In this unit students will learn the proper methods for responding to and reporting on events or situations that could compromise the wellsite environment. While no one plans for there to be a wellsite accident such as a leak or spill, it is nonetheless important to understand the procedures for handling these types of situations if they occur. Each rig has specific policies in place for responding to disasters, and this module is not meant to replace these. Rather, it serves to emphasize the importance of general attentiveness when on the jobsite and to introduce response procedures common to all wellsites.
