What is the purpose of a signal word on a label?

• A. To indicate the severity of the hazard
• B. To identify the chemical name only
• C. To provide emergency contact details only
• D. To show the price of the chemical

Answer: (A)

Signal words tell you how serious the risk is and how urgently you should act. They’re part of the labeling system that uses words like Danger and Warning to indicate hazard severity, so you can prioritize protective measures and handling procedures. This helps you decide what PPE or precautions are needed and how carefully to work with the substance. It’s not about naming the chemical, giving contact details, or showing price.
