Side-by-side Fume Hood Testing: Human-as-Mannequin Report


The HAM test compares two otherwise identical hoods – one conventional and one Berkeley hood – by measuring the actual escape of the tracer gas from each, while an operator performs an identical set of choreographed movements with the same objects within each hood. 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, and on average provided two and a half to three times better containment.
