Abstract— Explosives detonation could cause a partial or total destruction of equipment and installations, which in some cases derives in technical staff fatality. The present study aims to define blast wave parameters for spherical explosive in outdoor detonation. To achieve this purpose, a total of 30 blast wave tests were developed in samples of 1kg, 3kg and 5 kg of TNT; the experimental results were compared with standards and handbooks of explosion protection in order to evaluate the damage produced by blast wave effect in equipment, installations and technical professionals. The results reflect a range of safe-zones that varies from 7 m to 300 m according to explosives magnitude, furthermore the results also show the distance at which blast wave provoke lethal injuries. Finally, this research will be applied in further experimental tests related to the controlled demolition of building structural elements, to maximize safety ranges and minimize equipment damage, injuries and fatalities in these events.
