10. REMOTE CONTROLLED CRANE UNDER REPAIR.
+
All persons operating other cranes on the same or adjacent runways shall be notified
before anyone boards the subject crane. Such notification should include limitations
of adjacent crane movement while others are on board.
+
PRC cranes, which have been pre-positioned for repairs and cannot be moved should
be protected against being bumped by other cranes on the runway. Suitable bumpers
adequate for the job should be installed on the exposed sides of the crane under repair
and as far away from the crane as possible, with a minimum distance of 20 ft.
(approximately. 6.1 m). The location of these bumpers shall be indicated by red
lights so that they are clearly visible to other persons operating cranes travelling on
the same runway. When it is impossible to use bumpers for protection, red lights
shall be placed in clear view of other persons operating cranes on the same runway to
indicate the restricted travel zone. It is desirable that such red lights be located a
minimum of 20 ft. (approx. 6.1 m) from the crane under repair.
+
All operators of cranes on the same runway must be informed of the repair work,
thoroughly instructed as to what their conduct should be for the duration of said
repairs, and informed when repairs are completed.
+
When there is a runway adjacent to the runway on which the crane is being repaired,
and if any hazard exists involving repairmen, red lights shall be placed in clear view
of persons travelling on the adjacent runway to indicate the restricted travel zone. It
is desirable that such red lights be located a minimum of 20 ft. (approx. 6.1 m) from
the crane under repair. When it is necessary to operate cranes on adjacent runways,
such cranes shall come to a full stop before entering the restricted area. Cranes
traveling on adjacent runways may only proceed through the restricted area when
permission has been received from a signalman posted for this purpose.
+
Access of persons to and from the crane being repaired shall be under the control of
the repair crew leader.
+
The floor area below the point where crane repairs are being made shall be roped off
and posted with danger signs.
+
Handling of all small tools and materials, etc. from ground level to workers above
shall be accomplished through the use of hand lines. Tools, materials, etc. shall not
be tossed from the crane to the ground level and vice versa.
+
If crane repairs make it necessary for crew members to work on areas of the crane
other than those protected by standard handrails, such crew members shall wear
approved safety belts.
