Modified Floor Scraper

Task
Scraping gum off the floor is a task performed daily by custodians at this hospital.

Problem
Sustained forward-bending when scraping chewing gum from floor of building lobby. This led to frequent complaints of lower back pain among custodial staff, who were bent forward up to 90 degrees at the waist, and flexed the shoulder up to 90 degrees, along with neck extension and ulnar deviation of the wrist while using the hand-held scraper. No workers compensation claims had been filed.

Intervention
The scraper blade was removed from the handle and attached to an old broomstick. A foam grip was added at the top of the handle.

Cost
Less than $10.00
