Does apartment insurance cover carbon monoxide incidents?
Carbon monoxide injuries may be excluded under the pollution exclusion in standard liability policies. Pollution liability coverage is the most reliable way to cover CO-related claims.
Carbon monoxide (CO) poisoning in apartment buildings is a serious risk, particularly during heating season. The CDC reports approximately 420 unintentional CO poisoning deaths annually in the United States, and faulty furnaces, water heaters, and gas appliances in apartment units are a leading source. From an insurance perspective, the critical question is whether the general liability policy's pollution exclusion applies to CO claims.
The ISO Commercial General Liability policy (CG 00 01) defines pollutants broadly as 'any solid, liquid, gaseous, or thermal irritant or contaminant, including smoke, vapor, soot, fumes, acids, alkalis, chemicals, and waste.' Courts have split on whether CO qualifies as a pollutant under this definition. Some jurisdictions (including decisions in New York and Illinois) have found that the pollution exclusion applies to CO, barring coverage. Others have limited the exclusion to traditional environmental pollution and found coverage for CO incidents. The outcome is jurisdiction-dependent and unpredictable.
Given this uncertainty, apartment owners should not rely on the general liability policy to cover CO incidents. An environmental pollution liability policy that specifically includes CO as a covered pollutant provides definitive coverage. Additionally, apartment owners should comply with CO detector requirements, which vary by state. For example, California Health and Safety Code Section 17926.1 requires CO detectors in all dwelling units with fossil-fuel-burning appliances, and New York Executive Law Section 378-a imposes similar requirements. OSHA's general industry standard (29 CFR 1910.1000) sets permissible exposure limits for CO in the workplace, which applies to on-site maintenance staff.
