Appendix G: Safety Around Explosive Devices
Concerns are expressed from time to time on the hazard of GPR products being used near blasting caps
and unexploded ordnance (UXO). Experience with blasting caps indicates that the power of Sensors &
Software Inc.’s GPR products are not sufficient to trigger blasting caps. Based on a conservative indepen-
dent testing house analysis, we recommend keeping the GPR transmitters at least 5 feet (2m) from blast-
ing cap leads as a precaution. Some customers do experimental trials with their particular blasting devices
to confirm with safety. We strongly recommend that GPR users routinely working with explosive devices
develop a systematic safety methodology in their work areas.
The UXO issue is more complex and standards on fuses do not exist for obvious reasons. To date, no
problems have been reported with any geophysical instrument used for UXO. Since proximity and vibration
are also critical for UXO, the best advice is to be cautious and understand the risks.
