Condensed Generic JTA
The George Mason University project team, with assistance from an MSHA SME, developed a set of generic JTAs that represent the high-level duties performed by mine supervisors in general. The overall supervisory job was categorized into twelve top duties, and each top duty is completed by sequential steps/tasks. Further, the tasks were assigned an importance rating, which was used to prioritize the most significant in regard to safety factors. The ratings include:
- 1 = Important
- 2 = Very Important
- 3 = Critical
A task labeled as “1” would have marginal safety effect if not properly completed. A level “2” task may cause significant, but non-fatal effects if not properly completed. A “3” or critical task may cause fatalities or have a catastrophic effect if not completed properly.
