# Safety data sheet document profile

The **Safety data sheet** profile helps you index source-stated hazard handling information. It belongs to the technical quality family.

## Recognize the source

Recognizable hazard-information sections; do not certify safety or fill absent chemical properties.

Review the document itself before applying the profile. Similar labels, dates, parties, or amounts can appear in another document type with a different meaning. Use the source context to distinguish them.

## Expected fields

Core fields form the profile’s main structure. Recommended and optional fields add supported detail. None of these designations permits guessing a value that is absent or ambiguous.

| Field | Type | Inclusion | Meaning and extraction rule |
| --- | --- | --- | --- |
| Product identifier | text | Core | The source-stated product identifier for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| Supplier | text | Core | The source-stated supplier for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| Revision date | date | Core | The source-stated revision date for this document and its identified subject. Normalize an explicitly stated date only when unambiguous. Do not infer missing day, month, year or timezone. |
| Hazard statements | text | Core | The source-stated hazard statements for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| Safe handling excerpt | text | Core | The source-stated safe handling excerpt for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| First aid excerpt | text | Optional | The source-stated first aid excerpt for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| Storage excerpt | text | Optional | The source-stated storage excerpt for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |
| Disposal excerpt | text | Optional | The source-stated disposal excerpt for this document and its identified subject. Copy exact source spans for this one scalar field, preserving their order, ownership and qualifications. Ordered spans may continue across segments. Do not synthesize a summary or combine unrelated fields or repeated records; return unresolved when the scalar meaning is ambiguous. |

## Missing, ambiguous, and repeated values

Missing or ambiguous fields remain null with a reason. Null is not zero, false, an empty statement, or proof that a document-wide fact does not exist. Inspect unresolved states and their supporting passages before accepting the table.
This document type can contain repeated records such as **ingredients and hazard components**. The profile uses one row per document; do not compress repeated records into a scalar field or confuse a line value with a document-level total.
Additional supported fields can be considered when the extraction experience allows them. Review their definitions and types explicitly; changing a field’s meaning requires a new extraction preview.

## Review the result

Select evidence-backed cells and read the retained source. Text should preserve the relevant source spans and qualifications. Numbers and dates must be stated unambiguously and normalized safely; do not calculate unstated values or infer missing units, currency, scale, date parts, or time zones.

Verify the result against the captured document before acceptance. Source support does not independently establish perfect OCR, exhaustive field discovery, or correct domain interpretation.
