Dr. Vilem Petr has been teaching the Practical Explosives Training School (PETS) course Colorado
blasters to renew their license for over 10 years. We thought is was due time to extend our online
license renewal course offerings nationwide at PetrExplosivesGroup.com. All PETS classes are
certified with their respective state and pre-approved to fulfill the continuing education requirement.
They are also recognized by industry professional associations including the International Makers of
Explosives (IME) and the International Society of Explosive Engineers (ISEE). Here is a current list of
our online explosive license/certificate of fitness renewal course offerings.
