Module 4: Safety & Emergency Procedures

Overview

This module covers all safety aspects of plasma cutting operations, including arc flash protection (PPE, barriers, safe distances), fume and thermal hazards specific to different metals, proper clothing and equipment selection, hot work permits and facility safety, and emergency response procedures. Students will demonstrate competency in PPE selection, donning, and emergency response scenarios.

Learning Objectives

  1. Identify and select appropriate PPE for arc flash protection
  2. Understand fume hazards and control measures for each metal type
  3. Explain the need for FR (flame-resistant) clothing and selection criteria
  4. Describe hot work permit procedures and facility controls
  5. Respond appropriately to emergency scenarios (arc flash, fire, fume inhalation)
  6. Implement engineering and administrative controls to minimize hazard exposure
