The National Fire Protection Association's Standard 86 for Ovens and Furnaces will be examined during a two-day seminar scheduled for May 2 and 3 at the Hyatt Regency O'Hare in Rosemont, Ill. Produced by the Industrial Heating Equipment Association, the Safety Standards Seminar looks at NFPA 86 and how oven users and manufacturers are affected by the incorporation of NFPA 86C (governing industrial furnaces using a special processing atmosphere) and NFPA 86D (overseeing industrial furnaces using vacuum as an atmosphere) into one comprehensive standard.

“Attending the IHEA Safety Standards Seminar is always important to stay on top of the latest safety developments,” says Ray Ostrowski, seminar chairman. “Our speakers are 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 seminar will highlight changes in the newest version of NFPA 86, including:

  • Proof-of-closure and valve-proving
  • Leak testing of safety-shutoff valves (SSOVs) and allowable leak rates.
  • Oil system requirements.
  • Interposing relays.
  • Isolation valves.
  • Contaminant control/strainer and drip leg.
  • Venting to an approved location.
  • Vent limiters.
  • Temperature-limit controller requirement for indication and cautions on component failures.
  • Purging and safety ventilation.
  • Continuous-vapor concentration high limit controllers.
  • Storage systems for special atmospheres.
  • Inert purge gas requirements.

IHEA's Safety Standards and Codes Committee provided technical proposals for the 2003 edition and also for the 2006 edition, now under development.

“The focus of many of these proposals is to bring additional clarity to the specific requirements of the NFPA 86 Standard for the benefit of all those using the standard,” Ostrowski says.

Registration for the two-day seminar is $675 per person, and the registration fee includes a copy of NFPA 86. For a course outline and details, visit or call (513) 231-5613.
