Sick Building Syndrome and Building-Related Illness Claims: Defining the Practical and Legal Issues
(The Construction Lawyer, October 1994, Volume 14, Number 4) Thomas F. Icard, Jr., and Wm. Cary Wright After more than a decade of litigation arising from civil claims based on exposure to airborne toxins,1 there is now widespread recognition that contamination of indoor air quality (IAQ) is a significant threat to public health. The Occupational Safety and Health Administration (OSHA) estimates that 30 percent of the nation’s 4.5 million existing commercial buildings have IAQ problems of varying degree.2 On April 5, 1994, OSHA published a seventy-page proposed IAQ rule in the Federal Register.3 While much of the media’s attention has focused on the environmental tobacco smoke (ETS) aspect of the rule, commentators have suggested that the “more dramatic impact of this sweeping proposal” may be the “overall regulation of indoor air quality”4 in nonindustrial buildings affecting more than seventy million workers.5 An indication of the economic significance of the problem is OSHAs $8.1 billion estimate of the cost of compliance with the IAQ aspects only (as distinguished from the ETS control requirements) of the proposed new rule.6 An indication of the current extent of public awareness of this issue is the fact that OSHA has received more public comment on this rule than that for any previous, proposed new rule in OSHA’s twenty-three-year history. Definition of the Problem There are two primary sources of IAQ-related problems: Microbial Contamination-those that are naturally occurring as a result of bacterial and fungal growth. This is often associated with excessive moisture within the building envelope. Typically, this problem is the result of improper drying in during the construction process, faulty roof or curtain wall construction, improper design or a lack of proper cleaning and maintenance
