🔍 Key Concepts

• 46 CFR Subchapter J electrical requirements for hazardous locations • How static electricity can be safely dissipated from moving machinery • The difference between conductive and non-conductive materials in preventing sparks

💭 Think About

• If a belt and pulleys can build up static charge, what must the system be able to do with that charge to reduce explosion risk? • Would leaving parts ungrounded make it easier or harder for static to safely discharge? • Think about whether you want electricity to stay on the belt/pulley, or have a controlled, low‑resistance path to the ship’s grounding system.

✅ Before You Answer

• Check which option provides a complete path for static charge to flow safely to ground. • Verify whether non-conductive materials help prevent or actually trap static electricity in this situation. • Confirm that the chosen option matches typical anti-static/ignition protection practices found in 46 CFR Subchapter J.
