Try to attend public fireworks displays.
For, the shows are safer and are meant for better displays
than what might be achieved at your home.
However, if you must use fireworks, be sure to follow certain safety rules.

Remember:
Each year people suffer burns, loss of eyesight,
burst eardrums and other injuries, and property is damaged because of fireworks.

Words of caution:
Common fireworks are explosives
and must be handled with care and respect
to prevent injury and property damage.
