Therefore, we must respond and intervene as soon as possible to reach the sites of fire accidents.

Then, identifying the residential areas that are not covered within four minutes as a response time for the arrival of civil defense vehicles to the site of the fire.

The results indicate that 22.7% of the residential areas in the city of Hail are included by the response time range of four minutes.

This means that 77.3% of the residential areas are not served within the specified response time range of four minutes.

Therefore, new civil defense centers were proposed to remedy situation, as five civil defense centers were added, covering 40.2% of the total number of residential areas, and to achieve the total coverage, many centers have been established to exceed the five pro posed centers.
