If you or someone else experience an emergency situation while at the beach, stay calm and alert those around you of the situation. If possible, call for medical assistance as soon as possible and provide any necessary first aid until help arrives. Additionally, make sure to contact local authorities or lifeguards on duty in case they have additional resources available which could be useful in such a situation. Finally, try not to panic and remain as composed as possible so that everyone can work together towards finding a resolution safely and quickly.
