Lesson 5 of 5

Best Inspection Practices

Everything in this module works only if it's done consistently. This closing lesson brings it together into habits, safety rules, and a simple checklist you can put into practice tomorrow.

5.1 Build a proactive culture, not a reactive one

The single biggest difference between plants with low cyclone downtime and plants with frequent surprise failures isn't better equipment — it's inspection discipline. A proactive culture treats daily checks as non-negotiable, keeps to the schedule even when the unit "looks fine," and trusts the data over gut feeling when the two disagree.

Reactive plants only inspect after something has already gone wrong. By then, the cheap, early-stage fix window from Lessons 1 through 4 has already closed.

5.2 Safety comes first

Hydrocyclone inspection often means working around pressurised slurry lines, near rotating pumps, and sometimes inside or beside a vessel that has just been isolated. None of the techniques in this module are worth a shortcut on safety.

Non-negotiables before internal inspection
  • Full lockout/tagout (LOTO) on the feed pump and isolation valves before opening any unit
  • Confined-space procedures if entering the vessel or surrounding pit
  • PPE for slurry residue — gloves, eye protection, and appropriate footwear at minimum
  • Never rely on a "probably empty" line — confirm depressurised and drained before opening

5.3 Common mistakes to avoid

MISTAKE 01

Skipping units that "look fine" — the units that fail unexpectedly are often the ones nobody was watching closely.

MISTAKE 02

Not comparing readings to a baseline — a single number means little without something to measure it against.

MISTAKE 03

Skipping photos — a written note like "some wear" is far weaker evidence than an image months later.

MISTAKE 04

Delaying replacement past the safe threshold — waiting "one more week" is how planned work becomes emergency work.

5.4 A simple SOP checklist

Standardising the sequence — regardless of who's performing the check — keeps quality consistent across shifts and technicians.

  1. 01 Confirm unit ID and pull up its baseline record before starting
  2. 02 Follow LOTO and PPE requirements for the tier of inspection being performed
  3. 03 Complete the checklist for the correct tier (daily / weekly / monthly)
  4. 04 Photograph any finding, however minor it looks
  5. 05 Log the result immediately — not "later in the shift"
  6. 06 Flag any red-flag finding for immediate escalation, per Lesson 3
  7. 07 Confirm the next inspection date is scheduled before closing out
Key Takeaways
  1. Consistency is what makes an inspection program work — a great checklist followed occasionally is worse than a simple one followed every time.
  2. Safety procedures — LOTO, confined space, PPE — are never optional, regardless of how routine the check feels.
  3. The most common failures come from small shortcuts: skipped units, missing baselines, missing photos, and delayed replacements.
  4. A standard sequence, followed by everyone, keeps quality consistent across shifts and removes guesswork from the process.
