National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Products of the Oxidative Thermal Degradation of Elastomeric Noise Abatement Materials and Woods. Phase 2.

PB86160199

Publication Date	1982
Personal Author	Paciorek, K. L.; Kratzer, R. H.; Nakahara, J. H.; Harris, D. H.; Ahmed, S. R.
Page Count	168
Abstract	The primary objective of the program was to determine the toxic fume and fire hazards of elastomeric noise abatement materials with a limited effort expended on the evaluation of specific treatments applied to mine timbers. Under the conditions employed, the major toxic hazard for a dimethyl silicone rubber was formaldehyde; for both polyester and polyether urethanes and an acrylonitrile-butadiene-styrene resin, acrolein; for flame-retardant styrene-butadiene rubber compositions, hydrogen chloride; and for Pyresote-Firehold 10-Albi 144-treated timber, furfural. Of the materials studied, the flame-retardant styrene-butadiene rubbers presented the greatest toxic hazard. The generated data have been reduced to toxic load tabulations amenable to employment for potential hazard assessment.
