Bleacher Safety

Many athletic fields have bleachers, and they can pose serious safety risks if they are not properly taken care of. The United States Consumer Product Safety Commission (CPSC) says there were an estimated 22,100 bleacher-associated injuries treated in emergency rooms in 1999. Approximately 6,100 of these injuries were a result of the person falling from, or through, bleachers, onto the surface below. Approximately 4,910 of these falls involved children under the age of 15.

School administrators need to be aware of the potential bleacher hazards.

Bleacher Hazards

Millions of spectators watch sporting events from many types of bleachers each year. School administrators need to be aware of the following hazards:

  1. Large Gaps: Gaps of more than four inches between seatboards and footboards are considered unsafe. That is because small children can slip through them. The CPSC suggests using rigid materials to close the opening between these surfaces.
Bleachers that are not properly maintained can be safety hazards.
  1. Unsafe Guardrails: If guardrails do not properly prevent falls, they need to be replaced. Also, guardrails are often fun climbing targets for children. If the bleacher guardrails are so tall that a child can pass under it, it is not safe.
    • Guardrails should be used on any bleacher where the top row is 30 or more inches off the ground.
    • The top surface of the guardrails should be no less than 42 inches from the highest point of the bleachers.
    • Nowhere in the guardrails should a four-inch diameter sphere be able to pass through.
    • Guardrails should discourage climbing in one of three ways:
      • Only use vertical fill-ins between the top and bottom rails.
      • If there are openings in the fill-ins that could provide a foothold for climbing, the widest measurement of the opening should be limited to 1.75 inches. Opening patterns that provide a ladder effect should be avoided.
      • Use solid surfaces to fill in spaces, but only use this if the visibility would not be significantly impaired.
  1. Structural Problems: Older bleachers that have not been maintained correctly or have aged due to weather, overuse, or misuse may become structurally unsafe. Bleachers should be strong enough to handle a maximum load and be mechanically operational.
  2. Entrance & Exit: Spectators must be able to enter and leave the bleachers in a safe manner. Aisles and walkways should have non-skid surfaces and be wide enough for spectators to reach exits in an emergency.

The area underneath the bleachers can be dangerous as well. For this reason, it is important to completely block off the space underneath them. If your facility has larger rows of outdoor bleachers that cannot be closed off completely, you may want to consider having someone supervise the area to keep kids away.
