The risks of indoor air quality (IAQ) for building occupants has become a complex challenging issue for facility managers and urban buildings owners.Recent research has defined pollutant source with causal links to building material and human behavior, but rare discussion about IAQ on the hair salon health risks.Hair salon works in a closed environment is often exposed for more than 10 hours daily, and how much health hazard factors are exist there? After field-testing for a hair salon, IAQ concentration data was obtained as following: 1.CO2:concentration average 1,674ppm, it is 1.67times the standard limit data.2.CO: concentration average 11.36ppm,it is 1.67times the standard limit data.3.O3: concentration average 0.147ppm, it is 2.45times the standard limit data.4.VOC: concentration average 4.54ppm, it is 7.57times the standard limit data.5.HCHO: concentration average 1,674ppm,I t is 1.67times the standard limit data.Therefore, the occupational risks of IAQ are worthy to develop for improving the safety of hair salon workplace.
