In <i>Matcon Diamond, Inc. v. Penn National Ins. Co.,<\/i> No. 186 WDA 2002 (Pa. Super., Jan. 17, 2003), a policyholder was sued when its employee succumbed to carbon monoxide fumes while using a gas-powered tool in an enclosed workspace. The policyholder turned to its insurer for a defense, but the insurer denied coverage based on its pollution exclusion. The court agreed with the insurer, holding carbon monoxide constitutes a &quot;poisonous gas,&quot; falling within the policy&#39;s exclusion for injury caused by exposure to &quot;solid, liquid, gaseous, or thermal irritant or contaminant including smoke, vapor, soot, fumes, acid, alkalis, chemicals and waste.&quot; The court observed that the federal Clean Air Act and the Superfund Act designate carbon monoxide as a pollutant. According to the court, carbon monoxide is reasonably anticipated to cause death or physiological malfunction upon inhalation and, therefore, constitutes a pollutant or irritant excluded from coverage.<\/p><p>If you have any questions about <i>Matcon Diamond<\/i> or about any other insurance issue, please do not hesitate to contact any of the following attorneys in the Insurance Coverage Group at McCarter &amp; English, LLP:<\/p><table align=\"center\"><tr><td>Andrew T.
