- play BB on a flat and levelled surface/court.
- make sure to way sports shoes to get a good grip.
- let there be a coach near the court observing everythin so that in case of emergency some elderly person is ready to help.
- make sure to have a proper dress code .
- play indoors during the rains and ask faculty to clean the water on the court just incase..
