Final answer:
On-site building staff should have knowledge of elevator safety requirements, maintenance protocols, and understanding of structural support influenced by gravity changes, as well as company protocols like security and dress codes.
Step-by-step explanation:
On-site building staff members, such as maintenance and facility managers, should possess a clear understanding of several aspects related to the elevators in their building. It is essential to know about the safety requirements associated with elevators, including where to locate emergency equipment like fire extinguishers and first aid stations. Staff should be familiar with the operation of elevators and aware of maintenance protocols, access to service areas, and the proper procedures for evacuating passengers in the case of an emergency. Additionally, understanding the structural support required for elevators, which takes into account factors like changes in the value of gravity (g) at different heights, is crucial for ensuring the safe and efficient operation of these systems. Engineers must consider Earth's gravity and other forces, such as those resulting from Earth's rotation, when designing elevators and their structural components within very tall buildings.
Regarding the use of elevators for transporting goods, for example, staff should be aware of the work involved when moving items to different floors and the impact of factors like friction. Knowledge of elevator mechanics and forces, such as calculating the tension in the elevator cable when moving passengers or cargo, is also pertinent. Awareness of company protocols, including security protocols and dress codes, complements this knowledge and ensures a well-prepared on-site staff.
