Laboratories are a place for trained professionals, who understand the hazards that could occur if proper guidelines are not followed.

Taking into consideration the risks that come with working in a lab, the design and construction of chemistry laboratories should be such that it incorporates all the safety measures mentioned in the guidelines by the respective authorities.

One of the most crucial aspects to be considered in the design of a Chemistry Lab is the laboratory ventilation system.

There are various costs related to fume hoods that are not considered, but add up to a substantial amount at the end of the year.

1. Fume Hoods with High Performance: Depending on their face velocity and other industry standards, a high performance fume hood should be installed in a lab. These are capable of protecting the personnel from toxic fumes that are released due to various activities. The energy efficiency is also higher for such systems. Either by consulting an expert or calculating the volumetric flow (with the CFM), a clear idea can be established as to the capacity of the fume hood.

2. Using a VAV (Variable Air Volume) System: Depending on the position of the sash, the VAV system can adjust the supply and exhaust air by using the inbuilt sensors. At the end of the day, or when the working personnel have left, the system begins an automatic shutdown starting with the sash, which initiates the closing of the valve of the fume hood exhaust. This drastically decreases the tempered air that would have been exhausted otherwise. Along with this, the amount of air that enters the lab is also reduced. With the VAV system, the expenses due to laboratory ventilation are reduced.

3. Installing Automatic Sash: By calculating the motion and presence of a human in front of the hood, the automatic sash positioning system will adjust the sash in the required manner. A VAV system shall benefit greatly with an automated sash, considering the energy savings the VAV is installed for. When the height of the sash is adjusted, so does the airflow which ends up saving energy used to run the system and keep the lab safe.

In order to remove the toxicity from the air in the labs, it is a must that an efficient laboratory ventilation system is provided. And even then, timely checks should be performed to ensure that no toxicity is escaping into the lab.

Vanguard fume hoods are of international quality and maintain safety standards. They provide their clients with well-designed Lab Ventilation Systems (LVS) that deliver the expected level of safety.
