Where are you? Never heard that before, but:
1. Look for the acrylics, plastics, etc.
2. At least secure every glass that is not needed to be used to its tray, shelf, table, etc.
3. Use as heavy glass as you can (not always the cheapest) if you must.
4. Have asm or other actors ready to make sudden appearance as maid, etc w/ broom and pan. There is just nothing worse than broken glass on stage.... well, fire, smoke, weapons, xplosives.... but still, it is an avoidable accident waiting to happen, so work with director and designer to use subs if you can.
