Absolute pollution exclusion is the standard pollution exclusion in Insurance Services Office, Inc. Commercial Liability Insurance (CGL) policies. (ISO) after 1986. This exception gets its name from the removal of the “sudden and random” exception from the standard 1973 CGL pollution exception. While it removes coverage for most pollution incidents that may occur in the course of an insured person’s business operations, coverage remains for some significant impacts, most notably certain incidental pollution losses (including hostile fire), product liability and completed operations, and some cases. - the premises are operated by contractors. Since the exclusion is not really “absolute”, a more appropriate nickname for it is “pollution exclusion in broad form”, and it is used in some IRMI publications.
