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.

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

We're very grateful for their participation. We want to raise the profile so people know the importance of moving to the right and yielding to emergency vehicles.

We've had people in the past bring their propane barbecues inside to heat their home. That presents a huge carbon monoxide poisoning hazard, as well as a fire hazard.
