With regard to equipment, first and foremost, one of our largest assets is actually our dangerous goods officers who are qualified out of Pueblo, Colorado, to the highest level, and they are scattered throughout. What we've done is enter into a lot of agreements with companies. As an example, if we have a flammable liquid fire, we already have arrangements with Irving Oil’s contractor. We have arrangements with Valero, out of Quebec. We have arrangements with railroads, in terms of equipment. We have our own specialized equipment for burying goods.
You have to understand that when it comes to dangerous goods, it's not only about crude oil. We handle about 500,000 carloads of dangerous goods and we have for a very long time. Crude oil is less than 2% of our business, so when we talk about dangerous goods, we're talking about the full facet. We call in many different suppliers who can assist from an environmental standpoint. We can't neglect that. Not everything burns; things can spill to the ground. We have environmental caches of equipment strategically located throughout our network for that first response, whether it is booms, river rafts to put booms in place, absorbent materials, and so forth.
We have multiple layers but we also have a vast network of experts. We’ve had incidents where I've had five planes in the air bringing in people from all over North America. It's not a five-alarm fire for us; it's a ten-alarm fire for us. We will bring in as many people as needed. As Mr. Creel said earlier, you ramp up through a situation, so if you're in northern Ontario, that time of response, you ramp up.
