Cleaning a heavily contaminated neat oil sump
- Prepare a permit to work for any cleaning in potentially confined spaces.
- Provide equipment to remove and replace sump oils with minimum spillage.
- Keep absorbent material to hand in case of spillages.
- Never put clean oil in a dirty sump.
- Follow your supplier’s guidelines as well as this sheet.
- Tell workers to avoid getting oil or cleaning agents on their skin.
- Treat all wastes as 'hazardous waste' for recycling or disposal.
- Check your supplier’s recommendation for dosage levels and circulation times. Mark these in the gaps provided:
- Sump oil: amount to drain = ___% by volume (__ litres).
- Circulation time = __ hours.
- Second circulation time = __ hours.
- Follow the steps in the flow chart.

- Provide good facilities for washing and eating/drinking refreshments away from the work activity.
Personal protective equipment (PPE)
- Use 0.4mm nitrile gloves to EN 374 standard to provide protection against skin contact with fluids up to 8 hours; these gloves are normally thin enough to provide finger dexterity. Use thicker gloves to EN 374 and EN 388 standards when protection is also required against abrasions and sharp edges.
- Ensure workers discard gloves that are damaged, and at the end of a cleaning session.
- Provide eye protection to EN 166 standard where there is a risk of splashing.
- Workers also need overalls.
- Ensure contaminated overalls are laundered before re-use.
- Provide storage for PPE to prevent damage or contamination when not in use.
- "Barrier creams" do not create a barrier but skin creams can help in washing contamination from the skin. Use a moisturising cream each time you wash your hands and use after-work creams to help replace skin oils.
