Containment Capabilities Of A Class II, Type A2 BSC Using A Chemo Pad On The Worksurface

The Test Objective is to study the containment capabilities of the BSC when using a chemo plus prep mat on the worksurface. A NuAire model NU-425-500 Class II, Type A2 BSC was set to its nominal average velocity airflow of 70 fpm downflow and 105 fpm inflow, and  Personnel protection tests followed NSF/ANSI 49:2002 at nominal airflows using a chemo prep plus mat (10-3/8" x 16-1/2" size) on the worksurface in different configurations.
