The ANSI Z9.5 Laboratory Ventilation Standard describes specific best practices for the design and operation of the components of the laboratory ventilation system. Because the appendix to the OSHA Lab Standard indicates the wide range of 4–12 Air Changes per Hour (ACH) for what should be
‘‘normally adequate general ventilation’’, the need for more specific guidance arises. The LVMP outlined by the ANSI Z9.5 standard includes recommendations that an employer train employees in proper hood use; establish design, commissioning and monitoring specifications for ventilation controls; and provide criteria for the control measures of employee exposure as assessments of ‘‘specific day-to-day chemical exposure situations’’. The ANSI Z9.5 also includes the roles and responsibilities of the different stakeholders and periodic program evaluation; and specifically states in the 2012 revision that the standard ‘‘also confronts energy considerations, especially where there is a potential to impact worker health and safety.’’2 In order to address the ventilation of a laboratory from a more complete perspective, we have identified a broader group of stakeholders involved in laboratory ventilation decisions. While these stakeholders have distinct priorities and processes, they share the common goal of providing safe and efficient workplaces that support laboratory science while responsibly using energy and therefore carbon emitted by the campus facilities. The intent of this broader laboratory ventilation program is to systematize the management of laboratory ventilation to include this wider variety of stakeholders while identifying opportunities for improving facility operations and implement long-term energy conservation strategies.
