Industrial workers may handle acids, alkalis, solvents, oils and cleaning agents. No single glove material provides suitable protection against every chemical. The appropriate choice depends on the substance, concentration, exposure conditions and tested performance of the individual model. Chemical protection, liquid coverage and oily handling grip are different requirements. This guide explains how to evaluate them, interpret EN ISO 374 and compare glove constructions. Explore our Chemical Resistant Gloves Worksite Solution for an overview of industrial applications.
ommon Chemical Hazards During Handling
Chemical-handling tasks can involve several types of exposure. The following considerations help identify the protection needed; they do not establish whether a particular glove is suitable.
Chemical Splash
Oil & Solvents
Skin Irritation
Liquid Penetration
Depending on the substance and concentration, chemical splashes may cause skin irritation or burns.
Some oils and solvents may irritate the skin or degrade certain glove materials.
Repeated or prolonged contact with some substances may contribute to dryness, irritation or dermatitis.
Liquids may enter through holes, tears or other defects in a glove.
How to Choose Chemical Gloves by Application
Read the chemical’s safety data sheet and identify the formulation, concentration, temperature and likely contact duration. Use manufacturer compatibility data for the exact glove model.
Application
Main concern
What to check
Chemical processing
Contact with process substances
Chemical-specific test data
Industrial cleaning
Splash and repeated wetting
Cleaner formulation, coverage and compatibility
Maintenance
Oils, liquids or chemicals
Actual substance before glove selection
Oil handling
Grip and liquid contact
Oil composition and required barrier performance
Chemical transfer
Contact duration and splash
Permeation, degradation and glove construction
Select for the substance being handled, rather than the words “nitrile,” “PVC” or “chemical resistant.” Data for one chemical may not establish suitability for a mixture.

What Does EN ISO 374 Mean for Chemical Gloves?
The EN ISO 374 series addresses protection against dangerous chemicals and microorganisms. Part 1 defines chemical-performance requirements; microorganism claims are assessed separately under Part 5.
Type A, B and C classify performance against specified test chemicals:
Classification
Minimum permeation performance
Number of listed test chemicals
Type A
Level 2
At least six
Type B
Level 2
At least three
Type C
Level 1
At least one
Chemical letters identify particular test substances. For example, J means n-heptane, K sodium hydroxide 40%, and L sulfuric acid 96%. A JKL marking does not cover all solvents, acids or alkalis.
These classifications describe laboratory performance, not universal compatibility or a guaranteed wearing time. Check the chemical-specific results and instructions. Review mechanical requirements separately through our EN 388 glove ratings guide.
Permeation, Penetration and Degradation: What’s the Difference?
Permeation
The chemical passes through glove material at a molecular level. It can occur without visible holes or damage. Laboratory breakthrough time is not automatically a safe workplace contact time.
Penetration
Liquid enters through pinholes, seams, defects or other openings. Inspecting a glove helps identify obvious damage, but does not replace appropriate testing.
Degradation
Chemical contact changes the material’s physical properties, potentially causing swelling, softening, hardening or cracking. A glove may remain visibly intact while its performance changes.
Review all relevant data for the intended chemical and exposure. Workplace temperature, movement and wear can differ from laboratory conditions. Follow model-specific instructions for inspection, removal, replacement and any permitted reuse.
Before work, establish how contaminated gloves will be removed and replaced. Cleaning or reuse requires applicable manufacturer instructions. Visual inspection alone cannot confirm that a chemically exposed glove retains its original protective performance.
Nitrile or PVC: Which Is Better for Chemical Handling?
Neither material is universally better. Nitrile chemical gloves and PVC chemical gloves can perform differently against particular substances, concentrations and contact conditions. Thickness, construction and the tested formulation also matter.
A nitrile-coated knitted work glove is not equivalent to an unsupported nitrile gauntlet. Similarly, a full PVC coating does not by itself establish chemical compatibility. Compare the exact model’s data, then check coverage, fit and required hand movements.
Safeyear Glove Options to Assess for Different Handling Tasks
GSP0211R — PVC Gauntlet and Chemical-Data Review
GSP0211R PVC Gloves feature fully coated PVC construction and a cotton interlock liner. For tasks requiring chemical protection, request current model-specific chemical test data, certification and instructions before approval. Match the documents to the supplied configuration and actual substance.
LoraVex™ Chemical Protection provides the related technology context. A technology name does not substitute for verified model-specific evidence.
FL-0056 — Liquid-Handling Construction
FL-0056 Nitrile Gloves use unsupported nitrile construction, a flocked liner and an extended cuff. These construction features can be assessed for liquid-handling coverage. Do not infer EN ISO 374 certification or hazardous-chemical suitability from the material or product name.
FD1289 — Industrial Handling and Grip
FD1289 Coated Work Glovescombine nitrile coating with a textile liner for industrial handling. Consider GripVanta™ Grip Technology as supporting information. Handling grip and mechanical performance do not establish chemical permeation resistance.
Different constructions require different task-specific evidence; these are not interchangeable protection claims.
Chemical Glove Selection Checklist
☐ What chemical will be handled? ☐ What is the chemical concentration? ☐ Is exposure splash, intermittent or prolonged? ☐ How long may the glove contact the chemical? ☐ What chemical test data is available for the glove? ☐ Is grip or mechanical protection also required? ☐ Does the glove provide suitable coverage and fit?
Chemical Handling Gloves FAQ
What gloves are best for chemical handling?
There is no single best glove for every chemical. Select according to substance, concentration, exposure and model-specific test data, then check fit and mechanical requirements.
What does EN ISO 374 Type B mean?
Type B requires at least Level 2 permeation performance against three listed test chemicals. The accompanying letters identify those chemicals. It does not indicate protection against every substance.
Are nitrile gloves resistant to all chemicals?
No. Nitrile performance varies by chemical and glove construction. Review compatibility data for the exact model, formulation and expected contact conditions.
Are oil-handling or liquid-handling gloves the same as chemical-resistant gloves?
No. Grip, liquid coverage and chemical resistance are separate properties. Hazardous-liquid contact requires chemical-specific evidence, even when a glove is marketed for oil handling.
Summary
Start with the chemical, concentration and exposure conditions. Use EN ISO 374 information and chemical-specific data to assess protection, then check coverage, grip and mechanical needs. Glove material, product naming and liquid-handling appearance alone do not establish suitability. Approve the supplied model only when its documentation matches the task.
