Directional airflow with minimum 12.5 Pa negative pressure differential and redundant exhaust fans with HEPA filtration.
Biometric access with airlock entry, clothing change areas, and shower-out facilities compliant with NIH/CDC requirements.
Liquid effluent decontamination system and gaseous decontamination capability for entire lab spaces.
Essential Engineering designed this 25,000 square foot Biosafety Level 3 (BSL-3) research laboratory for a government research institute working with hazardous airborne pathogens. The facility includes ABSL-3 animal holding areas and is designed to CDC/NIH BMBL 5th Edition standards.
Redundant exhaust fans with bag-in/bag-out HEPA filtration (99.99% on 0.3μm particles), redundant supply fans, and emergency power backup to maintain negative pressure during utility outages.
Dual-door autoclaves and dunk tanks for material transfer, with integrated interlocks to prevent simultaneous door opening. Separate clean and dirty corridors with pass-through chambers.
Audible and visual alarms for pressure differential loss, emergency shower/eyewash stations with drain sumps, and emergency power systems to maintain critical functions during outages.
