805 KAR 4:165 - Use of nonelectric initiation systems
RELATES TO: KRS 351.330
NECESSITY, FUNCTION, AND CONFORMITY: KRS 351.330 requires that the Department for Natural Resources prescribe rules to ensure that the use of explosives be conducted in a manner so that the safety of persons or property is not threatened. This administrative regulation provides standards to prevent the misuse of nonelectric initiation systems.
Section 1.
(1) All nonelectric initiation systems and
components of these systems shall be used in accordance with their
manufacturers recommendations and instructions.
(2) All members of the blasting crew shall be
instructed in the safe use of the initiation system and its components. It
shall be the duty of the blaster in charge to provide adequate on-the-job
training and supervision in the safe use of such system.
(3) No tool shall be used to pry on any
component containing a detonator, nor shall any tool be used to open, close,
fasten, or clean out any connector containing a detonator of detonating
device.
(4) Components of any
initiating system shall be used as originally manufactured; no one shall
attempt to modify or alter any component of an initiation system. Components
which are defective, damaged, or incompatible shall not be used, but should be
returned to the manufacturer or properly destroyed.
(5) When using surface components which
detonate and throw shrapnel, such components shall be covered with adequate
amounts of earth of other materials to prevent cut-offs and misfires.
(6) All blasting operations shall cease
during the approach and progress of a thunderstorm, regardless of the type of
initiation system in use.
(7) All
detonators shall be completely embedded inside the primer cartridge, and
securely fastened in a manner to prevent excessive tension or bending of the
cord or tube.
(8) When and
explosive bulk truck or other vehicle is operated on a blast site, care shall
be taken to ensure that the vehicle is not driven over the tubing, connectors
of any surface delay component. Precautions shall be made to protect these
elements before the vehicle is operated on the blast site.
(9) When using a system with surface delays
or detonators, any row of holes near a highwall where there is a danger of
falling rocks shall be connected into the shot last.
(10) In multiple row blasts, the initiation
system shall not be connected from row to row until all drilling and loading
have been completed. In single row blasts, the components shall not be
connected from hole to hole until all drilling and loading are
completed.
