Which term describes substances that destroy human tissue?

• A. Anesthetic substances
• B. Corrosive substances
• C. Carcinogenic substances
• D. Teratogenic substances

Answer: (B)

Substances that destroy human tissue are corrosives. They cause chemical burns and tissue necrosis by reacting with cells and proteins on contact, leading to rapid damage to skin, eyes, or mucous membranes. This property sets them apart from anesthetics, which blunt sensation; carcinogens, which raise cancer risk; and teratogens, which can cause birth defects. In practice, corrosives include strong acids, strong bases, and some oxidizers, with damage severity depending on concentration and exposure time. Safety focuses on preventing contact through proper PPE and engineering controls, and if contact occurs, immediate decontamination with plenty of water.
