From The Division of State Fire Marshall:
"It is a common practice for mining companies to use explosives as they extract sand and limestone from Florida soil. These materials are used to make construction components such as aggregates, sand, cement and roadbase materials. The use of explosives is governed by Florida law. Chapter 69A-2, Florida Administrative Code, provides the rules governing the use of explosives in the state.
To use explosives, a firm must have a permit issued by the Regulatory Licensing Section, Division of State Fire Marshal, Department of Financial Services. All blasting activities must be monitored by a seismologist.
Refer to the brochure, Blasting in Florida, for more information."
