    Prevent dangerous furnace and boiler explosions!

    NFPA 8502: Standard for the Prevention of Furnace Explosions/Implosions in Multiple Burner Boilers provides vital safety requirements for boilers firing more than one burner and with a minimum fuel input of 12.5 million BTU/hr. It covers boilers that use pulverized coal, gas, and fuel -- and is newly revised to address single fuels as well as simultaneous firing of multiple fuels. Safety requirements such as interlocks and purging are intended to prevent implosions and explosions in the combustion system. (PDF, approx. 90 pp., 1999; 1995 edition also available)

An internet connection is not needed to fill in and save the forms once they are downloaded to your device.

    NFPA eForms can be used with many PDF applications. Functions of the specific PDF application will work on the forms. For example, most PDF applications include a signature feature, allowing you to use your finger, stylus, or mouse to sign a document. Note that it is recommended that the eForms be viewed and filled in through Adobe Acrobat Reader or higher, and not using the default reader of your device, for example, the iOS reader on iPhones.
