Acetylene is commonly used for welding in small-scale industries
due to the high temperature of the flame; however, it is
extremely flammable, and mixtures with air containing between
2.5 and 82% acetylene are explosive on ignition [1,2]. Accidental
or suicidal cases of death due to inhalation of acetylene and/or
involving trauma induced by acetylene explosion are occasionally
encountered in forensic science practice [1,3,4]. The risk of acetylene
inhalation or acetylene explosion for industrial workers is also
a problem from a health point of view [3–7].
