Sometimes firefighters are not able to enter the scene of a fire through
a door or window. In instances like these, they have to cut through a
wall and make an opening big enough to enter the establishment and make a
rescue. Bearing in mind that most structures are concrete block, it can
seem like it would take a long time to break an opening large enough to
complete this task. During their training, firefighters need to make an opening, rescue a victim and another firefighter if they are trapped in the blaze, and exit the establishment in less than 2 minutes.
