Moisture or cooling leaks reaching molten alloy can cause severe injury and damage. The largest exposure depends on the actual route, materials, site, and equipment. Compare events included and property, employee, third-party and pollution terms rather than assume all benefits from a furnace incident.

Furnace fume, dust and slag warrant a separate pollution review. Describe materials, sites, history and treatment, disposal and transport duties. Check releases, cleanup and third-party claims included, prior conditions, notice and consent; routine emissions or slag duties, permit exceedances and fines are separate questions.

Check for covered internal furnace or transformer damage separately from refractory, wear, corrosion, process, or power conditions. Review repairs, affected stock and purchased income or extra expense, waiting periods and restoration terms. Continuous smelting and an outage alone do not insure every cost.

Off-spec composition can prompt claims. Identify alloy, use, cause, and any injury or damage to other property, then check products included, own-product, impaired-property and contract terms. Rejected alloy, remelting, impaired steel and a steelmaker shutdown alone do not insure every liability or rework cost.

Identify feed, alloy, process, actual dust, and gas exposure, worker status, and jurisdiction. Review applicable occupational-injury benefits and the covered loss. Ventilation or monitoring alone does not guarantee availability, favorable terms, benefits for every disease or pollution cleanup.

Underwriters weigh furnace size and power, safeguards, emissions controls, equipment values, payroll, and loss history. Each shapes pricing, subject to policy terms.
