Which method is commonly used to isolate a fire hazard?

Isolating a fire hazard involves taking specific actions that prevent the fire risk from spreading or causing harm. This can include removing combustible materials from the area, securing the environment to limit access, and ensuring that any potential ignition sources are controlled. When a hazard is isolated properly, it minimizes the risk of a fire starting or escalating, allowing for a safer environment for personnel and property.

Blocking entrances, shutting off power, and notifying personnel can be part of a broader fire safety strategy but do not directly equate to isolation of the hazard itself. Blocking entrances may restrict access but doesn't necessarily mitigate the hazard. Shutting off power might prevent equipment from igniting, but it doesn't address other potential fire risks in the area. Notifying personnel is crucial for awareness and safety protocols but does not directly contribute to controlling or isolating a fire hazard. Thus, isolating the hazard is the most effective and direct method for managing fire risks.
