A pipefitter is asked to work from the top cap of a 6-foot stepladder to tighten a hanger nut. The nut is just out of reach from the highest allowed step.
Stand on the top cap only while another worker holds the ladder.
Turn the stepladder sideways and lean it like an extension ladder.
Stop and get a taller ladder or approved platform so the top cap is not used as a step.
Climb one step lower and overreach carefully to finish the nut.
