I have a question in regard to exit devices (crash bars) on gates at a school. The gates in question are not very tall, and kids with heavy backpacks can swing their backpacks over the gates and open the gates from the outside by hitting the crash bar. Is it legal, or within code, to weld/bolt something across the top of the crash bar so it can't be pushed in/opened in that manner? To exit, you'd have to push with your thumbs instead of "crashing" into the whole bar.
Thoughts? Ideas? Alternatives? Short of replacing 20 gates with taller gates.
These all exit from the schools out into parking lots, etc.
