Air Hockey safety has been an issue for years. Air Hocky is a terrific "staple" game for today's FEC's. We put it in our client's game lists wherever we have the space. However there is a real concern about pucks flying off the table (see below for an extreme but real case of what can happen when they do). There are two primary ways to minimize risk from flying pucks: 1) install and maintain in good repair the puck guards that are available from every majot manufacturer; 2) place the game with ends "pointed" away from traffic aisles.

What lousy puck!
A woman is suing Chuck E. Cheese after allegedly being hit in the head with an air hockey puck at the children's entertainment joint.
Reyna Mason claims that a stray puck struck her in the head while she was sitting in a booth near the air hockey table on February 22, 2008, according to a lawsuit filed in Cook County Circuit Court.
The average commercial hockey puck is a little over 3-inches in diameter and weighs anywhere from 8 to 16 grams.
