What is NFPA 85? Why is it important? How does it work?

NFPA 85 is a standard developed by the National Fire Protection Association (NFPA) that provides guidelines for the safe operation of boilers, furnaces, and other fuel-burning equipment. The standard covers a wide range of topics related to the design, installation, operation, maintenance, and testing of these systems, with the goal of ensuring safe and reliable operation while minimizing the risk of fires and explosions. NFPA 85 is applied to units at or over 12,500,000 btu boilers.

NFPA 85 is important because it helps to protect people, property, and the environment from the hazards associated with fuel-burning equipment. By providing guidelines for the safe operation of boilers and furnaces, NFPA 85 helps to prevent fires and explosions that could result in property damage, injuries, or even fatalities.

The standard works by providing a set of requirements and recommendations for the design, installation, operation, and maintenance of fuel-burning equipment. These requirements and recommendations cover a wide range of topics, including:

  • Combustion control systems
  • Flame detection and monitoring
  • Fuel handling and storage
  • Boiler feedwater treatment
  • Pressure and temperature controls
  • Safety valves and relief devices
  • Testing and inspection procedures

NFPA 85 is enforced by local and national authorities having jurisdiction, such as building inspectors and fire marshals. Companies that operate fuel-burning equipment are typically required to comply with the standard in order to obtain permits and certifications. Noncompliance can result in fines, penalties, or even the shutdown of operations in some cases.
