Under what circumstances is remedial training conducted for an operator?

Remedial training is specifically aimed at addressing deficiencies in an operator's performance or behavior that have led to unsafe practices. The correct option highlights that remedial training is conducted in response to operator-at-fault accidents, traffic violations, misused equipment, and when there's a need for additional training. This approach is designed to correct behaviors, reinforce safe operational practices, and ensure that the operator is competent and compliant with safety standards.

By focusing on specific incidents or violations, the training provides targeted interventions that help prevent future occurrences of unsafe practices. It emphasizes a proactive stance in safety management and operator development, ensuring that individuals are not only trained but also held accountable for their actions. This ultimately contributes to a safer operating environment and builds a culture of responsibility among operators.

In contrast, options that suggest remedial training only in situations like accidents or during scheduled training would not comprehensively address the broader scope of operational deficiencies that may require intervention. Remedial training is comprehensive and aimed at specific issues identified in the operator's performance.
