- What grains are processed, and does the facility handle any specialty or novel inputs?
- What dust collection, explosion suppression, and housekeeping protocols are in place, and when were systems last inspected?
- What is the total value of grain stored on-site at any given time?
- Does the facility hold bulk grain storage silos or grain elevator structures?
- What food safety and quality testing programs are in place, and is the facility subject to FDA FSMA requirements?
- For Flour Milling, what should the underwriter know about history of combustible dust incidents, fires, or explosions at the facility?
- For Flour Milling, what should the underwriter know about osha citations or regulatory actions related to grain handling or combustible dust standards?
- For Flour Milling, what should the underwriter know about deferred maintenance on dust collection systems, explosion suppression, or ventilation equipment?

Flour milling establishments receive raw grain — typically wheat, corn, rye, or similar crops — and process it through cleaning, conditioning, grinding, sifting, and blending operations to produce flour, meal, or prepared flour mixes. Operations typically involve large-scale industrial machinery, pneumatic grain conveying systems, bulk grain storage, and packaging lines serving commercial food manufacturers, bakeries, or wholesale distribution.
