Heat-Resistant Gloves

Heat-Resistant Gloves — High-Temperature Work Gloves for Welding and Industrial Use

Heat-resistant gloves protect workers from burn injuries caused by contact with hot surfaces, molten metals, open flames, radiant heat, and hot liquids encountered in welding, foundry work, glass handling, furnace operations, bakery and food service, metal casting, and any industrial process involving high-temperature materials. OSHA 29 CFR 1910.138 requires appropriate hand protection when employees' hands are exposed to hazards including severe burns from heat, and ANSI/ISEA 105 provides standardized testing methods for heat and flame resistance that allow objective comparison of heat-resistant glove performance across manufacturers and models.

Welding gloves are the most widely used heat-resistant gloves in industrial settings, designed specifically for the combination of radiant heat, spattering molten metal (spatter), hot workpiece contact, and occasional direct flame exposure encountered in MIG, TIG, and stick welding operations. Leather construction — typically split cowhide, goatskin, or premium pigskin — provides the combination of heat resistance, spatter resistance, and tactile sensitivity needed for controlling welding equipment precisely while protecting against the thermal hazards. TIG welding gloves use thinner, more supple leather that preserves the fine motor control needed for TIG torch manipulation at the cost of some thermal mass; MIG and stick welding gloves use heavier leather construction for greater thermal protection against the higher spatter and heat outputs of these processes.

ANSI/ISEA 105 Thermal Contact Heat Resistance rating (formerly the Contact Heat designation) measures the threshold time in seconds at a given contact temperature at which a thermal transfer sensor reaches 10°C above ambient through the glove — a higher rating indicates better contact heat protection. Level 1 through Level 4 contact heat ratings correspond to performance at 100°C through 250°C contact temperatures. The ANSI 105 Convective Heat rating measures resistance to hot air convection (flameproof performance); the Radiant Heat rating measures resistance to infra-red radiant heat from furnaces and molten metal surfaces. Selecting gloves with ratings matched to the specific heat source type and temperature encountered in the application ensures appropriate protection without overspecifying unnecessarily thick or unwieldy gloves.

Aluminized gloves — gloves with a metallized foil outer layer over fiberglass or similar insulating fabric — provide superior radiant heat protection for foundry, furnace, and high-radiant-intensity environments where other glove constructions cannot provide adequate protection from intense radiant heat exposure without the foil's reflective layer. The aluminized surface reflects up to 95% of radiant heat rather than absorbing it, allowing the wearer to work near very high-temperature heat sources that would rapidly overheat a non-reflective glove. Aluminized gloves are typically used in continuous furnace charging, glass blowing, aluminum casting, and similar operations with sustained intense radiant heat exposure.

Our heat-resistant glove collection covers welding gloves in TIG, MIG, and stick configurations, oven and furnace gloves, aluminized high-temperature gloves, and cut/heat combination gloves for applications requiring both thermal and cut protection simultaneously. All gloves are rated with ANSI/ISEA 105 thermal performance levels to allow direct comparison and appropriate selection for specific temperature and heat exposure scenarios.

Frequently Asked Questions

What are heat-resistant gloves best suited for?

Align the glove with the hazard: puncture and chemical exposure, cut risks, heat, vibration, or general handling each call for a different material and construction.

What thickness or mil should I choose for heat-resistant gloves?

More demanding heat and chemical work suits thicker, more robust gloves, while light tasks suit thinner stock; thickness adds durability and protection at the cost of tactile feel.

Are heat-resistant gloves powder-free?

Following the food and medical standard, powder-free gloves avoid contamination and reduce skin irritation. Powdered options exist mainly for easier donning.

How do I pick the right size in heat-resistant gloves?

A palm measurement in inches gives you the size. A snug but not tight fit preserves dexterity and reduces hand fatigue during long use.

Are heat-resistant gloves food-safe?

Only gloves meeting FDA requirements qualify as food-contact-safe. Nitrile and vinyl are common choices for food handling because they are durable and powder-free.

What heat range do heat-resistant gloves handle?

Heat-resistant gloves are rated for specific contact and ambient temperature ranges. Check the rating against your exposure and contact time before use.

Do heat-resistant gloves protect against punctures?

Material and thickness set their puncture resistance. Nitrile resists punctures better than latex or vinyl at the same thickness, which matters around needles, wire, and sharp edges.

What is the difference between exam-grade and industrial gloves?

Barrier-integrity medical standards define exam-grade gloves, while industrial gloves emphasize thickness and durability for tougher mechanical work.

How should I store heat-resistant gloves?

Tuck them away in a cool, dry place out of direct sunlight. UV light and heat degrade glove materials over time, shortening shelf life and weakening the barrier.

Should heat-resistant gloves fit tight or loose?

Favor a snug, comfortable fit. A close fit improves control and reduces fatigue, while a little room aids airflow and easy removal; too tight tears at the seams and too loose snags.
