RT-160a found that shutdowns, turnarounds, or outages benefit from the safety factors referenced in Key Finding #2, but their unique characteristics benefit from additional safety factors, specifically: (RS160a-1, p. 5)
- Finding workers from similar company projects who are already familiar with the type of work.
- Smaller scheduling time units provide more detailed planning, which enhances safety performance.
- Hire workers in advance to provide training and become acclimated to the worksite.
- Shorter work weeks and project duration, with work weeks no longer than six twelve-hour days, minimizes the impact of fatigue.
- Smaller crew size or ratio of workers to supervisors.
- Incentivized contracts for good safety performance.
