Title Controlling vapours from open surface vessels.
Bibliographic information Dec. 1976, Vol.19, No.3-4, p.313-324. 2 ref.
Abstract Tests on canopy hood, "push-pull", rim, and central slot ventilation extraction systems are described. As access was an important consideration, the central slot proved to be the most practical. Air flow rates were varied to determine the most efficient volume required to control vapours under all operating conditions. For "undisturbed" locations (i.e. not subject to cross draughts, etc.) the results yield lower air volumes than given in a previous ACGIH pulication. Design criteria for the central slot extraction system are given.
