Abstract
A flame suppression cabinet for printed circuit boards includes intumescent material that expands at an elevated temperature to block ventilation openings in a top panel. Fire suppression plates are positioned between adjacent ones of a plurality of printed circuit boards positioned vertically on a shelf rack in side-by-side spaced-apart parallel relationship to prevent fire from spreading between the circuit boards.
