Foreseeable Misuse
In the context of EU compliance, "Foreseeable Misuse" is a critical concept that often surprises North American manufacturers. unlike US product liability, where "user error" can sometimes be a defense, EU law mandates that you design your machine to account for predictable bad behavior. You cannot simply blame the operator; you must anticipate how they might instinctively react or cut corners.
Common examples in industrial settings include an operator reaching into a press to catch a falling part (reflex action), using a machine frame as a ladder to change a lightbulb, or bypassing a safety interlock to clear a jam faster. Under the Machinery Regulation, you are legally required to identify these scenarios during your Risk Assessment.
Your Technical File must demonstrate that you have applied Risk Mitigation Measures to prevent this misuse. The hierarchy is strict: you must first design the hazard out (e.g., make the jam impossible), then guard against it (e.g., non-bypassable interlocks), and only as a last resort rely on warnings in the manual.
