During which situation is a lifeguard likely to activate the emergency action plan?

A lifeguard is likely to activate the emergency action plan in situations where multiple patrons are in distress. This scenario represents a significant and immediate threat that requires coordinated emergency response procedures to ensure the safety of all individuals involved. When multiple people need immediate assistance, it can overwhelm the normal lifeguard protocols for addressing emergencies, making it crucial to implement the plan to mobilize additional resources, communicate effectively, and ensure efficient rescue operations.

In contrast, minor injuries typically do not necessitate the full activation of emergency plans, as these may be handled with less intensive first aid or intervention. A solo incident might not require the plan to be activated unless it escalates to a more severe situation, while routine checks are standard operational procedures that don't involve emergencies. Thus, in the context of rapid response scenarios requiring collective action and heightened awareness, activating the emergency action plan is essential when many patrons are in distress.
