If you’ve ever poured a chemical out of its original drum or jug into a smaller bottle for use on the shop floor, you’ve created what OSHA calls a secondary container. Anytime a hazardous chemical moves from its original, manufacturer-labeled packaging into another container, whether that’s a spray bottle, a small jug, a beaker, or a mixing tank, that new container becomes subject to its own labeling requirement. You’ll run into this constantly in manufacturing, custodial work, labs, auto shops, and anywhere chemicals get decanted, diluted, or repackaged for daily use. The one exception is the “immediate use” carve-out: if the same employee who transfers the chemical uses it up entirely within that same work shift, and no one else touches it, you’re off the hook. The moment a container sits overnight, gets passed to another worker, or is used across shifts, a label becomes mandatory.

Employer Obligations Under OSHA HazCom

This isn’t just good practice, it’s a legal obligation under OSHA’s Hazard Communication Standard, found at 29 CFR 1910.1200. Under paragraph (f)(6), employers are responsible for making sure every workplace container of a hazardous chemical is labeled, tagged, or marked, and that duty sits squarely with the employer once the chemical leaves its original packaging. This is a separate obligation from the labeling duty that falls on manufacturers and distributors under (f)(1) through (f)(5), which governs the labels that ship with the original product. OSHA inspectors check for this regularly, and missing secondary labels are one of the more common citations issued under the Hazard Communication standard. You can read the full text directly on OSHA’s website, or the codified version on the eCFR website. It is worth noting that in 2023 alone, OSHA inspectors issued 315 citiations about Secondary Container Labeling.

Making a Compliant Label from Scratch

So what actually has to be on the label? OSHA gives employers two lawful routes. The first, under 1910.1200(f)(6)(i), is to simply replicate the full shipped-container label, meaning the product identifier, signal word, hazard statements, and pictograms, minus the manufacturer’s name and address. The second, and far more common, route is the simplified workplace label under 1910.1200(f)(6)(ii), which only requires a product identifier that matches the SDS, plus “words, pictures, symbols, or combination thereof” that give employees at least general information about the chemical’s hazards. To build one by hand:

• Start by referencing the chemical’s current Safety Data Sheet.

• Copy the exact product name from Section 1 to the label.

• Look at Section 2 for the hazard classification and pull the relevant pictogram, signal word (Danger or Warning), and the hazard statements - text like “Flammable liquid” or “Causes skin irritation.”

• Print or draw the signal words, pictograms and hazard statememts clearly on the label.

• Attach the label to the container in a spot that won’t get worn off by handling.

• Check to make sure the wording still matches what’s in the SDS binder or system employees can access, since the label is only half the story under HazCom.

How sdsLite Makes it Effortless

Doing this by hand for every chemical, every container, every time gets tedious fast, and that’s exactly where sdsLite comes in. Every chemical in your sdsLite SDS library comes with a Secondary Container Label ready to download, built automatically from the same data already sitting in Section 1 and Section 2 of that chemical’s SDS. There’s no retyping product names, no hunting for the right pictogram, and no risk of a hand-copied label drifting out of sync with the actual SDS on file. You pick the chemical, download the label, print it, and stick it on the container, all pulled from source data that’s already accurate and already audit ready.
