Electrical Safety for Chemical Engineers
 |  |  |
|---|
Objective: Know the electrical hazards relevant to chemical plants and lab projects (shock, arc flash, ignition of flammable atmospheres), the protections used (grounding, GFCI, fusing, lockout/tagout, hazardous-area equipment), and complete a safety review of your course project. Estimated time: 1-2 hours, due two class periods after assignment. This assignment is required before your project demonstration.
Chemical engineers sign off on equipment in plants where a spark can ignite a vapor cloud and where maintenance electrocutions are a leading cause of fatalities. Study the Electrical Safety lesson from Data-Driven Engineering, then complete the activity below.
Learn with AI
Apply to Your Project: Safety Review
Complete a safety review of your actual project hardware. Use the AI to generate the checklist, but walk the hardware yourself:
Walk through every item on your hardware, mark pass/fail, and fix at least the failures that involve current, heat, or liquids. The AI writes the checklist; you are the safety engineer who inspects and signs.
What to Turn In
Add a section (about 1 page) to your project notebook and submit it as a PDF. Answer these questions:
- Include the completed 10-item checklist with pass/fail marks, your fixes for failures, and your signature line as the reviewing engineer.
- What are the maximum voltage and current present anywhere in your project, and what protects the user from each?
- In one paragraph: your project moves from the lab bench to a Class I Division 2 area of a plant - name three things that must change and why.
- One safety claim from the AI that you double-checked against the lesson or a standard, and the result.
