Additive Feeders Chapter 1: Safety vi

1-3 Responsibility

These machines are constructed for maximum operator safety when used under standard
operating conditions and when recommended instructions are followed in the maintenance
and operation of the machine.

All personnel engaged in the use of the machine should become familiar with its operation as
described in this manual.

Proper operation of the machine promotes safety for the operator and all workers in its
vicinity.

Each individual must take responsibility for observing the prescribed safety rules as outlined.
All warning and danger signs must be observed and obeyed. All actual or potential danger
areas must be reported to your immediate supervisor.

General Responsibility

No mater who you are, safety is important. Owners, operators and maintenance personnel
must realize that every day, safety is a vital part of their jobs.

If your main concern is loss of productivity, remember that production is always affected in a
negative way following an accident. The following are some of the ways that accidents can
affect your production:

• Loss of a skilled operator (temporarily or permanently)

• Breakdown of shop morale

• Costly damage to equipment

• Downtime

An effective safety program is responsible and economically sound.

Organize a safety committee or group, and hold regular meetings. Promote this group from
the management level. Through this group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the meetings.

Hold daily equipment inspections in addition to regular maintenance checks. You will keep
your equipment safe for production and exhibit your commitment to safety.

Please read and use this manual as a guide to equipment safety. This manual contains safety
warnings throughout, specific to each function and point of operation.

Additive Feeders Chapter 1: Safety vii

Operator Responsibility

The operator’s responsibility does not end with efficient production. The operator usually has
the most daily contact with the equipment and intimately knows its capabilities and
limitations.

Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or
through a casual attitude toward machinery formed over a period of months or years. Your
employer probably has established a set of safety rules in your workplace. Those rules, this
manual, or any other safety information will not keep you from being injured while operating
your equipment.

Learn and always use safe operation procedures. Cooperate with co-workers to promote safe
practices. Immediately report any potentially dangerous situation to your supervisor or
appropriate person.

REMEMBER:

• NEVER place your hands or any part of your body in any dangerous location.

• NEVER operate, service, or adjust the feeder without appropriate training and first

reading and understanding this manual.

• NEVER try to pull material out of the feeder with your hands while it is running!

• Before you start the feeder check the following:

• Remove all tools from the feeder;

• Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the

hopper area;

• If your feeder has been inoperative or unattended, check all settings before starting the

unit.

• At the beginning of your shift and after breaks, verify that the controls and other

auxiliary equipment are functioning properly.

• Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify,

or remove safety guards. Such alteration is not only unsafe, but will void the warranty
on your equipment.

• When changing control settings to perform a different mode of operation, be sure

selector switches are correctly positioned. Locking selector switches should only be
adjusted by authorized personnel and the keys removed after setting.

• Report the following occurrences IMMEDIATELY:

• unsafe operation or condition

• unusual feeder action

• leakage

• improper maintenance

• NEVER stand or sit where you could slip or stumble into the feeder

while working on it.

• DO NOT wear loose clothing or jewelry, which can be caught while working on a

feeder. In addition, cover or tie back long hair.

Additive Feeders Chapter 1: Safety viii

• Clean the feeder and surrounding area DAILY, and inspect the machine for loose,

missing or broken parts.

• Shut off power to the feeder when it is not in use. Turn the switch to the OFF

position, or unplug it from the power source.

Maintenance Responsibility

Proper maintenance is essential to safety. If you are a maintenance worker, you must make
safety a priority to effectively repair and maintain equipment.

Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric
supplies and all accessory equipment at the machine, and disconnect and lockout electrical
power. Attach warning tags to the disconnect switch.

When you need to perform maintenance or repair work on equipment above floor level, use a
solid platform or a hydraulic elevator. If there is a permanently installed catwalk on your
equipment, use it. The work platform should have secure footing and a place for tools and
parts. DO NOT climb on equipment, machines, or work from ladders.

If you need to repair a large component, use appropriate handling equipment. Before you use
handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes)
be sure the load does not exceed the capacity of the handling equipment or cause it to become
unstable.

Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using
them to lift a load.

Be sure that all non-current carrying parts are correctly connected to earth ground with an
electrical conductor that complies with current codes. Install in accordance with national and
local codes.

When you have completed the repair or maintenance procedure, check your work and remove
your tools, rigging, and handling equipment.

Do not restore power to the equipment until all persons are clear of the area. DO NOT start
and run the machine until you are sure all parts are functioning correctly.

BEFORE you turn the machine over to the operator for production, verify all equipment
enclosure panels, guards and safety devices are in place and functioning properly.

Reporting a Safety Defect

If you believe that your equipment has a defect that could cause injury, you should
immediately discontinue its use and inform the manufacturer.

The principle factors that can result in injury are failure to follow proper operating procedures
(i.e. lockout/tagout), or failure to maintain a clean and safe working environment.

2-6 Safety Devices and Interlocks

This section includes information on safety devices and procedures that are inherent to the
additive feeder. This manual is not intended to supersede or alter safety standards established
by the user of this equipment. Instead, the material contained in this section is recommended
to supplement these procedures in order to provide a safer working environment.

At the completion of this section, the operator and maintenance personnel will be able to do
the following:

• Identify and locate specific safety devices.

• Understand the proper use of the safety devices provided.

• Describe the function of the safety device.

Safety Circuit Standards

Safety circuits used in industrial systems protect the operator and maintenance personnel
from dangerous energy. They also provide a means of locking out or isolating the energy for
servicing equipment.

Various agencies have contributed to the establishment of safety standards that apply to the
design and manufacture of automated equipment. The Occupational Safety and Health
Administration (OSHA) and the Joint Industrial council (JIC) are just a few of the
organizations that have joined with the plastics industry to develop safety standards.

Every effort has been made to incorporate these standards into the design of the additive
feeder; however, it is the responsibility of the personnel operating and maintaining the
equipment to familiarize themselves with the safety procedures and the proper use of any
safety devices.

Fail Safe Operation

If a safety device or circuit should fail, the design must be such that the failure causes a
“Safe” condition. As an example, a safety switch must be a normally open switch. The switch
must be held closed with the device it is to protect. If the switch fails, it will go to the open
condition, tripping out the safety circuit.

At no time should the safety device fail and allow the operation to continue. For
example, if a safety switch is guarding a motor, and the safety switch fails, the motor should
not be able to run.

Additive Feeders Chapter 2: Functional Description 13 of 50

Safety Device Lock-Outs

Some safety devices disconnect electrical energy from a circuit. The safety devices that are
used on these additive feeders are primarily concerned with electrical power disconnection
and the disabling of moving parts that may need to be accessed during the normal operation
of the machine.

Some of the safety devices utilize a manual activator. This is the method of initiating the
safety lock out. This may be in the form of a plug, lever or a handle. Within this lockable
handle, there may be a location for a padlock. Personnel servicing the equipment should
place a padlock in the lockout handle.

In addition to the safety devices listed above, these additive feeders are equipped with a line
cord plug. This allows the operator or maintenance personnel to unplug the additive feeder
from its power source and tag it out. The plug can then be tagged with any number of
approved electrical lockout tags available at most electrical supply stores.

WARNING! Always disconnect and lockout all electrical power and pneumatic (i.e. compressed air)

sources prior to servicing or cleaning the additive feeder. Failure to do so may result in
serious injury. No one but the person who installed the lockout may remove it.
