Start with the conclusion
If you remember one thing, make it this: sort the scene before discussing the plan. Around fault codes this holds in most cases, because many people do the reverse and the gap shows over time. A code is a message, not a verdict, and reading it in context beats guessing from memory.
How to handle it
If a fault code appears, follow three steps: stop using the unit and keep the scene, contact the responsible party, and keep a record. One order must not be broken: write the standard into the process. Skipping the record is how a one-off event becomes a pattern nobody can later explain or defend.
Habits that compound
Small habit tweaks sometimes beat equipment upgrades. Looking before use, confirming after, and stopping on anomaly form a routine that avoids trouble.
