  2. JM Melting Operations • Gas-Oxy • Gas-Oxy w/ Electric Boost • SORG Technology • Modified Pochet-Style All-Electric Melters • All-Electric Forehearths Glenn Aspholm

  3. Additional Risks For Pochet Melters • Open Glass Streams • Operator Close to Melter – Open Glass Surface • Required to Probe Glass • Melter Level Measurement • Ladle-Check Glass Flow Measurements • Equipment Change and Maintenance Glenn Aspholm

  4. Additional Risks For Electric Forehearths • Infrequent Glass Level Measurement • Level-Gauge Calibration • Level-Gauge Failure • Upset Condition / Verification • Thermocouple Change • Low – Maintenance, Trouble-Free Operation • Forget the Risks !!! Glenn Aspholm

  5. In-Scope • General Operator Duties • Glass Level Measurement (Melter) • Glass Level Measurement (Forehearth) • Glass Pull Rate Measurement (Ladle Checks) • Thermocouple Change - Forehearth Glenn Aspholm

  6. Out-Of-Scope • Electrical / Mechanical Maintenance • High-Voltage / Low-Voltage Electrical Work • Emergency Conditions • If in doubt, Lock it Out !!!! • Not a replacement for proper Lock-out/Tag-out Procedures Glenn Aspholm

  7. Melter Level Measurement Glenn Aspholm

  8. Open Glass Stream Glenn Aspholm

  9. Electric Forehearth Glenn Aspholm

  10. Risks Around Electric Melters/Forehearths • Thermal (Burn) • Abrasion (Cut / Scrape) • Contact with Molten Glass • Low Voltage Electrical • High Voltage Electrical Glenn Aspholm

  11. Melter and Forehearth Electrical Potential • Melter - < 100 V AC • Forehearth - 50 – 100 V AC Glenn Aspholm

  12. Burn / Abrasion PPE • Bump Caps / Hard Hats • Proper Clothing • Leather Gloves • High – Temperature Clothing and Gloves • Head Protection and Faceshield Glenn Aspholm

  13. Low Voltage Electrical Shock Risks • Electrical Shock – Injury / Death • Secondary Injury – Reaction from Electric Shock • Fall • Burn • Head Injury • Laceration/Abrasion/Fracture Glenn Aspholm

  14. New Requirement - Use of Linesman’s Gloves and Protectors for Normal Operator Functions Glenn Aspholm

  15. Available Linesman’s Gloves Glenn Aspholm

  16. Lineman’s Glove Info • Di-Electric Rubber Construction • Seamless • ASTM D120 Specification • Must be tested and certified every 6 months Glenn Aspholm

  17. Current Specified Equipment • 00 Linesman’s Gloves • Leather Protectors • Order proper sizes – Probably oversized • Cost - Approx $75/set (Glove + Protectors) • 6-Month Certification Required • Pay Certification cost • Replace after 6 months • Source of Information - McMaster-Carr Catalog Glenn Aspholm
