SDSentry

What SDSentry does

SDSentry helps workplace teams find and review safety data sheets for chemicals and commercial products. Individual lookups can return the product, manufacturer, CAS number, EPA registration when applicable, SDS PDF, source type, printed revision date, signal word, GHS pictograms, and a confidence indication. When identification is uncertain, the result reports that instead of selecting a potentially incorrect sheet.

The service also supports OSHA Hazard Communication preparation. Its readiness tool describes the materials and processes a chemical-storing facility needs, including accessible current SDS records, GHS-compliant container labels, a written HazCom program, and documented employee training. It links to a free self-audit and explains the relevant 2024 update dates without adding penalty estimates or legal conclusions.

How it works

SDSentry is hosted remotely and exposes its functions through MCP. Product searches use SDSentry’s lookup service and its shared SDS library. Results distinguish manufacturer-hosted PDFs from third-party copies and include a public result page where available.

Requests can specify Spanish with language: "es". For a matching Spanish document, the response can provide the manufacturer’s own Spanish SDS rather than a machine translation. If that document has not been found or reviewed, the result states that status. Spanish label information uses official UN GHS wording for the applicable hazard codes.

Inventory searches accept up to 10 products per call. Items still being searched when the time limit is reached are marked for another request. Label links are included for up to five products in an inventory response when a manufacturer-hosted SDS is available.

Tools and capabilities

• find_safety_data_sheet looks up one workplace chemical or product and returns sheet metadata, hazard elements, confidence, source links, and secondary-container label resources.
• find_sds_for_inventory processes a list of up to 10 product names and returns one result row per item.
• search_sds searches by product or manufacturer and returns up to five read-only matches from the public search and shared library.
• check_hazcom_readiness explains facility readiness expectations and points to a no-signup self-audit.
• ghs_pictogram maps GHS01 through GHS09, or pictogram names, to meanings, listed hazard classes, OSHA requirement information, and a guide page.
• hazcom_2024_deadlines returns OSHA 2024 HazCom dates for substances and mixtures, including employer and supply-chain milestones and days remaining.

Found SDS records can include links to SDSentry’s free, no-signup GHS secondary-container label maker. The label is populated from the sheet when Section 1 and label elements have been confirmed; otherwise, hazard classes are selected manually.

Limitations and notes

SDSentry reports an item as not found when it cannot identify the product reliably. That behavior is important for inventory work because a plausible but incorrect SDS could misidentify workplace hazards. Third-party PDF copies are identified separately from manufacturer-hosted documents.

The inventory endpoint is batch-limited to 10 products, and its label links are limited to five qualifying products per call. OSHA State Plans may use different compliance dates from the federal schedule returned by the deadline tool. The available functions are read-only lookup and guidance operations; they do not replace a facility’s own HazCom program, training, or compliance review.
