Secondary Containers Need Clear Identification

Understand the hazard

Focus: Workplace labeling.

A spray bottle, scoop container, or small jug can separate a chemical from its original label. On a plating line, that can turn an ordinary handling task into an incompatible addition or accidental exposure. Our workplace labeling system must let workers connect the container to the right hazard information. A handwritten nickname is not enough.

Use the controls

Use the approved container and label before leaving a chemical for others or for later use. Keep the label readable and protect it from splash damage. If a limited immediate-use exception applies, follow its actual conditions; do not turn that exception into a general practice for the whole shift. Never use beverage containers for process chemicals.

Stop, report, and verify

An unlabeled container is an uncertainty to control, not a puzzle to solve by smelling it. Keep it in a safe designated location and contact the lead for identification and disposition. Do not pour it back into a tank or combine it with waste. Replace damaged labels through the approved system before the container returns to use.

Discuss with the team

A clear liquid is left in an unmarked squeeze bottle beside a rinse tank.

Question: What is the safe next step?
Answer guidance: Control access and have the container identified through the approved process; do not use or smell it.

Question: Can an unknown liquid be returned to a familiar tank?
Answer guidance: No. Its identity and disposition must be resolved first.

Prepare, practice, and follow up

Leader preparation: Bring the current instruction for workplace labeling, the relevant site checklist, and clean demonstration materials. Confirm the assigned lead and local stop-work response before presenting.

Activity: Review a sample workplace label and show how to find its matching safety data sheet.

Follow-up: Observe the next applicable task and verify this practice: review a sample workplace label and show how to find its matching safety data sheet. Record any gap, responsible person, and completion check before repeating the task.
