Your AI Regulatory & Chemical Safety Expert
Ask Rex anything about the chemicals your company works with — PPE, storage, first aid, safe handling — and get an answer in seconds, pulled directly from your own Safety Data Sheet library.
Rex is included with every CanadaSDS subscription. Upgrade to Rex Pro to have Rex write your compliance documents and analyze hazards across your entire inventory.
What becomes possible with Rex
Rex saves your team the hours normally spent digging through SDSs and writing compliance documentation by hand. Here's what that looks like in practice.
Get instant answers from your SDS library
What PPE does this product need? Where should it be stored? What's the first-aid response if someone is exposed? Ask Rex directly and skip the search. Instead of opening a 16-section document and scanning for the right line, your team asks a question in plain language and gets the answer — with the product and section it came from.
Identify substances of concern
Search for PFAS, carcinogens, or sensitizers across your entire inventory and see every product that contains them. Rex reads the ingredient and hazard data in every SDS, so a single question surfaces products that a name search would never catch.
Rank and compare hazards across your inventory
Find your most hazardous products at a glance, so you know where to prioritize ERP training and controls. Rex can compare hazard classes, signal words, and exposure risks across your whole library and rank what deserves attention first.
See your compliance risk in one question
Ask Rex to flag obsolete SDSs still sitting in your library and any documents overdue for review. What normally requires a manual audit of every document becomes a single question with an actionable list as the answer.
Build a storage matrix
Tell Rex to run a storage audit for a facility or closet, and it checks every product against known chemical incompatibilities to flag unsafe combinations before they become a problem. Export the matrix to Excel, Word, or PDF whenever you need it on paper.
Write compliance documents in minutes, not hours
Ask for a Safe Work Procedure for any product in your library and get a complete draft, ready to review and put to use — the kind of document that normally takes a trained EHS professional an hour or more to write from scratch.
Find a safer product before an incident forces the question
Rex can surface safer alternatives for any product of concern in your library, so you can reduce hazards in your workplace with confidence. Rex matches on how a product is actually used — not just its name — so the alternatives it suggests are ones your team can realistically switch to.
Rex comes with your subscription. Rex Pro does the heavy lifting.
Every CanadaSDS account includes Rex, ready to answer the everyday questions. Rex Pro takes on the bigger jobs above — storage matrices, hazard rankings, and compliance documents — across your entire library at once.
