Latest HSE guidance in 5 simple steps

The guidance objective is to ensure MWFs are effectively managed to minimise risk of occupational health issues in the workplace

STEP 1

Guidance emphasises the legal requirements under COSHH legislation for employers to conduct risk assessments including reducing exposure and good fluid management application processes

  • All records of fluid analysis to be kept for at least 5 years
  • All records of exposure to Hazardous Chemicals and employee health records to be kept for 40 years
  • Prevention of skin contact and dermatitis by use of suitable PPE
  • Prevention of serious health issues by reducing exposure and other control measures eg; LEV, mist monitoring and mist generation

 

STEP 2

MWF storage in compliance with the Oil Storage Regulations MWF mixing – Recommends use of mixer units and good quality water supply

  • Store product in a dry bunded area
  • Use industry recognised mixing equipment
  • Install water treatment equipment to improve quality where required

 

STEP 3

Guidance outlines the main reasons for maintaining MWFs and the specific areas for control

  • Concentration – check at least WEEKLY
  • pH – check at least WEEKLY
  • Tramp oil – check at least WEEKLY. Recommended max limit of 2%
  • Swarf/fines – Risk assessed based on machining process and keeping to a minimum
  • Dissolved metals – to be monitored and controlled as per EH40 listing
  • Bacteria – Check at least weekly (unless data can justify longer testing regime). New Level for action is now >10⁴ CFUs. Biocide use to be a last resort. Emphasis on good fluid management and regime
    of system cleaning (with system cleaner)
  • Temperature – check WEEKLY

 

STEP 4

Guidance emphasises control of MWF mists by

  • Reviewing products, processes, use of LEV, use of suitable PPE
  • No maximum for exposure has been set however levels to be controlled as low as is reasonably practical, including employee health monitoring
  • Initiating effective maintenance programmes for LEV systems – at least every 14 months

 

STEP 5

Guidance emphasises correct system cleaning with a suitable system cleaner. Guidance advises on correct segregation, storage and disposal of waste MWF
