How many multiple occupancy suspended elements can be mounted within a single swing bay?

Multiple occupancy suspended elements are designed to accommodate more than one individual. However, since each swing bay is designed to accommodate only one person at a time, it is not safe or recommended to mount more than one multiple occupancy suspended element within a single swing bay as it can cause overcrowding and increase the risk of accidents. Therefore, the correct answer is only one. The other options (B, C, D) are incorrect because mounting more than one element in a single swing bay goes against safety regulations and can potentially lead to harm for the users.
