7. Control measures — hierarchy of controls

Elimination / substitution: Evaluated where practicable — see Section 12.

Engineering controls:

  • Drip trays under dispensing points
  • Bunded storage

Administrative controls:

  • Avoid skin contact — used oil is a recognised carcinogen (see HSE INDG35)
  • Change contaminated clothing promptly

Personal Protective Equipment (PPE):

  • Nitrile gloves
  • Safety glasses
  • Overalls

8. Storage and handling
Temperature Ambient
Location Dry store, bunded if bulk

  • Safe oil handling
  • Used-oil segregation
  • Skin-care awareness (used oil carcinogen)

13. Assessment outcome

Outcome

User acknowledgement

Reformatted 09/09/2026 to the 16-section COSHH template. Hazard classification, exposure limits, control measures and risk rating are unchanged from Issue 2 — the migration added the persons-at-risk grid, frequency and duration of exposure (COSHH Regulation 6), the GHS pictogram grid, the assessment outcome and the signature block.

This assessment must be reviewed annually or when circumstances change — whichever is sooner.

Method statements

No field method statement calls up this substance.

It is a fleet, plant-maintenance, office or welfare item rather than something used in carrying out a field task. The method statements held on the Van Packs site cover field operations; substances used on the vehicles, in the yard workshop or in the office are controlled by this assessment and by SOP 8.5 alone.

This assessment is one of thirty held under APP_09. The substance-specific controls are above; the system that maintains them is below.

Standard applied: COSHH Regulations 2002 (undated reference), with workplace exposure limits taken from HSE EH40/2005 and hazard classification from GB CLP. Referenced undated so a new edition does not force a re-issue of every assessment.
