### sec.440ZB Blasting
A person must not conduct blasting if—
the airblast overpressure is more than 115dB Z Peak for 4 out of any 5 consecutive blasts; or
the airblast overpressure is more than 120dB Z Peak for any blast; or
the ground vibration is—
for vibrations of more than 35Hz—more than 25mm a second ground vibration, peak particle velocity; or
for vibrations of no more than 35Hz—more than 10mm a second ground vibration, peak particle velocity.
