Steel foundries are among the most hazardous industrial environments. Workers face intense radiant heat, molten metal splash, sparks, airborne contaminants, and heavy equipment hazards. To stay safe, foundry workers must rely on a complete PPE system that protects against thermal hazards, arc exposure, and molten metal splash. This checklist outlines the essential PPE categories every steel foundry safety program should include.
Aluminized Thermal Protection (Primary Heat Barrier)
In steel foundries, radiant heat and molten metal splash are the most serious hazards. Aluminized PPE is specifically designed to reflect radiant heat and protect against molten metal exposure.
Aluminized garments can protect workers from molten metal splash temperatures up to roughly 2,900°F and radiant heat exceeding 3,000°F depending on fabric design.
One example used in high-heat environments is the Carbon Armour H5 Aluminized Foundry Coat, designed with an aluminized OPF-carbon rip-stop blend for molten metal and radiant heat protection.
Typical aluminized PPE includes:
- Aluminized jackets or coats
- Aluminized aprons
- Aluminized pants or leggings
- High-heat hoods and head protection
These garments reflect radiant heat while preventing molten metal particles from sticking to the fabric surface.

Arc-Rated FR Base Layers
Underlayers are critical in high-heat environments. Foundry PPE systems often require arc-rated flame-resistant base layers that will not melt or ignite when exposed to heat or sparks.
FR base layers provide:
- Thermal protection under aluminized gear
- Moisture management for heat stress
- Secondary protection during flash events
Proper layering also improves comfort and helps reduce heat stress when wearing heavy protective equipment.
Recommended FR Base Layers:
· Carbon Armour FR AR Moisture-Wicking Long Sleeve Mock Turtleneck
· Carbon Armour FR AR Moisture-Wicking Base Layer Long Underwear
Molten Metal Resistant Gloves
Hand protection is essential when workers are handling molds, tools, or equipment near molten metal.
Foundry gloves should offer:
- Heat resistance
- Molten metal splash protection
- Cut and abrasion resistance
- Extended cuffs or gauntlets for forearm protection
These gloves protect workers from both radiant heat and accidental contact with hot surfaces.
Recommended Foundry Gloves
· Carbon Armour Silvers H5 Aluminized
· Cut Resistant Aluminized Thermal Gloves
· Aluminized Rayon 16 in. Gloves with Reinforced Thermal Leather Palm and Adjustable Cuff
High-Heat Head and Face Protection
Face and head protection is critical during pouring operations or furnace work.
Foundry head protection systems often include:
- Heat-resistant hard hats
- Aluminized hoods
- Face shields or goggles
- Neck protection for radiant heat
Recommended High Heat Face Protection
· NSA Aluminized High Heat Head Protection Kit
· H5 Aluminized Flip Front Hood Metalized Gold Polycarbonate Faceshield
Protective face shields and visors help shield workers from molten metal splash and flying debris during casting operations.
Respiratory Protection
Steel foundries can produce airborne hazards such as:
- Silica dust
- Metal fumes
- Combustion gases
- Sand particulate
Respiratory protection may include disposable respirators or supplied-air systems depending on the exposure level.
Recommended Respiratory Protection:
· Z-Link Radiant Heat Respirator Helmet
· Crystal 2.0 PAPR Welding Helmet - Optrel
· Bullard GVX Abrasive Blasting Respirator

Heat-Resistant Leg and Foot Protection
Molten metal and sparks can easily enter footwear if clothing is not properly layered.
Recommended lower-body protection includes:
- Aluminized leggings or spats
- Heat-resistant work pants
- Metatarsal protection
- Foundry-rated boots
Recommended Heat Resistant Products:
· 11 oz. Aluminized OPF Ripstop Leggings
· Aluminized Chaps 19 oz. OPF/Para-Aramid Blend, Leather Belt, Foot Flaps
· Carbon Armour Silvers H5 Aluminized Pants
Proper layering ensures molten metal cannot enter the boot opening during pouring operations.
Eye Protection
Eye protection should always be worn in foundry environments.
Typical eye protection includes:
- ANSI Z87+ safety glasses
- Heat-resistant goggles
- Face shields for pouring operations
Recommended Eye Protection:
· Defiant Safety Glasses with Adjustable Temples
· Face Shields with Ratcheting Headgear
· HexArmor - Safety Glasses - X1 TruShield®
These protect workers from sparks, debris, and radiant heat exposure.
PPE Inspection Checklist for Foundries
Before each shift, workers should inspect their PPE for damage.
Key inspection checks include:
✔ Check aluminized garments for tears or worn reflective surfaces
✔ Inspect FR clothing for contamination or holes
✔ Check gloves for burn damage or worn seams
✔ Ensure face shields are clear and undamaged
✔ Verify respirators and filters are functioning properly
Regular inspections ensure PPE continues to perform under extreme foundry conditions.
Protecting Workers in Extreme Heat Environments
Steel foundries expose workers to some of the most dangerous thermal hazards in industrial operations. The right PPE system from aluminized thermal barriers to arc-rated base layers helps protect against molten metal splash, radiant heat, and airborne hazards.
