Knife Sharpening
Angled Right Angled LeftStraight
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
• Use good on-line knife sharpeners
• Install these sharpeners correctly
• Properly maintain the honing and/or hollow grinding machine
• Have knife sharpeners learn and use proper sharpening techniques
• Maintain consistent blade shapes
• Inform sharpener of cutting jobs where people are having MSDs
Knife Sharpening Program
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
Knife handles come in a variety of ergonomic designs, including soft grip, non-slip, and angled blades.

Job Enlargement
QuickTime™ and aSorenson Video 3 decompressorare needed to see this picture.
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
• Reduced boredom
• Reduced work stress
• Reduced MSDs
• Reduced turnover
• Reduced absenteeism
Job Rotation Benefits
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
• Workers did not want to change
• Machine operators didn’t want to “lend” to others
• Education and training for new jobs
• Finding appropriate jobs to rotate to
• Used inappropriately by management
Job Rotation Implementation Problems
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
• Reduce number of MSDs
• Reduce rotations that increase stress
• Reduce absenteeism and turnover
• Involve and further educate employees
Job Rotation Goals
ERGONOMICS :: TRAIN-THE-TRAINER PROGRAM :: ERGONOMICS CONTROLS
• Insufficient Data that belts significantly reduce trunk loading
• Insufficient data that wearing reduces risk of injury based on IAP and EMG
• May strain cardiovascular system• Insufficient data that discontinuation of
use increases risk among healthy workers
NIOSH does not recommend as a tool for prevention
Workplace Use of Back BeltsNIOSH 94-122
