Q

When required to work in an area where explosive gases may accumulate, you should use hand tools which are __________.

🔍 Key Concepts

• Explosion-proof safety in hazardous atmospheres • Properties of ferrous vs. non‑ferrous metals when struck (sparking potential) • Why some tools are labeled “spark-resistant” or “non‑sparking”

💭 Think About

• Think about what could happen if a metal tool strikes another surface and produces a spark in an area with explosive gases. • Which type of metal is more likely to create sparks when it hits steel or rock: ferrous (iron-based) or non‑ferrous (like brass, bronze, aluminum)? • Consider what feature of the tool’s material matters most in a gas-filled space: strength, Coast Guard approval, or spark-producing tendency?

✅ Before You Answer

• Identify which option(s) describe tools that are less likely to create sparks. • Eliminate any choices that focus on government approval rather than physical safety characteristics relevant to sparking. • Check which metals are iron-based (ferrous) and which are not, and link that to the risk of ignition from impact.
