What is the minimum back-to-back distance between open-air seats with backrests according to PD 1096?

The minimum back-to-back distance between open-air seats with backrests as specified in PD 1096 is 750 mm. This requirement is fundamental in ensuring comfort and accessibility for users in public spaces, such as theaters or stadiums. The distance allows enough space for individuals to sit comfortably without their backs touching those of adjacent seats, facilitating ease of movement and reducing the likelihood of congestion. This regulation is important not only for user comfort but also for safety and compliance with building standards.

Understanding this measure is vital for those involved in seating arrangements and design in public venues, as it contributes to creating a pleasant and inclusive environment. The other distances provided in the options may be based on different contexts or outdated regulations, emphasizing the importance of referencing the specific legal standards in place, like PD 1096, for accurate design compliance.
