Hand protection means selecting gloves that match the specific hazard the hands face. OSHA's standard, 29 CFR 1910.138, requires employers to choose appropriate hand protection when hands are exposed to cuts, chemicals, abrasions, punctures, burns, or skin absorption. Cut resistance is graded A1 to A9 under ANSI/ISEA 105.
Hands take a beating in manufacturing, and hand injuries sit near the top of the recordable-injury list for good reason: hands are in the work. The fix is rarely "wear gloves" in the abstract. It is wearing the right glove for the hazard, and knowing the one situation where a glove makes things worse. This post covers the selection duty, how to read the cut-level rating, matching gloves to each hazard type, and the rotating-machinery caution. It is educational, not legal advice.
What does OSHA require for hand protection?
OSHA's hand protection standard, 29 CFR 1910.138, is short and puts the duty on the employer: select and require appropriate hand protection when employees' hands are exposed to hazards such as skin absorption of harmful substances, severe cuts or lacerations, severe abrasions, punctures, chemical burns, thermal burns, and harmful temperature extremes. The standard does not name specific gloves. It requires you to base the selection on an evaluation of the tasks and the hazards, which is why a real hand-protection program starts with a hazard assessment, not a glove catalog.
That assessment is the same discipline as any other PPE decision. You look at each task, list the ways a hand could be hurt, and pick protection that addresses those specific ways without creating a new hazard. Hand protection is one line in a broader PPE program, and it only works when the glove on the hand matches the assessment on paper.
The standard also expects the protection to be based on more than a guess. Fit, dexterity, and the ability to do the task safely all figure into the selection, because a glove that is technically rated for the hazard but too clumsy to work in creates its own problems. That is why two people doing the same nominal job, one running a blade and one handling warm parts, may need different gloves, and why a program that issues one glove to the whole plant is almost always wrong for somebody.
How do you read ANSI/ISEA 105 cut levels?
Cut resistance is rated on a nine-step scale, A1 through A9, defined by the ANSI/ISEA 105 standard. The number is set by a lab test: a blade under a measured load is drawn across the glove material, and the rating reflects the grams of force needed to cut through. A1 is the lightest protection; A9 is the highest. Higher is not automatically better, because the heaviest cut gloves sacrifice dexterity, and a glove too clumsy for the task gets pulled off, which protects nothing.
Cut is only one property ANSI/ISEA 105 rates. The same standard also covers puncture, abrasion, and other performance measures, so a glove can carry several ratings at once. When you read a glove spec, the cut level is the headline number, but the abrasion and puncture ratings matter just as much for the actual task.
The rating is also only good while the glove is intact. A cut-level A5 glove that is worn thin at the fingertips, soaked with oil, or has a hole in the palm no longer performs at A5, and workers keep wearing gloves long past that point because a glove looks fine from the back of the hand. Build a simple inspect-and-replace habit into the job: check the palm and fingertips, look for cuts, thinning, and chemical swelling, and swap the glove on a schedule rather than waiting for it to fail on a sharp edge. A worn glove gives a false sense of protection, which is worse than a bare hand because the worker trusts it.
How do you match the glove to the hazard?
You start from the hazard, not the glove. Each hazard type points to a different material and a different property, and many jobs combine several, which is why glove selection is a matching exercise rather than a single choice.
| Hazard | What it does to a hand | What to look for in a glove |
|---|---|---|
| Cut / laceration | Slices from blades, sheet metal, glass, knives | ANSI/ISEA 105 cut level matched to the sharpness and force |
| Puncture | Wire, needles, splinters, staples piercing the palm | Puncture rating; note needlestick is rated separately from probe puncture |
| Abrasion | Wearing skin raw on rough stock or surfaces | Abrasion rating and a durable coating or leather |
| Chemical | Burns and absorption through the skin | Material rated for the specific chemical and breakthrough time; check the SDS |
| Heat / cold | Thermal burns or cold injury | Thermal or contact-heat rating; insulation for cold work |
Two rules keep this honest. First, chemical resistance is chemical-specific: a glove that shrugs off one solvent may dissolve in another, so match the glove material to the chemical and its breakthrough time using the chemical's safety data sheet, not a general "chemical glove" label. Second, fit and dexterity are part of protection. A glove that is too bulky to do the task, or too hot to keep on, ends up in a pocket, and no rating protects a bare hand.
Why can gloves be dangerous around rotating machinery?
Because a glove can be grabbed by a moving part and pull the hand in with it. This is the exception that surprises people who think more glove is always safer. Near rotating shafts, spindles, drills, lathes, augers, conveyors, and any rotating tooling, a glove that catches does not tear away cleanly the way skin might; it drags the hand into the pinch point. For that reason, many machine operations specifically prohibit gloves, and the real control is guarding the rotating part, not gloving the hand.
This is where hand protection and machine guarding intersect. A hazard assessment that flags rotating tooling should push the decision up the hierarchy of controls toward guarding and, where a machine is serviced, toward lockout/tagout so the part is not rotating at all during a hands-in task. Gloves are personal protective equipment, near the bottom of that hierarchy; they protect the individual but do not remove the hazard.
None of that makes gloves optional. It means gloves are the layer you keep after you have done everything higher up, not the first thing you reach for. The same logic runs through the rest of the PPE program, whether the exposed body part is the hands or, with a hard hat, the head, which is why hand protection and head protection follow the same selection discipline.
How do you build a hand-protection program?
Run it as a repeatable loop tied to the hazard assessment, not a one-time glove order.
- Assess each task for hand hazards. List every way a hand could be cut, punctured, abraded, burned, or exposed to chemicals during the job, drawing on your hazard identification and job safety analysis.
- Rank the hazards by severity and how often the hand is exposed, so you match the protection to the real risk rather than the worst imaginable case.
- Select gloves by property, using the ANSI/ISEA 105 cut level for cut hazards and the correct chemical material and breakthrough time for chemical hazards, checking dexterity and fit for the actual task.
- Flag the no-glove zones. Identify rotating-machinery tasks where gloves are prohibited and drive those to guarding and lockout instead.
- Train and fit workers on which glove goes with which task, how to inspect it, and when to replace it.
- Inspect and reassess when a process, material, or tool changes, and whenever hand injuries or near misses point at a gap.
Track the outcome. Hand injuries that keep landing on the log at the same operation are telling you the glove is wrong for the task or the task needs a different control, and they show up directly in your recordable injury rate.
What do the standards say?
The primary sources behind hand protection:
- OSHA's hand protection standard, 29 CFR 1910.138 requires employers to select appropriate hand protection based on the hazards of the task.
- OSHA's general PPE requirements, 29 CFR 1910.132 require a hazard assessment to determine what PPE is needed.
- The cut, puncture, and abrasion ratings come from the ISEA consensus standard ANSI/ISEA 105, which defines the A1-to-A9 cut scale and the TDM-100 test method.
Bureau of Labor Statistics injury data consistently shows hands and fingers among the most frequently injured body parts in manufacturing, which is why the selection duty carries weight.
Where the glove program drifts
The assessment gets done once, the gloves get ordered, and then the job changes and nobody revisits the choice. New stock is sharper, a line adds a rotating tool, a chemical gets swapped for one the glove does not resist, and the paperwork still says the old glove is fine. Harmony is an AI-native layer that connects machines, software, and paperwork into one operational layer, with no rip-and-replace, so the hazard assessment, the glove specification, and the training record for a task stay attached to the task instead of scattered across binders. AI search returns cited answers across those records, so a supervisor can pull the required glove and its cut level for a given operation in seconds, part of everyday connected worker technology. When a process or material changes, Harmony's workflow platform routes the reassessment to the person who owns it, so a swapped chemical or a new rotating tool triggers a fresh glove decision instead of an injury. It is not PPE; it keeps the PPE decision from going stale.
