Fifangaroan'ny acetylene sy oksizenina, raha miredareda ka mahatonga ny cylinder gasy manara-penitra hipoaka, miteraka fahafatesana sasany ao anatin'ny radius folo metatra. Ankoatra ny mety ho voan'ny potipoti-javatra cylinder, the immediate negative pressure and the blast wave from the explosion are powerful enough to be deadly.
I personally consider a distance of up to 20 meters from the explosion to be fatal. This scenario is exceedingly perilous.
