How Arbejdstilsynet Inspects Construction Sites: 2026 Guide

For any Polish foreman working on a Danish construction site, understanding how Arbejdstilsynet, Denmark's national Working Environment Authority, evaluates workplace safety is not optional. It is the difference between a smooth inspection and a work stoppage order that can halt an entire project. Arbejdstilsynet has broad powers to enter any construction site unannounced, issue improvement notices, and in serious cases suspend work immediately. Knowing what inspectors look for, and preparing your crew accordingly, is one of the most valuable things a brigade leader can do in 2026.

What Is Arbejdstilsynet and Why Does It Matter to Polish Workers?

Arbejdstilsynet operates under the Danish Ministry of Employment and enforces the Danish Working Environment Act (Arbejdsmiljøloven). Its inspectors visit workplaces across all sectors, but construction has historically been one of the most scrutinised industries because of the physical risks involved, working at height, heavy machinery, excavation, and exposure to hazardous substances all feature prominently on Danish sites.

Polish workers make up a significant share of the construction workforce in Denmark, and Polish-speaking brigade leaders often serve as the primary point of contact between a Danish main contractor and a subcontracted Polish crew. That means the foreman carries real responsibility. If Arbejdstilsynet finds violations, the legal consequences can fall on the employer of record, but the practical fallout, production delays, strained client relationships, potential repatriation of workers, lands squarely on the brigade.

Step 1: Understand the Legal Framework Before the Inspector Arrives

The starting point is the Arbejdsmiljøloven itself, which sets out the general duty of care for all employers operating in Denmark, regardless of whether the company is Danish or foreign. Supplementary executive orders (bekendtgørelser) cover specific risks: working at height, scaffolding, personal protective equipment, noise, and chemical agents. Arbejdstilsynet publishes its inspection criteria and sector-specific guidance on its official website at at.dk, and foremen should treat that portal as a primary reference.

Foreign employers, including Polish staffing agencies and subcontractors, are subject to exactly the same rules as Danish companies once their workers set foot on Danish soil. There is no exemption for posted workers. If your crew is posted under EU posting rules, compliance with Danish working environment law is mandatory from day one. Tracking working hours accurately is also part of this picture; you can read more about the digital obligations in our guide on Digital Time Tracking Under LOV 89: A 2026 How-To Guide.

Step 2: Assemble the Documents an Inspector Will Ask For

When an Arbejdstilsynet inspector walks onto your site, the first thing they typically request is documentation. A foreman who cannot produce the right paperwork immediately signals disorganisation, and inspectors notice. The core documents you should have ready at all times include:

• The site's APV (arbejdspladsvurdering), a written workplace risk assessment. Every employer is legally required to have one.
• Records of safety instruction and induction for each worker, including those who joined the crew recently.
• Certificates for equipment operators where certification is required (crane operators, forklift drivers, scaffolding erectors).
• Chemical safety data sheets (sikkerhedsdatablade) for any hazardous substances on site.
• Emergency and first-aid procedures, posted visibly and understood by the crew.
• Working time records, which must be kept accurately under Danish law.

Missing or incomplete documentation is one of the most common triggers for an improvement notice. Prepare a physical folder and a digital backup. If your company uses a digital HR or site management platform, make sure records can be exported quickly on a mobile device.

Step 3: Walk the Site Through the Inspector's Eyes

Beyond paperwork, Arbejdstilsynet inspectors conduct a physical walkthrough. They are trained to spot hazards that workers may have normalised over time. As a foreman, you should conduct your own pre-inspection walkthrough at least once a week, asking yourself the same questions an inspector would.

Working at height is the single biggest focus area on Danish construction sites. Scaffolding must be erected, altered, and dismantled only by workers with the relevant competency card (stilladscertifikat). Edge protection, guardrails, and toe boards must be in place wherever there is a fall risk. Ladders must be secured and used only for short-duration access, not as permanent workstations. If you find a crew member working above two metres without fall protection, stop the work immediately, this is exactly the kind of violation that leads to an on-the-spot work suspension.

Housekeeping matters more than many foremen realise. A cluttered site with loose cables, uncontrolled material storage, and blocked emergency exits will draw immediate attention. Inspectors interpret poor housekeeping as a sign of a broader safety culture problem, not just a tidy-up issue.

Step 4: Prepare Your Crew for Inspector Contact

Arbejdstilsynet inspectors may speak directly to workers, not just the foreman. They are allowed to do this, and workers have the right to speak to inspectors without the foreman present. This is not a threat, it is a legal protection for workers. However, it does mean that every member of your crew should know the basics: where the APV is kept, who the safety representative is, and what to do in an emergency.

Language can be a genuine barrier. If your crew speaks primarily Polish and the inspector speaks Danish or English, having a bilingual safety briefing document prepared in advance is a practical solution. Arbejdstilsynet does not require documents to be in Danish, but the safety information must be genuinely understood by workers, not just filed away. Consider that if a workplace accident does occur, the question of whether workers were properly informed will be central to any liability assessment. Our article on Workplace Accident in Denmark: Who Is Liable in 2026 explains how that liability is distributed between contractors, subcontractors, and employers of record.

Step 5: Respond Correctly When an Inspection Happens

If Arbejdstilsynet arrives unannounced, which is the norm, stay calm and cooperative. Assign one person, ideally the foreman or a designated safety coordinator, to accompany the inspector throughout the visit. Do not attempt to hide problems or steer the inspector away from certain areas. Inspectors are experienced professionals and such behaviour typically makes things worse.

After the inspection, Arbejdstilsynet will issue a written report. If violations are found, the report will specify a deadline for correction. Take these deadlines seriously. Failure to correct a notified violation within the given timeframe can escalate to a prohibition notice (forbud), which stops work entirely until the issue is resolved. Fines for repeated or serious violations can reach significant amounts under Danish law, and the reputational damage with Danish main contractors can be lasting.

Common Mistakes Polish Foremen Make Before an Inspection

The most frequent errors are not dramatic failures, they are administrative gaps. An APV that was written two years ago and never updated for the current project phase. A new worker who started last week and received no documented induction. A scaffolding structure that was modified by a worker without the correct certificate. These are the issues that inspectors find most often, and they are entirely preventable with a consistent weekly review process.

Pay attention to your tax and social security obligations as well. Polish workers posted to Denmark must be correctly registered, and their employment terms must meet Danish standards. If there are irregularities in how workers are engaged, for instance, false self-employment arrangements, Arbejdstilsynet findings may be shared with Skat (the Danish tax authority) and with Polish institutions including ZUS and PIP.

Actionable Advice: Build a Weekly Safety Routine

The most effective preparation for an Arbejdstilsynet inspection is not a last-minute scramble, it is a consistent weekly habit. Every Monday morning, walk the site before work begins. Check fall protection, equipment certificates, housekeeping, and your documentation folder. Every time a new worker joins the crew, complete and file a written induction record before they start work. Every time a hazardous substance arrives on site, confirm the safety data sheet is present and accessible.

Make the APV a living document, not a filing cabinet trophy. Update it whenever the scope of work changes significantly, when you move from groundworks to structural work, for example, the risk profile of the site changes and the APV should reflect that. Arbejdstilsynet inspectors know what a genuine, actively maintained APV looks like, and they know what a template that nobody has touched in eighteen months looks like too.

Danish construction safety law is demanding, but it is transparent. Everything Arbejdstilsynet expects of you is published, in detail, at at.dk. A foreman who reads that guidance, applies it consistently, and builds a culture where workers feel safe raising concerns is well positioned, not just for the next inspection, but for every project that follows.
