Historical Version s – view previous versions of standard. This guide explains common hazards that often are overlooked.
It provides an overview of the standards and documents produced by ASTM Committee G04 and other knowledgable sources as well as their g1288. It does not highlight standard test methods that support the use of these practices. Table 2 provides a list of standards published by ASTM and other organizations.
ASTM G / GM – 15 Standard Guide for Control of Hazards and Risks in Oxygen Enriched Systems
In general, they are not directly applicable to process reactors in which the deliberate reaction of materials with oxygen is sought, as in burners, bleachers, or bubblers. The documents discussed here do not purport to contain all the information needed to design and operate an oxygen-enriched system safely. The control of oxygen hazards has not been reduced to handbook procedures, and the tactics for using oxygen are not simple.
Rather, they require the application of sound technical judgment and experience.
Oxygen users should obtain assistance from qualified technical personnel to design systems and operating practices for the safe use of oxygen in their specific applications. It is a starting point for those asking the question: The principal hazard is the prospect of ignition with resultant fire, explosion, or both. All fluid systems require design considerations, such as adequate strength, corrosion resistance, fatigue resistance, and pressure safety relief. xstm
In addition to these design considerations, one must also consider the ignition mechanisms that are specific to an oxygen-enriched system. This guide outlines these ignition mechanisms and the approach to reducing the risks.
Sources of information about the oxygen hazard and its control are listed and summarized.
Useful documentation from other resources and literature is also cited. This guide is an outgrowth of an earlier Committee G04 videotape adjunct entitled Oxygen Safety and a related paper by Koch 2 that focused on the recognized ignition source of adiabatic compression as one of the more significant but often overlooked causes of oxygen fires.
This guide recapitulates and updates material in the videotape and paper. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.
Combining values from the two systems may result in non-conformance with the standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory astn prior to use. For specific precautionary statements see Sections 8 and ASTM takes no position respecting the validity of any evaluation methods asserted in connection with any item mentioned in this guide.
