Guidance Document for Traffic Lane and Personnel Safety Zones 

When longshore workers are working on the “apron or highline” within
the footprint of a shore based container gantry crane adjacent to the
vessel (e.g. coning or signaling), “Traffic Lanes” and “Personnel
Safety Zones” should be marked.  They should be wide enough to provide
protection to longshore workers, accommodate the equipment being used
and in general conform to the following guidance: 

The inside dimension of Traffic Lanes should be wide enough to
accommodate the widest piece of equipment (e.g. bomb carts, straddle
carriers, etc.) expected to be driven within the lane. 

Personnel Safety Zones should be provided on each side of a Traffic
Lane. 

The outside dimension of all Personnel Safety Zones should be wide
enough to position cone boxes and have adequate spacing for longshore
workers to walk around the cone box without stepping into the traffic
lane. 

Provisions should be made to guide the driver so that haulage equipment
does not extend out of the Traffic Lane and so that drivers can align it
under the crane.

Semi Tractors should be driven within the traffic lane so that haulage
equipment does not extend into the Personnel Safety Zone where longshore
workers are positioned.  

Provisions should be made to safely handle specialty or project cargo
which might be transported under the crane on flat beds, “mafis” or
low boys and which may extend into Personnel Safety Zones.  

The traffic pattern under the crane should be well established and known
to the drivers and longshore workers on foot.  Precautions should be
taken if deviations from the traffic pattern must be made (e.g. if
reefers need to be turned or if equipment turnouts are planned.)

Hatch covers should not intrude into Traffic Lanes or Personnel Safety
Zones which are in use.  

If possible, in a bombcart operation, consideration should be made to
move cone bins and coning operations away from the under crane(s)
activity area.  In that event, only traffic lanes need to be referenced
or marked.
