Check out "Overcrowding in the Instructional Space" by the NSTA Safety Advisory Board at:
http://static.nsta.org/pdfs/OvercrowdingInTheInstructionalSpace.pdf

It will address your concern.

"The definition of net area as established by the Building

Owners Management Association (BOMA) is "the total

floor area within the walls of a space. Measure length

and width from centerline-to centerline of walls (except

the exterior walls)" (BOMA Z65.1, 1996). "Net assignable

area does not include area used for public corridors,

structural elements, exterior walls, mechanical

equipment rooms, or duct and pipe shafts, toilets, and

other building support facilities. Those elements are

accounted for in building gross area " (BOMA Z65.3,

2009)."

The Occupant Load Factor is used to calculate the minimum fire safety requirements for the building/portion of the building NOT to calculate the space allotted per student in a particular room.

** External Email **

We probably face some of the same problems as many colleges and universities in terms of the number of students

that can safely occupy a general chemistry laboratory.

Information from NFPA sets 50 sq. ft. "net" per occupant. I am thinking that "net" includes benchtop working space and excludes glassware and chemical storage cabinets.

Would anyone be able to tell me if my interpretation is correct?

Thanks for any help with this.

Jack
