Mr. Wilkes stated that the data sheets only list the chemicals contained in a given product, and tells nothing about the concentrations in the air other than what chemicals are likely to be present during a product use. In addition, he pointed out that MCPS does not know what chemicals are being used on the site on any given day or week, and that the air monitoring program is random. No criteria for air concentrations has been developed or accepted, so the evaluation of the air quality data by MCPS is purely subjective. Since the air monitoring program is not measuring the air concentrations of the majority of construction chemicals, there is no way of knowing if there are unacceptable exposures. Asbestos removal is never done during the school year because the risk of toxic exposure is too great.
Asbestos removal follows very strict safety standards.
Dr. Benz stressed communication, morale, safety, air quality and parking as some of the major concerns she is facing during construction. She requested, and was given, extra support such as additional security and building services personnel, and an on-site coordinator. This person took care of planning all field use, after-school and nighttime activities in coordination with the contractor. The school information and master calendar was communicated to the contractors months in advance. Strict guidelines were developed for behavior of construction personnel and students, and strictly enforced.
