Vern Anderson, Ph.D., Coordinator Retail Trades Occupational Health CDC/NIOSH Mike Leiner Manager Store Safety Target Corporation Successful Applications of Ergonomic Principles to Loss Prevention

Two Acknowledgments for Leadership in Safety 1. RILA recently signed a “Letter of Agreement” with the “Centers for Disease Control & Prevention” (CDC) and its Occupational Safety and Health Program CDC/NIOSH). 2. The Loss Prevention Foundation (LPF), known for its Certification and Training for Loss Prevention also signed a “Letter of Agreement” with (CDC/NIOSH). The purpose of both of these Letters of Agreement was to acknowledge the importance of workplace safety and to provide information on safety and health to their membership. In addition, the resources of CDC/NIOSH are committed to these same goals.

Ergonomic is good business! Take Away Message Correlates with business success Adds value- provides competitive edge –Quality, efficiency, profitability –Controls costs (direct and indirect) It’s the right thing to do Protection of our most valuable resource: employees! But, we can do more to protect our employees/customers.

Purpose of our Presentations. We will show through examples how applying ergonomic principles can: - improve productivity -reduce loss of property -reduce loss of work time from preventable accidents

What you may not know about ergonomics. Why be concerned about MMH injuries? Examples of Good Work Practices Example of Ergonomic Solutions Costs and Loss Prevention Goals Matching Solutions to Problems Presentation Outline

Safety Activities: Phases (IAS) –Investigate –collect information –Analyze- assess and plan –Solve- develop solutions: Training: Takes time, re-training needed Administrative: Management decisions Engineering: i.e., Ergonomic solutions Safety and Ergonomics

. Ergonomics is an engineering science to improve work efficiency Ergonomics is about prevention through design. What you may not know about ergonomics.

Ergonomics is about adapting work to fit your workforce: big or small* Ergonomics is about how workers do their job and use tools (Logistics) What you may not know about ergonomics

Put aside the notion that workplace ergonomics is only about injuries Ergonomics makes good business sense: Healthy people work better Sick people perform poorly Ergonomics : Some Facts

Why Address Manual Material Handling?

Some Facts to Consider: (Retail/Wholesale) Affects 8-10% of workers yearly Accounts for 21-36% of workplace injuries Responsible for 33% -60% of workplace injuries costs Because Lifting Injuries are important

They represent the biggest single contributor to worker injury in the United States In short : Lifting Related Injuries...and the application of good ergonomic design and good work practices can substantially reduce those incidences.

Problem: Stocking shelves or a gymnast We can do better

Another Tough Lift: Unloading Boxes We can do better

Problem: All to Common We can do better

What are our Solutions? Manual Materials Handling Jobs Various Solutions: Good Work Practices “Soft Ergonomics” Engineering Changes “Hard Ergonomics”

Ergonomic Study Examples

More Ergonomic Study Example

Ergonomic Study Example Height Adjusted Pallet Jack Used a Height Adjustable Pallet Jack to elevate low boxes on pallet (bottom 1 / 3 ) to waist level when stocking on store floor, thereby reducing back bending & compressive forces on spine when cutting boxes open and lifting from pallets. BEFORE AFTER

Okay, so not everybody gets excited about ergonomics

Tested a spring-loaded customized self-leveling cart to reduce the bending and stooping required to load/unload flat-bed carts and the forces on the back /spine Ergonomic Study Example Self-Leveling Cart Deli/Bakery

Ergonomic Study Example: Results BEFOREAFTER Strong positive usability feedback and highly recommended (2 associates) Back, Shoulder, & Knee discomfort ↓dropped ≥ 30% (2 associates) Productivity ↑increased 1.9% (delivery time) = 5.3 min. savings/day Spring Self leveling cart : Deli/Bakery

Ergonomic Results Example: Deli Bakery BEFOREAFTER Also Positive usability feedback and recommended (1 associate) Reported Low Back discomfort ↓ 29% (1 associate) Productivity ↑ 9.2% (transport time) = 6.2 min. savings/day (1 associate) Tested Battery powered adjustable cart to reduce carrying & Lifting

Findings from Ergonomic Studies Adjustable carts allowed products to be placed at waist level –Reduced -bending down to floor level –More workers were able to do this job –Did not affect productivity Workers liked the cart –Reported less back fatigue –Easy to use - felt to be more productive –Liked cart maneuverability

Sprains/strains–muscles, ligaments, tendons Chronic pain affecting joints Disc injuries of the back or neck Compression of peripheral nerves Soft tissues disorders bruises Compression of blood circulation Injuries from Manual Lifting Tasks 29

What you don’t want. Median number of lost work days –5 days for all workers with any injury –25 days for workers with MSDs Average cost per injury –$1,100 for all other cases –$10,800 for an MSD MSDs tend to have –Longer durations –Longer treatment time –Greater work disability Musculoskeletal Disorders 30
