Identifying Materials & Equipment
Continuing Education Units (CEU): 0.10
Expected Duration: 1 Hour
This self-paced online course covers materials that can result in a classified area and equipment that is suitable for those areas. The degree of hazard and the types of electrical equipment needed to reduce the hazard are dependent on the properties of the specific flammable, combustible, or ignitable materials.
Upon completion you should be able to:
- Determine the materials that can result in an area being classified
- Select equipment that is suitable for those areas
- Identify the methods and reasons for distinguishing between different types of materials
- Identify the reasons for grouping materials based on their characteristics
- Know the methods of identifying appropriate electrical equipment for a given classified area based on the flammable or combustible materials that are present
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- Areas are classified due to the presence or possible presence of flammable gases or vapors, flammable liquids, combustible dust, or ignitable fibers or flyings.
- The nature of the explosion or fire hazard and the types of electrical equipment needed to reduce the hazard depend on the properties of the specific materials present.
- Some materials are more hazardous than others or may involve different hazards than others.
- Therefore, equipment must be selected for compatibility with the specific materials present, including the Class, Division or Zone, and Group.
- To ensure compatibility, equipment must be properly identified and marked.
