  • Description

    NFPA 86D provides requirements for safeguarding against fire and explosion hazards in Class D furnaces that operate at above ambient temperatures to over 5000 degrees F (2760 degrees C), and at pressures normally below atmospheric to 10(to the minus 8) torr (1.33 x 10(to the minus 6) Pa). It includes the many common safety requirements covered by NFPA 86D, such as for location, construction, heating system, safety equipment, testing, maintenance and fire protection.
