If I may, I'm going to try to get through six or seven questions. I only have six minutes. I appreciate the information.
I shared with you, prior to the meeting, a page from an emergency response guidebook to which Transport Canada contributes. The table on page 359 talks about BLEVE, or boiling liquid expanding vapour explosion. I'm sure that, as the director general for transportation of dangerous goods, you're familiar with these events. They are extremely high-consequence events with massive destructive force.
I'm wondering if you could, based on the table—the way I read it—share with the committee the minimum time to BLEVE failure for a tank car experiencing full torch conditions. This would be a tank car with 140,000 litres of dangerous goods, such as propane, on board.
