See Section 4.2 for chemical handling procedures to be followed when handling corrosive materials. JSAs for specific work tasks will be developed in the field. They will be appropriate for site conditions and will be reviewed during daily tailgate safety meetings. Any JSAs developed for ongoing operations will be included in Appendix A. See Section 3.1 for general guidelines that are common to most projects. Any change in the scope of work will require an amendment to this HASP. Any task conducted beyond the scope of work identified in this HASP must be evaluated using the JSA process. The PM and Site Manager (SM) will be responsible for identifying conditions that are beyond the scope of work and communicating to the SHSO. The SHSOs will provide guidance in the development of JSAs. See Appendix A for the JSA format AMS-710-05-FM-01708. The completed JSAs must accompany the HASP. A JSA, according to APTIM policy, will be completed daily for each task by the site supervisor or foreman responsible for the task(s). The SHSO will facilitate the process and help guide the supervisor in correctly assessing each task for the proper hazards and controls.JSAs are completed in-depth at the beginning of each task identified herein, and for new tasks that develop. However, as the work progresses, the JSAs are modified each day to address changes in work practices, site conditions, process changes, or unusual occurrences. If no modifications are necessary, the JSAs must still be completed, noting such. As work changes can happen at any time, these JSAs may be necessary to be modified more than once a day per task.The JSA must remain with the work crews until task is completed. 2-5
