Introduction
Liquefied petroleum gas (LPG), one of the most broadly used hydrocarbon fuels in the world, is also an important chemical raw material in the chemical process (Qian et al., 2021). Meanwhile, due to the flammable nature of LPG, fire and explosion accidents occur frequently once there is a leakage in its production, transition, storage, and utilization (Bariha et al., 2016). The explosion hazards caused by LPG have resulted in a large number of economic losses and casualties, such as the explosion accident caused by the leakage of an LPG tanker truck in Wenling, Zhejiang Province on June 13, 2020, which led to 20 deaths and 172 injuries (Lyu et al., 2022). Research on the explosion behaviors of LPG is valuable for developing methods and techniques to prevent corresponding explosion hazards.

Propane tanks do not explode. Period.
Propane does not explode. It may, under certain limited conditions, deflagrate or if contained detonate, but the flame front doesn't reach the speed for it to be termed an explosion.  We have words to accurately describe these things.  Explode is an incendiary, word with emotional strings attached to boot.
If you "smell gas" ventilate the space and turn off the fuel gas at its source.  Problem solved.

FWIW when I was a teenager, there was a resident in town who tried to re-light the pilot light in his propane or city gas water heater.  The resultant deflagration lifted his house above the foundation and the house turned slightly as it settled.  The man was taken to the local hospital and treated for his injuries.

While you may be technically correct, the distinction is somewhat irrelevant for most people as the resulting damage is indistinguishable from an actual explosion or detonation.
Also... well done calling an explosion an "incendiary word". I love a good pun.

Then I wonder what really happened here.  Your detailed articles are too technical for me to read and understand.  But if propane does not explode, then...what did?

There was no explosion per se.  I see too much unfounded fear being spread, and I am only trying to give the conversation some perspective.  If you use propane, you need to try really really hard to hurt yourself.  The odorant used, ethyl mercaptan, is very powerful and sickening when propane concentrations in air reach flammable levels.  If you smell the propane odor, open the doors and windows and go outside until it clears.  Shut the valve off at the propane tank.

The information in my reply #25 came from Art's link if you follow all the information there.

"RV gas detectors are intended to be replaced every 60 months.
Very few people realize this!"

My monitors were beeping a few months ago before I finally realized that there was not a leak but the 60 month mark had been reached.  Both my Propane and smoke detectors went off within a few days of each other.  There must be a built in timer.  They were impossible to ignore, but the older units don't necessarily have this feature.

During my 30 years as a firefighter, only a few things really scared me (where I thought I might die).  One of them was entering a LNG filled home to see a kid trying commit suicide by "flicking his Bic"!  My partner and I "tackled" him before the fuel/oxygen mixture reached the critical ratio.  I've seen the results of these explosions and they scare me.

Instead of checking the propane let's check our propane detectors,another safety precaution we can do is,if your not going to use
the propane for a few hours go outside and turn the manual valve off,does'nt take much,the propane did not cause the fire
something probably avoidable did.If your generator has shutdowns check them to make sure they actually shut the thing down,
it can be done.

I found a spot on our 90 G.V. at the rear of couch, gas line  and heat duct go through cabinet to H.W. heater . Spring in duct had started to wear into copper line . installed a piece of gasket material between them.
