The Use of Tracer Gases in Measuring Ventilation Rates

Often, ventilation rates in residences, offices or commercial establishments must be determined.  If ventilation rates are too low, complaints about indoor air quality may arise.  If ventilation rates are too great, heating and cooling costs may rise.  Ventilation can be controlled by using heating ventilation and air condition (HVAC) equipment that allows fresh outside air into occupied spaces after being adequately conditioned.  The inflow of uncontrolled air, such as through poorly insulated gaps around windows and doors can affect the quality and amount of air exchange.  Using tracer gases can help to identify ventilation rates, reduce energy costs, and ensure occupant comfort.  Tracer gases can also be used to identify the rate of decay of certain environmental contaminants.

This prompted New York State (NYS) and New York City (NYC) to enact emergency regulations in 2015 that focused on cooling tower maintenance as the most effective approach to managing Legionella exposure risk.

Sampling and Analytical Considerations for Beryllium

Beryllium (Be) is a strong, light metal useful in electronics, aerospace, and for windows in radiation detection equipment. From a worker health perspective exposure to beryllium is linked to beryllium sensitization and Chronic Beryllium Disease (CBD), which is incurable, debilitating, and potentially fatal.
