🔍 Key Concepts

• Ignition sources in engine rooms and fuel handling spaces • The purpose and design of explosion-proof equipment • Common causes of sparks around electrical systems and fuel vapors

💭 Think About

• Which option is specifically designed to prevent ignition in hazardous locations? • Among the choices, which ones can easily create exposed sparks or arcs near fuel vapors? • Think about what happens when fuel vapors contact unprotected electrical components versus equipment built for hazardous areas.

✅ Before You Answer

• Identify which device is intentionally built to minimize ignition risk in flammable atmospheres • Consider which items can produce open sparks or arcs during normal operation • Ask yourself which option would normally be required by safety regulations in spaces with fuel vapors
