Read the label.
Match it to the task.

S-04, C-04, O-04, supplier details, labels, sheets and records are fictional. The pictogram artwork is the existing unaltered OSHA public-domain artwork used in HC-001. Products are not real substances and no ingredient/CAS or validated exposure/compatibility data are supplied. The sheet is a teaching reference, not a regulatory SDS for an actual product.

The workplace-label exercise uses one supplied employer system: a matching product identifier and general hazard information, together with immediately available specific information under the program. It does not claim this is the only permitted method or that a pictogram alone suffices. The planned handoff falls outside the immediate-use scenario. Storage assignments and V-04/G-04 are supplied case assumptions, not real chemical/PPE approvals.

Only selected teaching extracts are supplied for O-04/C-04. SDS sections 7 and 10 guide their fictional compatibility placements. The release ends on HOLD; a completed practice review never provides a cleanup assignment or all-clear. Pictograms do not identify chemicals, capture every possible hazard, replace the full label/SDS, select PPE, or serve as transport labels.
