The need for good _______ with building personnel and coworkers is necessary for the safety of everyone involved.

The correct term in this context is communication. Good communication with building personnel and coworkers is essential in ensuring a safe working environment. It allows for the clear transmission of important information regarding safety protocols, responsibilities, and any potential hazards that may arise during maintenance activities. Effective communication helps to establish a mutual understanding among all parties involved, facilitating cooperation and ensuring that everyone is aware of their roles and the procedures that need to be followed to maintain safety standards. This is particularly important in settings such as hoistway maintenance, where the presence of moving parts and potential risks to personnel can make clear communication a vital component of overall safety. Without it, misunderstandings can occur, leading to mistakes that could compromise safety.
