Need Colorado explosives training but not the full five-day Quarry Academy? You can register separately for our 2-day Colorado Practical Explosives Training School (PETS).
This instructor-led course provides 16 hours of explosives safety and regulatory training for individuals who handle, store, transport, and use explosives.
PETS is designed for both new and experienced professionals, including those preparing for applicable Colorado explosives permit requirements or seeking to refresh their safety knowledge.
The PETS-only option covers the final two days of the Quarry Academy. You do not need to attend or pay for the first three days.
PETS provides training relevant to Colorado explosives permit requirements. Completion of training does not automatically qualify an individual for a state permit; additional state requirements may apply.
Choose the Full 5-Day Academy ($2,950) if you want comprehensive training in quarry operations, equipment, drilling, blasting, and explosives safety.
Choose the 2-Day Colorado PETS ($795) if you only need explosives safety training for blasters, continuing education, or training relevant to Colorado permit requirements.
Both courses are taught in person in Golden, Colorado. Seats are limited.
