What are the best methods for improving indoor air quality in a laboratory?

1 Ventilation systems

One of the most essential components of IAQ improvement is a well-designed and maintained ventilation system that can provide adequate fresh air, remove contaminants, and control temperature and humidity. A ventilation system should include supply and exhaust fans, ducts, filters, dampers, and controls. Depending on the type and level of hazards in the laboratory, different types of ventilation systems may be required, such as general exhaust, local exhaust, fume hoods, or biosafety cabinets. You should consult with an environmental engineer or a certified industrial hygienist to determine the appropriate ventilation system for your laboratory.

3 Air filtration and purification

A third method for improving indoor air quality in a laboratory is to use air filtration and purification devices that can remove particulate matter, allergens, microbes, or odors from the indoor air. These devices can be installed in the ventilation system or used as standalone units. Some of the common types of air filtration and purification devices are high-efficiency particulate air (HEPA) filters, activated carbon filters, ultraviolet germicidal irradiation (UVGI) lamps, or photocatalytic oxidation (PCO) units. You should select the appropriate device based on the type and size of the pollutants, the airflow rate, and the energy consumption.

5 Personal protective equipment

A fifth method for improving indoor air quality in a laboratory is to wear personal protective equipment (PPE) that can protect you from exposure to harmful substances or agents in the air. PPE can include gloves, goggles, masks, respirators, or suits. You should follow the standard operating procedures, safety guidelines, and regulations for the use of PPE in the laboratory. You should also ensure that the PPE is fitted, cleaned, and stored properly. Moreover, you should monitor your health and report any symptoms or signs of illness or injury related to poor IAQ.

6 IAQ monitoring and feedback

A sixth method for improving indoor air quality in a laboratory is to conduct regular IAQ monitoring and feedback. This can help you evaluate the performance of the ventilation system, the effectiveness of the source control and air filtration and purification methods, and the compliance with the IAQ standards and criteria. You can use various instruments and methods to measure the IAQ parameters, such as temperature, humidity, carbon dioxide, VOCs, particulate matter, or biological agents. You can also collect feedback from the laboratory workers about their satisfaction, comfort, and health status. Based on the monitoring and feedback results, you can make adjustments or improvements to the IAQ methods as needed.
