back of mills having a 46 inch roll height or over
- – Operate readily on contact from
the pressure of the mill operator’s body
- Safety trip rods that are:
- – Installed in the front and back
of each mill and located within 2 inches of the front and
rear rolls

no more than 72 inches above the level where the operator
stands
- – Easy to
reach and operate when the rods are pushed or pulled
- Safety tripwire cables or wire center cords
that are:
- – Installed in the front and back
of each mill

more than 72 inches above the level where the operator stands
- – Easy to operate whether pushed
or pulled
2) Make sure that all auxiliary equipment
such as mill dividers, support bars, spray pipes, feed conveyors,
and strip knives don't interfere with safety devices
