For the safety of the participants, each unit requires at least one adult supervisor at all times. For our larger pieces, such as slides and obstacle courses, at least two adult supervisors are required. (Depending the size of the slide) . Adult supervision must be all times. Accidents on equipment generally happened due to two things: too many children on the unit or the unit was not kept secured. Supervisors should monitor the amount of children and make sure they're acting in a responsible manner. Supervisor also should check the equipment for secureness to the ground. Safety is really important no matter how small or big is the event, if you need a trained supervisor we can provide one for an extra fee.
