What is the pictogram for MP400 and MP500?

• A. May cause prolonged health effects
• B. Corrosive
• C. Environmental
• D. Flammable

Answer: (A)

MP400 and MP500 indicate a health hazard with potential long-term effects from exposure. The key idea is chronic toxicity: these pictograms alert you that repeated or prolonged contact with the product could cause lasting health problems, not immediate injuries. That’s different from a corrosive warning, which signals rapid damage to skin or metal; an environmental pictogram warns about harm to aquatic life; or a flammable pictogram signals ignition risk. Knowing that MP400/MP500 point to long‑term adverse health effects helps you understand the safety emphasis should be on minimizing cumulative exposure through proper PPE, ventilation, handling procedures, and hygiene practices to protect your health over time.
