Engineering Protection
for the Exposed Hand

Section 01 — Framing the Problem

Hand exposure is broader than the cut hazard most programmes are built around

Industrial hands are injured by far more than sharp edges. Impact, crushing, pinching, struck-by and caught-between events account for a substantial share of hand trauma across oil and gas, mining, ports, steel, and heavy engineering — yet most glove-selection programmes are still built around a single variable: palm cut resistance.

A worker's hand enters hazard zones through specific, identifiable pathways: contact with moving equipment, tool use, manual handling of tubulars and rigging hardware, and maintenance activity carried out close to steel components. Each of these pathways exposes a different part of the hand to a different injury mechanism. A glove chosen for palm cut resistance alone may leave the knuckles, fingers and metacarpals — the parts of the hand most exposed during impact and struck-by events — without meaningful protection.

Traditional glove-selection systems have tended to focus on three variables: palm material, cut-resistance rating, and price per pair. This is necessary but incomplete. It has historically under-weighted back-of-hand exposure, impact-zone coverage, task geometry, hand position during the task, finger articulation requirements, and the residual risk that remains after engineering controls have already been applied.

The framework this whitepaper proposes

This document sets out a structured, seven-step approach to hand protection that places task analysis before product selection:

1. Understand the task. What is being handled, what forces are involved, what is the hand expected to do.
2. Identify where the hand enters. The specific point and part of the hand exposed to the hazard.
3. Determine what can contact the hand. The object, surface, or moving element responsible for potential injury.
4. Remove avoidable exposure. Apply distance, tools, guarding, or task redesign before considering PPE.
5. Map residual exposure. Document what risk remains once engineering controls are in place.
6. Select appropriate glove protection. Match glove specification to the residual exposure, not to habit or catalogue position.
7. Validate the choice in the field. Confirm performance under real task conditions before standardising.

Within this framework, task-specific impact gloves — including the KONG® platform discussed in Section 9 — occupy a defined role: protecting the residual interaction that remains once avoidable exposure has been engineered out. They are presented here as one component of a control system, not as a substitute for it.

Section 02 — Historical Context

The hand is not one impact zone

For most of industrial history, hand protection meant palm protection. Cotton gloves, PVC-dotted gloves, leather gloves and basic coated general-purpose gloves were designed primarily to manage grip, abrasion and minor cut exposure on the palm and fingers. They served these purposes adequately. They were not designed to manage heavy dorsal — back-of-hand — impact exposure, because for much of that history, that exposure was not yet recognised as a distinct category requiring its own engineering response.

The hand is not a single uniform surface. It is a set of structurally distinct regions, each with different injury mechanisms when struck, crushed, or caught:

• Knuckles — bony prominences with minimal soft-tissue cushioning; highly vulnerable to fracture under direct impact.
• Metacarpals — the long bones of the back of the hand; susceptible to fracture under crushing or heavy blunt force.
• Fingers — narrow, articulated, and frequently positioned closest to the hazard during manual tasks.
• Fingertips — dense in nerve endings; vulnerable to crush and laceration, and critical to dexterity and sensation.
• Thumb — structurally distinct from the fingers, essential to grip function, and frequently exposed during tool use.
• Thumb saddle — the web and base structure connecting the thumb to the palm; a common wear and injury point under repeated tool contact.
• Finger sidewalls — exposed during lateral pinch events, often outside the coverage area of basic gloves.

Because these regions differ in bone structure, soft-tissue depth, mobility requirement and typical hazard exposure, a single glove specification cannot protect all of them equally well. A glove engineered for palm grip and abrasion resistance may offer negligible protection to the knuckles and metacarpals. Recognising this distinction — that the back of the hand is its own hazard zone, with its own injury mechanisms — was the starting point for the development of dedicated impact protection as a category, discussed further in Section 6.

Section 03 — Exposure Mechanisms

Impact is not one event — it is a family of distinct mechanisms

"Impact protection" is often treated as a single category, but the exposures it is meant to address are mechanically distinct from one another. Distinguishing between them matters, because no single glove property addresses all of them equally.

Mechanism	Description
Blunt impact	A single direct strike from a tool, component, or surface against the hand.
Localised impact	Force concentrated on a small contact area — typically knuckles or fingertips.
Repetitive low-energy impact	Frequent minor strikes over a shift, common in striking or hammering tasks.
High-energy impact	A single severe strike, often from a falling or swinging object.
Pinch	The hand caught between two converging surfaces, neither of which is moving with high force.
Crush	Sustained or high-force compression of the hand between two surfaces.
Caught-between	The hand trapped within a closing gap during equipment or load movement.
Struck-by	An object in motion strikes the hand; the hand is not the moving element.
Secondary impact	Impact resulting indirectly from an initial event — e.g. a dropped tool deflecting onto the hand.
Glancing contact	An oblique strike that transmits partial force and may combine impact with abrasion.

A properly engineered impact glove can meaningfully reduce the force transmitted to the hand during blunt, localised, repetitive and certain high-energy impact events. It is not designed to, and cannot reliably be expected to, protect against severe crushing or prolonged entrapment — these mechanisms require engineering controls, not PPE, and are addressed directly in Section 11.

Variables that determine injury outcome

Whether a given impact results in a minor bruise or a fracture depends on more than the glove worn. The relevant variables include:

• Impact energy and the speed of the contacting object
• Contact area — concentrated force on a small area is more damaging than the same energy spread across a larger surface
• Object geometry — sharp edges, corners and points concentrate force differently than flat or rounded surfaces
• Mass of the moving object or component
• Hand position at the moment of contact
• What is directly behind the hand — a hard, unyielding surface increases injury severity compared with a surface that allows some give
• Duration of contact, particularly relevant to crush and caught-between events
• Repeated exposure over a shift, which can produce cumulative soft-tissue trauma even where no single event causes acute injury

Understanding these variables at the task level — rather than assuming "impact-rated" gloves are interchangeable — is the basis for the exposure-mapping approach set out in Section 5.

Section 05 — Methodology

A five-stage method for moving from task to glove specification

The HSF Residual Hand Protection Framework™ structures the decision process described in Section 1 into five stages. Each stage must be completed in sequence — skipping directly to Stage 5 is the most common cause of glove-selection programmes that protect the wrong part of the hand, or protect it against the wrong mechanism.

Stage 1 — Define the Task

Before any glove is considered, the task itself must be understood in mechanical terms:

• What is being handled?
• What is moving — the worker's hand, the component, or both?
• What forces are involved, and at what approximate magnitude?
• What is the hand expected to do — grip, guide, steady, strike, or release?
• What is the duration and frequency of the exposure across a shift?

Stage 2 — Map the Hand Entry Point

Every hand injury has a specific entry point — the moment and location where the hand crossed into the hazard zone. This stage asks:

• Where does the hand enter the hazard?
• Which part of the hand is exposed — palm, knuckle, fingertip, sidewall?
• Is the exposure intentional and necessary to the task, or incidental to how the task happens to be performed?
• Can the hand be replaced at this point by a tool, fixture, or device?

Stage 3 — Identify Exposure Mechanisms

With the entry point defined, the specific mechanisms present at that point must be assessed individually:

• Impact, cut, abrasion, puncture
• Pinch, crush, grip loss
• Heat, cold, chemical contamination
• Wet or oily surface conditions affecting grip

Stage 4 — Remove Avoidable Exposure

Before any glove specification is finalised, the question must be asked directly: can this exposure be removed rather than protected against? Options include distance, no-touch tools, automation, mechanical handling, isolation, guarding, fixtures, improved work positioning, and process redesign. Only exposure that survives this stage proceeds to Stage 5.

Stage 5 — Protect Residual Interaction

Glove selection is the final stage, not the first. At this point, the specification is built from the residual exposure profile established in Stages 1–4: required impact performance, cut level, abrasion resistance, puncture resistance, palm material, grip condition, dexterity requirement, cuff design, fit, expected wear duration, and environmental conditions.

Section 07 — Construction

What an impact glove is actually built from

An impact glove is a system of components engineered to work together, not a single material applied uniformly to a glove shape. Understanding the individual elements clarifies why two gloves with similar visual coverage can perform very differently in the field.

Component	Function
Dorsal impact protection	Rigid or semi-rigid material over the back of the hand, absorbing and dispersing blunt-force energy away from bone.
TPR geometry	The shape, thickness and segmentation of thermoplastic rubber elements; determines force dispersion and flexibility.
Segmented protection	Discrete impact zones rather than one continuous shell, allowing the hand to flex at the knuckles.
Flex zones	Engineered gaps or thinner material between segments, permitting natural hand movement.
Finger articulation	Pre-curved or segmented finger construction that reduces resistance when gripping.
Knuckle coverage	Targeted protection over the most impact-vulnerable bony prominence on the hand.
Fingertip protection	Reinforcement at the point of highest dexterity demand and frequent crush exposure.
Metacarpal coverage	Protection across the back-of-hand long bones, often the largest single impact zone.
Thumb protection	Independent coverage reflecting the thumb's distinct range of motion and exposure pattern.
Sidewall coverage	Protection against lateral pinch and glancing contact, often absent from basic impact gloves.
Palm construction	Material selection for grip, abrasion resistance and durability under load-bearing contact.
Thumb-saddle reinforcement	Reinforced material at the high-wear junction between thumb and palm.
Cuff design	Closure and length determining debris ingress protection and ease of don/doff.
Seam architecture	Stitch placement and reinforcement at points of greatest mechanical stress.
Liner construction	Inner material affecting comfort, moisture management and wear duration.

Visual coverage alone is not a reliable indicator of protective performance. A glove can appear heavily armoured while leaving gaps in continuity between impact elements that allow force to transmit directly to bone at the seams. What matters in practice is the engineered relationship between these components:

• Protection continuity — whether impact elements work as a connected system or leave unprotected gaps between segments
• Attachment quality — how securely TPR or composite elements are bonded to the glove shell, and their resistance to detachment under repeated flexing
• Flexibility — whether the protective elements restrict natural hand movement enough to affect task performance
• Weight and bulk — added mass and thickness that may reduce dexterity or increase fatigue over a shift
• Worker comfort — a critical and frequently underweighted factor, since a glove that is removed due to discomfort provides no protection at all

Section 09 — Product Platform

KONG® as a family of task-specific gloves, not a single product

KONG® is presented in this whitepaper as a platform of distinct glove models, each engineered for a different point on the exposure spectrum described in Sections 2 and 3. This section focuses on two models with clearly differentiated exposure profiles: KONG® Original SDX2 and KONG® Deck Crew KDC5. Specifications below are drawn from current Ironclad product technical data sheets.

KONG® Original SDX2 — balanced heavy-duty impact protection

SDX2 is built around general impact exposure across heavy industrial and oilfield tasks where dorsal protection, durability and dexterity all matter, but extreme cut or abrasion resistance is not the dominant requirement. Construction features a double-layer synthetic leather dotted palm for all-purpose durability, a breathable nylon back-of-hand, and patented full-coverage TPR protection across the fingers, thumb, knuckle and metacarpal.

Specification	SDX2
ANSI/ISEA 105 cut level	A2
EN 388:2016 rating	4242AP (abrasion 4 / cut 2 / tear 4 / puncture 2 / ISO cut letter A / impact-tested)
ANSI/ISEA 138 impact level	2
EN 407 thermal rating	X1XXXX
Peak impact protection	3X 150:50  ·  5X 500:100  ·  5X 375:75
Grip rating — dry / wet / oily	5★ / 5★ / 3★
Palm construction	Double layer synthetic leather, dotted
Back of hand	Breathable nylon
Cuff	Slip-on
Sizes	S – XXXL

This profile suits tasks where the hand is repeatedly exposed to blunt impact and struck-by risk during general handling — rig-floor tool use, equipment handling, and broad maintenance work — without the combined heavy-abrasion and high-cut demands addressed by KDC5 below.

KONG® Deck Crew KDC5 — combined cut, abrasion and impact protection

KDC5 is built for tasks where impact exposure is combined with severe cut and abrasion risk — sharp steel edges, wire rope, tubular handling, rigging hardware, and heavy maintenance. The palm uses a 4-layer Armortex® high-abrasion construction with a cut-resistant liner made with DuPont™ Kevlar®, paired with the same patented KONG® impact protection across fingers, thumb, knuckle and metacarpal. An Armortex®-reinforced thumb saddle addresses a known high-wear failure point identified in Section 13, and the shell is treated with DuPont™ Teflon™ for water and oil repellency.

Specification	KDC5
ANSI/ISEA 105 cut level	A7
EN 388:2016 rating	4X44FP (abrasion 4 / cut not assigned [X] / tear 4 / puncture 4 / ISO cut letter F / impact-tested)
ANSI/ISEA 138 impact level	2
EN 407 thermal rating	X2XXXX
Peak impact protection	3X 150:50  ·  5X 500:100  ·  5X 375:75
Grip rating — dry / wet / oily	5★ / 5★ / 4★
Palm construction	4-layer Armortex® high-abrasion, Kevlar® cut-resistant liner
Shell treatment	DuPont™ Teflon™ water/oil repellent
Cuff	Slip-on
Sizes	S – XXXL

Ironclad's published industry guidance for KDC5 lists oil and gas drilling, extraction and refining, fracking, mining, demolition, heavy construction, rigging, and tool pushing as primary applications — consistent with the combined cut, abrasion and impact exposure typical of those environments.

Selecting between SDX2 and KDC5

Both gloves carry the same ANSI/ISEA 138 Level 2 impact rating — the differentiator is not impact performance but the cut, abrasion and puncture profile beneath it. The selection question is not "which is the better glove" but "which exposure profile matches the task," consistent with the Stage 5 logic in Section 5.

Exposure or Task Requirement	SDX2	KDC5	Selection Consideration
General impact handling	✓	✓	Both rated ANSI/ISEA 138 Level 2 — equivalent at this layer
Higher cut exposure	A2	A7	KDC5 for sharp steel, blade contact, wire strand
Heavy abrasion	–	✓	KDC5's Armortex® palm suited to sustained abrasive contact
Dexterity-sensitive work	✓	–	SDX2's lighter palm construction favours fine task work
Wet or oily handling	3★ oily	4★ oily	KDC5 rated higher for oily-grip retention
Rigging hardware	✓	✓	Confirm cut exposure level present at point of contact
Tubular handling	–	✓	KDC5 for direct contact with tubular threads and edges
Maintenance tools	✓	✓	Either, depending on surrounding cut/abrasion exposure

This comparison should be read alongside an actual task assessment using the framework in Section 5 — the table identifies which exposure dimension each glove is engineered to address, not a universal ranking of one model over the other.

Section 10 — Sector Application

Applying the framework across five industrial sectors

The five-stage framework in Section 5 produces different residual exposure profiles depending on the sector and the specific task. The mappings below illustrate the framework applied to representative tasks — they are starting points for a site-specific assessment, not substitutes for one.

Oil and Gas

Representative tasks: drill-floor operations, tubular handling, slips and tongs, rigging, maintenance, offshore deck work, valve and pipeline activities.

Assessment Dimension	Typical Profile

Cut and abrasion exposure	High — sharp threads, wire rope, steel edges
Grip conditions	Frequently wet, oily, or both
Engineering-control opportunity	Tag lines, mechanical tongs, positioning aids, no-touch handling tools
Residual glove requirement	Combined impact, cut, abrasion and oily-grip performance
Field-validation requirement	Trial under actual rig-floor wet/oily conditions, not bench conditions

Mining

Impact source	Component contact, tool strikes, struck-by during handling
Cut and abrasion exposure	High — sheared and machined edges
Grip conditions	Dry to lightly oiled, dependent on process stage
Engineering-control opportunity	Edge deburring at source; mechanical lifting for plate handling; fixtures for assembly alignment
Residual glove requirement	Cut-resistant palm with dorsal impact protection for tool and component contact
Field-validation requirement	Trial across representative assembly and maintenance tasks separately

Shipyards

Representative tasks: heavy steel work, rigging, mechanical maintenance, confined-space work, abrasive surfaces.

Assessment Dimension	Typical Profile
Hand interaction	Sustained contact in confined and awkward working positions
Impact source	Structural steel contact, tool use, rigging hardware
Cut and abrasion exposure	High — corroded and cut steel surfaces
Grip conditions	Variable; often dusty or oily depending on work area
Engineering-control opportunity	Improved access planning to reduce confined-space hand exposure; mechanical aids for rigging tasks
Residual glove requirement	High cut and abrasion resistance with dexterity sufficient for confined-space work
Field-validation requirement	Trial specifically in confined-space conditions where dexterity loss is most consequential

Section 12 — Validation

A structured process for trialling a glove before standardising on it

A rating sheet confirms laboratory performance. A field trial confirms whether the glove performs for the specific task, worker population, and environment it will actually be used in. Skipping this step is one of the most common causes of poor glove adoption — and of gloves being removed mid-shift, which eliminates whatever protection they were providing.

Before the Trial

Record baseline information that will be needed to interpret trial results:

• Task being performed
• Exposure profile established using the Section 5 framework
• Current glove in use, if any, and known issues with it
• Worker group participating in the trial
• Sizes required across the group
• Environmental conditions — temperature, wet/dry/oily, dust
• Expected wear period for the trial

During the Trial

Monitor performance across the dimensions that determine whether a glove will actually be worn and will actually protect:

• Grip performance under task conditions
• Fit across the worker group
• Dexterity for task-specific manipulation
• Comfort over a full shift
• Heat build-up and sweating
• Palm wear progression
• Seam wear and integrity
• TPR or impact-element damage
• Thumb-saddle condition
• Worker behaviour — including whether the glove is removed during the task, and when
• Glove removal — frequency and stated reason

At the End of the Trial

Record outcomes needed for a standardisation decision:

• Number of working days the glove remained serviceable
• Reason for withdrawal, if withdrawn before expected end of life
• Worker feedback, gathered directly rather than inferred
• Failure location, if failure occurred
• Cost per working day, calculated per Section 14
• Suitability for continued use as standard issue
• Whether a different model is indicated
• Whether the trial revealed a need for an engineering control rather than a different glove

Section 14 — Cost Analysis

Why purchase price alone is an inadequate basis for comparison

Comparing gloves on purchase price per pair treats them as interchangeable commodities. They are not. A lower-priced glove that fails in half the working days, or that workers remove due to poor fit or comfort, can cost more per day of actual protection than a higher-priced glove that is worn for its full service life.

This single metric, properly tracked through the field trial process in Section 12, surfaces information that price-per-pair comparison hides. Factors that influence the real figure include:

• Replacement frequency under actual task conditions, not catalogue-rated service life
• Worker acceptance — a glove that is comfortable and well-fitted is worn longer and more consistently
• Glove utilisation — whether the glove is actually worn during the exposure window, or removed
• Premature disposal due to fit, comfort, or task mismatch rather than genuine wear-out
• Inventory complexity from carrying too many models or sizes, increasing the chance of mis-issue
• Injury severity and its downstream cost if the wrong glove is selected to save on unit price
• Lost time from injury, glove-related task interruption, or re-fitting
• Productivity interruption caused by gloves that restrict necessary dexterity
• Procurement consistency — standardising on validated models versus ad hoc purchasing
• The cost of overspecification — paying for protection levels beyond what the task requires
• The cost of underspecification — the larger and more serious cost, carrying injury and compliance risk

This whitepaper does not assert that any specific glove or specification produces a defined cost saving. The cost-per-working-day method is presented as a measurement tool: it allows a programme to compare options on a consistent basis, using data generated by its own field trials rather than supplier claims.

Section 16 — Category Development

Building awareness before demand could exist

PSC introduced KONG® to the Indian market in 2008, at a point when impact protection was not yet a widely recognised glove category among Indian industrial buyers. Where cut-resistant and general-purpose gloves were established and well understood, dedicated back-of-hand impact protection had no existing reference point in most buyers' purchasing frameworks.

This required a different kind of market entry than introducing a new model within an established category. PSC's early work centred on:

• Early market education — explaining what back-of-hand impact exposure was, and why it was distinct from the cut and abrasion exposure most buyers were already managing
• Demonstrations — showing the construction and function of impact protection directly, since the category had no existing reference point
• Site engagement — working directly with oilfield and industrial sites to understand task-level exposure rather than presenting a generic product pitch
• Oilfield applications — building initial category presence in the sector where the exposure case was most immediately visible
• Back-of-hand injury awareness — surfacing a hazard category that safety programmes had often not formally tracked separately from general hand injury
• Resistance to premium glove pricing — working through buyer resistance to a price point well above commodity general-purpose gloves, by connecting it to the specific exposure it addressed
• Transition toward task-specific selection — moving buyers from single-glove-for-all-tasks purchasing toward exposure-matched selection
• Long-term category development — sustaining this positioning over time rather than treating it as a one-time product launch

This history positions PSC's role in the Indian market specifically as category-development work, not as one distributor competing with others on an already-understood product. The same task-mapping orientation that shaped this early market education underlies the framework presented throughout this whitepaper.

Section 18 — Closing

From general-purpose covering to engineered protection

Impact-protection gloves represent a meaningful evolution in industrial hand safety — from hand covering selected primarily for grip and basic durability, to engineered protection matched against a specific, mapped exposure profile. That evolution is not complete. It depends on the discipline with which it is applied, task by task, on every site that adopts it.

The future of effective hand safety programmes will depend less on the emergence of new glove materials and more on the rigour of the process around glove selection:

• Better task analysis, conducted before any product is considered
• Better exposure mapping, identifying precisely where and how the hand is at risk
• More effective engineering controls, applied ahead of PPE wherever feasible
• More precise glove selection, matched to residual exposure rather than habit or price
• Better worker trials, generating real field data rather than relying on supplier claims
• Stronger collaboration between HSE, operations and procurement, so that specification, purchasing and field reality stay aligned

Impact Glove Inspection Checklist

For use at defined intervals to catch wear and failure patterns described in Section 13 before they result in loss of protection.

Inspection Point	Pass	Fail / Note
Fingertip condition — no excessive wear or thinning	☐
Palm condition — no holes, excessive thinning	☐
Thumb-saddle integrity — no separation or tearing	☐
Seams intact — no rupture or open stitching	☐
TPR / impact elements — securely attached, no separation	☐
Cuff condition — closure functional, no tearing	☐
Shell condition — no excessive oil saturation	☐
Material flexibility — no hardening or stiffening	☐
Grip surface — no smoothing or loss of texture	☐
No visible cut penetration through palm liner	☐
Overall fit — still correctly sized for wearer	☐

Any single "fail" result should trigger replacement rather than continued use pending further wear — the inspection point exists because that specific failure mode has a known link to reduced protection.
