FUGUAI = DEVIATION<->ABNORMALITY
- Functional Defects
- Pollution
- Difficult to Access/Observe
- Hard to Load/Operate
- Unsafe
- Safety, Health, Environment, Quality (SHEQ) “unfriendly”
- Undesirable Tasks
“F” Tags are used to highlight Deviations, Faults or Abnormalities.
3 Types of F-Tags
Safety
Safety F-Tags are written by everyone for everyone. Mechanics or operators can close these. Yellow color.
Operator
- Operator F-Tags are Blue.
- Operator means anyone non-maintenance (ie. Operators, Supervisors, Cleaners, Sanitation, etc.) to fix the abnormality.
Maintenance
- Maintenance F-Tags are Red.
- These F-Tags require Electricians, Mechanics, etc. to fix the abnormality.
F-Tagging
- F-Tag (is a visual work order) is a tag that is used to identify problems with the machines
“Four Lists” are used to track the F-Tags:
- Abnormality List
- F-Tag Tally Sheet
- SOC (Sources of Contamination) List
- HTA (Hard-to-Access) List
Where Are Abnormalities Found? Typical F-Tags
- Broken Parts
- Wear, Play, Rattling
- Dust, Dirt, Corrosion
- Cracks, drip marks,
- Deformation, Surface Damage
- Noisy, Hot, Cold, Odour etc…
F-Tag Tracking
- To track the F-Tags we write as part of AM activities, the team will create an Activity Board called the F-Tag Tracking Centre
- This board will show the “Three Lists”, and keep track of how many F-Tags are written and how many have been completed
- The next page shows an example of an F-Tag Tracking Centre
Can you please explain what are the these steps 1-2-3-4-5-6-7 on tag?
Assuming that you are referring to 7 steps of Autonomous Maintenance, f-tag are used through all steps from the moment it would be implemented during step 1.

Tagging is a process of identifying issues (defects), while doing cleaning and or inspections, as well while running equipment, and not related to a particular step of AM. It is a visual tool, that helps to see if equipment has any issues that needs to be resolved.
