Whether it's a large chance or a small chance, it's a chance, and so, it's an urgent situation.

We're seeing more and more residential sprinkler systems, where people are putting them in their homes.

We would hope that all of them have been replaced. But based on the numbers, that's probably not the case, there are still some of those heads out there.

It's urgent we rectify this situation.

Whenever you have a large number of people in a building you want to make sure they can get out very quickly. So they need to know where the exits are and they need to know how to get to them.

In a situation like that, time is of the essence. And any delay to that can put the patient in jeopardy. In this situation, the firefighters were also in jeopardy.
