SCANNER SAFETY AND LOCAL CONTROLS
When the scanner is raised or spans open floor areas, fall protection needs to be
considered in accordance with local mill rules and regulations.
Table 1 lists and describes hazard zones.
Table. 1. Scanner Frame: Mechanical Motion Precautions
Work in this area has dangerous pinch points
associated with pulleys, belts and moving
carriage parts which can cause serious injury.
Work in this area requires lockout/tagout of motor
drive or higher electrical circuit.
This area has the potential for body crush
between moving heads and end support.
Buffer stops are set at factory to provide 0.5 m
(19.7 in) safety clearance.
Work in this area requires lockout/tagout of motor
drive or higher electrical circuit.
Work in this area has potential for impact from
moving heads. Pinning of worker between
heads and other close mill equipment is also a
concern.
Work in this area requires lockout/tagout of motor
drive or higher electrical circuit.
Typically, work done at heights > 3 m (9.84 ft),
or above dangerous equipment require use of
a fall protection system. Use caution when
working on elevated scanners or spans over
open floor sections.
Refer to local mill safety rules for use of ladder and
worker height restrictions with or without fall
protection system. Typical systems include fall
arrest harnesses, and anchors or fall restraint
systems.
Figure 6 through to Figure 10 shows a variety of pinch point locations.
