ANSI ISEA 138 explained simply: it is the impact-glove standard for back-of-hand protection, especially knuckles, fingers, and thumbs. Level 1 means basic impact protection, Level 2 suits regular tool and material handling risk, and Level 3 is for higher-impact exposure. Buyers should match the level to the task, then confirm cut rating, grip, fit, and test evidence.
A glove can look tough and still fail the job. Thick back-of-hand padding does not tell a safety lead how much impact force reaches the knuckles. ANSI/ISEA 138 gives buyers a cleaner way to compare impact-resistant gloves. For oil and gas teams, metal handlers, mechanics, and mining crews, the real question is simple: which level protects the hand without making the glove too bulky to wear?
ANSI/ISEA 138 measures how well impact-resistant gloves reduce force to the back of the hand, especially knuckles and fingers. It does not replace cut, puncture, chemical, grip, or heat ratings.
ANSI/ISEA 138 is an impact protection standard for occupational gloves. It focuses on dorsal hand protection, which means the back of the hand. The standard covers areas that often get hit during tool handling, pipe work, metal handling, construction, mining, and equipment maintenance.
The official ANSI/ISEA 138 standard sets requirements for testing, classifying, and labeling gloves that claim back-of-hand impact protection. That makes it useful for buyers who need a measurable rating instead of a vague “impact resistant” claim.
ANSI/ISEA 138 is not a cut standard. Cut protection is a separate buying question, usually tied to blade, sheet metal, glass, or sharp-edge hazards. If your team also needs cut protection, use a broader cut glove selection process with the impact rating.
Think of ANSI/ISEA 138 as one layer in the glove spec. It answers, “How much blunt impact reaches the back of the hand?” It does not answer, “Will this glove resist sharp metal, oil, chemicals, heat, or repeated washing?”
Buyers needed ANSI/ISEA 138 because “impact resistant” was easy to claim but hard to compare. The standard turns back-of-hand protection into tested levels, so safety teams can specify gloves by measured performance.
Before this standard, many gloves used thermoplastic rubber, often called TPR, across the back of the hand. Some designs looked aggressive, but visual padding alone did not give buyers a fair comparison. One glove could have large bumpers and poor force reduction. Another could look slimmer and perform better.
This matters because employers must choose hand protection based on workplace hazards, task conditions, duration of use, and the type of protection needed under OSHA hand protection rules. ANSI/ISEA 138 helps turn that duty into a clearer glove specification.
Here is the buyer rule: treat thick TPR as a design feature, not proof of protection. If the glove is not marked and supported by test evidence, do not treat it as a verified impact glove.
The test simulates a blunt strike by dropping a controlled mass onto protected back-of-hand zones and measuring force that passes through the glove. Less transmitted force means the glove absorbed or spread more impact energy.
In simple terms, the lab test asks one question: when something hits the back of the glove, how much force still reaches the hand? The glove is positioned over a curved test surface, then a controlled impact is applied to key back-of-hand zones.
Competitor explainers from Uvex and Magid describe the test as a way to measure transmitted force through the glove. That is the number buyers care about. Lower transmitted force means stronger impact attenuation.
The practical picture is easy. Imagine a worker’s knuckle hitting pipe, a wrench slipping, or a hand getting struck against steel equipment. The standard does not copy every jobsite accident. It creates a controlled way to compare how well gloves reduce force in the impact zones.
ANSI/ISEA 138 Level 3 is the highest impact rating because it allows the least force through the glove. Level 1 is lighter-duty impact protection, Level 2 is mid-range, and Level 3 is for higher-impact exposure.
The level number does not mean how hard the glove was hit. It shows how much force passed through the glove during testing. That can confuse buyers at first. A lower transmitted-force number means better protection because less force reaches the hand.
The ANSI Blog explanation gives the common Level 1, 2, and 3 force thresholds used to classify impact gloves. For buyers, the main point is simple: higher level, lower force allowed through the glove.
| ANSI/ISEA 138 level | Average transmitted force | Buyer meaning | Best-fit use case |
|---|---|---|---|
| Level 1 | 9 kN or less | Basic back-of-hand impact protection | Occasional bumps and light material handling |
| Level 2 | 6.5 kN or less | Moderate impact protection | Regular tool, pipe, metal, and equipment handling |
| Level 3 | 4 kN or less | Highest impact protection | Severe or frequent impact exposure |
The glove’s overall rating can be limited by the weaker tested area. If the knuckle area performs well but the fingers perform worse, the final rating should reflect that weaker zone. MSC’s explanation makes this point useful for buyers: full-hand impact performance matters, not only the most padded area.
The right level depends on the task, not the job title alone. Oil and gas crews often start at Level 2 for general handling, then move to Level 3 for high-impact tasks around pipe, valves, heavy iron, hammers, and pinch points.
Use this matrix as a starting point for glove trials. It should not replace a site hazard assessment, but it helps safety leads avoid one lazy spec for every worker.
| Trade or task | Main impact hazard | Likely starting level | Move up when | What else to specify |
|---|---|---|---|---|
| Oil and gas pipe yard | Pipe, couplings, valves, heavy tools | Level 2 | Frequent pinch, crush, or struck-by exposure | Cut rating, oily grip, cuff fit |
| Rig maintenance | Oily tools, equipment edges, metal parts | Level 2 | Hands work near heavy moving parts | Oil grip, dexterity, abrasion resistance |
| Mining or heavy equipment repair | Pins, buckets, hammers, heavy components | Level 3 | High-force impact is frequent | Dexterity trial, cut rating, fit |
| Construction demolition | Tools, debris, rough materials | Level 2 | Repeated heavy strikes or pinch risk | Abrasion, cut, puncture resistance |
| Sheet metal fabrication | Panels, fixtures, sharp edges | Level 1 or 2 | Back-of-hand bumps happen often | Link impact choice with sheet metal gloves |
| Warehouse material handling | Pallets, racks, cartons, straps | Level 1 or 2 | Frequent rack or pallet strikes | Grip, abrasion, comfort |
| Automotive repair | Tools, parts, engine bay contact | Level 1 or 2 | Tight spaces create knuckle strikes | Dexterity, oil grip, thin palm |
A pipe-yard worker and a warehouse picker should not always wear the same impact level. One glove level for an entire site is usually poor specification. Match the level to the hazard, then test whether workers can still grip, feel, and move well enough to keep the glove on.
Level 3 is not automatically the best glove for every job. It is best when impact risk is severe, but Level 2 may be the better specification when dexterity, grip, and all-shift wear matter more.
Level 3 gives the highest impact attenuation in this rating system. That makes it attractive for mining, heavy equipment work, rig maintenance, and high-risk pipe handling. But higher impact protection can come with more back-of-hand structure, depending on the glove design.
The buying mistake is simple: choosing the highest level before checking the job. A glove that workers remove because it feels bulky is a failed safety spec. For moderate impact risk, Level 2 may protect well enough and support better all-shift wear.
D3O’s FAQ-style guide raises the same kind of buyer concern around Level 3 and dexterity. Material, bumper design, glove gauge, and fit all affect how the glove feels in use.
For an oil and gas safety lead, the better rule is this: assign Level 3 to severe impact tasks, not every hand on the site. Then use Level 2 where workers need more finger control, tool feel, and grip. Material choice also matters, so compare options such as HPPE vs Kevlar when cut protection is part of the same spec.
The impact level is only one line in a complete glove spec. Buyers should also specify cut resistance, grip, coating, fit, washability, and task-specific exposure. OSHA’s hand protection rule expects glove choice to match actual workplace hazards, not one rating alone.
Use this checklist before issuing a purchase order:
Wash care matters more than many buyers expect. If a glove loses shape, grip, or fit after cleaning, the impact design may not sit correctly on the hand. For reusable programs, check whether the glove belongs in a washable cut gloves workflow before scaling it across teams.
Buyers should verify the marked ANSI/ISEA 138 level, request supporting test documentation, and confirm accredited-lab testing. Do not accept thick-looking back-of-hand padding as proof of impact performance.
Start with the glove marking. A compliant product should make the impact level clear, usually through a pictogram or rating mark. Then ask the supplier for documentation that supports the Level 1, 2, or 3 claim.
D3O notes that the standard created a clearer way for end users to keep suppliers honest, including attention to testing and lab requirements. The brief also identified ISO/IEC 17025:2017 accredited-lab testing as a key verification point from the fetched source set.
| Verification step | What to ask | Why it matters |
|---|---|---|
| Rating mark | Is the glove marked to ANSI/ISEA 138? | Confirms the supplier is making a clear standard claim |
| Level number | Is it Level 1, Level 2, or Level 3? | Prevents vague “impact resistant” wording |
| Test evidence | Can the supplier provide test documentation? | Supports procurement and audit records |
| Lab credibility | Was testing done by an accredited lab? | Reduces risk of weak or unsupported claims |
| Coverage check | Do bumpers cover knuckles, fingers, and thumb zones? | Poor placement can reduce real job protection |
| Field trial | Can workers grip, move, and keep the glove on? | Good lab performance still needs jobsite acceptance |
Do not skip the field trial. A glove may pass testing but fail the job if the bumper placement does not match the worker’s hand, or if the palm coating slips on oily pipe and tools.
An oil and gas glove spec should name the ANSI/ISEA 138 level by task, then pair it with cut rating, grip, coating, fit, and trial requirements. Do not write “impact resistant gloves” without a level.
For general pipe yard handling, Level 2 is a strong starting point when workers face regular bumps, tool strikes, and moderate pinch risk. For heavy iron, hammering, equipment repair, and frequent struck-by hazards, Level 3 may be the right requirement if workers can still perform the task safely.
“Impact-resistant work gloves shall be marked to ANSI/ISEA 138 Level 2 or higher for general pipe, valve, and equipment handling. Tasks with frequent high-impact or pinch exposure shall be evaluated for Level 3. Gloves must also meet the required cut rating, provide secure grip in oily conditions, and pass a worker fit and dexterity trial before approval.”
This wording gives procurement a standard to buy against. It also gives the safety team room to separate general handling from severe impact tasks. For broader glove selection beyond impact, send the reader back to the cut resistant glove guide.
ANSI ISEA 138 explained well should lead to one buying action: match the impact level to the task before choosing a glove model. Start with your highest-risk jobs, such as pipe handling, rig maintenance, mining repair, or sheet metal work. Decide whether Level 1, 2, or 3 fits the exposure, then verify the marking and test support.
After that, run a short field trial. Check grip, cut protection, fit, and worker acceptance. The best glove is not the one with the biggest bumper. It is the one that protects the hand and stays on during the real job.
ANSI/ISEA 138 is the American impact-resistance standard for gloves that protect the back of the hand. It classifies gloves by how much force passes through the glove during impact testing, especially around knuckles, fingers, and thumbs.
Levels 1, 2, and 3 show increasing impact protection. Level 1 is the lowest impact rating, Level 2 is mid-range, and Level 3 allows the least transmitted force through the glove during testing.
No, ANSI/ISEA 138 is not the same as cut resistance. It measures back-of-hand impact protection, while cut ratings measure how well a glove resists blades, sharp edges, or cutting hazards.
Level 3 gloves may feel bulkier in some designs, but material and bumper geometry matter. Buyers should test dexterity, grip, and worker acceptance before specifying Level 3 across every job or department.
Impact performance depends on both material and design geometry. Thick TPR alone is not proof of ANSI/ISEA 138 performance unless the glove is tested, marked, and supported by reliable documentation.
Buyers should ask for the ANSI/ISEA 138 level marking, test documentation, and proof of accredited-lab testing. They should also trial the glove to confirm bumper placement over knuckles, fingers, and thumbs.
ANSI/ISEA 138 is a voluntary consensus standard, not a general OSHA regulation by itself. OSHA still requires employers to choose hand protection based on workplace hazards, task conditions, and the type of protection needed.
