G4−2: Reducing Worker Exposure by Using Quick Change Sign Post
A pre−cast concrete base with metal sleeve is placed in an augured hole, leveled, backfilled, and compacted. The signpost is placed into the metal sleeve and held in place by two rubber wedges. When the sign is hit, the rubber wedges are popped out, a new signpost replaces broken post, and rubber wedges are replaced. This practice is currently implemented as signs in high hit locations are damaged.
REASON(S) FOR ADOPTING:
The California Department of Transportation (Caltrans) has had an increased awareness of worker exposure and was looking at ways to improve safety and reduce worker exposure.
Reduced worker exposure in high hit locations. A maintenance operation that otherwise might have taken hours to replace the sign posts, now takes minutes and requires less equipment and workers.
MOST APPLICABLE LOCATION(S)/PROJECT(S):
Quick change sign posts are currently being implemented at locations where signs are routinely hit and require frequent replacement.
