Who is responsible for knowing each actor and technical staff member, as well as fire safety procedures in a theatre?

The role that encompasses the responsibility for knowing each actor and technical staff member, as well as fire safety procedures in a theatre is the Stage Manager. The Stage Manager is a key figure in the production, serving as the primary point of communication between the entire cast and crew. They are tasked with ensuring that all safety protocols are adhered to, including fire safety, and they maintain awareness of each individual involved in the show, which is crucial for effective coordination during rehearsals and performances.

The Stage Manager also provides critical support during production, leading to smoother operations and helping to address any potential emergencies. While the other roles listed, such as Producer, Stage Door Keeper, and Scene Designer, have their specific responsibilities, they do not encompass the comprehensive oversight of personnel and safety that is essential to the role of the Stage Manager.
