dsh-hazchem-check — Hazardous chemical register and major hazard source identification check

<!-- topblock:v1 -->

What it is — Hazardous chemical register and major hazard source identification check. It returns a list of what is inconsistent, where, and what to fix.

Who it is for — safety and hazardous-chemicals managers; no command line required.

What you give it — the source material the check works on (a table, register or document); the original is never modified. Excel can be converted to JSON/YAML first, in chat if the platform supports it.

What it does not do — no compliance verdict, no liability finding, no replacement for the reviewer; differences only.

How to start — search "Safety Compliance Suite" in WorkBuddy / Coze (this check is one part of it; availability as listed); or:

dsh plugin --profile <name> add dsh-hazchem-check

<!-- /topblock:v1 -->



dsh-hazchem-check reads one hazardous-chemical register with its major-hazard-source identification record — the site header plus one row per substance — and checks that register's own completeness and arithmetic: that each substance carries a name and a hazard class, that the stored quantity parses as a number, that a threshold is recorded, that the “major hazard source” verdict agrees with how the stored quantity compares with the threshold the register itself states, that a stored substance records its safety data sheet number, that no CAS number is repeated, that the header declares the identification basis, and that no template placeholder survives in the name column.

You ask · What it answers

The register says “no”, but the stored quantity is above the threshold written beside it — is that caught? · Yes. HZ-003 compares the two numbers the register itself carries and reports the row when the verdict disagrees with them. It does not decide whether the unit really is a major hazard source.

A row has no threshold at all. Does the check say anything? · Yes. HZ-004 requires the threshold column to be filled on every row. It checks that a value is present, not that it is the right value for that substance — a 0 passes.

The chemical name is filled in but the hazard class is blank. · HZ-001 requires both on each row and reports the row missing either one. It does not judge whether the class is correct.

The quantity column reads 1,500 kg — will that still be read? · Yes. HZ-002 takes the numeric part; only a quantity it cannot parse is reported. Whether the figure is true, or taken at the design maximum, is not checked.

Which rows must carry a safety data sheet number? · HZ-006: every row that has a stored quantity. The rule checks that the number is filled in, not that the sheet is complete or belongs to that substance.

The same CAS number appears twice, in two warehouses. · HZ-007 reports a repeated CAS number, because it defeats both de-duplication and the quantity total. One substance split across warehouses is a legitimate shape: distinguish it in the storage-location column, or disable the rule. With no CAS column the rule reports that it could not run instead of passing silently.

Boundary: this plugin checks a 危险化学品台账与重大危险源辨识记录 for completeness and arithmetic — that

each chemical names itself and its hazard class, that the stored quantity parses, that a threshold is recorded,

that **the major-hazard-source verdict agrees with how the stored quantity compares to the threshold the register

states**, that a stored chemical records its safety data sheet number, that CAS numbers are not duplicated, that

the register declares its identification basis, and that no placeholder survives. It does not decide whether a

unit constitutes a major hazard source, whether it must be registered, whether a safety assessment is required, or

whether it is a major hidden danger.
