When a stop occurs: (1) Record stop time, alarm code, and bottle count produced before the stop \u2014 establishing the &#8220;pre-stop&#8221; lot boundary; (2) Record post-restart first-article qualification results and the bottle count at which compliant production resumes \u2014 establishing the &#8220;post-restart&#8221; boundary; (3) Quarantine all bottles produced between pre-stop and post-restart boundaries, including purge shots; (4) If the stop lasted longer than 15 minutes, a &#8220;process deviation report&#8221; is required documenting cause, duration, and corrective action \u2014 this report becomes part of the GMP lot release certificate.

Korean ISBM operations with operators averaging more than 2 years platform-specific experience consistently achieve 8\u201315 percentage points higher OEE than operations with predominantly new operators. An experienced operator who has seen a specific alarm code 20 times knows within 60 seconds whether the stop requires a 5-minute reset-and-monitor response or a 45-minute mechanical inspection \u2014 the same determination takes a new operator 15\u201330 minutes.

The five most common operator-caused problems, in frequency order: (1) <strong>Wrong recipe loaded<\/strong> \u2014 operator loads previous production&#8217;s recipe without checking against production order. Prevention: recipe verification is check #1 on the pre-shift checklist. (2) <strong>Resin hopper run empty<\/strong> \u2014 barrel runs dry mid-shift, producing a sequence of short-shots that jam in the conditioning station. Prevention: hopper level check in shift handover. (3) <strong>Masterbatch doser not loaded at shift changeover<\/strong> \u2014 first 200\u2013300 shots of incoming shift are uncoloured before quality check catches it. Prevention: masterbatch doser level is a required handover data field. (4) <strong>Cooling water isolation valve left closed after maintenance<\/strong> \u2014 mould overheating takes 15\u201325 minutes to manifest as bottle deformation. Prevention: cooling water isolation valve position is a pre-shift visual check item. (5) <strong>Blow pressure setpoint inadvertently adjusted<\/strong> \u2014 operator attempts to resolve a quality issue unilaterally without process technician authorisation.
