Health (HDOH) considers a 15 minutes average exposure over 5 ppm to be <br />'hazardous' (http://www.hiso2index.info/assets/FinalSO2Exposurelevels.pdf). <br /> Additional air quality monitoring equipment is being installed to measure the <br />concentrations at specific locations farther from the vents. <br /> For information on SO concentrations measured daily by monitors located within <br />2 <br />communities around Hawai'i Island, see http://www.hiso2index.info/. <br />Who is monitoring the air quality in and around Leilani <br />Estates? <br /> The National Guard Civil Support Team is monitoring air quality and advising Civil <br />Defense about air quality conditions directly associated with the eruption. <br /> The HDOH is setting up SO and particle monitoring in areas around the eruption <br />2 <br />site, as they did during the Pāhoa crisis. HDOH data will become available online <br />once the monitoring equipment is up and running. <br />What should I do to stay safe? <br /> Follow mandatory evacuation orders. <br /> Consider voluntary evacuation if air quality is poor, especially if you are sensitive to <br />health effects from air pollution (such as individuals with pre-existing conditions e.g., <br />asthma, bronchitis, emphysema, lung or heart disease, infants and children, new or <br />expectant mothers, and older adults). <br />http://www.hiso2index.info/assets/FinalSO2Exposurelevels.pdf <br /> Reduce exposure to the emissions whenever possible: <br />o Limit strenuous activities <br />o Stay indoors and close all doors and windows to the outside and, if possible, <br />seal large gaps under doors or around windows <br />o Reduce indoor air pollution with an air cleaner, if you have one <br />o Restrict vog from entering your vehicle: If driving through the dense volcanic <br />plume adjacent to the erupting fissures, temporarily close your windows, and <br />turn off your fan and air conditioner to minimize air infiltration. <br />o See Vog Protection information on the Vog Dashboard for more details. <br />www.ivhhn.org/vog/vog-protection <br />What about face masks? <br /> Gas masks are not recommended: Public health officials and medical practitioners <br />do not recommend any kinds of gas masks/respirators as protection from gases for <br />the general public. This is because safe use of respirators requires correct mask <br />and/or filter cartridge selection, fit testing, physician screening, and training on <br />correct use, maintenance and storage. <br /> Sensitive groups: Children or people with pre-existing respiratory conditions should <br />be especially cautious because respirators/masks typically do not fit children and the <br /> <br />
