The document outlines a training and certification program for certified ESD (Electrostatic Discharge) operators, detailing the nature of ESD, its potential damage, control measures, and training requirements. It specifies responsibilities for ESD control within the organization, outlines employee responsibilities, and safety protocols for handling ESD-sensitive devices. Additionally, it covers proper packaging, marking of ESD-sensitive items, and the importance of using appropriate ESD protective equipment.

Controlling ESD

9. ESD CONTROL
PROGRAM
Who is responsible for ESD control?
• Overall it’s the Production Manager, Richard Millam,
with support from ESD coordinator, Rachael
Wiltshire.
• Stores are responsible for ensuring correct packaging
is used.
• All have a responsible for the area you work in.
What is your Site ESD Control Policy?
• ESD control plan PV309, in line with BS EN 61340‐5‐1.
• Located: Y:QUALITYQuality ManualPV Level
3PV309_10
What processes or locations are ESD sensitive?
• Handling and fitment of any ESD items.
• Stores, shop floor, any area with a set boundary.
Are any processes exempt from ESD controls?
• High voltage testing (Safety Related).

10. TRAINING
When do your operators need to complete initial training?
• Ideally, training should be before they handle sensitive devices.
How often do your students need to complete refresher training?
• Training to be recertified in 2 years.
What does your site require for visitors or untrained personnel?
• Visitors are to only enter an ESD area with trained personnel. It is the trained
persons responsibility to ensure they follow precautions.
What is the employee’s responsibility when they see untrained personnel
handling ESD sensitive devices?
• Report all incidents to your manager or ESD Coordinator.

11. EPA REQUIREMENTS
What are the requirements within an EPA?
• Wrist strap to be worn when handling all unpackaged
products.
• Wear closed garment.
• Wear ESD shoes or foot grounders.
• Test wrist strap and foot grounders twice a day
• Only trained or escorted personnel allowed within an EPA.
• ESD signage displayed
• No insulators
• Clear boundary
Does the employee perform a daily surveillance of their EPA before
starting work?
• Check that worksurface grounds are connected.
• Clean worksurface at the start of the shift.
• Remove unnecessary static generating materials from the worksurface before
handling ESD sensitive devices

12. GROUNDED WORKSURFACES
What are the requirements at a workstation?
• Ensureyourworkbenchhasbeentestedandhasanindateindicationlabel.
• Workstationsaretobeclearofanyunnecessaryitems.
• SurfaceiscleanandonlyESDcleanerisused.
• Allpaperworkandotheressentialinsulatorsistobekept30cmawayfromESDSorinstaticdissipativesleeve.
• Ensurewrist strapsystemcanbeconnectedproperlytotheworkstation.
What do I do If I find a loose or broken ground wire?
• Any visible damage is to be reported immediately and work is to be stopped until the ground
wire is reconnected and tested.

13. Personnel grounding

14. WRIST STRAP SYSTEMS
We use a non-monitored Wrist Strap System, how is this system
verified?
• Wearing wrist straps properly, how?
• Various types, such as fabric and metal.
• Wrist strap testers, where are they? How to test?
• Fill in log sheet provided.
• Testers must be calibrated and have a calibration sticker.
What to do if wrists strap fails?
• Try adjusting wrist strap.
• If fails after three attempts contact manager for a new wrist
strap/cord.
Other Wrist strap system?
• Monitored system

15. PERSONNEL
GROUNDING -Garments
What is your company policy on Static Control
garments?
• Garments must be worn at all times in the
EPA, by everyone.
• How are they worn?
• Garments are not to be washed at home as
they can be damaged by certain bleaches,
please use the laundry bins provided.
• Visitors maybe identified in a different
colour garment
What other types of ESD garment are there?
• Groundable Static Control Garment
*Any damaged garments are to be reported to your manager*

16. Equipment grounding

17. FOOTWEAR/FLOORING
Footwear/Flooring Systems
• Phoenix has a ESD floor , this is made up of ESD conductive tiles (unit 48 ONLY).
• Flooring only works with appropriate footwear.
• What are the type(s) of footwear?
• ESD shoes and grounders are made of conductive materials which allow you to be grounded
to the ESD floor.
• Wearing ESD shoes without ESD flooring doesn’t work.
How do you verify that the system is functional?
• Footwear Testers? Where are they?
• Testers must be calibrated and have a calibration sticker.
What to do if foot grounding fails?
• Try adjusting or cleaning the strap.
• If fails after three attempts contact manager for a new strap/heel grounder.
• Shoes could be damaged and need replacing.

18. SEATING and TROLLIES
Why ESD chairs?
• Chairs have conductive gliders/casters which allow s
static electricity to dissipate to earth using the ESD
floor.
• They also have conductive materials which prevent
static build up.
Why ESD trollies?
• ESD trollies have drag chains which allows the static
electricity to dissipate to earth using the ESD floor,
trollies also have conductive casters.
• They also have conductive materials which prevent
static build up

19. SHELVING and IONIZATION
What is your company policy on shelving?
• All shelving within Phoenix Systems is grounded to a common ground using drag chains.
• All items placed on the shelving should still be in a dedicated carrier or ESD shielded bag.
• Avoid placing any insulated items alongside any shelving units.
• ESD shelves can be identified by there chrome structure, ESD symbol or ESD castors.
What is ionization?
• Ionization is the use of ionizers to neutralize static charge by balancing the ions.
• They are used when insulators cannot be removed from the EPA.
• When used they must not be interrupted and appropriate setting used such as, distance,
airflow speed). They must also be pointed in the right direction.

20. Packaging and Marking

21. PACKAGING MATERIALS
How does your company package ESD sensitive devices for:
• Movement within an EPA? (i.e. movement between workstations)
• Dissipative bags (pink), black conductive boxes.
• Movement between EPA’s (leaves a controlled area for a short time and re-enters other EPA)?
• Shielding bag (metallic), external anti static packaging, conductive box with lid.
• Movement outside the EPA (packaging for delivery to a customer)?
• Anti static bag with antistatic packaging, secondary packaging can be used but must bear ESD symbol.
Do you re-use or recycle ESD packaging materials?
• ESD packaging can be reused as long as it isn’t damaged.
* All ESD packaging must be marked with correct symbol*

22. MARKING
ESD Susceptible symbol
• This symbol is used to indicate that a item is susceptible to
damage from an ESD event.
• Sometimes found on PCB or on there outer packaging as a
warning.
• This symbol should be used on customer packaging to
indicate sensitive device.
ESD protective symbol
• This symbol is used to indicate items that are specifically
designed to provide ESD protection.
• They are found on ESD packaging, garments and personnel
grounding equipment.
• If this symbol is not present on any packaging the
packaging isn’t approved.
• S underneath symbol indicates shielding.
• D underneath symbol indicates dissipative.
