Lab Design Considerations

 
modern research laboratory A laboratory is a space devoted to education, analysis, research, experimentation, and production.  Laboratories handle a variety of different materials, from gases and chemicals, from drugs to living materials.

Laboratories vary significantly depending upon several factors, including their intended function, the types of materials that will be handled in them, and how many people they will accommodate.  To that end, the design of a laboratory is extremely important.

The first consideration when designing a laboratory is selecting a site.  When siting a lab, it's important to review important criteria such as the health and safety of the population in the surrounding area of the laboratory, public perception, and environmental concerns, as well as engineering and operations plans.  The impact of both building and operating the laboratory should be examined carefully.  Sites should be chosen so that accidental contamination will have the smallest effect possible and will be able to be dealt with expediently.

Lot size and topography are also important to choosing a laboratory site, as are zoning and covenant requirements and restrictions.  The laboratory should be accessible, properly sized, and conveniently located near — or have easy access to — all suppliers.

Once a site is chosen, the next step is to design the laboratory room(s).  The first order of business during this step is to determine the preferred room arrangement based on data collected.  Things that should be taken into consideration include room size(s) and hood requirements, and how those will affect the room's layout, as well as the locations of exit doors, eye washes, and emergency showers.  Another thing that must be determined during this stage is the fire and explosive hazard levels of each room.  This information will be incorporated into the architectural planning in order to ensure that the lab design is not only efficient, but safe.

There are several principles that should be considered during the design phase of a laboratory facility.  For example, functions, hazards, and risks will all have to be identified, so that laboratory activities can be grouped or separated as needed.  Things like wind direction, and potential cross-contamination between rooms, blocks, and wings, should be taken into consideration, as should the relationship between fresh-air intakes and exhaust stacks.

While it may seem peripheral, at this stage it is important to determine the materials to be used in framing, windows, exterior and interior doors, and corridors.  These will mostly be determined by the type of work being done in the laboratory, as well as the type of materials that these areas will be exposed to.  Depending upon the use of the laboratory, some materials will be safer and more efficient than others.

When designing a laboratory, it always makes sense to call on the services of architects and engineers who specialize in this type of building.  There are many issues that are specific to the design and construction of laboratories, and many complex problems to solve.  Using qualified professionals will help to ensure the safety and efficiency of the laboratory, regardless of its intended use.
