Extrusion Control & Extruder Monitor Units Chapter 1: Safety 11
• DO NOT wear loose clothing or jewelry, which can be caught while working on an
extrusion control or extruder monitor unit. In addition, cover or tie back long hair.
• Clean the extrusion control or extruder monitor unit and surrounding area DAILY, and
inspect the machine for loose, missing or broken parts.
• Shut off power to the extrusion control or extruder monitor unit 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 an extrusion control or extruder
monitor unit above floor level, use a solid platform or a hydraulic elevator. If there is a
permanently installed catwalk around your extrusion control or extruder monitor unit, use it.
The work platform should have secure footing and a place for tools and parts. DO NOT
climb on unit, 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 extrusion control or extruder monitor unit until all persons are
clear of the area. DO NOT start and run the unit until you are sure all parts are functioning
correctly.
BEFORE you turn the extrusion control or extruder monitor unit over to the operator for
production, verify all 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.
