What key factors should a court monitor look out for at all times? Select all that apply.

In the context of a court monitoring for safety, essential factors include the behavior and safety practices of participants, as well as the equipment they are using. Athletic ability, while important in some settings, does not inherently relate to the safety of the environment or the well-being of participants.

When monitoring a court, factors such as horseplay, double bouncing, and footwear safety are crucial for ensuring a safe environment. Horseplay can lead to accidents and injuries among participants as it often involves rough or unregulated play. Double bouncing refers to the action of one individual jumping on a trampoline while another is already on it, which can create unpredictable jumps and increase the risk of injuries. Footwear safety is critical as inappropriate footwear can lead to slips, falls, or instability during activities on the court.

While athletic ability may influence a participant's competence, it does not directly relate to safety monitoring; therefore, it is not a key factor that should be prioritized when assessing safety in an urban air environment.
