Warning Notifications and Blasting Permits
It is not a requirement for a blasting firm to notify residents of blasting. Some municipalities who require blasting permits and notifications may post it on their local social media page, though. You may contact your local codes department to determine if a permit has been issued for your area.
Blasting firms are only required to warn personnel in the blasting area so they can retreat to a safe location. The blasting area is the area in which explosives loading and blasting operations are being conducted, including the blast site and the immediate adjacent area within the influence of flying rock, missiles, and concussion.
Unless prior approval has been given by the Commissioner, blasting operations shall only be conducted during daylight hours.
Damage and Filing a Complaint
The majority of the energy released from the blast goes to the intended work of fracturing the rock. A small portion of this energy goes into ground vibration or vibration in the air which might cause homes to rattle.
Only when a reportable accident occurs, the blaster in charge shall cease blasting operations immediately and shall be prohibited from conducting further blasting operations until such time as the Department's investigation is completed.
If your home or person is damaged from a blast, this would be a civil matter and would need to be determined by the insurance companies or a judge in a court of law. The State does not determine who is responsible for damages or personal injuries.
