Section 8: Safety Considerations
Lightning and Severe Weather
The three-tone air horn signals immediate suspension of play, typically for lightning. Players must stop play immediately, drop the ball as it lies (or mark with a small marker), and proceed to designated shelter. Resumption of play is signaled by one short blast and a steady tone after the all-clear interval has elapsed. The USGA follows the standard 30-30 lightning rule supplemented by professional lightning-detection services at the venue.
Heat and Hydration
USGA championships are typically played in summer; heat-related risk is significant. The USGA provides:
- Water and electrolyte stations on the course
- Cooling shelters in the players' tent and at strategic course locations
- Medical observers tracking player condition
- WBGT monitoring with consultation between the Championship Committee and the medical team for heat-related modifications
Course Safety
- Spectators are managed by rope lines and trained marshals; sight-line management protects players during ball flight
- "Fore!" is the universal warning call for an errant ball; players are responsible for shouting "Fore!" when their ball travels toward people
- Players are responsible for clearing the area before taking a swing if the area is not visibly clear
Medical Coverage
- USGA championships have on-site medical staff including physicians, EMTs, and athletic trainers
- Emergency action plans are in effect at every USGA championship venue
- Defibrillators (AEDs) are positioned strategically around the course
Wildlife and Course Hazards
Players are responsible for being aware of natural hazards on the course: alligators (in southern venues), snakes, bees and stinging insects, uneven terrain, and water hazards. Players may decline to play a ball at rest in a dangerous situation (e.g., near an alligator) under the dangerous-animal interpretation; the USGA Notice to Players provides championship-specific guidance.
