- What is the current workers comp experience modification factor, and what are the primary loss drivers in recent years?
- Are there any known environmental issues, regulatory notices, or prior remediation activity on the property?
- What waste streams are generated — slag, spent foundry sand, air emissions — and how are they managed and disposed of?
- Are any customers providing molds, patterns, or dies held on the premises?
- For Iron Foundries, what should the underwriter know about osha citation history, particularly for silica, heat stress, or crane operations?

Iron foundries melt pig iron and iron alloys in furnaces at extreme temperatures, then pour molten metal into sand or permanent molds to produce castings such as manhole covers, pipe fittings, engine blocks, and cookware. Operations involve continuous high-heat processes, heavy overhead crane and material handling equipment, significant noise and dust, and the production of waste byproducts including slag and foundry sand.
