NSF/ANSI 49 Annex I.1.9 states "The current lifespan of a [biological safety cabinet (BSC)] is approximately 15 years." However, your BSC's day-to-day operations will greatly impact its overall lifespan. Does the BSC run 24/7, daily, or simply as needed? What type of laboratory environment houses the unit? What procedures or protocols are used within the BSC? What cleaning procedure and materials are used? These all impact your cabinet's lifespan. Replacing parts, or the entire equipment itself, will quickly balloon your lab's operating costs and could even halt operations altogether.
