Identification of the shockwave effect onto Explosive Ordnance Disposal (EOD) personnel during controlled airblast of TNT charge

Abstract eng:
The aim of this study was to identify the effect of the shockwave emitted during explosion of the TNT charge onto Explosive Ordnance Disposal (EOD) Personnel. Within the work, the basic information about the air blast and its influence on the human body were discussed. The necessity of well fitted protective equipment application was highlighted. Detonations of the few different charge masses were performed. Pressure in the dummy ears and accelerations of its head were examined. The obtained records were compared with maximum allowable levels of those parameters taken from literature. It was noticed that even for small charges, which do not poses a threat for structures, the risk of body injury caused by the blast pressure cannot be neglected .
