Hazardous Shipping Description
TITAN XL 1000 is made from TITAN 1000 or TITAN
1000 G bulk emulsion matrix.Refer to the TITAN 10M
Technical Information Sheet for Hazardous Shipping
4- Electronic Detonator Description information.
*Based on the capability of different densities (1.00 to 1.25),final cup density of 1.00 g/cc will be applied for shot 2.
This gives an average density of 1.138 g/cc shown in the chart on page 5.

Peak Particle Velocity and Scaled Distance
Let:
PPV= Peak Particle Velocity(in/sec)
K and m =Site Specific constants defining initial energy and
decay
Ds=Scaled Distance(ft./Ibs 0.5)
D= Distance to subject structure(ft)
Maximum charge per delay(Ibs)
Given:
D=2008'
Maximum charge= 1517.25 Ibs
K= 160
m =-1.6
Scaled Distance:
Ds= D/(./WMAX)"0.5
Ds=2008/(,/1517.25)^0.5
Ds=51.551
Peak Particle Velocity
PPV= K(Ds)Am
PPV= 160(55.551)^-1.6
PPV=0.291 in/sec
