Apply GHS-compliant labeling to secondary/diluted cleaning-chemical containers under OSHA HazCom

Steps

1. Determine whether the container qualifies for the OSHA 1910.1200(f)(8) 'immediate use' exception — a portable container filled and used entirely by the same employee within the same work shift is exempt from workplace labeling
2. For any diluted/decanted container that will be stored, transferred to another employee, or used beyond the immediate shift, apply a workplace label including the product identifier and general information on hazards (words, pictures, symbols, or a combination)
3. Use manufacturer-provided secondary labels where available, since many janitorial chemical suppliers print GHS-aligned secondary-container labels matching the concentrate's SDS
4. Ensure diluted product labels reflect the hazard of the diluted-use solution being carried, not just the concentrate, where the two differ materially
5. Train staff never to use unlabeled spray bottles and to relabel immediately if a label becomes illegible or detached
6. Periodically audit chemical closets and cleaning carts for unlabeled or mislabeled secondary containers
