b. Keep tools, stones, and dirt away from the edge of a trench. Excavated material
removed from trenches in streets should be kept on the traffic side of trenches, whenever possible,

c. Carefully refill excavations until such time as permanent paving can be done. See that
all refilling is well tamped.

safeguards over gears, chains, and other moving parts. Do not stand near digging buckets while
the machine is in operation.
e. Protect all open holes along streets and highways or other frequented places by suitable
covers.
f. In excavations which workers may be required to enter, excavated or other material will
be kept at least 0.6 meters (2 feet) or more from the edge of the excavation.
g. When workers are required to be in trenches 1.2 meters (4 feet) deep or more, at least
two separate and adequate means of exit, such as ladders or steps, will be provided and located
requiring no more than 7.5 meters (25 feet) of lateral travel.
h. Sides of trenches 1.5 meters (5 feet) or more in depth will be shored, sloped, or
otherwise adequately supported to protect those working within them.
i. Suitable gloves will be worn when using any equipment or tools to excavate, expose, or
handle direct-burial cables.
