A foundry shutdown combines conditions that normally exist separately. The furnace is stopped but still hot, refractory is being broken out by hand and with tools, hot components are being handled and replaced, and several trades work in the same area with a short window to finish. Hand protection has to cover contact heat, radiant heat, abrasive debris and mechanical work, usually across several stages of the same job.

What This Environment Does to People and Equipment
It is worth separating the two thermal hazards, because they demand different things from a glove. Contact heat transfers quickly at the point of touch, so the material and its thickness matter. Radiant heat arrives without contact and loads the surface continuously, which is what reflective surfaces are for. A person working inside a vessel can be exposed to both, and a glove that handles one well may be poor at the other.
The dominant condition is residual heat. Surfaces, structures and components remain hot long after the process stops, and radiant load from an open vessel or a hot shell reaches the hands and forearms even when nothing is being touched. Refractory removal adds abrasive dust and sharp debris, and the material being removed may contain constituents that the assessment needs to identify. Where casting continues during parts of the shutdown, molten metal exposure remains present in specific areas.
Gloves suffer quickly in these conditions. Leather stiffens and cracks, coatings abrade away, reflective surfaces lose their effectiveness, and seams fail at the points where the glove is gripped and pulled. Contamination with metal, scale or moisture changes how the surface behaves, and a glove that has received a splash or a heat soak may look serviceable while no longer performing as it was tested. That is why inspection criteria in this sector are written around condition rather than appearance.
The Hazards That Drive the Specification
Duration on a shutdown shift is longer than a routine production shift in most plants, and the work is more physical. That combination changes the requirement in a practical way: a glove that is tolerable for an hour of occasional hot work may be impossible for eight hours of demolition, and it will be removed at the point where the exposure is highest. The assessment should record the duration alongside the temperature.
- Contact heat from hot surfaces during demolition, cleaning and component handling.
- Radiant heat from open vessels, hot shells and furnace openings.
- Molten metal splash in the areas where metal is still being poured or transferred.
- Abrasion, cuts and impact from refractory, brickwork, tooling and heavy components.
- Refractory dust, which is an inhalation hazard as well as a skin and eye irritant.
- Moisture, which both conducts heat and creates the process hazard of water meeting molten metal.
- Duration: shutdown shifts are long and the work is repetitive, so the glove has to be wearable for hours rather than minutes.
The employer’s assessment sets the requirement, and the supplier documents what the glove is tested to. Because a shutdown moves through stages with different exposures, the assessment is most useful when it is written by stage and by area rather than once for the whole job.
Controls That Come Before the Equipment
Where a task still requires a hand near a hot surface, it is worth reviewing the tooling as well as the glove, because a longer handling tool or a different method often removes the contact rather than managing it.
That review belongs with the shutdown planning group, and it is the step that most often reduces the thermal requirement before the gloves are ordered.
Shutdown planning is where most of the hand exposure is removed. Cooling procedures and temperature monitoring define when work can start in each area; mechanised removal of refractory reduces the time hands spend in contact with hot and abrasive material; ventilation and dust control reduce the airborne exposure; and access and sequence planning keep trades out of each other’s work. Where the work involves water and hot material, the process controls that keep moisture away from metal belong in the plan rather than in a glove specification.
Administrative controls follow: permits, supervision, rotation, defined work limits related to temperature, and communication between the trades on site. Personal protective equipment is the last line of defence, and in a shutdown it is worth checking whether a task could be rearranged, or a longer cooling period provided, rather than absorbed by a heavier glove.
What the Equipment Has to Do Here
Dexterity matters more than it is usually given credit for in thermal work, because a glove that cannot grip a tool or seat a component will be removed for the difficult part of the task. Where the task genuinely requires fine control against heat, the better answer is usually to change the method so that the fine work happens away from the heat, and to keep the glove specified for the exposure that remains.
Gloves for this work have to do three things at once: resist the heat, avoid collecting material, and allow the worker to hold tools and components securely. That means long gauntlet cuffs that overlap the sleeve, seams positioned so that molten metal does not pool on them, and materials that do not melt, shrink or burn through quickly. Where radiant load dominates at a position, reflective surfaces are used; where abrasion dominates, leather and coated gloves perform better.
The interface with the rest of the set matters as much as the glove. The cuff has to work with the garment sleeve, the glove has to be repairable only in the ways the manufacturer permits, and the inner layers have to be specified rather than left to the wearer. The heat glove family, and how its performance is described, is set out in Shield Wings’ article on high temperature gloves, types, ratings and selection, which owns that topic.
Selection Criteria Specific to This Sector
Where a shut down follows the same pattern each year, the specification from the previous window is a useful starting point, provided it is reviewed against what actually happened rather than copied forward.
Where the work differs from last time, the review is the point at which the glove types and quantities are adjusted, rather than an exercise completed after the gloves have been ordered.
| Stage or task | Dominant exposure | Glove characteristics that follow | What to verify |
|---|---|---|---|
| Initial inspection after cool-down | Residual contact and radiant heat | Heat protective glove with a long cuff and documented contact heat performance | Temperature for that area and the documentation for the exposure claimed |
| Refractory removal and demolition | Abrasion, sharp debris, dust, impact | Durable leather or coated glove with mechanical resistance and a secure fit | Durability over the shift and the interface with arm protection |
| Handling hot components and tooling | Contact heat with a grip requirement | Contact heat performance with a grip pattern suited to the part | A trial with the actual component and temperature |
| Areas where metal is still being handled | Molten metal splash | Gloves specified for molten metal exposure with cuffs that shed material away from the arm | Documentation for the specific performance and the cuff arrangement |
| Radiant heat at an open vessel | Radiant load on the hands and forearms | Reflective glove or sleeve arrangement, with the reflective surface inspected and replaced | Condition of the reflective surface rather than the appearance of the glove |
| Cleaning and housekeeping during the window | Dust, debris and occasional hot material | Gloves matched to the task, with respiratory protection for the dust | That the glove and the respiratory protection are specified together |
Read across the table, the constant is that each stage has a different dominant exposure, and the practical arrangement is a small set of glove types issued against the stages of the job.
Typical Specification Failures in This Sector
One failure is organisational: the gloves are held in a store for the duration and issued at the start of each shift, but the sizes are limited and the crews are larger than usual because contractors are on site. The result is that part of the workforce wears a glove that does not fit, and a glove that does not fit is removed or worn loosely.
- One glove for the whole shutdown. Refractory removal and hot component handling are different requirements.
- Short cuffs. Material runs into a glove that ends at the wrist, and the wrist is where burns occur.
- Meltable layers underneath. Inner gloves or liners that melt against the skin make a burn worse.
- Gloves kept past contamination. Metal adhesion and stiffened areas are retirement triggers, not cosmetic marks.
- Stock planned for routine operations. A shutdown consumes gloves quickly, and running out mid-window means improvising.
- Equipment stored badly between shutdowns. Damp containers and sunlight degrade materials over the months between windows.
- Contractor provision assumed. Several employers in one area need one stated requirement, enforced at mobilisation.
Building the Full Set Rather Than Buying Pieces
It is also worth confirming what happens to gloves at the end of the window. Turnaround gloves are often returned to store in the condition they finished in, and a cleaning and inspection step before storage is what makes them usable at the next shutdown rather than a stock replacement.
The set for a foundry shutdown typically includes heat protective gloves for the hot stages, mechanical gloves for demolition and cleaning, arm protection that overlaps the cuff, and the body, face and footwear protection specified for the same tasks. Where molten metal is still being handled, the cuff arrangement and the interfaces with sleeves and leggings should be confirmed as part of the same specification.
Shield Wings manufactures hand protection at a Guangdong production base, including high temperature gloves and the wider families used in foundry work, and supports foundry, steel and industrial customers with material selection, cuff and construction options and the documentation each thermal claim requires. The glove range is listed in the hand protection category.
The planning that protects hands during a shutdown is done before the window opens: the stages identified, the exposure described for each, the gloves specified and stocked, and the crew briefed on which set applies where.

Evidence to Verify Before Approving Hand Protection for Foundry and Metal Casting Shutdowns
A supplier claim is not enough to approve Hand Protection for Foundry and Metal Casting Shutdowns. The purchasing file should connect the workplace hazard to the exact model, its supporting documents, and the configuration workers will actually receive.
| Verification item | What to request | Reason to stop approval |
|---|---|---|
| Hazard basis | Task, exposure, environment, and the site assessment that created the requirement | The product is being selected from a catalogue without a documented hazard basis |
| Exact product identity | Model, size range, material or component specification, and revision | The quotation and test document refer to different models or constructions |
| Model-specific evidence | Applicable standard, edition, test method, result, laboratory, and report date | Only a generic certificate, logo, or supplier declaration is available |
| System compatibility | Instructions showing how the item works with the rest of the PPE ensemble | Fit, coverage, accessories, or another PPE item creates a protection gap |
| Receipt and change control | Approved sample, SKU or lot link, inspection criteria, and notice of material changes | The delivered item cannot be tied back to the approved sample and evidence |
For U.S. programs, keep this evidence with the employer’s PPE assessment and training records. OSHA’s general PPE requirements make hazard assessment, suitable equipment, proper fit, and employee training separate obligations; a product certificate does not replace them. See 29 CFR 1910.132.
When to Reopen the Selection Decision
Approval should not be treated as permanent. Reassess Hand Protection for Foundry and Metal Casting Shutdowns when the work, product, evidence, or condition changes.
- The task or exposure changes: repeat the hazard assessment before carrying the old specification into a new process, energy level, temperature, chemical, or work location.
- The supplied construction changes: obtain revised model-specific evidence when fabric, coating, component, accessory, test standard, or manufacturing route changes.
- Fit or compatibility fails: stop issue when movement, coverage, visibility, communication, dexterity, or another PPE item is compromised.
- Damage or contamination appears: follow the manufacturer’s inspection and retirement instructions rather than relying on appearance alone.
- Records no longer match: quarantine stock when the label, SKU, batch, user instructions, and supporting report cannot be reconciled.
This review gate turns procurement into a controlled decision: hazard → model → evidence → fit trial → receipt inspection → periodic reassessment.
FAQs
How should a workplace select Hand Protection for Foundry and Metal Casting Shutdowns?
Start with the documented task and hazard assessment, then match the exact product model and configuration to the applicable requirements. Confirm fit and compatibility with the rest of the PPE system before issue.
What evidence should a buyer request for Hand Protection for Foundry and Metal Casting Shutdowns?
Request model-specific documentation that identifies the product, applicable standard and edition, test method, result, laboratory, and report date. The quotation, label, instructions, and test evidence should describe the same construction.
When should Hand Protection for Foundry and Metal Casting Shutdowns be reassessed?
Reassess it when the task, exposure, work environment, product construction, applicable requirement, or other PPE in the ensemble changes. Damage, contamination, poor fit, and missing records also trigger review.
Can a certificate alone approve Hand Protection for Foundry and Metal Casting Shutdowns?
No. A certificate may support one part of the decision, but the employer still needs a hazard-based selection, proper fit, worker training, compatible equipment, and inspection and retirement rules for the actual workplace.
