DetNet safety philosophy is to design, manufacturer and provide control equipment, detonators and accessories to
the highest safety standards.
• Energy management in control equipment will be regulated by providing two separate circuits managing
test voltage and blast voltage, through software and hardware safety interlocks.
• BlastCards remain in possession of the accountable person and should only be used to authorize the blast
process at such a time as stipulated by the Mine after completion of the required Risk Assessment.
• All products must conform to local and international standards before it is sold for use.
• DetNet complies to ISO 9001, SANS 551:2009, CEN/TS 13763-27 which is acceptable to countries we
operate in; in countries not subscribing to the above marks, we advise users to engage with DetNet to
ensure that all equipment comply to local regulations.
Safety is ensured when the user supplements the product’s in-built safety systems through adequate training in the
safe use of the product:
• Induction training
• Refresher training
DetNet continuously upgrades software to make the products more user friendly and to ensure that users stay
abreast on latest developments, it is important that users get trained on the relevant changes before their
equipment is updated.
Inherent Safety
• CE4 Taggers are “Inherently Safe” because they cannot produce the necessary minimum required firing
voltage or encoded “Fire” command to initiate the electronic DigiShot
®
Plus 4G Detonator.
• In addition, the CE4 Tagger firmware does not contain the procedures or commands necessary to calibrate,
arm or fire the detonator.
