Cleanroom Demolition Project

Interior demolition projects pose challenges of all kinds, some much more challenging than others. The challenge on one particular R. Baker & Son project was to perform extensive interior demolition in a space adjacent to multiple class-100 cleanrooms. The facility owners required that there could be no interruption to facility operation, which ran twenty-four hours a day, and that demolition activities would have no negative impact on the clean spaces.

To ensure that no dust or particulates would infiltrate the cleanrooms, R. Baker & Son’s team of demolition experts devised an ingenious vacuum airlock. A 35 ft. wide by 16 ft. high by 18-inch wide cavity was constructed from aluminum studs and drywall. The interior of the airlock was sealed with wall panels specially designed for clean rooms, and several ¾-inch holes were bored into both sides of the cavity to draw air in. Three HEPA exhaust fans were installed on the dirty side, drawing 1,500 CFM into the sealed cavity to create a vacuum. Differential pressure gauges installed on both sides of the void showed a constant negative pressure of a half inch, effectively preventing particulates from migrating from the work area to the clean spaces. The owner was fully satisfied with R. Baker & Son’s resourceful solution, and cleanrooms remained contaminant-free through the duration of the demolition project.
