Project – Valve Replacements
Problem:
Process valves used by employees have known associated risks factors when opening and closing
Solution:
•Replace valve with larger handles and/or replace with different type of valves to reduce risk factors
•Continuous improvement initiative
![Page 22: Wednesday, October 14, 2015 Porcupine North-Eastern Ontario Mine Safety Group Conference (PNOMSG)](https://reader035.vdocuments.mx/reader035/viewer/2022062309/56649eb75503460f94bc140d/html5/thumbnails/22.jpg)
22
Project – Valve Replacements
Problem:
Process Operator opens Tomlinson Valves to drain pumpboxes. Valve located in poor location under pumpbox requiring operators to exert force in awkward postures
Solution:
•Relocate existing valves to the sides of pumpbox
•New pumpbox installations have location included in the design
![Page 23: Wednesday, October 14, 2015 Porcupine North-Eastern Ontario Mine Safety Group Conference (PNOMSG)](https://reader035.vdocuments.mx/reader035/viewer/2022062309/56649eb75503460f94bc140d/html5/thumbnails/23.jpg)
23
Project – Cyclone Replacement
Problem:
Cramped space and poor design for inspections and sampling of Cyclones
Solution:
•Enlarged catwalk design and removal of tripping hazards
•Easier access to cyclone overflow and underflow sampling ports and inspections
![Page 24: Wednesday, October 14, 2015 Porcupine North-Eastern Ontario Mine Safety Group Conference (PNOMSG)](https://reader035.vdocuments.mx/reader035/viewer/2022062309/56649eb75503460f94bc140d/html5/thumbnails/24.jpg)
24
Project – Dryer Hopper Hammers
Problem:
Dewatering Operator bangs chutes every 3 hours with heavy sledge hammer exerting excessive force and awkward posture
Solution:
•Install hopper hammers on Cu1, Cu2, Zn1 and Zn2 dryers
• These hammers will help to dislodge the concentrate that builds-up in the chute walls
![Page 25: Wednesday, October 14, 2015 Porcupine North-Eastern Ontario Mine Safety Group Conference (PNOMSG)](https://reader035.vdocuments.mx/reader035/viewer/2022062309/56649eb75503460f94bc140d/html5/thumbnails/25.jpg)
25
Project – Workstation Seating
Problem:
•Loco Operator complaining of sore back and legs falling asleep on Loco’s 054 and 055
•Chair not equipped with proper hardware (foot pedal) creating height problem. Operators compensate by leaning forward at lowest setting to reach pedal, causing discomfort and awkward sitting posture over course of 8 hour shift
Solution:
•Installation of “Industry Standard” and ergo seating for operators with proper hardware
•Change process plant control room seating (Ergo and CSA Standards)
