Laboratory Biosafety Cabinet Exhaust Coordination

Biosafety cabinet exhaust and lab ventilation are controlled systems with containment and balancing requirements.

Stop if

• This serves a biosafety cabinet/lab exhaust. Do we need a dedicated detail, material, and TAB/certification hold point?

Watch out

• Do not connect, cap, or reroute lab exhaust without approved detail and lab controls direction.

Check

• Confirm cabinet type, dedicated/exhaust connection, material, airflow direction, controls/TAB, and certification requirements.

Steps

• Identify whether this is normal ductwork or a controlled/special condition.
• Confirm cabinet type, dedicated/exhaust connection, material, airflow direction, controls/TAB, and certification requirements.
• Get the current drawing/detail/spec/submittal before changing routing, material, access, or support.
• Bring photos, location, and what you checked to the foreman before closing or covering the work.
