Lab Safety Design Standard
Preface This document has been assembled by the Vancouver Island University, Department of Health and
Safety Services. This document specifically pertains to the built environment of laboratories and not
operational practices. This document should be read and understood by all parties involved in lab
development. Please refer to the Roles section to learn more.
Scope These are design and construction standards to be applied to new construction and renovation of
facilities containing teaching and research laboratories and clinics at Vancouver Island University. For
renovations of existing laboratories or new laboratories in existing buildings not all standards will be
practical to implement, such as changing existing building ventilation systems. For this and other
provisions H&SS will provide exemptions on a case by case basis. H&SS must be consulted in the
commissioning of new labs and all renovations to existing labs.
Roles
Health and Safety Services Establishes standards to ensure compliance with legislation governing laboratory activities
within all of the following: the applicable municipality, the province of British Columbia,
and Canada. H&SS ensures that compliance is met when commissioning of laboratories is
executed.
Principal Investigators (PI) and faculty Determines the research activities to be carried out in the lab. Principal Investigators must
ensure that the design of lab space complies with the requirements of university, provincial
and federal safety legislation applicable to the research activities. Refer to the Definitions
section to find some of the applicable standards.
Space Designers (Project Manager, Project Planners and/or Architects) Coordinates the requirements of this standard, other applicable standards and/or guidelines
with H&SS, the Faculty or Principle Investigators and the contracted constructor, designer or
other provider. Space Designers are to facilitate the requirements indicated above, the needs
of the Faculty or PI and costs in execution of the laboratory construction.

Comfort Chairs that have all the features described in this document may still vary in comfort. A chair test or
demo, ideally under actual working conditions, is helpful in determining whether a chair will truly be
comfortable for an employee and should be explored if possible.
Ease of adjustment If more than one person will be using a chair or to obtain an optimum fit for an individual, a chair
should be able to be adjusted easily.
Chair adjustment controls should:
• Be operable while sitting in the chair
• Be logical in placement and direction of activation
• Have control markings that are visible from a seated position or be distinguishable by some other
means (e.g. different shapes)
19 | P a g e
• Not require undue force for activation
• Be designed to prevent unintentional activation
Warranty
Chairs should include a lifetime warranty. Repairs should be timely within a 1-2 week window after
the initial request is made and the request should be simple and efficient with one contact person.
