A second series of fire tests utilizing the ASTM F-20 draft, Standard Guide for In Situ Burning of Oil Spills On Water: Fire-Resistant Containment Boom, as a guideline were conducted in a wave tank at the U.S. Coast Guard Fire and Safety Test Detachment in

Smoke Measurements Using a Helicopter Transported Sampling Package (NIST SP 995)

March 1, 2003
Author(s)
William D. Walton, Jay A. McElroy, W H. Twilley, R. R. Hiltabrand
A first generation smoke sampling package designed to be deployed on a helicopter winch cable has been developed. The package contains three sampling pumps which are operated via radio control from the helicopter. The pumps can be fitted with a variety of

Ignition of Weathered and Emulsified Oils (NIST SP 995)

February 28, 2003
Author(s)
Anthony Putorti, D D. Evans, E J. Tennyson
In situ burning of oil spills has been shown to be a rapid means of removing oil from the water surface. Although fresh oil is usually easily ignited, the ability to ignite weathered oils and water-in-oil emulsions is less certain. This paper presents
