• The clearance points where roads or right of ways enter and exit the required clearance zone
• If the one thousand-foot clearance zone needs adjusting to maintain the permissible clearance zone at all times, if the blast area moves as the job progresses
(5) Clearance zones.
Required clearance zones for:
Number of feet
Construction operations
1000 feet
Demolition operations
1000 feet
General industry operations, not subject to construction requirements

Vibration and damage control.

(1) Ground vibration - maximum limits.
Either Table 8-A or Table 8-B can be used to determine the maximum limits of ground vibration for any dwelling, public building, school church, commercial site, cofferdams, piers, underwater structures, or institutional building nearby the blasting site. The methods used for monitoring vibration and calculating frequency must be included in the blast plan.

1.00 in/sec (25.4 mm/sec)
5001 ft (1525 m) and beyond
0.75 in/sec (19 mm/sec)
1 Peak particle velocity must be measured in three mutually perpendicular directions and the maximum allowable limits must apply to each of these measurements.
(a) Frequency versus particle velocity graphics. In lieu of Table 8-A, a blasting operation has the option to use the graphs shown in Figure 8a or 8b to limit peak particle velocity based upon the frequency of the blast vibration. If either of the graphs in Figure 8a or 8b is used to limit vibration levels, the methods used for monitoring vibration and calculating frequency must be included in the blast plan.

(b) Scaled distance equations. Unless a blasting operation uses a seismograph to monitor a blast to assure compliance with Table 8-A or Figures 9a or 8b, the operation must comply with the scaled distance equations shown in Table 8-B.
Table 8-B
SCALED-DISTANCE EQUATIONS
Distance from Blasting Site
Scaled Distance Equation
0 to 300 ft (91.4 m)
W (lbs) = (d (ft)/50)2 or W (kg) = (d (m)/22.6)2
301 to 5000 ft (92 m to 1524 m)
W (lbs) = (d (ft)/55)2 or W (kg) = (d (m)/24.9)2
5001 ft (1524 m) and beyond
W (lbs) = (d (ft)/65) or W (kg) = (d (m)/29.4)2
Key:
W = The maximum weight of explosives in pounds (or kilograms) that can be detonated per delay interval of 8 milliseconds or greater.
d = The distance in feet (or meters) from the blast to the nearest dwelling, public building, school, church, commercial, or institutional building not owned, leased, or contracted by the blasting operation, or on property where the owner has not given a written waiver to the blasting operation.
Note:
To convert English Units of scaled distances (ft/lb2) to metric units (m/kg2) divide by a factor of 2.21.
(2) Air blast - Maximum limits. Air blast must not exceed the maximum limits listed in Table 8-C. Use Table 8-C to determine maximum air blast limits at any dwelling, public building, school, church, commercial, or institutional building not owned, leased, contracted, or on the property where the owner has not provided a written waiver to the blasting operation.
