What is an example of a fire fighting system?

A portable fire extinguisher is a prime example of a fire fighting system because it is specifically designed to combat small fires in their early stages. These extinguishers are equipped with various agents, such as water, foam, dry chemical, and CO2, tailored for different types of fires. Their mobility and ease of use empower individuals to take immediate action in case of a fire, thereby enhancing safety and minimizing potential damage.

In contrast, while the other options play crucial roles in building safety, they do not function as fire fighting systems. CCTV cameras are primarily used for surveillance and security purposes; they monitor areas but do not directly extinguish or address fire incidents. Emergency lighting provides illumination to help guide people safely out of a building during an emergency, but it is not a tool for fighting fires. Telephone systems facilitate communication during emergencies, but like the others, they do not actively intervene in fire scenarios.
