A frequent question I get here is whether or not NFPA 82 covers crematoriums under the definition of an Incinerator. Let's look at the definition of an Incinerator:
"3.3.7* Incinerator. Equipment predominantly designed for burning solid waste."
In the standard we do not define "solid waste". Therefore the definition of waste falls to Merriam-Websters Collegiate Dictionary.
"4 a : damaged, defective, or superfluous material produced by a manufacturing process: as (1) : material rejected during a textile manufacturing process and used usually for wiping away dirt and oil <cotton waste> (2) : scrap (3) : an unwanted by-product of a manufacturing process, chemical laboratory, or nuclear reactor <toxic waste> <hazardous waste> <nuclear waste>
b : refuse from places of human or animal habitation: as (1) : garbage, rubbish (2) : excrement—often used in plural (3) : sewage"
Most of the AHJ that I speak to do not classify Human or Animal remains as waste.
