When warranted, what must an employer provide to ensure adequate protection to life during fire emergencies?

The correct response highlights the importance of having a dedicated fire-fighting organization in place within an employer's safety protocols. This measure ensures that there are personnel specifically trained and equipped to handle fire emergencies effectively. In the event of a fire, having such a team is crucial for the immediate response needed to protect the lives of employees and minimize property damage. The existence of a trained fire-fighting organization means that there are resources available to combat fire risks directly and provide guidance during emergencies.

In comparison to the other options, while having a trained first-aid team is important for addressing medical emergencies, and emergency evacuation signs are essential for directing personnel safely out of the building, these measures do not focus directly on fire response. A safety officer plays a critical role in overall workplace safety but may not specifically address fire situations unless they are part of a broader emergency management plan. Therefore, establishing a fire-fighting organization specifically targets the unique challenges posed by fire emergencies, making it the most relevant choice for ensuring adequate protection to life during such events.
