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?
