Where are gas cabinets & exhausted enclosures found?

Gas cabinets and exhausted enclosures are found in many of our client’s facilities, primarily in semiconductor fabrication and research laboratories. The appropriate amount of airflow is not always obvious to the designer.

What are the key codes for energy storage systems?

The key codes include NFPA 855, Standard for Installation of Stationary Energy Storage Systems 2020 edition, and the International Fire Code 2021 edition. The key product safety standard addressing ESS is UL9540, which includes large-scale fire testing to UL 9540a.

Are VMBs exhausted enclosures?

The ICC and NFPA codes more generally describe VMBs as exhausted enclosures. Ventilation rate selection is an important part of the deployment and use of gas cabinets and exhausted enclosures. The ventilation provides a measure of safety and deserves thoughtful attention by the design team.
