What precautions should be followed when using a chisel having a mushroomed head?

🔍 Key Concepts

• Hand tool safety principles when using impact tools like chisels and punches • Dangers of a mushroomed head on a chisel (flying chips, metal fragments) • Proper methods of maintaining and dressing a chisel before use

💭 Think About

• Think about what happens to the metal at the head of a chisel after repeated hammer blows and why that shape is dangerous. • Which option describes a method that will leave a smooth, controlled surface rather than creating more cracks or loose fragments? • Which choices might actually create additional flying chips or only partially address the hazard instead of fully correcting it?

✅ Before You Answer

• Identify which choice involves careful reshaping of the metal versus simply hitting it again. • Eliminate any option that suggests actions that could knock off chips in an uncontrolled way. • Confirm that the correct precaution should result in a uniform, safe striking surface on the chisel head before further use.
