Be aware that routine activities that seem harmless can actually be hazardous.

An out-of-service floor scrubber was being relocated from the second floor to the first floor via elevator. Using a fork truck, the floor scrubber was loaded onto the elevator on the second floor. After the elevator reached the first floor, the employee used a fork truck to remove the floor scrubber from the elevator. After moving back several feet, the employee identified that the scrubber was unstable (wobbling), so he lowered the floor scrubber to the floor. When lowered, the upper plastic cover and side panel on the floor scrubber came free. This resulted in the scrubbers two lead acid batteries (which were not strapped in place) to break free and fall to the floor. One of the refill caps on one battery came off, spilling acid to the floor.
