Chemical Labeling & GHS Pictograms

Toolbox Talk:

Read the Signal Words and Precautionary Statements

June 27, 2025

Every chemical label includes important language beyond pictograms — specifically signal words and precautionary statements that spell out the level of hazard and required safety actions.

Why It Matters:

Labels are your first line of defense. Knowing the difference between “Danger” and “Warning” can tell you how quickly something can harm you — and how carefully it must be handled.

Key Points:

  • Signal Words:
    • “Danger” is used for more severe hazards.
    • “Warning” indicates less severe but still significant risks.
  • Precautionary Statements offer specific actions to reduce exposure:
    • Example: “Wear protective gloves. Avoid breathing fumes.”
    • These statements are tied directly to the type of hazard listed.
  • Labels often include First Aid instructions in case of exposure.
  • Always check both the label and the Safety Data Sheet (SDS) for full details before using a substance.
  • Don’t ignore familiar products — even basic cleaners can carry serious risks depending on concentration or use.

✅ Treat every label seriously, even if you’ve used the chemical before.

Ask the Crew:

  • Have you ever seen both “Danger” and “Warning” on jobsite labels?
  • What do today’s chemicals say under precautions? Are we following them?
