The NFPA 704 rating for propane is 2 for health (blue), 4 for flammability (red), and 0 for reactivity (yellow). This indicates that propane poses a high flammability risk, being easily ignitable, but it has low toxicity and is stable under typical conditions. The rating system helps emergency responders quickly assess the hazards associated with propane during incidents.
The NFPA 704 symbol for acetylene is a blue diamond with a white flame symbol on top, a red health hazard rating of 4 (extreme), a blue flammability rating of 4 (extreme), and a yellow reactivity rating of 0 (stable).
Cyclohexane does not have a specific NFPA diamond classification since it is not considered a hazardous material under the NFPA 704 standard.
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.
A 16 oz propane tank can typically last for about 1 to 2 hours, depending on the BTU rating of the device that it is fueling. This can vary based on the intensity of use and the specific appliance being used with the tank.
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)

In the NFPA 704 labeling system, a rating of 4 in any quadrant indicates a high level of hazard. Specifically, it signifies that the material is extremely flammable, poses a significant health risk, or is highly reactive and can explode under certain conditions. This rating alerts responders to the need for extreme caution and specialized handling procedures.
The first guide is from 1960.

The NFPA 704 diamond is a ring of smaller diamonds that are blue, red, yellow and white. A number or symbol in each section indicates the relative danger.

The NFPA 704 fire diamond rating for ethanol is 3-1-0. When handling ethanol, safety precautions should include wearing appropriate personal protective equipment such as gloves and goggles, working in a well-ventilated area to prevent inhalation of vapors, and storing it in a cool, dry place away from sources of ignition. Additionally, it is important to have proper fire extinguishing equipment nearby in case of a fire.
