RESUMEN
Air quality in a cancer facility is integral to the success of patient treatment. The organization must be committed to providing a patient care environment free of physical and biological hazards that result from construction and demolition activities. This project intended to safely demolish a derelict building in Texas while minimizing air quality risks and impacts to nearby hospitals and a proximal cancer hospital. Two of the neighboring facilities were less than 18 feet (5.5 m) away from the demolition location. Adjacent facilities included inpatient and outpatient cancer treatment clinics, a large data center, a pediatric hospital complex, and a heart institute. Plans to minimize infection risks and dust for respective facilities were designed before implosion and remained in place until total debris removal. Risk assessments of nearby buildings were completed to determine the appropriate precautions and physical barriers needed. Culturable and non-culturable fungal air samples were collected during implosion to verify the management of outside contaminants. Additionally, continuous particulate and routine sampling for culturable and non-culturable fungi were performed for approximately 7 months after the project demolition. Air sampling results from 32 internal areas indicated that most areas remained at pre-implosion background levels. Areas that experienced elevated particle counts were cleaned and resampled, and baseline values returned to pre-implosion levels within 12 hr. Fungal air sampling results were acceptable based on predetermined infection control guidelines. The building was successfully demolished via implosion with no injuries and minimal damage to nearby facilities. The team learned that an integrated approach to project management that includes all stakeholders is essential to success. Contingency planning should account for all variables; no assumptions should be made. Staffing plans should be reviewed to ensure the sampling strategy developed can be implemented appropriately.
