Length: 2 days
CEU Credits: 1.4
Course Hours: 8:00 a.m.–4:00 p.m.

Description:

This course provides a detailed, systematic approach to specifying and implementing instrumentation in hazardous locations. Related standards from National Fire Protection Association (NFPA), National Electrical Manufacturers Association (NEMA), International Electrotechnical Commission (IEC), American Petroleum Institute (API), and ISA are discussed.

You will be able to:

• Use procedures for electrical area classification and basic principles of protection
• Interpret appropriate industry standards including those for NFPA, NEMA, IEC, API, and ISA
• Develop classification drawings using National Electrical Code and other national and international standards
• Apply explosion-proof seals and enclosures
• Specify intrinsically safe and non-incendive systems
• Apply dust safety principles and procedures
• Design purged and pressurized systems for instrument enclosures and control rooms
• Specify lightning protection for hazardous locations
• Assess the danger from spills of flammable liquids
• Select the appropriate protective techniques for different hazards and combinations of hazards
• Select the proper NEMA/IEC enclosures for different location classifications

You will cover:

• Introduction: Definitions | Safety Considerations | Principles of Ignition | Flammable Properties of Gases and Liquids
• Hazardous Area Classification: National Electrical Code | NFPA Standards | Classification Factors | Material Properties
• Dust Classification: Flammable Properties | Explosive Severity | Ignition Sensitivity | ISA Standards
• Enclosure Classification: NEMA | IEC
• Explosion-Proof Enclosures: Types | Installation Requirements
• Intrinsic Safety: Design/Construction Principles | ISA Standards | Implementation Considerations
• Non-Incendive Systems: Design and Implementation Considerations | ISA Standards
• Purging and Pressurization: Types X, Y, Z | Indications and Alarms | NFPA Standards
• Grounding Considerations: Electrical Grounding | Static Electricity | Lightning Protection
• Class II Division Classification: Standards | Dust Explosions | Combustible Dust | Flammable Properties | Temperature
• Class III Division Classification: Standards | Fibers/Flyings | Temperature Requirement | Classification Steps
• Zone Classification for Dusts: Standards | Dust Definition Zone | Class/Group Designation | Zone Designation | Zones vs. Divisions | Temperature Requirements
• Protection Techniques Standards: NFPA Standards | NEMA and UL Standards | ISA Standards

Classroom/Laboratory Exercises:

• Develop classification drawings
• Evaluate intrinsic safety systems using entity concept and circuit characteristics
• Analyze protective techniques for specified applications

Pre-Requisite:

• A hand-held/scientific calculator should be brought to class.

Includes ISA Standards:

• ANSI/ISARP12.06.01-2003 - Recommended Practice for Wiring Methods for Hazardous (Classified) Locations Instrumentation Part 1: Intrinsic Safety
• ANSI/ISATR12.24.01-1998 - (IEC 60079-10 Mod) - Recommended Practice for Classification of Locations for Electrical Installations Classified as Class I, Zone 0, Zone 1, or Zone 2
• ANSI/ISA12.01.01-2009 - Definitions and Information Pertaining to Electrical Equipment in Hazardous (Classified) Locations
• ANSI/ISA12.12.01-2007 - Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations, and selected draft reports.
