How do you choose heat resistant gloves?

Short answer: To choose heat resistant gloves, first identify the type of heat - contact (touching a hot surface), convective (hot air or flame), or radiant (heat radiating from a furnace or molten metal) - because each demands different materials. Then match the material (leather, aramid such as Kevlar, terrycloth, or aluminized) and the EN 407 rating to that heat type and the maximum temperature and exposure time. The right glove is rated for your dominant heat mode with enough cuff length to cover the wrist and forearm.

How to choose heat resistant gloves (2026)

Learning how to choose heat resistant gloves correctly matters because thermal protection is not a single property - a glove built for momentary contact heat can fail in seconds against sustained radiant heat. The European thermal standard, EN 407, scores gloves separately for contact, convective, and radiant heat (plus flame and molten-metal splash) precisely because they are different hazards. This guide is written for welders, foundry and kitchen workers, safety managers, and anyone who needs a glove matched to a real burn risk, starting from our heat-resistant gloves range.

The most common mistake is buying for material instead of heat type - assuming leather or Kevlar is universally heat-proof. Below we define the three heat modes, decode the EN 407 contact-heat scale and what its levels mean in temperature and time, compare the materials that target each heat type, and cover temperature ranges and cuff length so coverage extends past the wrist. For the broader hazard workflow, pair this with our guide on how to choose work gloves, and remember that heat gloves still need adequate grip and dexterity for the task.

Why this matters.
Thermal burns to the hands are a frequent and disabling injury in welding, foundry, kitchen, and maintenance work, and most come from a glove that did not match the heat type or the exposure time. OSHA's hand-protection rule, 29 CFR 1910.138, explicitly requires gloves selected for thermal burns and harmful temperatures based on a hazard assessment. Choosing by EN 407 heat type and rated temperature is what turns that duty into real protection rather than a false sense of security.

Part 1 - Choose heat resistant gloves by the type of heat

Before choosing any glove, identify how the heat reaches the hand, because each mode is tested and defended differently:

• Contact heat - the hand touches a hot surface, such as a pan, mold, or hot part. Protection depends on the insulation between skin and surface and how long contact lasts.
• Convective heat - hot air, steam, or flame transfers heat to the glove, common around ovens, open flame, and furnaces. Flame resistance and air-gap insulation matter most.
• Radiant heat - heat radiates from a very hot source without contact, as at a furnace mouth or molten-metal pour. Reflective (aluminized) surfaces are the primary defense.

Most jobs have one dominant mode plus a secondary one. Select for the worst-case mode first, then confirm the glove also covers the secondary exposure.

Part 2 - How EN 407 rates heat performance

The standard that decodes a heat glove is EN 407, which reports a six-digit code, each digit a performance level for a different thermal hazard, in this fixed order:

• Digit 1 - flammability (burning behavior), levels 1-4.
• Digit 2 - contact heat, levels 1-4.
• Digit 3 - convective heat, levels 1-4.
• Digit 4 - radiant heat, levels 1-4.
• Digit 5 - small splashes of molten metal, levels 1-4.
• Digit 6 - large quantities of molten metal, levels 1-4.

An X in any position means the glove was not tested for that hazard. Read the digit that matches your dominant heat type rather than the headline - a high contact-heat score says nothing about radiant protection.

Part 3 - Read the contact-heat levels in temperature and time

The contact-heat digit (position 2) ties a level to a contact temperature the glove can withstand for a defined threshold time, typically the time before the inside of the glove rises 10 degrees Celsius. The decode table below lists the EN 407 contact-heat levels with their reference temperatures. The practical reading rule: the level tells you the contact temperature the glove resists for the test threshold, not indefinitely - a higher surface temperature or longer hold than the test still burns. Match the level to your real surface temperature and contact duration, and browse rated options in our heat-resistant gloves collection.

Part 4 - Match the material to the heat type

Material is the lever that targets a specific heat mode:

• Leather - durable contact-heat and spark protection with good abrasion resistance; the workhorse for welding and general hot work, used in goatskin and cowhide builds.
• Aramid (Kevlar) - high thermal resistance without melting, excellent for contact and convective heat and cut resistance; common as a liner or knit shell.
• Terrycloth (cotton loop) - thick air-trapping loops for moderate contact heat in bakeries and kitchens; inexpensive but degrades when wet.
• Aluminized - reflective facing that bounces radiant heat, essential at furnaces and molten-metal operations.

For welding and spark-heavy work, a flame-resistant leather-and-Kevlar build like the MCR Safety Mustang HiDex goatskin Kevlar FR glove targets contact and convective heat with cut protection. Pure radiant exposure instead calls for an aluminized facing.

Part 5 - Temperature range, cuff length, and dexterity

Reading the rating is only half the job - confirm the manufacturer's stated maximum temperature and the exposure time it assumes, since a glove rated for brief 350-degree contact is not an oven mitt. Cuff length is just as important: hot work demands a gauntlet or extended cuff that covers the wrist and forearm, because that exposed gap is where most heat burns occur. A pig-split leather glove such as the MCR Safety Predator A5 pig split leather glove pairs leather heat and abrasion resistance with cut protection for general hot handling. As always, the most protective glove a worker will actually keep on wins - balance insulation against the dexterity the task needs, covered further in how to choose work gloves.

Part 6 - Heat plus cut, and what heat gloves are not

Heat hazards rarely arrive alone. Welding and foundry work often combine heat with sharp edges, so many heat gloves also carry an ANSI cut level or EN 388 cut rating - read both marks together. Two cautions: a heat glove is not a flame-entry or fire-fighting glove unless specifically certified for it, and it is not a chemical glove - hot solvent exposure needs the separate permeation logic in our chemical-resistant glove guide. Match heat gloves to thermal hazards, and reach into the broader hand protection range for combined or different hazards.

Part 7 - Worked example: how to choose heat resistant gloves for MIG welding

To make the process concrete, here is how to choose heat resistant gloves for a MIG welding station that exposes the hands to spatter (small molten-metal splash), radiant heat from the arc, hot workpieces (contact heat), and sharp metal edges. The goal is one glove that covers the dominant contact-and-convective heat with spark and cut protection.

1. Identify the heat types present. Per OSHA 1910.138, document the exposures: contact heat from hot parts, convective heat and spatter from the arc, some radiant heat, and cut risk from edges. The dominant modes are contact and convective heat with molten-metal spatter.
2. Set the EN 407 targets. Aim for a glove with a solid flammability digit and a contact-heat level of 3 or higher (350 C or more), plus convective-heat and small-splash ratings. Read the six-digit EN 407 code and check the digit for each mode you identified.
3. Choose the material. Leather with an aramid liner suits MIG welding - durable spark and contact-heat protection with cut resistance. The MCR Safety Mustang HiDex goatskin Kevlar FR glove is a flame-resistant leather-and-Kevlar example.
4. Confirm cuff length. MIG welding throws spatter up the wrist, so select a gauntlet or extended cuff that covers the wrist and lower forearm rather than a short knit cuff that leaves skin exposed.
5. Check the cut rating too. Because the station has sharp edges, read the glove's ANSI cut level or EN 388 cut mark and confirm it clears the handling hazard alongside the heat rating.
6. Trial, confirm grip, and standardize. Run a short trial to confirm the welder can hold the gun and feed wire with the glove on; then standardize the SKU and record the selection against the hazard assessment. Browse alternatives in the heat-resistant gloves collection.

The same heat-type-first method applies across hot work - from a terrycloth glove for a bakery to a pig-split leather glove like the MCR Safety Predator A5 pig split leather glove for general hot handling, to an aluminized facing for furnace radiant heat. For the full hazard workflow and the cut side of welding, see how to choose work gloves and how to read ANSI cut levels.

Frequently asked questions

How do you choose heat resistant gloves?

To choose heat resistant gloves, first identify the heat type - contact, convective, or radiant - then match the material and EN 407 rating to that mode and to your surface temperature and exposure time. Confirm enough cuff length to cover the wrist. Start from our heat-resistant gloves once the heat type is defined.

What is the difference between contact, convective, and radiant heat?

Contact heat comes from touching a hot surface, convective heat from hot air or flame, and radiant heat from a very hot source without contact. EN 407 rates each separately because they need different defenses - insulation for contact, flame resistance for convective, and reflective aluminized facing for radiant. Match the glove to your dominant mode.

What does EN 407 mean on gloves?

EN 407 is the European thermal-protection standard. It reports a six-digit code for flammability, contact heat, convective heat, radiant heat, small molten-metal splash, and large molten-metal splash, each rated 1-4, with X meaning not tested. Read the digit for your heat type rather than the overall impression.

What temperature can heat resistant gloves withstand?

It depends on the EN 407 contact-heat level and the glove's stated maximum: Level 1 resists up to about 100 C, Level 3 up to about 350 C, and Level 4 up to about 500 C, each for a defined threshold time rather than indefinitely. Always confirm the manufacturer's maximum temperature and assumed exposure time, shown in the decode table above.

How do I choose heat resistant gloves by material?

It depends on the heat type: leather for contact heat and sparks, aramid (Kevlar) for high contact and convective heat without melting, terrycloth for moderate kitchen contact heat, and aluminized facings for radiant heat. There is no single best material - choose heat resistant gloves by matching the material to the dominant heat mode.

Are Kevlar gloves heat resistant?

Yes - aramid fibers like Kevlar resist high temperatures without melting, which makes them excellent for contact and convective heat and as a liner in welding gloves. They also add cut resistance. For pure radiant heat, however, a reflective aluminized surface is more effective than aramid alone.

Do I need welding gloves or general heat gloves?

Welding gloves are heat gloves built for spark, spatter, and contact heat with extended gauntlet cuffs, usually in leather with an aramid liner. For non-welding hot handling, a shorter leather or terrycloth glove may suffice. Match the build to the heat type and spatter risk; the Mustang HiDex goatskin Kevlar FR glove is a welding-oriented example.

Why does cuff length matter on heat gloves?

Most hot-work burns happen at the gap between glove and sleeve, so a gauntlet or extended cuff that covers the wrist and forearm is essential where sparks, spatter, or radiant heat are present. A short knit cuff leaves skin exposed and is unsuitable for welding or furnace work.

Can heat resistant gloves protect against open flame?

Only if the EN 407 flammability digit and convective-heat rating are high enough, and even then a standard heat glove is not a fire-entry or fire-fighting glove unless specifically certified for it. Read the flammability and convective digits, and never treat a general heat glove as flame-entry equipment.

Do heat resistant gloves also resist cuts?

Many do, because welding and foundry work combine heat and sharp edges, so leather-and-Kevlar builds often carry a cut rating too. Read both marks - the EN 407 heat code and the ANSI cut level or EN 388 cut mark - to confirm the glove clears both hazards.

Does OSHA require heat resistant gloves?

OSHA requires hand protection wherever a hazard assessment shows a burn or harmful-temperature hazard. Under 29 CFR 1910.138, employers must select gloves for thermal burns and harmful temperatures based on the task's exposures.

How do I choose heat resistant gloves for foundry or molten metal work?

Molten-metal work needs high EN 407 ratings for radiant heat and molten-metal splash, so choose heat resistant gloves with aluminized facings to reflect radiant heat plus heavy leather or aramid backing. Read digits 4, 5, and 6 of the EN 407 code, and choose a long gauntlet for forearm coverage.

Are leather gloves enough for welding heat?

Leather handles contact heat, sparks, and abrasion well and is the traditional welding material, but for heavier arc heat an aramid (Kevlar) liner improves thermal and cut performance. Check the EN 407 contact and convective digits rather than assuming all leather welding gloves perform identically.

Can I use heat resistant gloves for hot chemicals?

No. Heat gloves resist temperature, not chemical permeation, so a hot solvent or acid needs a chemical glove selected by breakthrough time, not a heat glove. See our chemical-resistant glove guide for the permeation logic, and use a heat glove only for thermal hazards.

How long do heat resistant gloves last?

Replace heat gloves when the outer layer is charred, stiffened, cracked, or worn through, when stitching fails, or when terrycloth or leather is soaked, since moisture conducts heat and destroys insulation. Inspect before each shift, because a degraded heat glove can transfer heat far faster than its original rating suggests.

What heat glove do I need for kitchen or bakery work?

Moderate kitchen and bakery contact heat is usually well served by a terrycloth or leather glove at EN 407 contact-heat Level 2 (up to about 250 C), kept dry to preserve insulation. For higher industrial oven temperatures, step up to Level 3 or aramid. Match the level to your real surface temperature using the decode table.
