Title: Nickel Risk Assessment The impact on Plating Activities


1
Nickel Risk AssessmentThe impact on Plating
Activities
  • To what level of operation will this impact on
    the business of
  • Nickel Plating

2
Nickel Risk AssessmentThe impact on Plating
Activities
  • The effects of the current and proposed
    legislation on the day to day operation of a
    Nickel plating facility.
  • Either Rack, Barrel or processes
  • Equally applicable to -
  • Bright Nickel
  • Semi Bright Nickel
  • Micro porous Nickel
  • Satin Nickel
  • Electroless nickel

3
Nickel Risk AssessmentThe impact on Plating
Activities
  • Exposure at tank side during plating
  • Lip Extraction
  • Agitation
  • Air or Pumped
  • Splashing during draining

4
Nickel Risk AssessmentThe impact on Plating
Activities
  • This leads onto the problems associated with
    keeping the extraction system clean and
    functioning.
  • With salts precipitating out the cleaning process
    is laborious, but steam cleaning with the high
    risk of aerosols is now going to be a significant
    problem.

5
Nickel Risk AssessmentThe impact on Plating
Activities
  • Solution make up
  • Handling chemical solids
  • High inhalation of dust risk
  • Weighing out
  • Adding to tank
  • Skin contact when handling chemicals
  • Eco rinse cycle
  • Clean up drag out and use as top up
  • Use liquid additions
  • pH control splashing concerns

6
Nickel Risk AssessmentThe impact on Plating
Activities
  • Filter maintenance
  • Minimal dust/solids issues
  • High risk of aerosols when venting filter
  • Splash problems when removing or inserting
    cartridges
  • Cleaning of reusable cartridges will produce more
    nickel contaminated solution

7
Nickel Risk AssessmentThe impact on Plating
Activities
  • Pellet additions to cages
  • Aerosol or splash risk during this operation,
    small but sufficient to warrant review of how
    this process is carried out.

8
Nickel Risk AssessmentThe impact on Plating
Activities
  • Anode maintenance
  • Leave bags to drain over tank
  • Beware if they dry out additional dust risk
  • Bag removal is high contact risk if still wet
  • Anode cages once exposed need to be cleaned, if
    pellets removed difficult to clean and save for
    re use.
  • Steam clean in cage, high risk of inhalation
  • Splashes and aerosol risk when removing
  • Immersion of bare cage produces handling issues
  • All processes generate contaminated liquid

9
Nickel Risk AssessmentThe impact on Plating
Activities
  • Tank emptying and refilling
  • Control of discharge
  • Removal of last liquids
  • Clean down prior to entry
  • Return of solution

10
Nickel Risk AssessmentThe impact on Plating
Activities
  • Tank Top Cleaning
  • Removal of salt build up by any means will pose a
    risk
  • Steam cleaning
  • Hand brushing
  • Air line
  • Hot water washing

11
Nickel Risk AssessmentThe impact on Plating
Activities
  • Laboratory Functions
  • Hull cell testing
  • Wet analysis
  • Density checks

12
Nickel Risk AssessmentThe impact on Plating
Activities
  • Maintenance
  • Even if operators are fully aware of the new
    issues, the maintenance staff may not be.
  • Make arrangements for all equipment removed for
    repair are fully cleaned.
  • If working tank side ensure area cleaned prior to
    work starting.

13
Nickel Risk AssessmentThe impact on Plating
Activities
  • Spill Handling procedures
  • Remember that once the daily operation and
    maintenance activities have been considered there
    is always the unforeseen occurrence that needs
    dealing with in a safe manner.
