What is an essential technique for removing large glass block windows?

Removing large glass block windows can be a challenging task due to their weight and the way they are typically installed. Breaking a side column and the bottom row is an essential technique because it allows for better control and stability when dismantling the window. By starting with the side column, you can create a structural weakness that can lead to the effective removal of the entire block without risking the safety of the operator or potential damage to surrounding structures.

Additionally, breaking the bottom row provides leverage and makes it easier to lift remaining blocks out. This technique minimizes the risk of shards falling and potentially injuring the individual performing the removal, as well as reducing the chance of debris scattering if the blocks break unevenly.

Overall, this method emphasizes safety and efficiency, making it the preferred approach when handling large glass block windows in a firefighting or emergency response scenario.
