Scout's Toolbox Talks

Chemical labels often use symbols called GHS pictograms — part of the Globally Harmonized System — to quickly communicate the type of hazard a substance presents.

Why It Matters:

You may not always have time to read an entire label in the field. GHS pictograms give you an instant visual warning about what type of hazard you’re dealing with — flammable, toxic, corrosive, and more. Recognizing these icons can help you avoid serious harm.

Key Points:

• There are nine standard GHS pictograms used in construction and industrial settings.
• Common examples:
  • Flame = flammable materials
  • Skull and crossbones = acute toxicity
  • Corrosion = causes skin burns or eye damage
  • Gas cylinder = compressed gas under pressure
  • Health hazard (silhouette with starburst) = respiratory or organ damage
• Pictograms are set within red diamond borders — they’re not optional or decorative.
• One chemical might include multiple pictograms depending on its risks.
• Knowing the meaning of each symbol prepares you to take the right safety steps — like using ventilation or wearing gloves.

✅ If you see a red diamond pictogram, stop and assess the hazard before using the substance.

Ask the Crew:

• Can anyone name the pictograms on the labels we’re using today?
• What precautions should we take based on those symbols?
