When it comes to handling hazardous chemicals, not just any glove will do. That’s where EN 374 gloves come in. Designed specifically to protect against chemical exposure and microorganism exposure, these gloves are a staple in laboratories, healthcare, food processing and cleaning.
But what exactly makes a glove “EN 374-certified”? And how do you choose the right type for your work?
What Does EN 374 Mean?
EN 374 refers to a European Standard (EN) that ensures a glove offers reliable protection against chemical and biological hazards. It’s not just a stamp of approval, it’s a guarantee that the glove has undergone rigorous testing.
This certification isn’t optional for safety; it’s essential. If your workplace involves exposure to harsh substances, EN 374 gloves aren’t just useful, they’re legally required in many industries to ensure worker safety.
What Does the EN 374 Standard Cover?
EN 374 is broken into multiple sections, each focusing on a different type of protection. Here’s a quick overview:
- EN 374-1 Chemical Risk Definitions: Outlines the terminology and performance requirements. This is the foundation.
- EN 374-2 Penetration Resistance: Tests if chemicals or micro-organisms can pass through pinholes or seams.
- EN 16523-1 (Formerly EN374-3): Permeation Resistance: Measures how long a chemical takes to break through the glove material.
- EN 374-4 Chemical Degradation: Examines how a chemical affects the glove’s material over time.
- EN 374-5 Micro-Organism Protection: Covers resistance to bacteria, fungi and viruses.
These parts work together to give users peace of mind. Whether you’re cleaning with strong disinfectants or working in biotech, these gloves act as your first line of defence.
EN 374 Glove Types
Not all EN 374 gloves are the same. They’re divided into three performance levels, depending on how many chemicals they can resist and for how long.
| Type | Chemical Resistance | User Case |
| Type A | At least 6 chemicals for 30+ minutes | High-risk chemical handling |
| Type B | At least 3 chemicals for 30+ minutes | General industrial use |
| Type C | At least 1 chemical for 10 minutes | Low-exposure environments |
You will often see images on gloves showing what type it is, along with codes for specific tested chemicals.
What Are EN 374 Gloves Made From?
Choosing the right EN 374 gloves isn’t just about the certification. It’s also about the material. Each type of glove material responds differently to different chemicals.
Nitrile
- Best for: Oils, solvents and a wide range of chemicals
- Why choose it: Tough, puncture-resistant and latex-free
Latex
- Best for: Water-based chemicals and biological materials
- Why choose it: Excellent dexterity and comfort
PVC
- Best for: Cleaning agents and petroleum-based oils
- Why choose it: Economical and good grip in wet environments
Picking the wrong material can reduce protection and lead to glove failure, so always check chemical compatibility.
How to Choose the Right EN 374 Gloves
If you’re looking at a wall of glove boxes with different labels, don’t panic. Here’s how to pick the perfect pair:
Identify the Hazard
- Are you dealing with acids, oils or biohazards?
- Match glove type to substance
Consider Duration
- For long-term exposure, go with Type A
- Short tasks may only need Type C
Think About Fit and Dexterity
- Latex for fine motor skills
- Nitrile for strength and flexibility
Look at Certifications
- Confirm EN 374 marks are clearly visible
- Check for additional standards such as EN388 (mechanical)
How to Read an EN 374 Glove Label
Understanding how to read EN 374 glove labels can help you make informed decisions about the gloves you are buying.
- Beaker icon: Chemical protection
- Shield with micro-organisms: Biological hazard resistance
- Letter codes (A, B, C): Glove type
- Chemical codes (A-T): The substances it resists
| Chemical Code Letter | Chemical | Category |
| A | Methanol | Primary Alcohol |
| B | Acetone | Ketone |
| C | Acetonitrile | Nitrile Compound |
| D | Dischloromethane | Chlorinated Paraffin |
| E | Carbon Disulfide | Sulphur |
| F | Toluene | Aromatic Hydrocarbon |
| G | Diethylamine | Amine |
| H | Tetrahydrofuran | Heterocyclic and Ethereal |
| I | Ethyl Acetate | Ester |
| J | n-Heptane | Saturated Hydrocarbon |
| K | Sodium Hydroxide 40% | Inorganic Base |
| L | Sulfuric Acid 96% | Inorganic Mineral Acid |
| M | Nitric Acid 65% | Inorganic Mineral Acid |
| N | Acetic Acid 99% | Organic Acid |
| O | Ammonium Hydroxide 25% | Organic Base |
| P | Hydrogen Peroxide 30% | Peroxide |
| S | Hydrofluoric Acid 40% | Inorganic Mineral Acid |
| T | Formaldehyde 37% | Aldehyde |
Always double-check the specific chemical tested. Don’t assume all Type A gloves protect against every substance.
Tips to Maximise Glove Safety
Even the best EN 374 gloves won’t protect you if they’re used incorrectly. Here’s how to get the most out of them:
- Change gloves regularly, especially after exposure
- Never apply hand sanitiser over gloves, as it can degrade the material
- Use the right size, tight gloves can tear and loose gloves reduce dexterity
- Dispose of contaminated gloves properly, especially after contact with biohazards
Your Safety Starts with the Right Gloves
Whether you’re a lab technician, cleaner or healthcare worker, EN 374 gloves are non-negotiable when dealing with chemical or biological hazards. They offer peace of mind, and when you choose the right type, fit and material, they also offer comfort and confidence.
