Guiding Light Signaling Systems Corporation United States Patent 7252401 |

The GLSS is designed with safety in mind. v With numerous ground crew deaths, the GLSS provides an added measure of safety with it's built-in reflective coating. v The GLSS uses AC or DC power to keep the wands ready for nighttime use. v The receptacle provides a standard location to store the wands until the next use. The GLSS addresses the safety concerns noted in the 1996 accident investigation of Marion Taylor, an AMR employee who was "struck and killed by a fuel truck" driven by a fellow employee. The complaint cites the following:
... AMR's employees
wore uniforms consisting of dark blue shirts and blue jeans. In inclement
weather, employees wore standard yellow rain gear (Tr. 52, 61).
None of these garments bore reflective
material (Tr. 52, 62).
AMR employees working for Midway at Hartsfield worked on Concourse D, which at night was lighted on only one side, unlike the other concourses, which were lit on both sides (Tr. 56). The night shift wingwalkers used wands which consisted of flashlights with yellow cone extensions covering the ends. There was undisputed evidence that "with some frequency," these wingwalkers were unable to locate the night wands from the previous shift, or the night wands were found to contain dead batteries (Tr. 52, 54, 62-64). At times when night wands could not be located, day wands were used which did not light up (Tr. 54-55, 63).... For the full report click here: |
