Recent warmer temperatures during the daytime have resulted in melting snow and ice, which then refreezes at night. With more than 400 building entrances on site, it is challenging for snow crews to keep every entrance snow- and ice-free all winter. Employees and users are encouraged to walk more slowly, to take smaller steps and to look closely for snow and ice. Uneven surfaces can complicate matters. Chunks of ice and snow or even coarse rock salt can cause normally smooth surfaces to become uneven. Expect the unexpected, wear footwear that provides traction on snow and ice, and please slow down while traveling around the site.
