Internal Assessment

Cleanliness of tank?

• Was the tank cleaned prior to inspection?

  Yes

  No

• Describe sediment type (fine silt, sand, mud etc)

• Sediment depth (mm)

• Coverage (patchy, floor covered, walls etc.)

• Has the tank been sufficiently cleaned? (i.e. are the walls and floor clean?)

  Yes

  No

• Where required give positions as per a clock face dial with the hatch being at 6 o'clock.
  For condition scoring:
  1. Asset as new
  2. Initial signs of deterioation
  3. Satisfactory (unless in an area of high risk)
  4. Poor/action required (especially in high risk areas)
  5. Urgent action required
  
  For reliability grade:
  1. Never fails
  2. Fails occasionally
  3. Fails regularly
  N/A. Unsure
