Fla. Admin. Code Ann. R. 69A-2.020 - Use; Loading of Explosives in Blast Holes
(1) All drill holes shall be sufficiently
large to admit freely the insertion of the cartridges of explosives.
(2) Tamping shall be done only with wood rods
without exposed metal parts. Non-sparking metal connectors may be used for
jointed poles. Plastic tamping poles may be used provided they have been
approved by the State Fire Marshal. Violent tamping shall be avoided.
(3) No holes shall be loaded except those to
be fired in the next round of blasting. Seismographic operations shall follow
this procedure wherever possible for maximum safety, but where practicality
will not permit, they are excepted from the provisions of this
subsection.
(4) Drilling shall not
be started until all remaining butts of old holes are examined with a wooden
stick for unexploded charges, and if any are found they shall be refired or
washed out by the blaster before work proceeds.
(5) No person shall be allowed to deepen
drill holes which have contained explosives.
(6) After loading for a blast is completed,
all excess blasting caps or electric blasting caps and other explosives shall
immediately be returned to their separate storage
magazines.
