SAFHAZ Safety and hazard data message (D19A)

This is the standard EDIFACT D19A spec, with 15 loops and 53 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.

Loading the spec…

The spec as an OpenAPI 3 schema with x-openedi-* extensions, for ediFabric Native, ediFabric Cloud and the EDI Spec Builder. Download OpenEDI (80 KB) Generate classes

The ediFabric .NET template, class TSSAFHAZ. It needs the common segments, composites and codes of EDIFACT D19A, one download for every transaction in the version. Download C# (1 KB) Common files (69 KB)

The intermediary model ediFabric Native loads with set_map. Native supports X12 today, and EDIFACT is coming. Download Native (1 KB)

Use the SAFHAZ spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read SAFHAZ files into TSSAFHAZ objects. See ediFabric .NET.

ediFabric Native

Native supports X12 today, and EDIFACT is coming. When it's available, map version D19A to this Native model with set_map to parse SAFHAZ files to JSON from Python, Java, C or C#. See ediFabric Native.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate SAFHAZ classes in Python, Java, Node.js, Go, Rust or C

The OpenEDI file describes each SAFHAZ as JSON. To work with SAFHAZ data as typed objects, generate classes from the OpenEDI file in your language; the root class is TSSAFHAZ. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats. Read more in Generate a class from OpenEDI.
