This standard describes required and recommended practices for the design and oper-ation of laboratory ventilation systems used for contr
31、ol of exposure to airborne contaminants. It is intend-ed for use by employers, architects, industrial hygienists, safety engineers, Chemical Hygiene Officers,Environmental Health and Safety Professionals, ventilation system designers, facilities engineers, mainte-nance personnel, and testing and bal
32、ance personnel. It is compatible with the ACGIHIndustrialVentilation: A Manual of Recommended Practices, ASHRAE ventilation standards, and other recognizedstandards of good practice.HOW TO READ THIS STANDARD. The standard is presented in a two-column format. The left col-umn represents the requireme
33、nts of the standard as expressed by the use of “shall.”The right col-umn provides description and explanation of the requirements and suggested good practices orexamples as expressed by the use of “should.” Appendices 1 and 2 provide supplementary infor-mation on definitions and references. Appendix
34、 3 provides more detailed information on stackdesign. Appendix 4 provides a sample audit document and Appendix 5 presents a sample table ofcontents for a Laboratory Ventilation Management Plan.Flexibility. Requirements should be considered minimum criteria and can be adapted to the needs of theUser
35、establishment. It is the intent of the standard to allow and encourage innovation provided the mainobjective of the standard, “control of exposure to airborne contaminants,” is met. Demonstrably equal orbetter approaches are acceptable. When standard provisions are in conflict, the more stringent ap
36、plies.Response and Update. Please contact the standards coordinator at AIHA, 3141 Fairview Park Drive,Suite 777, Falls Church, VA 22042, if you have questions, comments, or suggestions. As with all ANSIstandards, this is a “work in progress.” Future versions of the standard will incorporate suggesti
37、ons andrecommendations submitted by its Users and others. This standard was processed and approved for submittal to ANSI by the Z9 Accredited StandardsCommittee on Health and Safety Standards for Ventilation Systems. Committee approval of the standarddoes not necessarily imply that all committee mem
38、bers voted for its approval. At the time it approved thisstandard the Z9 Committee had the following members:Thomas Smith, ChairTheodore Knutson, Vice ChairDavid Hicks, Secretariat RepresentativeAt the time of publication, the Secretariat Representative was David Hicks.Organization Represented . . .

45、st lab-oratories and is written for all laboratory ventilationstakeholders. An emphasis is placed on those withlegal responsibilities and liability for providing asafe laboratory. However, users/operators, industri-al hygienists, other safety and environmental pro-fessionals will also find the stand
46、ard written fortheir needs.The standard cannot establish strict liability in allcases but does attempt to fix accountability in manyrelationships that exist with its context. Please notethat such relationships are defined throughout thestandard and generally encompass the following:administration -
47、occupant; employer - employee;management - staff; owner - occupant; owner - tenant;teacher - student; designer - owner, etc.This standard does not apply to the following typesof laboratories or hoods except as it may relate togeneral laboratory ventilation: animal facilities, biosafety cabinets, exp
48、losives laboratories, high containment facilities (e.g., BSL 3, BSL 4,facilities operating under “chemical suretyplans,” etc.), laminar flow hoods and isolators (e.g., a cleanbench for product protection, not employeeprotection), and radioisotope laboratories.General laboratory safety practices are
49、not includ-ed except where they may relate to the ventilationsystems proper function or effectiveness.Clarification and Explanation of the RequirementsLaboratories conduct teaching, research, qualitycontrol, and related activities and should satisfyseveral general objectives, in addition to being suit-ed for the intended use they should be energy efficient without sacrificing safety,compliance, or space condition requirements, be safe places to work, comply with environmental, health, and safetyregulations, and meet any necessary criteria for the occupantsand techno
