lift truck so that the load is on the upgrade side<br />
and cannot slip off the forks.<br />
C. Work Practices<br />
Do not tow more than three empty or loaded containers<br />
of rolling stock (platform trucks, hampers, or containers);<br />
however, driverless tractor units are<br />
permitted to tow up to five containers empty or<br />
loaded.<br />
Do not obstruct aisles, passageways, fire-fighting<br />
equipment, electrical panels, exits, or towveyor lines<br />
with parked, in-plant powered vehicles.<br />
Fully lower the load-engaging mechanism, with controls<br />
in neutral and the brakes set, when the driver<br />
has dismounted and is within 25 feet of vehicle and<br />
the vehicle is still in view.<br />
If the driver is more than 25 feet away from the vehicle<br />
that remains in view, or if the vehicle is not in the<br />
driver’s view, consider the vehicle unattended.<br />
When vehicles are to be left unattended, lower the<br />
load-engaging mechanism, put all controls in neutral,<br />
shut off the power, set the brakes, and remove the<br />
ignition key.<br />
Inspect trailers and trucks that are entered by in-plant<br />
powered vehicles or conveyors to ensure that the<br />
flooring appears capable of handling the load and<br />
that the trailer is prevented from rolling by wheel<br />
chocks or positive-locking parking devices.<br />
Inspect dock plates to ensure that they are capable of<br />
handling the load and are properly seated on the bed<br />
of the truck.<br />
Use the proper hooks and coupling devices for towing.<br />
Do not use your hand to hold equipment being<br />
towed.<br />
Never use propane-powered equipment in poorly<br />
ventilated spaces, such as in a trailer.<br />
D. Maintenance<br />
Repair trucks only if you are authorized to do so.<br />
(Only authorized modifications are to be installed in<br />
powered industrial equipment.)<br />
Disconnect the batteries of in-plant powered trucks<br />
before performing corrective maintenance on them.<br />
Follow appropriate lockout procedures (see Section<br />
XIX, Hazardous Energy Control Procedures — Lockout).<br />
Do not get under a lift truck to do repairs unless it is<br />
properly held up by jack stands.<br />
Remove from service any power-operated industrial<br />
truck not in safe operating condition.<br />
Examine powered industrial trucks before placing in<br />
service and do not place them in service if the examination<br />
shows any condition adversely affecting<br />
the safety of the truck.<br />
E. Special PIT Operating Rules —12 Foot Aisle<br />
Facilities<br />

A maximum of seven general purpose mail containers<br />
(GPMCs) and/or Eastern Region mail containers (ERMCs)<br />
may be towed at any given time provided that the following<br />
criteria are met:<br />
All aisles are clearly marked.<br />
The aisle width must be a minimum of 12 feet to allow<br />
two-way traffic to pass; any aisle less than 12 feet<br />
wide requires one-way traffic or no passing of container<br />
trains.<br />
All 90-degree intersections are required to be chamfered<br />
by 4 feet at a minimum (see below).<br />
Chamfered Intersection<br />
All L&DC and PMPC sites are required to purchase<br />
and install Electronic Speed Control (ESC) Programmers<br />
on all existing PIT vehicles before instituting an<br />
increase of towing more than three mail containers<br />
within the facility. The ESC setting is to be adjusted to<br />
approximately 80%, not exceeding 5 mph with the<br />
Powered Industrial Vehicle (PIV).<br />
All newly purchased PIVs must have the ESC devices<br />
installed by the manufacturer according to the<br />
specifications mentioned above.<br />
When towing more than three GPMC and/or ERMC containers<br />
at one time, the PIT operator must place a folding<br />
tow bar (shown below) between the third and fourth container.<br />
When towing a train of seven containers at one time,<br />
the PIT operator must use two folding tow bars. One will be<br />
placed between the third and fourth container as previously<br />
mentioned and the other will be between the fifth and sixth<br />
container (i.e., in a 3-2-2 pattern).
