Safety Operating Procedures for Electroplating Equipment

 

1. Personal Protective Equipment (PPE) Requirements

• Essential Gear:

  • Chemical-resistant gloves (nitrile/neoprene)

  • Splash-proof goggles or face shield

  • Acid/alkali-resistant apron or full-body suit

  • Steel-toe rubber boots

• Respiratory Protection:

  • Use NIOSH-approved respirators when handling toxic fumes (e.g., cyanide, chromic acid)

  • Ensure proper ventilation (minimum 100 CFM airflow)

 

2. Pre-Operation Checks

• Equipment Inspection:

  • Verify intact tank linings and leak-free plumbing

  • Confirm emergency shower/eyewash functionality

  • Check rectifier grounding (resistance <1 ohm)

• Chemical Preparation:

  • Always add acids to water (never reverse)

  • Label all secondary containers with contents and hazards

 

3. Operational Safety Protocols

• Electrical Safety:

  • De-energize equipment before servicing (Lockout/Tagout)

  • Maintain 36" clearance around rectifiers

• Process Controls:

  • Never exceed 80% of tank rated capacity

  • Maintain solution temperatures below 50°C (122°F) unless specified

 

4. Hazard-Specific Precautions

• Cyanide Baths:

  • Store separately from acids (minimum 10ft distance)

  • Implement cyanide antidote kit (amyl nitrite) in work area

• Hexavalent Chrome:

  • Install local exhaust ventilation (0.5m/s capture velocity)

  • Conduct quarterly urine biomonitoring for workers

 

5. Emergency Response

• Chemical Spills:

  • Neutralize acids with sodium bicarbonate, bases with citric acid

  • Use spill kits with pH-neutralizing polymers

• First Aid Measures:

  • Skin contact: Flush 15 minutes (tepid water, 20-37°C)

  • Eye exposure: Irrigate using ANSI-compliant eyewash for 20 minutes

 

6. Post-Operation Procedures

• Waste Management:

  • Segregate acid/alkali wastes for neutralization

  • Label hazardous waste per EPA/DOT regulations

• Housekeeping:

  • Conduct lead wipe tests (surfaces <10μg/ft²)

  • Implement 5S methodology for tool organization

 

Note: All personnel must complete annual 8-hour HAZWOPER training with hands-on drills.
