What is the detonation limit of diesel?
Thread Content
I would like to ask fellow sailors: what is the detonation limit of diesel? I checked online and there are many different statements: The first one is that the lower limit is 0.6% and the upper limit is 7.5%, as stated on page 62 of the **Comprehensive Book of Chemical Safety Techniques, 3rd edition**. I couldn’t find the book *Comprehensive Handbook of Chemical Safety Technology*, Third Edition ； The second type: detonation limit – 1.3～6% for gasoline, 0.7～5% for kerosene, 1.5～4.5% for light diesel; no data available for heavy diesel. One can consult the Material Safety Data Sheet (MSDS) online, where relevant hazard data is available in full. What exactly is the detonation limit of diesel? Is there an authoritative standard? I’d like to ask everyone for advice!
Explosion limit of diesel in air: 1.3%–6.0%
Diesel is a flammable liquid that falls under Category A fire hazards, with an explosion limit of 0.6% to 5.0%.
Is your answer based on any authoritative sources? It’s different from the reply on the third floor as well. I’m not trying to find faults; I just want to know the specific answer, preferably with relevant documents as evidence. Thank you!
Thank you for your reply! Is there any supporting evidence for this claim?
I think the reasoning isn’t sound; there are various grades of diesel with different viscosities, so I guess the explosion limit varies as well
Thank you very much for your question! Do you know if there are any national standards or specific reference books regarding the detonation limits of different grades of diesel? Thank you!
