Europe's Machine Guarding Rules Get a Hard Deadline: January 19, 2027

Crush points and shear lines on industrial machinery are among the most unforgiving hazards a machine operator can face. Preventing serious workplace injuries at those spots depends heavily on contact-sensitive safety devices — and the technical and legal framework around them is about to shift.
A specialist article on machine safety dated 27 October 2026 sets out how these systems work and what employers must prepare for. At the heart of the technology is the tried-and-tested normally-closed principle: during normal operation, a quiescent current flows through a closed contact circuit. The moment someone touches the strip, the contact opens and the machine control brings the dangerous movement to an immediate stop.
Two ways to wire a safety strip
How a switching strip is built determines how it connects to the control system. Versions with an integrated terminating resistor need a separate evaluation unit to monitor them. Strips fitted with a plain normally-closed contact, by contrast, can be wired straight into an existing emergency-stop module.
Linear hazard points are only part of the picture. Larger surrounding zones often need protection too, which is where safety mats come in, safeguarding floor areas in front of installations. Typical applications for these area guards include machining centres, presses, industrial robots and aisles in storage facilities.
Guarding machinery against crush and shear hazards is only half the job — employers also have to prove the risks were assessed and the controls documented.

Standards, statutes and a looming cut-off date
Safety classification of contact sensor technology is governed by DIN EN ISO 13849-1. Assessment runs through defined categories and the required safety integrity level, expressed as the so-called Performance Level.
On the legal side, the European single market is in a transition phase. The EU Machinery Directive 2006/42/EG remains in force until 19 January 2027. After that date, Regulation (EU) 2023/1230 applies bindingly.
At company level, employers must carry out risk assessments for work equipment under the Operational Safety Ordinance (Betriebssicherheitsverordnung) and document them in line with Paragrafen 5 and 6 of the Occupational Safety and Health Act (Arbeitsschutzgesetz). Templates can help, but they have to be adapted to the conditions in each business. Manufacturers also take account of rules such as the Low Voltage Directive 2006/95/EG, the Pressure Equipment Directive 97/23/EG and the Electromagnetic Compatibility Directive 2004/108/EG when designing machinery.
What the warning labels actually mean
Alongside separating and non-separating protective devices, visual marking plays a significant role. Requirements from the US Occupational Safety and Health Administration (OSHA) set a fixed signal-word hierarchy:
- Danger marks immediately hazardous situations that can lead to death or serious injury.
- Warning points to potentially hazardous situations that can likewise have fatal or serious consequences.
- Caution flags potential hazards carrying the risk of minor or moderate injury.
- Notice covers practices for protecting against property and equipment damage with no personal injury.
Operators are expected to check these markings before starting work, report damage without delay and stop work if anything is unclear. For further labelling, requirements call for hazard areas to be recorded in a risk register and visually demarcated with markings, safety signs and signal barriers.
Lockout, tagout and a dedicated watch
Equipment such as mixing machines must be brought to a completely de-energised state before cleaning and maintenance. Procedures are prescribed for isolating the main switch and the maintenance motor's power contactor, including physical locking and warning signs.
Emergency-stop buttons must also be pressed, the operator key kept by maintenance staff or supervisors, and connected conveyor belts shut down on both sides. A dedicated supervisor is required during the maintenance work, and maintenance doors must stay fully open.
Other machining methods carry their own risks. With hand-held laser machines — open laser setups and hand-guided laser welding devices — hazards to eyes and skin are frequently underestimated in practice.
On protective clothing, the Wood and Metal Trade Association (Berufsgenossenschaft Holz und Metall) recommends exhausting technical and organisational measures first. For tasks such as drilling, close-fitting clothing is required, while gloves are banned because of the risk of being drawn in by rotating machine parts.
From lockout procedures to PPE rules, every control you put in place rests on a documented risk assessment — and inspectors will ask to see it.
