Laboratory Design and Certification; Three Critical Criteria

| January 11, 2018

Safety is the first design criterion when designing a laboratory and this document will help provide options and resources for stakeholder decision making. Ventilation, Fume Hood Certification and Maximum Allowable Quantity Evaluations are just a few of the major safety considerations during the design process that the Guide addresses. Every laboratory must be evaluated individually, and there are several other safety criteria that need to be reviewed when designing a laboratory; however, these three topics are crucial for laboratory safety and functionality.

  • Laboratory ventilation is highly variable and sometimes difficult to determine. The Guide outlines the main codes, standards and regulations to help the designers, lab users, stakeholders and authority having jurisdiction (AHJ) make the best decisions.
  • The fume hood certification process is also discussed within the Guide, and describes each prescriptive fume hood certification test, as outlined in ASHRAE Standard 110 – 1995 (Updated in 2016), Method of Testing Performance of Laboratory Fume Hoods. Although passing criteria must be evaluated by lab users, designers and safety officials; the Guide provides some typical passing criteria that may be used for reference.
  • Lastly, Maximum Allowable Quantity (MAQ) is reviewed within the Guide. Strategies for meeting the acceptable limits for hazardous materials within typical buildings is presented.
