Indoor Air Quality from Underwriters Lavatories
With Indoor Air Quality identified as a risk to public health, UL is advancing new testing methods, new insights and new equipment that are helping minimize its adverse effects. We are researching the effects of flame retardants on the environment and creating advances in environmental chambers that enable equipment of all sizes to be tested for chemical emissions. UL is also innovating ways to measure toxicity of both volatile organic compounds and semi-volatile organic compounds. Specifically, our work with phthalates resulted in the creation of a first-of-its-kind technique involving the collection of indoor air in specialized sorbent tubes, followed by gas chromatography mass spectrometry analysis.
