Foot Wedged in Toe Space

|
EV was standing at the checkout counter of Gerry's Automotive Supplies.
She leaned over the counter to write a check for the item she was
purchasing. Her husband was near the door, and was motioning for
her to hurry. It was getting dark and he needed to get back to his
truck, which had stalled. When the transaction was completed, the
clerk placed the item in a bag and handed it to EV. She turned to
her right, took one step, and fell onto the floor. EV looked back
and saw that the laminate on the side of the counter near the toe
space was cracked and loose.
HF Issue: Did the toe space provide adequate foot clearance?
If not, could Gerry's Automotive have identified that there was
a problem with the dimensions of the toe space and have taken reasonable
precautions to prevent such an accident.
|
|
HF Investigation: Information collected included, but was
not limited to: EV's height and weight; the dimensions of the shoes
that she was wearing at the time of the accident; the dimensions
of the toe space; and photographs of wear patterns on the floor
and on the side of the counter.
|
|
| HF Analysis: EV's left
shoe was scanned and incorporated into a computer graphic that showed
the clearances between and the shoe and the toe space. |
|
Engineering anthropometry methods were used to determine minimum
toe space dimensions that would provide adequate clearances for
99 percent of the population.
|
 |
| The computed dimensions were
then compared to the toe space dimensions specified in various authoritative
sources. A 3D computer model of EV and the counter was developed to
illustrate the likely sequence of events resulting in her fall. |
|
This case went to trial. The attorney had a model of the toe space
constructed out of Plexiglas in order to demonstrate how EV's foot
likely became momentarily wedged in the space.
