Side-by-side Fume Hood Testing: ASHRAE 110 Containment Report


The side-by-side fume hood testing compares two otherwise identical hoods – one conventional and one Berkeley hood – by measuring the escape of a tracer gas from each per the American Society of Heating Refrigeration and Air-conditioning Engineers (ASHRAE) 110-1995 Method (more below). Test results indicate that the Berkeley hood provides substantially better containment of potentially harmful fumes, and therefore greater operator safety, than a conventional fume hood. It outperformed the conventional hood in all tests.
