Public Works employees have long sought a safety cage <br />surrounding the ladder, which would bring the ladder up to today's OSHA standards, <br /> <br />e <br /> <br />Ladder Ca!!e Costs <br />AEC estimates it would cost $7,000 to install a steel safety cage around the ladder that <br />climbers could lean back and rest against.
