EM - A 39-year-old woman from Go Dau District, Tay Ninh Province, sustained a spinal fracture and bilateral heel fractures after the elevator she was in plunged from a height of approximately four meters.
Part 3: Heat, smoke, and elevator shaft ventilation

EM - Over time, technical studies, practical experience, and tragic incidents have demonstrated that elevator shaft vent openings do not deliver the intended effectiveness. On the contrary, they often pose critical life safety issues in the event of a fire.
Part 1: Re-evaluating the ventilation of elevator shaft

EM - Elevator and building standards, along with longstanding design conventions, have traditionally required the installation of a ventilation opening at the top of the elevator shaft. However, this requirement has recently been re-evaluated and determined to be inappropriate and largely ineffective.
Part 2: Airflow movement within the elevator shaft

EM - When ventilation openings are installed in the elevator shaft, they accelerate the movement of convective airflow between the interior and exterior of the building, thereby intensifying the stack effect and exerting a greater impact on the elevator’s operation.
Elevator density in residential buildings and calculation, selection methods

EM - Elevators have become a useful and crucial means of transportation in high-rise buildings such as residential buildings. Therefore, relevant parties need to carefully consider the calculation, selection, and installation of elevators for such buildings.
