The Industrial Heating Equipment Association (IHEA), Cincinnati, will hold its annual Safety Standards Seminar on May 11 and 12 at the Hyatt Regency O'Hare in Rosemont, Ill.

This year's seminar will review the newest edition of NFPA 86 Standard for Ovens and Furnaces, which became available in September 2003. It is a complete revision that incorporates NFPA 86C, the standard for industrial ovens and furnaces using a special processing atmosphere, and NFPA 86D, the standard for industrial ovens and furnaces using vacuum as an atmosphere, into one comprehensive standard.

A number of technical changes and clarifications also were made throughout the document, including:

  • Proof of closure/valve proving.
  • Leak testing SSOVs/leak rates.
  • Oil system requirements.
  • Interposing relays.
  • Isolation valves.
  • Contaminant control/strainer and drip leg.
  • Venting to an approved location and vent limiters.
  • Temperature limit controller requirement for indication and cautions on component failures.
  • Purging and safety ventilation.
  • Continuous vapor concentration high limit controller.

The entire document has been rearranged and renumbered. Manual of Style changes were incorporated throughout the document, which moved referenced publications to Chapter 2 and definitions to Chapter 3. Unenforceable language was removed from the standard.

"Attending the IHEA Safety Standards Seminar this year is of particular importance," notes seminar chairman Ray Ostrowski. "Our speakers were closely involved with all of the revisions that have been made to NFPA 86, and this is the best place for someone to learn first-hand of the updates to the newly published code."

The cost for the two-day event is $675, and attendees will receive a copy of the new NFPA 86 standard. For a course outline and seminar details, call (513) 231-5613 or visit www.ihea.org.
