🔍 Key Concepts

• Chemical burns and how they damage tissue • The difference between acids and alkalies (bases) • Common industrial or shipboard substances that can cause skin burns

💭 Think About

• Think about which types of substances can destroy or eat away at skin and tissue, not just irritate it. • Consider whether both strongly low pH (acidic) and strongly high pH (alkaline/basic) substances can burn skin. • Ask yourself if diesel oil typically causes the same immediate burning damage as strong cleaning chemicals or battery fluids.

✅ Before You Answer

• Identify which choices involve corrosive chemicals that can attack skin tissue. • Consider whether both extremes of pH (very low and very high) can cause burns. • Ask if diesel oil is mainly an irritant or a classic cause of true chemical burns.
