Power presses, robot guarding, assembly ergonomics and OEM supplier social standards — the high-risk operations of an automotive plant are managed with ISO 45001:2018.
The OH&S profile of an automotive supplier is dense: high-tonnage power presses (crushing and amputation risk), welding robots (impact, pinning, entry into the guarded envelope), the assembly line (repetitive strain, awkward postures), paint shops (solvent exposure), compressed-air systems and forklift traffic. The highest fatality risk sits around presses and robotic cells. ISO 45001:2018 provides a single framework to manage this multi-dimensional risk.
European OH&S law sets the floor. The EU Framework Directive (89/391/EEC), the Machinery Directive (2006/42/EC, becoming Regulation 2023/1230), the Work Equipment Directive (2009/104/EC), the Manual Handling Directive (90/269/EEC) and the national OSH acts that implement them place binding duties on the employer for risk assessment, safe work equipment, training, occupational health surveillance and worker consultation. ISO 45001 maps cleanly onto these obligations.
OEM supplier audits take safety seriously. Drive Sustainability (the cross-OEM supplier programme that groups Volkswagen, BMW, Mercedes-Benz, Stellantis, Volvo, Scania and others), Ford Supplier Code of Conduct, Toyota Green Supplier Guidelines and the German Supply Chain Act (LkSG) all include OH&S criteria. Total Recordable Incident Frequency Rate (TRIFR), fatality rate, near-miss reporting and risk-assessment discipline are scored. Poor OH&S performance is a contract-renewal risk.
As suppliers extend toward IATF 16949 and the EV component space, the social and safety expectations tighten. European OEMs increasingly include ISO 45001 (or an equivalent demonstration of an OH&S management system) in supplier qualification, and SMETA/Sedex audits pull in worker-protection evidence directly. The certificate is a competitive advantage today and a de facto requirement tomorrow.
The press is fitted with a two-hand control, but operators have defeated one of the sensors with a weighted fixture, allowing single-hand cycling for "higher throughput". The modification is discovered during the audit. On the next cycle a hand-crush event is credibly possible, and the plant's risk assessment does not reflect the current configuration. Corrective action: remove the fixture immediately, conduct a safety conversation with the operators, add a daily defeat-detection check to every press station and audit the rest of the press area for similar modifications.
The welding-robot cell is guarded by a light curtain that works correctly in normal operation. However, during maintenance and fault recovery technicians routinely step past the curtain while the robot is energised. A written LOTO procedure exists, but a "maintenance is quick, LOTO wastes time" culture has taken over. Near-misses in the last eight months are documented; no corrective action has been taken. Corrective action: re-train on LOTO, install a key-interlock system, make a locked gate the physical precondition for entry, and perform root-cause analysis on the existing near-misses.
Occupational-health records show a rising trend of lower-back complaints on the final assembly line — four workers took sick leave for physical therapy from the same station in the last twelve months. The ergonomic risk assessment for that station has not been revised in three years, and the trend has not been carried into the assessment as an input. Complaints are still treated as individual cases. Corrective action: run a full RULA/REBA (or EAWS) assessment on all assembly stations, correlate the lower-back trend with station scores, and launch ergonomic improvements at the worst-scoring stations.

For high-tonnage presses two-hand control systems are typically mandatory under the EU Machinery Directive (2006/42/EC) and harmonised standards such as EN 692 (mechanical presses) and EN 693 (hydraulic presses). For lower-tonnage presses alternative safeguards (light curtains, tunnel guards) can be accepted. The choice is driven by a documented risk assessment based on tonnage, operating cycle and part geometry.
When the robot cell is entered for maintenance or fault recovery, energy must be isolated: the main disconnect is switched off, pneumatics and hydraulics are bled and locked, and each technician attaches a personal lock and tag. Light curtains and interlocked gates remain active; where more than one person can be inside, a key-interlock or group-lock system is used. Bypassing LOTO to keep the line running is the single biggest cause of fatal robot-cell incidents.
Line stations are analysed with methods such as ISO 11228 (manual handling), RULA, REBA, OCRA and EAWS (the Ergonomic Assessment Work Sheet used widely by European OEMs). Repetitive motion, lifted weight, awkward postures and out-of-envelope work heights are scored. Occupational health complaints for lower back and upper limbs are correlated with station data, and high-score stations are prioritised for lifts, tilt tables and part presenters.
