What is the minimum back-to-back distance between open-air seats with no backrests according to PD 1096?

The minimum back-to-back distance between open-air seats with no backrests, as specified in PD 1096, is indeed 600 mm. This measurement is important for maintaining comfort and accessibility for individuals using the seating. Proper spacing ensures that occupants have adequate room to sit without feeling cramped, and it also facilitates ease of movement, particularly in environments such as theaters, stadiums, and public gatherings.

The standard of 600 mm allows for a balance between maximizing seating capacity and ensuring that the experience for individuals is not compromised by overcrowding. In contexts where seats lack backrests, this distance becomes vital as it mitigates the risk of discomfort or injury due to limited space. Overall, adherence to this requirement helps to establish a safe and enjoyable environment for all users.
