How to design airtight rooms for fumigation

Published: 29-Jun-2023

Do you design rooms that are subject to fumigation – the process of using a highly toxic gas to inactivate biological agents?

We recommend the white paper “Airtight solutions. A future-focused look at designing for fumigation” by Andrew Somerville of Hoare Lea and Shem Sacewicz of HOK Architects. It explains the process with common fumigants and highlights the need for airtightness. 

Andrew Somerville is a director and the science and research sector head at Hoare Lea, an engineering consultancy providing solutions to complex engineering and design challenges for buildings.

Shem Sacewicz is a senior associate and laboratory architect at HOK Architects with 20 years of experience of working on science projects in Europe and Asia.

Their white paper can help readers understand the fumigation process and the implication on room airtightness.

It says that retrofitting or consideration of sealability late in a design can be life-threatening and very expensive while “consideration of room airtightness requirements early in the design process will help achieve a safe and cost-effective result”.
