USER SECTION
CHAPTER 3 – INSTALLING YOUR CABINET
3.9 PERFORMANCE VALIDATION/CERTIFICATION
After having installed the cabinet but before starting to use it, cabinet performance must be validated and
certified to be meeting factory standards. It is recommended that this validation and certification be
performed only by a
qualified technician
who is familiar with the methods and procedures for certifying
cabinets. The testing methods and equipments needed for carrying out the tests are specified on the test
report.
3.9.1 THE IMPORTANCE OF PERFOMANCE VALIDATION/CERTIFICATION
Studies have concluded that an estimated 50,000 to 70,000 workers around the world die each year from
chronic occupational diseases resulting from past exposures to toxic substances. (Source: New York
Committee for Occupational Safety and Health). Few of the salient points to take note of in this context
are:
1. A significant proportion of end-users are largely ignorant, uninformed or simply just not serious
enough about the availability of testing, safety specifications and implications of these
specifications.
2. Velocity measurement or simple airflow visualization are insufficient for deciding the safety of
cabinets.
3. Standardized testing procedures and certification help induce confidence in the tests, besides
ensuring safety of the cabinets.
3.9.2 RE-CERTIFICATION
After the initial certification, the cabinet has to be re-certified (please refer to Service Section - Chapter 1,
Sub-section 1 for more details) in the event of any of the following eventualities:
1. The cabinet has been relocated
2. The cause of airflow alarm could not be determined
3. There are doubts about the performance of the cabinet
4. Some major maintenance or servicing (filter changing, blower changing etc.) has been carried out
These eventualities apart, the cabinet must be re-certified at least once a year. In the case of cabinets
that are used for more critical applications, re-certification should be done as frequently as every 6
months.
Airflow alarm should be re-calibrated strictly subject to the conditions specified in
Service Section
Chapter 1
Section 1.1
Step 3(b).
3.9.3 DISCLAIMER
The perfomance and safety of all Esco cabinets are rigorously evaluated at our factory. However we
cannot guarantee similar levels of performance and safety after cabinet has been shipped and installed
at the user’s end because of possible wear and tear during transit. Hence we strongly recommend
frequent on-site testing.
