This self-paced online series covers the fundamentals of electrical installations in hazardous locations. Students who complete the series will be able to recognize areas that are likely to be classified and to select and apply wiring methods and electrical equipment in those areas. The series has been updated for the 2008 National Electrical Code. The EIHL Certificate Program serves professionals who need CEUs, want an efficient refresher, or need fundamental levels of guidance regarding hazardous locations. Complete all eight modules and earn .8 CEU.

These modules are included in the series:

• Classification Basics
• Identifying Materials & Equipment
• Protection Method Concepts
• Class I Applications
• Sealing in Class I Areas
• Zone Classification
• Class II Wiring Methods
• Class III Areas

Upon completion you should be able to:

• Explain the difference between area classifications, the protection methods, wiring methods and equipment used in each area, and the hazards associated with each classification.
• Explain the difference between explosionproof equipment and intrinsic energy methods and define key terms, including explosionproof, nonincendive and intrinsically safe, and explain the methods of creating dust-ignitionproof enclosures.
• Understand the hazards and concerns specific combustible fibers and flyings, the special hazards of metal dust and explain why stringent housekeeping requirements are important in Class III areas.
• Explain why stringent housekeeping requirements are important in Class III areas
• Know the methods of identifying appropriate electrical equipment for a given classified area based on the flammable or combustible materials that are present.
