In-Depth Survey Report: Evaluation of Ventilation and Filtration System for LMDS and DPRC

摘要

Researchers from the National Institute for Occupational Safety and Health (NOSH) conducted an evaluation of the Ventition/Filtration System (VfS) developed for the United States Postal Service (USPS) mail processing equipment--the Loose Mail ditribution System (LMDS) and Dual Pass Rough Cull (DPRC). The VFS was developed and installed by a private contractor hired by the USPS to reduce the potential for employee exposure to harmful substances that could be contained in mail pieces processed by the equipment. NIOSH was asked to assist the USPS in evaluating controls for this and other processing equipment after the 2001 terrorist attacks that used the mail as a delivery system for anthrax.
