License holders: Please notify the Department of any changes in your employment or contact information.

Notice: there is an error on the 2022 Blaster’s License renewal notice. The note stating that the Continued Education Training should have been completed by 8/31/2020 is wrong. The correct requirement is 8 hours of Continued Education Training to be completed between 09/01/2019 through 08/31/2022.

Training and Certification for a Blasters' License

This program applies to individuals who are interested in initially securing a blaster's license for surface operations or for adding an additional classification to an existing surface license. A person may not detonate explosives or supervise blasting activities unless the person has obtained a PA Blaster’s License in the classification required for the work they are doing. Blaster’s licenses must be renewed every three years.

The Department’s Bureau of Mining Programs is responsible for blaster’s licensing and certification. We accomplish this in part by holding training and certification classes several times each year during which we relate Commonwealth regulations as it relates to current blasting technology and common techniques. This program applies to individuals who are interested in initially securing a blaster's license for surface operations or for adding an additional classification to an existing surface license.

The regulations regarding blaster’s licensing in Pennsylvania are found in Title 25 PA Code, Chapter 210.

In general, anyone who wishes to obtain a PA Blaster’s License must:

  • Be 21 years of age or older.
  • Have a current ATF clearance as an employee possessor, responsible party, or ATF explosives license or permit holder.
  • Submit an application with the appropriate fee.
  • Have one year of verifiable experience in the classification being sought.
  • Have taken the Department’s training and certification class. (It is not necessary for a blaster to retake the class when adding an additional classification to a license.)
  • Have successfully passed the Department’s examination for a PA Blaster’s License in the classification being sought.

In general, anyone wishing to renew a PA Blaster’s License must:

  • Have had a minimum of 8 hours of continuing education in Department-approved courses related to blasting and safety within the 3-year period of the license.
  • Be no more than one year after the date of expiration on their license.
  • Submit their renewal form along with the appropriate fee.

If someone wishes to renew their license more than one year after the expiration date of their license they must apply for a new license.

Further information on Blaster’s License Renewal may be found at the bottom of this page.

Pennsylvania currently has the following Blaster’s License classifications:

  • General – Covers all types of above ground blasting except demolition.
  • Trenching & Construction - This license is for surface blasting for excavation not related to mining.
  • Limited – Covers limited uses of explosives above ground where the blasting is not related to excavation, such as law enforcement, research, seismic work, and industrial processes.
  • Demolition – Blaster’s license for the demolition of buildings with explosives.
  • Mine Opening – Blasting license suitable for those conducting blasting for the purpose of constructing a shaft, slope, drift or tunnel mine opening for an underground mine, either operating or under development from the surface down to the point where the mine opening connects with the mineral strata to be or being extracted.
  • Underground Industrial Minerals – License for those conducting blasting underground for the excavation of mineral resources.
