ASHRAE
110 - 1995 - As Installed (AI) Evaluation
The ASHRAE 110
- 1995 Method for Testing Performance of Laboratory Fume Hoods provides a quantifiable measure of containment and is recognized
as the only true measure of hood performance..Other approaches
provide qualitative measures of factors that may impact hood performance.
The new standard recognizes the benefits of a quantative measure
provided by the ASHRAE 110 methodology.
The ANSI Z9.5
Laboratory Ventilation Standard States:
"The
tracer gas containment tests shall be conducted in the ANSI/ASHRAE
110-1995 Method of Testing Performance of Laboratory Fume Hoods
or by a test recognized to be equivalent" (Source:
ANSI/AIHA Z9.5-2003 (Sec. 6.3.7))
All new fume
hoods must be evaluated on-site to achieve an acceptable ASHRAE
110 - 1995 "AI" (As Installed) rating. This is critical
for successful containment control. We will work with your team
to develop acceptable "AI" ratings for each hood, provide
the evaluation and, if necessary, a clear plan for corrective
action.
The Commissioning
Report includes all ASHRAE 110 Target Test Data vs. Measured
Performance. Concerns and Recommended Solutions, if any,
are identified during the evaluation and recommended corrective
action outlined.
This is the
recognized approach to know your chemical hoods and laboratory
design work in harmony. The "AI" rating evaluation serves
several purposes:
- It recognizes
that laboratory design factors have a significant impact on
chemcial fume hood performance
- It recognizes
that simple changes can positively impact performance
- It provides
a quantifyable benchmark measurement for each hood
- It educates
the end user of the operational limits of each hood
- It establishes
the required recording keeping system for your facility
- It educates
the end user about fume hood safety and use
We look forward
to working with you. Together we will define the desired end result
and long-term approach to Laboratory Ventilation Management that
is a good fit for your facility and budget.
