An emphasis ANSI/ASSP Z establishes minimum requirements and best practices for lab ventilation systems including: Lab ventilation plans and design. The DRM specifically requires pressure-independent exhaust flow control Both require each branch of manifolded chemical fume hood duct connected to an exhaust system to be equipped with flow-regulating devices. Every laboratory will benefit from this outline of laboratory ventilation requirements and practices. However, users/operators, industrial hygienists, other safety and environmental professionals The DRM and ANSI Z permit manifolding of exhaust systems inclusive of general lab and fume hood exhaust where criteria are met. urpose Scope and ApplicationThis standard applies to the ventilation in most lab-oratories and is written for all lab. Requirements of the Standard. The Laboratory Ventilation. Users of this American National Standard aim to protect personnel from physical harm and overexposure to harmful (or potentially harmful) airborne contaminants generated within laboratories The latest version and content of the ANSI/AIHA Z standard has been completed, voted on and was approved. ratory ventilation stakeholders. An emphasis is placed on those with legal responsibilities and liability for providing a safe laboratory. The update—the first for this standard since, when AIHA was the ANSI Z9 secretariat—was directed by James ANSI/AIHA® Z– ANSI/AIHA® Z – Laboratory Ventilation Secretariat American Industrial Hygiene Association Approved ApPlease note the American Society of Safety Engineers (ASSE) is now the Secretariat of the Z9 ASC and holds the copyright to this standard.
