OSHA 10-Hour Construction ReviewHealth Hazards in ConstructionMedium

A construction worker is working with a chemical that has a signal word 'Danger' on its label. What does the signal word 'Danger' primarily indicate according to the GHS (Globally Harmonized System)?

  1. AThe chemical is mildly irritating but not severely hazardous.
  2. BThe chemical presents a more severe hazard than indicated by 'Warning'.
  3. CThe chemical is only hazardous if ingested in large quantities.
  4. DThe chemical poses a less severe hazard than indicated by 'Warning'.
Show answer & explanation

Correct answer: B. The chemical presents a more severe hazard than indicated by 'Warning'.

Under the GHS, 'Danger' is used for more severe hazards, while 'Warning' is used for less severe hazards. Therefore, 'Danger' indicates a higher level of risk.

Why the other options are wrong

  • A. 'Warning' would typically indicate milder irritation.
  • C. The signal word indicates overall hazard severity, not just ingestion risk or quantity.
  • D. 'Danger' indicates a more severe hazard, not less severe.

GHS Signal Word 'Danger'

In the Globally Harmonized System (GHS), 'Danger' is a signal word used on chemical labels to indicate a more severe hazard level compared to the signal word 'Warning'.

  • Indicates a higher level of hazard severity.
  • Used for chemicals with significant risks.
  • One of two signal words in GHS (the other being 'Warning').

Memory trick: Danger means more danger, Warning is less!
