Safety—Rigid Washer Extractors

1. General Safety Requirements—Vital Information for

Management Personnel

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.

[Document BIUUUS04]

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.

About the Forces Transmitted by Milnor® Washer-extractors

About the Forces Transmitted by Milnor Washer-extractors

During washing and extracting, all washer-extractors transmit both static and dynamic (cyclic) forces to the floor, foundation, or any other supporting structure. During washing, the impact of the goods as they drop imparts forces which are quite difficult to quantify. Size for size, both rigid and flexibly-mounted machines transmit approximately the same forces during washing. During extracting, rigid machines transmit forces up to 30 times greater than equivalent flexibly-mounted models. The actual magnitude of these forces vary according to several factors:

• machine size,

• final extraction speed,

• amount, condition, and type of goods being processed,

• the liquor level and chemical conditions in the bath preceding extraction, and

• other miscellaneous factors. Estimates of the maximum force normally encountered are available for each Milnor

and size upon request. Floor or foundation sizes shown on any Milnor on-grade situations based only on previous experience without implying any warranty, obligation, or responsibility on our part.

Rigid Machines

Size for size, rigid washer-extractors naturally require a stronger, more rigid floor,

foundation, or other supporting structure than flexibly-mounted models. If the supporting soil under the slab is itself strong and rigid enough and has not subsided to leave the floor slab suspended without support, on grade installations can often be made directly to an existing floor slab if it has enough strength and rigidity to safely withstand our published forces without transmitting undue vibration. If the subsoil has subsided, or if the floor slab itself has insufficient strength and rigidity, a deeper foundation, poured as to become monolithic with the floor slab, may be required. Support pilings may even be required if the subsoil itself is “springy” (i.e., if its resonant frequency is near the operating speed of the machine). Above-grade installations of rigid machines also require a sufficiently strong and rigid floor or other supporting structure as described below.

Flexibly-mounted Machines

Size for size, flexibly-mounted machines generally do not require as strong a floor,

foundation, or other supporting structure as do rigid machines. However, a floor or other supporting structure having sufficient strength and rigidity, as described in section 3, is nonetheless vitally important for these models as well.

How Strong and Rigid?

Many building codes in the U.S.A. specify that laundry floors must have a minimum live

load capacity of 150 pounds per square foot (732 kilograms per square meter). However, even compliance with this or any other standard does not necessarily guarantee sufficient rigidity. In any event, it is the sole responsibility of the owner/user to assure that the floor and/or any other supporting structure exceeds not only all applicable building codes, but also that the floor and/or any other supporting structure for each washer-extractor or group of washer-extractors actually

has sufficient strength and rigidity, plus a reasonable factor of safety for both, to support the weight of all the fully loaded machine(s) including the weight of the water and goods, and including the published 360º rotating sinusoidal RMS forces that are transmitted by the machine(s). Moreover, the floor, foundation, or other supporting structure must have sufficient rigidity (i.e., a natural or resonant frequency many times greater than the machine speed with a reasonable factor of safety); oth erwise, the m enti oned 360º ro ta ting sinuso ida l RMS forces can be multiplied and magnified many times. It is especially important to consider all potential vibration problems that might occur due to all possible combinations of forcing frequencies (rotating speeds) of the machine(s) compared to the natural frequencies of the floor and/or any other supporting structure(s). A qualified soil and/or structural engineer must be engaged for this purpose.

Avoiding Damage From Allied Remote Chemical Delivery Systems

Milnor® does not manufacture or supply remote chemical delivery systems and this document is meant only to illustrate some of the possible problems that can be minimized during installation of such systems by the chemical supply company. Milnor washer-extractors and CBW washers (tunnels) are available with convenient inlets for such systems (see Figure 1). Most common of the types of systems currently used in commercial laundering operations are pumped chemical systems. Other types, such as constant pressure, re-circulating ring main systems have also been, and may continue to be used with Milnor equipment.

This document warns about some of the possible hazards posed by chemical systems and lists certain requirements needed to minimize those hazards. The procedures for interfacing with allied chemical systems and information pertinent to chemical use in general are provided elsewhere in the product manuals (see Note 1).

Milnor has manufactured washer-extractors and tunnel washers with the same stainless steel specification since its founding. Every batch of steel used is certified and documented by the steel mill. Testing of samples damaged by corrosion have, in every case, proven the steel to be well within the AISI 304 specification.

Avoiding Damage From Allied Remote Chemical Delivery Systems

Chemical products commonly found in the laundry industry, when used in established dosages and proper operating parameters, under the auspices of an experienced chemical specialist, should produce satisfactory results, with no consequential detrimental effects. The industry has published standards in Riggs and Sherrill, “Textile Laundering Technology”. However, the stainless steel can be damaged and even destroyed by abnormal contact with chlorine bleach, hydrofluosilicic acid and other commonly used chemicals, as will occur if chemicals are unintentionally leaked into the machine, particularly when it is no longer in use and especially when machine surfaces are dry.

Some chemical systems have been found to permit chemicals to dribble from the supply lines, or worse, to siphon from the supply tank into the machine, during operation and long after the system is shut down—as after working hours and during weekends. If this occurs, deterioration

(rusting) of the stainless steel and damage to any textiles therein will inevitably result. If this condition goes undetected, machine damage is likely to be catastrophic. No machine is

immune to such damage.

CAUTION 1 : Equipment and Textile Damage Hazards

—Chemicals leaked into the

machine, particularly when it is idle can destroy machine components and textiles left in the machine. Pellerin Milnor Corporation accepts absolutely no responsibility for damage to its

equipment or to textiles therein from abnormal contact with chemicals.

• Ensure that the chemical system prevents uninten ti ona l rele ase of chemicals.

• Inspect regularly for proper operation and evidence of damage.

Requirements for Chemical Systems Used With Milnor Machines

It is the responsibility of the chemical system manufacturer and supplier to ensure that their system is safe for personnel and equipment. Some important points are described below.

2.1.

Ensure the System Cannot Siphon.

—The supply system must be designed to counteract any siphoning that could occur as a result of having a sealed supply line between the bottom of the chemical tank and the internal machine connection at the drain trough. As shown in the Figure 2 examples, if the pump (P) and/or the valving does not provide positive closure and there is no vacuum breaker protection, siphoning is likely to occur. In each of the Figure 2 illustrations, the volume of chem ical in the tank above th e siphon level (S), and indi ca ted by shading, will flow into the machine.

2.2.

Ensure the Chemical Lines Cannot Dribble

provide a means of positively closing the chemical line at the pump location, but not at the injection site. Hence, any concentrated chemical that remains in the injection line between the pump and the machine is free to flow into the machine. Some examples of this are shown in Figure 3.

Design and Installation Recommendations

It is the responsibility of the chemical system manufacturer and supplier to use whatever measures are necessary to ensure that their system is safe for personnel and equipment. The

following are some of the possible methods the manufacturer or supplier may wish to use, as appropriate.

3.1.

Siphoning: Positively close the line.

—If the pump does not provide positive closure

when the system is off, employ a shutoff valve in the line to serve this purpose.

3.2.

Siphoning: Break the siphon.

—Provide an air gap or vacuum breaker in the chemical

delivery line. This must be located above the “full” line of the tank.

3.3.

Dribbling: Flush the entire chemical delivery line.

—If any concentrated chemical that remains in the injection line between the pump and the machine is free to flow into the machine, employ a system that flushes the entire line between the pump and the injection point with fresh water after each injection.

PELLERIN MILNOR CORPORATION

3.4.

Dribbling: Locate the entire chemical line below the machine inlet.

— Assuming the chemical system does not retain any line pressure and that the pump provides positive closure when the system is off, locate the entire chemical delivery line below the level of the chemical inlet. An example of this is shown in Figure 4.

Guarding Against Leaks

All personnel who may work with the chemical system (e.g., chemical system manufacturer, chemical system supplier, chemical supplier, operator, maintenance personnel) should be vigilant in observing for leaks in the system. When connecting, or reconnecting chemical lines, whether at installation, after taking samples, or when replacing components, at a minimum ensure that:

1. the proper components are used,

2. all connections are the proper fit, and

3. all components are securely connected.

CAUTION 2 : Injury and Damage Hazards

may be corrosive or toxic. Such chemicals can injure personnel and damage equipment.

• Use care when connecting chemical lines.

• Inspect regularly for leaks.
