When possible, the planning of laboratories should start with
the inside and work outwards. This means that laboratory
equipment should be laid-out first, then the space and the
equipment and appliances for the building, and lastly, the
building itself. This is the only way to ensure that the
facility is oriented to the processes and the requirements of
The following data and questions are ascertained and
considered in a specification sheet:
Type and frequency of the work processes
Surfaces for test procedures
Number of personnel working in the laboratory
Number of evaluation/writing stations
Which chemicals, consumables, process materials are
Required sanitary and electrical media with indication
Storage space requirements
How are logistics planned for the laboratory?
Disposal of chemicals
Number of required rooms, secondary rooms and common
Then the approved specification sheet is worked into a room
data sheet, in which a quantitative and qualitative
specification for the laboratory space and laboratory
equipment are put together.
An precise definition of the interfaces is
How will lines/pipes be routed in the building?
How will media be brought into the laboratory?
Will media such as vacuum or compressed air be generated
centrally or locally?
Where are the transfer points?
Who will connect the lines to the cut-off valve?
Who will safeguard the electrical circuits and connect
electrical lines to terminals?
What volume of air is required?
How high is the air exchange rate?
Are exhaust hoods with variable volumetric flow rates
Are the rooms air-conditioned?
Who will be responsible for the regulation of the room
air in the laboratory?
How much of a factor is heat generation from devices,
Who will connect exhaust hoods and cupboards with forced
ventilation to the ventilation system?
Detailed planning of laboratory equipment:
Which tabletop material is required and/or sufficient?
Which media (sanitation, electrical) will be required at
the table and what should the quality of such media be?
Should shelves or wall mounted cupboards be integrated?
Which base cupboards will be needed?
Should wash basins be integrated or will separate sinks
Which devices, consumables and other implements need to
Will space be required for the storage of documentation,
Are ventilated cupboards such as acid/alkaline storage
cupboards, compressed gas cylinder cupboards, solvent
cupboards or chemical cupboards required?
Laboratory exhaust hoods:
Specification of hood type based on the height of the
room and the work to be conducted
Which media will be needed?
Constant or variable exhaust air?
Is special cladding such as ceramic, polypropylene or
stainless steel required due to the use of corrosive
Are shuttle valves needed in the side wall of the hood
for the routing of cables?
The guidelines for laboratories were created by the German
Federation of the statutory accident insurance institutions
for the industrial sector, technical chemical committee and
cover protective measures for the hazards associated with
general operations in laboratories. They also address the
construction and furnishing of laboratories. Information
about the following subjects is also provided:
Operational and traffic routes
Work surface in front of the laboratory table or exhaust
hood: 450 mm
Traffic area between 2 work surfaces: 550 mm
Doors: Must open outwards and be fitted with a
Ventilation: Laboratories must be fitted with
sufficient forced ventilation systems which are effective
at all times.
Storage space for hazardous substances: Must be
connected to a sufficiently dimensioned ventilation
system which is effective at all times.
Full body showers: A shower connected to a water
supply (preferably potable water) must be installed at
the exit of all laboratories.
Eye showers: An eye shower connected to a potable
water supply must be installed in all laboratories.
