This clip from the 1970s shows a day at an American blood bank. 

Begins with the door sign “BLOOD BANK.”

A woman wearing a white lab coat sits at a work table, making labels and removing vials from a machine.

A quiet, elongated room is populated with a few people, busy with work.

A short-haired Asian woman fills out a form. Beside her, about a dozen vials sit in a blue tray.

An Asian man wearing a plaid shirt types on a large computer.

A middle-aged-looking white woman, wearing glasses and a lab coat, reviews a stack of paperwork. On the shelves, in the background of the shot, are binders, small equipment parts, and likely trays of blood technology. Later we see this same woman using various pieces of equipment; perhaps she is in the process of testing blood samples or testing the functionality of the equipment.
