The correct answers are B and C because they directly measure the effectiveness, coverage, and compliance of training programs , which are key aspects of process safety performance metrics.
Option B (percentage of personnel trained on their responsibilities) is a strong leading indicator , reflecting how well the organization ensures that employees understand their process safety roles. This aligns with CCPS expectations for competency and training assurance.
Option C (percentage of workers with overdue training) is also an important metric because it highlights gaps in training compliance , signaling potential weaknesses in maintaining workforce competency. Monitoring overdue training helps prevent degradation of knowledge over time.
Option A relates to responsiveness in addressing suggestions, which is more aligned with workforce involvement or management system performance , not training. Option D reflects participation in hazard analysis , which is more indicative of workforce involvement rather than training effectiveness.
CCPS emphasizes that effective training metrics should focus on competency, completion rates, timeliness, and verification of understanding , ensuring that personnel remain capable of performing their roles safely.
