Specialty Tanks






Class A Certification

Anyone involved with the decommissioning of USTs must become very familiar with and knowledgeable about those hazards, as well as the safety and health practices and procedures that must be followed in order to minimize and eliminate the potential for serious injury to people and/or damage to the environment.


Tank decommissioning includes the activities required to take a tank temporarily out-of-service, or to permanently close, remove, and dispose of the tank.


Hazards involving fire, explosion, chemical burns, inhalation of vapors during decommissioning of UST systems can cause for example:

         severe damage to internal organs

         permanent or chronic sickness and disease

         asphyxiation and death

         crushing and suffocation due to cave-ins

         severe injury from falls from height


Extreme caution should be exercised at all times during the decommissioning process.


There are specific requirements that the owner or operator must follow when temporarily or permanently taking a tank out of service.   These activities fall under the responsibility of the Class A operator, and are discussed below for situations where temporary out-of-service or permanent closure may be necessary.
