How to Prevent Construction Dust in Occupied Spaces: Barriers and Protocols

Part 2 of a two-part series. Covers the protocols, barrier systems, and compliance frameworks that prevent construction dust from reaching occupied spaces. Includes traditional containment failure analysis (plastic sheeting and drywall), a head-to-head barrier comparison table, ICRA 2.0 classification matrix, CDC/Joint Commission requirements, NFPA 241 fire separation standards, negative air pressure system specs, anteroom decontamination procedures, continuous monitoring, and barrier selection guidance.
What Happens When Construction Dust Escapes the Work Zone in Occupied Spaces

Covers the health, legal, and financial consequences when construction dust escapes containment in occupied facilities. Includes sick building syndrome symptoms, silica/cancer/COPD risks, Aspergillus outbreaks in hospitals, OSHA penalty data, insurance pollution exclusions, data center hardware cascade failures, commercial tenant lease exposure, and Bay Area regulatory pressures.
