Who is responsible for the safe condition of the piste?

The correct response highlights the shared responsibility for ensuring the safe condition of the piste between the event organizer and the referee. The event organizer has the primary obligation to provide a safe and suitable environment for competition, which includes ensuring that the piste is free from hazards, properly maintained, and meets safety regulations. However, it is critical for the referee to conduct a thorough check of the piste prior to the start of the competition to identify any potential issues that may have been overlooked. This dual responsibility ensures that both event management and officiating are aligned in prioritizing the safety of all participants, fostering a competitive environment where athletes can perform without the risk of injury due to unsafe conditions.

The other options do not provide a comprehensive view of safety responsibility in this context. For instance, if only the referee were responsible, this would place undue burden on a single individual, whereas relying solely on fencers or other parties such as coaches and trainers does not cover the complete oversight required to manage competition safety effectively.
