Task Prior to Abatement (Method Which Identified Hazard)

Medical records of back injury cases among delivery workers.

Ergonomic Risk Factor (Repetition)

18 stops a day with 10 to 12 ramp trips per stop, caused great fatigue injury in delivery workers and increased the back injury risk factor.

Ergonomic Solution (Engineering Controls)

Aluminum hand trucks were used instead of steel ones, reducing the total weight per hand truck trip by 7 or 8 pounds, which equates to reducing the weight by more than half a ton on each route.

Ergonomic Solution (Benefits)

Reduced risk factor exposure.

Improving delivery driver productivity and morale.

Ergonomic Solution (Method Which Verified Effectiveness)

Significant decrease in back injury cases among workers using the new aluminum hand trucks.

Comments

While the lighter weight can be beneficial, less weight generally introduces less stability which, in some cases, may cause more musculoskeletal strain as workers struggle to keep their loads steady.
