​​​​RP-87 EBW Detonator​

P/N 167-9643​

The RP-87 explosive is contained in a 0.006" thick stainless steel case which is crimped onto the plastic head. It is for use where small size is important. The RP-87 is similar to the MK 71 detonator in geometry and output except it contains no primary explosive.

Caution: While EBW and EFI Initiators are inherently less susceptible to accidental detonation during handling and set-up than devices containing primary explosives, electrical and electronic firing systems are sensitive to transient electrical energies which could cause premature triggering or firing. The blasting area must be clear of personnel and equipment before the detonator leads are connected to any RISI Firing System. Only approved RISI Firing Systems should ever be used to initiate or detonate any explosive product manufactured and authorized for sale by RISI.
