Chemical Labels: Identify It Before You Use It

Know the hazard

Team: General Small Business. Topic: Chemical Safety.

The color or smell of a liquid does not establish its identity. Two clear liquids can have very different hazards, and a familiar trade name may cover several formulations. Before using a product, confirm its identity and read the hazard and precaution information on its label.

Use the controls

Look for the product identifier, hazard statements, signal word, pictograms, and precautionary instructions as applicable. Connect that information to the planned task: could the product splash, ignite, react with another material, or create harmful airborne exposure? A label introduces the hazards; the safety data sheet and work instructions provide additional details.

Work within the safe plan

Keep original labels legible. For workplace containers, follow the employer's compliant labeling system. Do not treat an unmarked bottle as an acceptable shortcut, and never place chemicals in food or beverage containers. If a container cannot be reliably identified, stop using it and notify the designated person. Do not sniff, taste, mix, or trial-use it to determine what it is. Our rule is simple: the person who picks up the container next must have usable information, even if that person was not present when it was filled.

Discuss with the crew

A customer leaves an unlabeled spray bottle and asks a cleaning employee to use it on a countertop.

Question: Does the customer's assurance replace identification?
Answer guidance: No. The business must verify the product and assess safe use before an employee uses it.

Question: What should happen to the bottle?
Answer guidance: Keep it out of use and have the designated person resolve its identity and labeling without experimental testing.

Prepare, act, and follow up

Leader preparation: Bring a current labeled product container that can be handled safely without opening it.

Put it into practice: Have workers locate the identifier and a relevant precaution on the example product.

Supervisor follow-up: Inspect workplace bottles and correct the labeling process that allowed any unidentified container.
