There are reports that tert-Butyl hydroperoxide has an NFPA 704 rating of 4-4-4, but it is not available in anything over 90 percent concentration, having 2-2-3. If you are ever in a place that needs such stuff, you are strongly urged to find a different job.
Oil much hotter flame and does NOT explode Propane is cleaner and is not considered toxic waste like an oil spillage Propane pockets thus it is a lot more dangerous Oil more moving parts (Burner motor ,filters etc)
