Which signal word is associated with Hazard Class I and chemicals that have severe corrosive properties but do not necessarily have very low oral LD50 values?

Which signal word is associated with Hazard Class I and chemicals that have severe corrosive properties but do not necessarily have very low oral LD50 values?

• A. DANGER
• B. WARNING
• C. CAUTION
• D. NOTICE

Answer: (A)

Signal words show how severe a hazard is and guide the level of precaution needed. Hazard Class I covers chemicals with severe corrosive properties. Even if their oral toxicity (LD50) isn’t extremely low, the potential for serious tissue damage from corrosivity makes this the highest hazard level. That’s why the strongest warning word—DANGER—is used. It signals the need for maximum protective measures and awareness of severe corrosive effects. The other words indicate progressively less severe hazards, while NOTICE isn’t used to convey a hazard level on pesticide labels. So, the signal word associated with these severe corrosive properties is DANGER.
