Are there limits on the number of precautionary statements on a secondary container label?

No. OSHA does not set a maximum number of precautionary statements. The label requirements depend on the workplace labeling method your employer uses.

What must appear on a workplace label?

For workplace containers, OSHA allows either of these labeling methods (subject to specific exceptions):

• • Use the shipped-container label elements, including the applicable precautionary statements for each hazard class and category.
  • Use the product identifier plus words, pictures, symbols, or a combination that gives general hazard information. The employer’s Hazard Communication Program must make the specific hazard information available to employees.

So, if you use the full label format, include the applicable precautionary statements unless an exception in OSHA’s standard applies. An alternative workplace label does not have to display every precautionary statement on the container, but it must meet OSHA’s workplace-labeling requirements and work with the hazard information available to employees.

How can precautionary statements be shortened?

When using the full label format, OSHA allows some flexibility while preserving the safety advice:

• • Combine or consolidate similar statements. This can reduce label text and improve readability, as long as the meaning and safety advice remain clear.
  • Use the most stringent similar precaution. When a chemical has several hazards and the precautionary statements overlap, include the most stringent statement. Precautionary statements for independent hazards still apply.
  • Make minor wording changes. A variation may improve communication if it does not weaken or compromise the safety advice. Use the wording consistently on the label and safety data sheet.
  • Omit a statement only when it is inappropriate. The chemical manufacturer, importer, or responsible party must be able to demonstrate that the statement is inappropriate for that specific substance or mixture.

Medical response statements

When multiple health hazards trigger medical-response statements, OSHA requires a prioritization approach. If the same response is triggered more than once, the label may show it once at the highest urgency, together with at least one applicable exposure route or symptom “If” statement. OSHA has additional rules for which “If” statements must remain, so review Appendix C before combining or omitting response wording.

See OSHA Appendix C, Allocation of Label Elements, especially sections C.2.4.6–C.2.4.10, and 29 CFR 1910.1200(f)(6) for the workplace-labeling options and requirements.
