1. “Enhanced Housekeeping Requirements in Egress Paths in Buildings with Polystyrene” ES&H Tier 1 Working Group Meeting Presentation MICHAEL KRETSCHMANN PE FIRE PROTECTION ENGINEERING February 8, 2011

2. JULY 2010 REPORT: ASSESSMENT OF BROOKHAVEN NATIONAL LABORATORY’S FIRE PROTECTION PROGRAM  Finding 201 O-FP-L 1-1: Egress paths in buildings with elevated fire risks (facilities that lack automatic sprinkler protection or have exposed polystyrene foam insulation* on the HVAC ducts) are not being maintained to assure access to exits are clear, unobstructed, and unencumbered (not to hinder or impede the action or performance of).

3. Polystyrene Polystyrene produces a highly intense fire and a thick black smoke. The intensity of a polystyrene fire has been proven to be able to outrun sprinkler protection in tests.
