Hazard Classifications for Laboratories
Andrew A. Dymek, PE, Newcomb &
In order to improve safety while reducing unneeded costs, laboratories
need to be right sized. To do this, a classification system is needed
to determine the correct level of safety and, from this, determine
the correct criteria for design. There are many industry standards,
which go unchallenged at the time of programming and design that
have a large impact on first and operating costs for a laboratory.
While all laboratories are not used equally, they are designed equally.
High air change rates and non-recirculating air systems are common
criteria for a "laboratory", but there are many cases
where this criteria is wasteful if not needed for health safety.
Conversely, there may be certain cases where the industry standards
may not be safe enough. This presentation will review industry code
and guideline standards and their results on design, and then propose
a hazard classification system to right size laboratories.
At this time there are no classification systems. The presentation
will discuss why we need classifications and how we can incorporate
the Labs21 Approach.
Andrew Dymek, PE, earned his Bachelor of Mechanical
Engineering degree from the Georgia Institute of Technology in 1985
and his Master of Science in 1986. During his 15 years with Newcomb
& Boyd, he has developed particular expertise in the design
of mechanical systems for laboratory and research facilities. His
experience includes laboratory projects for EPA, Georgia Institute
of Technology, University of Miami, as well as numerous other Universities
across the country. His work totals more than one million square
feet and over 200 million in construction value.
