I’d say it’s an inherent risk with most less lethal grenades. They’re ideally used out of line of sight and many have a minor incindiary element. So if they land say next to curtains they can start a fire. Like the one that occurred in the Iranian Embassy Siege after the SAS threw in a flash bang.
There’s risk mitigation that can take place but accidents will always happen to some degree.

So sounds more like a training and personal issues over equipment issue if using the right equipment limits it?
