San Diego Fume Hood Certification

Research facilities and laboratories throughout San Diego understand that fume hoods play a vital role in maintaining a safe and effective operation. Fume hood certification and fume hood calibrations play an extremely important role in research. The team at GL Technologies provides fume hood certifications and calibration services for companies throughout the San Diego and have become a trusted provider for fume hood certifications. Chemical fume hoods should be tested and certified on an annual basis, complete ASHRAE 110 testing is recommend by GL-Tec to be performed on new fume hoods and when changes are made to existing fume hoods.

Fume Hoods - BioSafety Cabinets

When the experts at GL-Tec provide fume hood certification testing, the testing consists of an inflow velocity profile test & smoke containment & visualization tests. We recommend these tests are done annually as part of the overall chemical safety management program for the laboratory or research facility.

Fume Hood Testing and Certification is Performed in Accordance with NSF 49, which includes:

Inflow velocity testing
Downflow velocity testing
HEPA filter integrity testing
Smoke pattern testing
Site installation testing

Fume Hood Tests to be Performed

Here are a few of the tests our team will perform for San Diego fume hood certification

Airflow Velocity Testing

GL Technologies will measure the air velocity within the fume hood by checking how effective the hood's containment capabilities are, which is important to control and minimize exposure to hazardous fumes, vapors, and particles. The airflow velocity testing involves specialized instruments that measure the airflow velocity to see if it meets the required standards and guidelines for your laboratory's research. With accurate velocity testing, this will add a layer of protection for both the laboratory employees and working environment. The test measures the speed at the point air enters a fume hood's opening and a general recommendation is the hood's opening velocity (face velocity), should be between 0.3 m/s (60 fpm) and 0.5 m/s (100 fpm).

Variable Air Volume Speed & Response

The variable air volume (VAV) speed and response testing involves evaluating the performance of the fume hood's ventilation system by focusing on the airflow control mechanism. By measuring the speed and response time of the variable air volume system, our technicians can verify that the fume hood has the necessary air balance and is able to adjust the airflow to match the environmental conditions in the workspace. This testing procedure will increase laboratory safety and maintain the validity of experiments and research that is being done within the controlled laboratory environment.

Smoke Visualization Test

The smoke visualization test is performed to check how fume hood's performance in controlling hazardous fumes, vapors, and gases. During the test, non-toix smoke is released near the opening of teh fume hood, allowing our technicians to visually observe the direction and flow of the smoke. With this observation of the smoke's movement and its containment within the hood, any air leaks or inadequate airflow will be identified easily and the necessary changes can be fixed to safeguarded the health and safety of laboratory personnel.

Types of Fume Hoods for Certification

Bypass Fume Hoods

Bypass fume hoods are designed with a unique airflow configuration hat allows for a controlled flow of air with the ability to contain harmful substances. Because of a bypass mechanism, bypass fume hoods maintain a constant face velocity, even when the sash is adjusted or slightly open, preventing dangerous gases and vapors from escaping. The design of tehse fume hoods also offers energy efficiency by minimizing the air volume require for ventilation, which results in lower energy consumption.

Variable Air Volume Fume Hood

Unlike traditional fume hoods, variable air volume fume hoods incorporate sensors and controls to regulate the volume of air that is extracted based on "real-time" conditions within the hood. This type of fume hood system adjusts airflow to maintain a safe working environment by reponding to changes in the sash position and chemical fume levels. It will reduce airflow when the sash is closed or when the fume levels are low while providing lower energy consumption, lower operational costs, and improving the laboratory's air quality.

Add Air Fume Hoods

These are used as an alternative to bypass fume hoods. When there is not enough air supply available for air filtration, outside air is added through the pleneum and provide up to 70% of the hood exhaust requirements, while minimizing conditioned room air required.

As experts in fume hood certification and calibration, GL-Tec has become one of San Diego's premier fume hood certification providers proudly serving clients throughout California.
