ASTM G145 is the ASTM standard titled Standard Guide for Studying Fire Incidents in Oxygen Systems. It provides a structured framework for examining fire events that occur in oxygen-related equipment and service environments, helping users approach incident review with greater consistency and care. By focusing on how such fires are studied, the guide supports safer engineering decisions, clearer evaluations, and more reliable technical documentation when oxygen systems are involved.

Overview of ASTM G145

ASTM G145 is a technical guide intended to support the study of fire incidents associated with oxygen systems. The standard is centered on incident analysis rather than design rules, so it is commonly used to help organize observations, review contributing conditions, and improve understanding of how a fire may have developed. As an ASTM standard, it is useful for teams that need a repeatable approach to assessment, documentation, and follow-up in oxygen-service environments.

Common use cases of ASTM G145

This guide is commonly used when reviewing fire events involving oxygen systems, such as equipment, assemblies, or service conditions where oxygen is present. It may support internal investigations, engineering evaluations, and quality or safety reviews tied to oxygen-related hardware. ASTM G145 is also relevant when organizations need a consistent method for documenting incident details and comparing findings across similar cases in testing, maintenance, or product support workflows.

Benefits of using ASTM G145

Using ASTM G145 can help improve consistency in incident study and reduce uncertainty during post-event review. It supports more disciplined documentation, which can aid compliance efforts, procurement decisions, and technical communication between engineering and safety teams. The guide may also help organizations identify recurring patterns, strengthen risk reduction practices, and evaluate oxygen-system performance with a clearer focus on fire-related concerns.

• Structured review of oxygen-system fire incidents
• Consistent incident documentation
• Support for engineering and safety analysis
• Useful in investigation and quality workflows
