DENVER -- Some 80 U.S. postal workers have reported injuries in the Colorado/Wyoming area since the start of the blizzard five weeks ago and the several snowstorms that followed.

A spokesman for the U.S. postal service, Al DeSerro, said the injuries have included fractures, sprains and a concussion due to slips and falls on the ice.

DeSerro said workers were injured in over 30 vehicle accidents with postal trucks, though most of them happened at low speeds.

He reminded residents to keep walkways and access to mailboxes clear of snow to help the postal workers deliver mail safely.
