An incident when SIP was used for special needs population.

The evacuation of this specific facility posed significant logistical issues. Buses needed to transport children were not on site, the process of loading them would be lengthy, and a location to accommodate the students would be needed. In addition, there was no present release occurring, but if there were, all of these functions would be performed downwind from the incident, thus potentially exposing handicapped children and the staff to the chemicals.

Therefore, it was determined that the most efficacious solution was to secure the HVAC equipment, close all windows and doors and shelter this facility in place. Even if there had been an ongoing release, this was the better choice because evacuation of this facility would have placed all involved individuals at much greater risk than sheltering in place.
