Cleaning a water-mix fluid sump
- Never put clean fluid in a dirty sump
- Don't use plain water for washing out. You may de-passivate metal surfaces and increase the corrosion risks
- Prepare a permit to work for any cleaning in potentially confined spaces
- Provide equipment to remove and replace sump fluids with minimum spillage
- Keep absorbent material to hand in case of spillages
- Follow your supplier's guidelines as well as this sheet
- Avoid getting fluid or cleaning agents on skin
- Provide good facilities for washing and eating/drinking refreshments away from the work activity
- Treat all wastes as 'hazardous waste' for recycling or disposal
- Check your supplier's recommendation for dosage levels and circulation times.
- Follow the steps in the flowchart.
Personal protective equipment (PPE)
- Respiratory Protective Equipment (RPE) is required if you are creating a mist, eg when using a high pressure water hose. Provide RPE with a UK Standard Assigned Protection Factor of at least 20, eg FFP3 or powered TH2.
- Provide suitable gloves. Use thicker gloves which provide protection from chemical and mechanical hazards, but only when machinery is switched off.
- 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.
