The backdraft is a well known phenomenon in the fire service; what isn’t well known is how often the occurrence takes place on the fireground. In many instances, a rapid fire incident takes place with such speed, that witnesses are left wondering exactly what happened. The backdraft occurs in an oxygen starved atmosphere and can be exceptionally violent. As this week’s report describes, even overhaul situations are not exempt from surprises.

The lessons learned section of this featured firefighting report mentions maintaining situational awareness and accountability. When fire is discovered in a confined space, no matter how small or lazy it appears, it must be extinguished quickly.

Once you have read the entire account (CLICK HERE), consider the following:
1. What equipment do you consider the minimum for handling fire in concealed spaces?
2. Based on the description in this report, would you describe the phenomenon as a backdraft or flashover? What leads you to your conclusion?
3. How often are you partnered with a member from another unit?
4. The thicker and darker the smoke, the (more or less) combustible it is.
5. When opening walls and ceilings, which type of hook (pike pole, drywall, all purpose, etc.) do you prefer and why?
