a risk of adverse health effects or where exposures approach the limit values, appropriate health surveillance must be made available. This might include eye exams or medical checks, especially for staff in high-risk roles. The AORD Non-Binding Guide state that Following the invention of the laser, recommendations were published on routine eye examinations for laser workers. However, nearly 50 years of experience has shown that such examinations have no value as part of a health surveillance programme.

However, if there is a suspicion of a worker being exposed to laser light even if they do not show symptoms of overexposure they must be examined within 24 hours by an ophthalmology doctor. All medical incidents are reportable, including injuries causing or more than 3 consecutive days off work, and dangerous occurrences.

After any exposure or near miss the risk assessment must be reviewed and updated and investigate and adapt the protective measures. This will include taking into account the advice of the occupational health professional and the competent

Each Member State is required to enforce the AORD through penalties. In Ireland, the Health and Safety Authority (HSA) may take enforcement action under S.I. No. 176/2010. Failing to conduct a laser risk assessment, exposing staff to unsafe optical radiation levels, or not providing training can result in fines, prosecution, or shutdown of operations.

Demonstrating that your workplace meets the requirements of the directive is a legal obligation and is the foundation of safe and responsible operations.

Understanding and applying the Artificial Optical Radiation Directive can be complex, especially when dealing with high-powered or specialised laser systems. Laser Protection Adviser Ltd offers tailored laser safety services and laser safety training for industrial employers across Ireland and the EU.

From risk assessments to staff training and safety programme implementation, we help you meet your obligations under the directive and maintain a safe, compliant workplace.

Market surveillance is under-resourced. CE marks can be misleading. Your laser assessment is a vital step in keeping your patients, staff, and business safe.
