In the Netherlands, industrial lighting is subject to both national and European safety requirements, laid down in NEN-EN standards, ATEX directives, and Dutch occupational health and safety legislation (Arbowetgeving). These requirements specify minimum illumination levels, emergency lighting requirements, protection classes, and explosion safety. They apply to any employer who has employees working in industrial environments. In this article, we will answer the most frequently asked questions about lighting standards in the industry.

What Dutch and European standards apply to industrial lighting?

The foundation lies in NEN-EN 12464-1, the European standard for indoor workplace lighting. This standard specifies minimum illuminance levels, uniformity, and glare limitation for various work areas. In the Netherlands, compliance is mandatory through the Working Conditions Act (Arbowet), which requires employers to provide a safe and healthy work environment, including adequate lighting.

For outdoor workplaces, EN 12464-2, relevant for grounds, harbors, construction sites, and other outdoor environments. In addition to these standards, the following regulations also play a role:

• Arbobesluit, Article 6.2: Require employers to provide adequate daylight and artificial lighting in the workplace
• ATEX Directive 2014/34/EU: for lighting in explosion-hazardous areas
• EN 1838: the standard for emergency lighting and escape route lighting
• CE Marking All luminaires placed on the EU market must comply with the relevant product directives.

It is important to understand that these standards together form a framework. The Working Conditions Act (Arbowet) establishes the legal obligation, while the NEN-EN standards provide the technical implementation of what “adequate lighting” means in practice.

Illuminance levels per type of industrial workplace

The more precise or risky the work, the higher the minimum illuminance. The required illuminance, expressed in lux (lx), therefore differs depending on the type of workplace and task. NEN-EN 12464-1 uses specific values per task description for this.

Here are some guidelines from the standard for industrial environments:

• Aisles and storage areas: at least 100 lux
• General production areas: minimum 200 lux
• Machine operation and assembly: 300 to 500 lux
• Precision work and quality control: 750 lux or more
• Outdoor areas and parking lots: 10 to 50 lux, depending on use

In addition to illuminance, the standard also prescribes uniformity requirements. The light must be evenly distributed, without large dark spots or harsh contrasts. A high uniformity value (Uo) increases visual safety and reduces fatigue for employees. For the correct application, it is advisable to have a professional lighting calculation performed before selecting luminaires - more on this on the page lighting expertise.

What are the requirements for emergency lighting in industrial environments?

Emergency lighting in industrial environments must comply with EN 1838 and the supplementary requirements from the Building Decree. The standard distinguishes between two types: escape route lighting (for safe evacuation) and emergency escape lighting (for orientation in larger spaces). Both must activate automatically when the normal lighting fails.

The minimum requirements for emergency lighting are:

1. Minimum illuminance of 1 lux on the floor of escape routes
2. Minimum illuminance of 0.5 lux for anti-panic lighting in open spaces
3. Minimum burning time of 1 hour (in many industrial applications, 3 hours is required)
4. Activation within 5 seconds after power failure
5. Regular inspection and documentation of operations

In the industry, additional requirements often apply, depending on the risk profile of the environment. Examples include longer fire resistance ratings, increased lighting levels around hazardous machinery, or mandatory emergency lighting above emergency stop buttons. The company's Risk Assessment and Evaluation (RI&E) also helps determine which additional requirements apply.

What additional requirements apply to lighting in ATEX zones?

Where there is a risk of explosion from flammable gases, vapors, or dust, strict additional requirements apply to all electrical equipment — including lighting. Luminaires must be certified according to the ATEX Directive 2014/34/EU and be provided with the correct Ex marking indicating which zone and type of explosion hazard they are suitable for.

The ATEX zoning determines which equipment is permitted:

• Zone 0 / Zone 20: continuous presence of explosive atmosphere (gas or dust) — requires category 1 equipment
• Zone 1 / Zone 21: regular presence of explosive atmosphere — requires category 1 or 2
• Zone 2 / Zone 22: Incidental presence — Category 1, 2, or 3 Required

In addition to ATEX certification, luminaires in these zones must also comply with regular lighting standards. The combination of explosion protection, sufficient light output, and mechanical robustness makes ATEX lighting a specialized application. For environments with extreme corrosion in combination with ATEX requirements—such as chemical plants or offshore installations—the page on lighting for extreme corrosion useful background information.

IP class and IK rating: what does that mean for safety compliance?

Two classes you regularly encounter in practice: the IP class (Ingress Protection) and the IK class. The first indicates the degree to which a fixture is protected against the ingress of dust and water; the second describes the resistance to mechanical impacts. Both are directly relevant to safety compliance, as fixtures in industrial environments must withstand the specific conditions of the location.

For most industrial applications, the following guidelines apply:

• IP54: minimal for dusty production environments without direct water exposure
• IP65 or higher required for water jet cleaning processes or outdoor applications
• IP67 or IP68: for immersion or use in wet process environments
• IK08 or higher: Recommended in environments with vibrations, vehicle traffic, or risk of collisions

A fixture with an insufficient IP or IK rating can fail prematurely, leading not only to downtime but also to safety risks due to damaged electrical components. Correctly selecting the protection class is therefore part of the employer's statutory duty of care. You can find more about the meaning of these classes on the page about IP and IK rating.

Who is responsible for compliance with lighting standards in a company?

The ultimate responsibility always lies with the employer—this is stipulated in the Dutch Working Conditions Act (Arbowet). In practice, this responsibility is delegated internally to specific roles, depending on the organizational structure.

Typically, the following roles are involved in lighting compliance:

• HSE Manager or Safety Officer monitors compliance with occupational health and safety legislation, including lighting requirements
• Facility manager or technical manager responsible for maintenance and replacement of lighting installations
• Plant Operations Manager Ultimately responsible for the work environment and the risk assessment
• Project manager or engineer: responsible for correct specification in new construction or renovation

The Risk Assessment and Evaluation (RI&E) is the central instrument. It identifies lighting risks and records measures. Periodic measurement of illuminance and documentation of maintenance are mandatory components of a demonstrable safety policy. If there is doubt about the current situation, a professional lighting scan can offer a solution.

Examples from practice: DFDS Terminal Lighting

A concrete example of how lighting standards work in practice is the project for DFDS, a large European ferry and freight operator with a busy terminal. The operational challenge was multifaceted: the terminal operates 24 hours a day, seven days a week, meaning lighting cannot simply be taken out of service for maintenance. At the same time, the new installation had to meet the illuminance levels from EN 12464-2 for outdoor workplaces, including requirements regarding uniformity and glare limitation.

The technical challenge lay in combining high light output with a long lifespan and low maintenance requirements – essential in a location where downtime has direct operational and financial consequences. Robust LED fixtures with a high IP rating, suitable for the salty and humid port environment, were chosen. The mast installation was designed to ensure future maintenance can be performed safely and efficiently, without disrupting terminal operations.

Those who underscore this project: compliance doesn't start with fixture selection, but with a sound lighting design that takes into account operational constraints, maintenance cycles, and the specific standards for the location. More examples of similar projects can be found at projects page.
