What is the significance of the label’s signal words (e.g., CAUTION, WARNING, DANGER)?

• A. They indicate hazard level and guide required PPE and safety precautions.
• B. They are decorative and have no safety meaning.
• C. They indicate the color of the pesticide.
• D. They determine the cost of the product.

Answer: (A)

Signal words on pesticide labels show how dangerous the product is to people and what safety actions are needed. A lower-worded warning means relatively lower acute hazard, so basic protection is typically required. A higher-level warning signals more danger and stricter protective measures. The strongest term indicates the greatest hazard and calls for the most protective gear and precautions. The exact PPE and handling steps are specified on the label, but the word itself quickly communicates the level of risk and how serious the precautions must be. So, the best answer is that these words indicate hazard level and guide required PPE and safety precautions.
