Question 1

How often should chemical fume hoods be inspected and certified?

Accepted Answer

We recommend that chemical fume hoods be inspected and certified annually at minimum. High-use or high-hazard environments may benefit from more frequent inspections—every six months or quarterly depending on your work demands. Our certification schedule makes sure your hoods maintain proper face velocity and containment performance throughout the year. We also do testing after any major modifications, relocations, or repairs to verify your equipment meets safety specifications before returning to service.

Question 2

What types of fume hoods can you service?

Accepted Answer

We service the many types of chemical fume hoods found in modern labs and industrial settings. Our technicians work with constant air volume (CAV) hoods, variable air volume (VAV) systems, auxiliary air hoods, and combination airflow technologies. We handle bench-top installations, walk-in hoods for large-scale processes, portable recirculating units, and double-faced demonstration hoods in educational settings. Our certification expertise covers equipment from all major manufacturers, so whether you have vertically rising sash systems, horizontal sliding configurations, or automatic sash closers, we deliver consistent service quality across your entire facility.

Question 3

What should I look for in a chemical fume hood service provider?

Accepted Answer

Look for a provider offering nationwide service with ANSI Z9.5 certification expertise and A2LA ISO 17025 accreditation. The right partner should have extensive experience serving your specific industry—whether pharmaceutical, research, chemical processing, or industrial manufacturing. They should deliver comprehensive testing with audit-ready documentation that satisfies regulatory requirements. Responsive communication, flexible scheduling that minimizes operational disruption, and consistent service quality across multiple locations are essential for facilities managing complex compliance programs. Allometrics delivers all of this with over five decades of laboratory service experience. Our certified technicians provide the testing, documentation, and support that quality assurance managers and operations directors depend on to maintain compliance and protect their teams.
