Final answer:
Shutting off power for emergency responders' safety is part of the mitigation stage in hazard control, which includes actions like mandated blackouts in crises to protect infrastructure and personnel.
Step-by-step explanation:
Shutting off power to protect emergency responders is an action taken as part of the mitigation stage of hazard control. This stage involves measures that are designed to prevent hazards from occurring or to reduce the impacts of hazards that do occur. For instance, during a natural disaster such as a severe winter storm or in the face of a potential invasion, government officials can mandate blackouts to ensure the safety of emergency responders and the general population. These blackouts prevent further accidents and safeguard those on the ground, especially when they are immersed in dangerous situations like navigating through debris or dealing with electrical hazards after a storm or a civil disturbance. Actions like blackouts that preserve infrastructure and personnel are key in building the resilience of civil defense and emergency preparedness measures, a crucial aspect for ensuring public safety during times of crisis.
