A pre-job briefing should take place whenever there is a significant change in working conditions because it ensures that all team members are aware of potential hazards, updated procedures, and any new information that may impact safety. This proactive approach helps to maintain a high level of safety and communication among team members, which is crucial in hazardous environments. By addressing changes in conditions, such as new equipment, alterations to the worksite, or unexpected hazards, the team can adapt their strategies and minimize risks effectively.

Conducting a briefing at the end of a job, at the beginning of the month, or every morning without regard to changes in the work conditions does not specifically focus on the immediate and relevant safety concerns that can arise during operations. The emphasis on significant changes underscores the importance of staying alert to variable risks inherent in hazardous waste operations.
