Start the review with products liability.
For Industrial Process Furnace and Oven Manufacturing, the saved research highlights products liability, completed operations, employee injuries. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What types of industrial processes do the end customers use the equipment for — heat treating, curing, sintering, or other applications?
- Does the operation include field installation, commissioning, or ongoing service and maintenance at customer sites?
- What industries are the primary customers in — general manufacturing, aerospace, chemical, food processing, or other sectors?
- Are any products custom-engineered to client specifications, and does the manufacturer carry design responsibility?
- What is the geographic scope of sales — domestic only, or significant export activity?
- Has there been any prior products liability or completed-operations loss history?
- For Industrial Process Furnace and Oven Manufacturing, what should the underwriter know about products sold into high-hazard end-use industries such as aerospace, nuclear, chemical processing, or defense?
- For Industrial Process Furnace and Oven Manufacturing, what should the underwriter know about significant export sales, particularly to regions without robust product liability legal frameworks that may create coverage complexity?
