Industrial Special Risks Insurance
Also known as Industrial All Risks, ISR or IAR policies offer wider cover than property covers written on a fire and allied perils basis. While accidental damage cover is given in addition to the fire and allied perils, the main difference is probably the difference in the way cover is described. Under a fire and allied perils policy, the wording defines exactly what perils are covered. Under an IAR policy everything is covered other than the exclusions, defined in the wording.
