Final answer:
When switching strategies, it is important to maintain situational awareness, abandon hose lines if necessary, and avoid splitting away from the team. The answer is option D.
Step-by-step explanation:
When switching strategies, it is important to follow certain guidelines to ensure effective decision-making and coordination. One important guideline is to maintain situational awareness to recognize changes in fire behavior or any other relevant factors. This can help inform the decision to switch strategies and adapt to new circumstances.
Another guideline is to abandon hose lines when a strategy change is made. This is because the objectives and tactics may change, requiring a different approach that may not involve the use of hose lines.
However, it is not recommended to split away from the team when switching strategies. Instead, it is important to work together and maintain coordination with the team to cover more ground and ensure efficient execution of the new strategy.
