I am sure I posted this at some point, but it was recently posted again to YouTube:
Firefighters on YouTube writes: The Washington Township Volunteer Fire Co. was battling a house fire and ventilating the roof, when things got really hairy: As the firefighter was cutting a hole into the roof, the roof all of a sudden partially collapsed during this operation. This clearly shows why it’s standard operating procedure to have a team of two firefighters on the roof for ventilation. One man opens the roof, the second man acts as safety and observes the procedure to notice even small changes to avoid such incidents.
This Washington Township Lehigh County house fire took place on June 21 2011 and luckily the firefighter got away with just the scare.
