A biohazard safety enclosure or workstation particularly adapted for enclosing automated instrumentation includes a chamber defined by front, back, top, bottom, and opposed end walls; a HEPA filter across an air inlet opening into the chamber, and an airflow means to direct air horizontally through at least part of the chamber between the end walls. Preferably, the workstation has a second HEPA filter across an air outlet opening in the work chamber, with the airflow means including a conduit extending from the air outlet opening to the air inlet opening. A fan draws air through the conduit. A part of the filtered air is exhausted from the workstation and is replenished through a make-up air inlet into the chamber.
