Cleanroom TN2000 Series 12 Nitrile Gloves (ESD-Safe) — what this glove is designed to control
Cleanroom TN2000 Series 12 nitrile gloves are designed for cleanroom workflows where electrostatic discharge (ESD) is a process risk and where
glove selection must support static control at the point-of-use without compromising contamination control. In electronics, optics, and sensitive
assembly environments, ESD risk and contamination risk are often linked: the same uncontrolled handling behaviors that create particles and residues can also cause
charge generation and discharge events.
ESD-safe gloves are typically selected when operators must touch components, tooling, or packaging that can be damaged by static. However, the glove alone does not
“solve ESD.” It must be deployed inside a complete ESD control system: grounding, surfaces, garments, humidity controls (where allowed), and verification. The glove
is a critical link in that chain—especially where product-contact handling and contamination controls must remain disciplined.
Operations takeaway: ESD-safe gloves work when they are treated as part of an ESD system and a cleanroom system—managed by SOP, not by habit.
ISO-first context: personnel are the dominant contamination source—ESD adds another failure mode
ISO 14644 operations guidance identifies personnel as a primary contamination source in cleanrooms. Gloves are the boundary layer between operators and controlled
surfaces. In ESD-sensitive operations, the glove boundary layer also becomes a key interface for charge generation and discharge control. This is why ESD glove
programs should define: what gloves may touch, how operators move through zones, and how gloves are changed or replaced when contaminated or damaged.
USP-style operational thinking is useful here even outside of pharmacy: define a method, train it, and audit it so outcomes are repeatable. ESD and contamination issues
often show up as “intermittent” events—meaning the method is drifting, not that the parts are random.

Verification note: If ESD is critical, define how the glove is verified (e.g., work practice checks, system testing) within your ESD program.
Best-practice use (ESD-safe handling that also respects cleanroom discipline)
Best practice begins with correct donning and fit. Gloves should be donned per gowning SOP without snapping or aggressive stretching that can generate particles and charge.
Correct sizing matters: loose gloves increase friction, slippage, and re-handling; overly tight gloves increase fatigue and promote risky touch behavior. Once donned, keep hands
within the defined controlled work zone and avoid touching non-controlled surfaces (carts, phones, keyboards, door handles). This reduces both contamination transfer and ESD risk.
Integrate glove use into the ESD system. Gloves should be used alongside proper grounding, ESD work surfaces, approved garments, and handling tools. If operators are grounded but gloves
are not appropriate for the ESD program, static events can still occur at the point-of-touch. Conversely, if gloves are ESD-safe but operators touch non-controlled surfaces and return
to product work, you have solved one risk while creating another.
Define glove change triggers with ESD work in mind. Replace gloves after contact with non-controlled surfaces, after leaving the controlled area, after solvent-heavy work, after defined
time intervals, and immediately after any integrity compromise. Progressive glove loading (residue and particulate) can change surface behavior and increase both contamination transfer and
handling variability.
Typical cleanroom + ESD failures and how to avoid them (ISO-minded)
- “ESD glove, non-ESD behavior”: Gloves are ESD-safe but operators are not grounded or the workstation is not controlled. Prevention: integrate gloves into the complete ESD program.
- Touch drift: Gloves touch non-controlled surfaces (carts, boxes) then return to components. Prevention: work zone rules and immediate glove change triggers.
- Intermittent ESD events: Often method drift (movement, handling, humidity variability). Prevention: training + verification checks and documented work practices.
- Residue transfer after solvent work: Gloves become loaded and change surface behavior. Prevention: task-based glove changes and controlled wetness.
- Unapproved substitutions: A non-ESD glove replaces an ESD glove (or vice versa). Prevention: lock the approved glove SKU(s) in SOP and procurement; require written approval to substitute.
Suggested companion products and technical rationale
SOSCleanroom commonly pairs glove programs with controlled cleaning tools and solvents so the method remains repeatable. In ESD-sensitive environments, consider adding ESD-safe
cleaning tools when static is a risk at point-of-use.
Defensible pairing principle: Gloves control personnel contamination; ESD-safe programs control static; swabs/wipers control contact geometry and pickup; solutions control solvency and drying behavior.
Standardizing these elements reduces intermittent defects and supports a more auditable method.
