This 5-hour course presents the methods for purging and pressurizing enclosures to prevent ignition of a flammable atmosphere. By these means, electrical equipment that is not otherwise acceptable for a flammable atmosphere may be utilized in accordance with Article 500 or Article 505 of NFPA 70.
The course materials are based entirely on the NFPA 496, Standard for Purged and Pressurized Enclosures for Electrical Equipment, 2008 Edition. It will be necessary for the student to obtain a copy of NFPA 496, 2008 Edition. This is a very useful resource and is recommended that all practicing electrical or project engineers involved in the specification, design, installation, and maintenance of purged and pressurized enclosures for electrical equipment should be familiar with and up to date with the rules provided in this standard.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
