SDS accessibility requirements — what 'readily accessible during the shift' really means

It means an exposed employee can obtain the correct SDS for a chemical in their work area quickly and without barriers, on whatever shift they work. There's no fixed number of seconds, but the practical test is simple: if a worker were splashed right now, could they reach the sheet without a key, a password held by someone else, or a trip to a locked office? If the answer is no, the access requirement isn't met even though you technically 'have' the SDS. Posting a per-room access point workers can open on their own phone is a direct way to support that requirement.

Yes. OSHA permits electronic SDS access as long as there are no barriers to employee access and you have a reliable backup for foreseeable emergencies like power or internet outages. A laptop PDF folder that only the owner can open creates exactly that barrier; a no-login mobile page workers scan at the storage room is the kind of barrier-free access OSHA describes — provided you've planned an offline fallback and confirmed the setup for your own site. OSHA Scan hosts the PDFs and serves them from a QR poster, and the checklist above walks you through building the outage backup you still own.

Because access has to follow the worker, not the paperwork. A binder in the front office is out of reach for the night crew after the office locks, for the worker in the far warehouse aisle, and for the field crew on a jobsite. 'Readily accessible' is judged from where the exposed employee stands during their shift. Central storage is fine as a master copy, but each area where chemicals are used needs its own reachable access point.

By putting access where the chemicals are, not only at headquarters. Each truck, trailer, and remote site needs a way to reach the SDSs for the chemicals aboard or on hand. A per-location QR poster works well here: assign each chemical to its room or vehicle when you scan its label, then print a poster for that location so the crew opens the right list on their phone — no connection to the corporate binder required beyond loading the page.

No — and any tool claiming to auto-fetch every manufacturer SDS is overpromising. OSHA Scan reads a chemical's label from a photo to build the library entry, and you attach the manufacturer's SDS PDF, which is checked to look like a real SDS on upload. From there it makes the sheets readily accessible through QR room posters. Confirming that every chemical actually has its correct, current sheet on file is still a job for a competent person.
