1. General Safety Requirements—Vital Information for
Management Personnel[Document BIUUUS04]
Incorrect installation, neglected preventive maintenance, abuse, and/or improper repairs, or
changes to the machine can cause unsafe operation and personal injuries, such as multiple
fractures, amputations, or death. The owner or his selected representative (owner/user) is
responsible for understanding and ensuring the proper operation and maintenance of the machine.
The owner/user must familiarize himself with the contents of all machine instruction manuals.
The owner/user should direct any questions about these instructions to a Milnor® dealer or the
Milnor® Service department.
Most regulatory authorities (including OSHA in the USA and CE in Europe) hold the owner/user
ultimately responsible for maintaining a safe working environment. Therefore, the owner/user
must do or ensure the following:
• recognize all foreseeable safety hazards within his facility and take actions to protect his
personnel, equipment, and facility;
• work equipment is suitable, properly adapted, can be used without risks to health or safety,
and is adequately maintained;
• where specific hazards are likely to be involved, access to the equipment is restricted to those
employees given the task of using it;
• only specifically designated workers carry out repairs, modifications, maintenance, or
servicing;
• information, instruction, and training is provided;
• workers and/or their representatives are consulted.
Work equipment must comply with the requirements listed below. The owner/user must verify
that installation and maintenance of equipment is performed in such a way as to support these
requirements:
• control devices must be visible, identifiable, and marked; be located outside dangerous zones;
and not give rise to a hazard due to unintentional operation;
• control systems must be safe and breakdown/damage must not result in danger;
• work equipment is to be stabilized;
• protection against rupture or disintegration of work equipment;
• guarding, to prevent access to danger zones or to stop movements of dangerous parts before
the danger zones are reached. Guards to be robust; not give rise to any additional hazards; not
be easily removed or rendered inoperative; situated at a sufficient distance from the danger
zone; not restrict view of operating cycle; allow fitting, replacing, or maintenance by
restricting access to relevant area and without removal of guard/protection device;
• suitable lighting for working and maintenance areas;
• maintenance to be possible when work equipment is shut down. If not possible, then
protection measures to be carried out outside danger zones;
• work equipment must be appropriate for preventing the risk of fire or overheating; discharges
of gas, dust, liquid, vapor, other substances; explosion of the equipment or substances in it.

Proximity Safeguarding for Automatic Shuttle Conveyors
Proximity safeguarding—a means of preventing personnel from entering the path of a machine,
such as an industrial robot, that moves within a large area.
1.
Applicability
This document—
applies to Milnor®automated laundering systems with shuttle conveyors that move without
operator intervention (automatic operation),
does not apply to shuttles that require operator input continually, such as directing all shuttle
movements (manual operation).

3.
Hazards To Personnel in Proximity to Shuttle Conveyors
Milnor automated laundering systems use automatic shuttle conveyors to transport goods among
the processing machines in the system. Depending on model, an automatic shuttle conveyor may
move in any of the following ways, in addition to running its conveyor belt(s):
• It may travel along (traverse) a line of machines (typically dryers).
• Its conveyor bed(s) may ascend and descend (elevate) within the machine frame.
• Its conveyor bed(s) may extend and retract within the machine frame.
• The conveyor bed and frame may pivot.
• Wet goods shuttles have a bucket that elevates and tilts.
These motions pose strike, crush, sever, and entrapment hazards to personnel in proximity to the
shuttle. For the safety of personnel, owner/users must provide proximity safeguarding that
protects personnel from the moving shuttle.
A common method of proximity safeguarding is safety fencing with interlocked gates that disable
the shuttle when a gate is opened. When a shuttle is disabled, this will eventually cause other
machines in the system to hold (wait for action from another machine), but it will not necessarily
cause them to immediately stop moving. In the case of a tunnel system, the press or centrifugal
extractor can pose additional hazards to personnel in proximity to the equipment. Hence, the
safeguards must also disable any presses or extractors. Tunnels and dryers do not pose a
significant hazard to personnel merely because they are in proximity to the equipment, and need
not be automatically disabled.
WARNING
1 : Multiple Hazards—Proximity safeguarding provides only partial protection
and only against injury resulting from entering the shuttle path. It is not a substitute for proper
11

Proximity Safeguarding for Automatic Shuttle Conveyors
PELLERIN MILNOR CORPORATION
lockout/tagout procedures and good safety practices.
•
Always lockout/tagout any individual machine (or follow the published maintenance
procedures) when performing maintenance or clearing a fault on that machine.
•
Ensure that all personnel understand the safeguards and do not attempt to defeat them.
•
Inspect safeguards weekly to ensure that they are not mechanically or electrically
circumvented.
4.
How Milnor Accommodates Proximity Safeguarding
Milnor provides connection points on shuttles, presses and centrifugal extractors for interfacing
with devices such as gate interlock switches. These connection points are tagged for easy
identification. When Milnor provides equipment layout drawings for an automated laundering
system, it indicates on the drawing, the perimeter of the shuttle movement area that must be
guarded. The following hazard statement is displayed on connection point tags as well as
equipment layout drawings prepared by Milnor:
WARNING
2 : Strike, Crush, Sever, and Entrapment Hazards—Serious bodily injury
or death can result to personnel in proximity to machinery/systems that traverse, elevate, extend,
pivot, an
d/or tilt. The following mandatory minimum safety requirements must be installed with
the machinery system (local codes may require additional precautions):
•
Safety fence enclosing machine movement areas,
•
Lockable electrical interlocks on all gates, properly interfaced as shown on machine
schematics, to disable machine movement when any gate is opened,
•
Signs to alert personnel to these hazards, placed prominently around the fenced area.
Although the objectives of proximity safeguarding are the same anywhere, design requirements
vary with local codes (which occasionally change) and with the plant layout. For this reason,
Milnor does not provide detailed designs or materials for proximity safeguarding. If the necessary
expertise does not exist within the owner/user's organization, consult appropriate sources such as
local engineers or architects specializing in industrial facility design.
5.
Examples of Safety Fencing With Interlocked Gates
Fencing with interlocked gates like that depicted in Figure 1 and Figure 2, may be used to meet
the proximity safeguarding requirement. Should the owner/user choose this method, the following
information may be useful. However, this information may not satisfy current or local code
requirements. The owner/user must determine its suitability for his particular facility.

Proximity Safeguarding for Automatic Shuttle Conveyors
PELLERIN MILNOR CORPORATION
5.1.
Fence Dimensions—The fence must discourage climbing over and prevent crawling under.
5.2.
Fence Materials and Setback—The fence must be constructed of materials and located so
as to prevent personnel from reaching through gaps in the fence and contacting the enclosed
machinery.
5.3.
Gates—Personnel gates must be held firmly closed but permit personnel to easily pass through
when necessary. Gates must be equipped with a positive latching arrangement to prevent
accidental opening. Adequate floor space must be prov
ided to allow the gate to swing at least 90
degrees when fully open. Gates must open outward; that is, away from the fenced perimeter. The
floor must be permanently marked to show the gate’s swing area, to discourage obstructing its
movement.
5.4.
Control Circuitry—All gates must be electrically interlocked with any shuttle conveyors
within the fenced area and with any presses or centrifugal extractors that the fence either encloses
or intersects. Opening any gate must have the following effects:
1. Shuttle(s), press(es), and/or centrifugal extractor(s) stop moving immediately.
2. An audible alarm sounds.
3. Shuttle(s), press(es), and/or centrifugal extractor(s) cannot be restarted merely by closing the
gate(s), but must be restarted at the machine control panel once the gate(s) are closed.
Milnor shuttles, presses and centrifugal extractors provide such functionality when properly
interfaced with gate interlock switches.
5.5.
System Emergency Stop Switches—The laundry must establish rules and procedures
that prohibit personnel from remaining within the fenced area with machine(s) enabled, except in
accordance with published maintenance procedures. System emergency stop switches (panic
buttons) should be prov
ided inside and outside the fenced perimeter. Emergency stop switches
should be located so that personnel anywhere inside the fenced perimeter are only a short
distance from a switch, and they should be clearly marked as to their locations and function.
Co
nnect switches in series with the gate interlocks so that pressing an emergency stop switch
performs the same control function as opening a gate.
5.6.
Isolating Individual Machine Controls—The interlock circuitry for each machine must
be electrically isolated from that of the other machines. Hence, each gate interlock switch must
provide as many pairs of dry contacts as there are machines to interface to. A pair of switch
contacts must never be shared by two or more machines.
5.7.
Recommended Signage—Safety placards should be posted along the fence and at each
gate, alerting personnel to the hazards within. At minimum, the
size of lettering and distance
between placards should be such that anyone contemplating entering the fenced area will likely
see and read the placard first. Wording should be provided in each native language spoken by
laundry personnel.

1. What Safety Supports are Provided and Why
BNSUUH01.C02 0000374278 A.7 8/19/21 9:52 AM Released
These machines are provided with two safety pins. After the bed is raised, the pins are inserted in
holes in both sides of the frame. The safety pins provide protection against the unpowered descent
of the bed during maintenance. A mechanical problem such as a broken chain can cause the bed
to fall. Use the safety support(s) whenever the maintenance to be performed requires you to place
any part of your body in or near the path of the vertically moving portion of the machine.
WARNING: Incorrect use of the safety supports — can cause the machine to descend
and crush you.
�Never work near the path of the vertically moving portion of the ma-
chine unless the safety supports are deployed and power is removed from
the machine.
�Do not use power to close a small gap between the machine and the
safety supports. Use care not to lower the machine with the safety supports
deployed.
�Where a pair of safety supports is provided, always use both supports.
�Maintain the safety support(s) in good condition.
�When not in use, stow the safety support(s) in the location(s) provided on the machine
or in a convenient, designated location.
