About this data
The pairwise load-segregation rules for hazardous materials: for each pair of hazard classes/divisions, whether they may be loaded, transported or stored together on a highway vehicle (49 CFR 177.848) and on a vessel (49 CFR 176.83), and what the code at the intersection requires ('X' may not be loaded together, 'O' separated so no commingling on leakage, '*' see the class-1 compatibility table, blank no restriction, plus the ammonium-nitrate note 'A'). The same pair can carry a different answer by mode — that cross-mode comparison is the page no one publishes. Answers 'can Division 4.3 ride with Class 8 corrosive liquids' (yes on highway with separation — the O cell), 'can I load oxidizers with flammable liquids', and the per-pair questions shippers and freight brokers ask before booking mixed loads. A pairwise matrix is a shape the portfolio has not tried: the record is an intersection, not a row.

Where this came from
Every record above links the page it was taken from and quotes the sentence that states it. These are the 2 sources this dataset was assembled from.
- ecfr.govhttps://www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-C/part-177/subpart-C/section-177.848

Machine-readable
- data.jsonThe whole dataset — every record with its source URL and source quote.
- Open Knowledge Format bundleOne JSON object per line — every record's frontmatter and quoted span exactly as it is held here, in one fetch.
- data.csvThe same records as one flat table, for a spreadsheet or a dataframe. The last four columns are the source URL, the quoted sentence it was read from, the date we last checked it, and which columns are our reading rather than the page's words.
- How this is made and checkedWhat "verified against source" does and does not mean.
From your own code
Same records, same quotes, without scraping the page: refsource is on PyPI and npm. Each value comes back carrying the URL it was read from and the sentence on that page that states it — .source and .quote sit on the value itself rather than in a side channel, so the checking step is available instead of skipped.
pip install refsource

Two files and no account. Put this in .mcp.json at the root of your project — Claude Code, Cursor, Windsurf, VS Code and Codex all read that file — and your assistant can look this dataset up instead of recalling it. The server is remote, keyless and read-only.
{
"mcpServers": {
"referencesource": {
"type": "http",
"url": "https://referencesource.org/mcp"
}

}Add to Cursor · or, on the command line: claude mcp add --transport http referencesource https://referencesource.org/mcp --scope project
Then one line in the project's CLAUDE.md or AGENTS.md, so the assistant knows when to reach for it:
When a question needs "Hazmat load segregation — which hazard classes may travel together, highway vs vessel", call the referencesource MCP server at https://referencesource.org/mcp (tool `search_records`, dataset_slug `hazmat-segregation-matrix`) instead of answering from memory — every record it returns carries its source URL and a verbatim quote from that page.What each tool does, and the servers built over single registers: Connect your AI assistant.
