Information on vog for schools

Schools need to be prepared to address vog-related exposures and take actions appropriate to protect children and staff.  Children or staff with pre-existing respiratory or heart disease are at higher risk for potential health effects from vog. Schools closer to the volcanic vent(s) potentially could be exposed to elevated levels of both SO2 gas and fine particles (PM2.5), while schools further away from the source vent(s), such as in West Hawaiʻi, may only have to address fine particle exposures. Ashfall events may also affect schools downwind of the source. Exposures to these air contaminants are variable, depending on the amount and type of volcanic emissions on any day, the wind direction and wind speed, and the distance from the source vent(s).

Note that most school buildings on Hawaiʻi Island are old and without air-conditioning, so are not built very ‘tight’ and, therefore, do not prevent infiltration of outdoor air (when doors and windows are closed) for long periods of time. To respond to this situation, schools have established designated spaces to use as ‘sensitive’ rooms, with greater levels of protection for kids or staff who may need it during temporary increases in vog concentrations. There are air monitoring stations at a number of  schools, while others need to check readings from the nearest monitoring location available, or perhaps utilize hand-held monitoring devices if those are available. The Hawaii Department of Education (HDOE) school action plans (below) for SO2, fine particles (PM2.5), and ashfall events provide recommended actions tied to the specific, color-coded, air concentrations (SO2 and PM2.5),  or accumulation amount of ash. As concentrations (or accumulation) increase, more protective actions need to be taken.


School action plans for SO2, PM2.5 and ash

The Hawaii State Department of Health (HDOH), HDOE school representatives, and nursing professionals have developed the following action plans for schools:

1. Schools sulfur dioxide (SO2) action plan

Recommended actions/activities at specific SO2 concentrations/advisory levels




2. Schools particulate matter (PM2.5) action plan

Recommended actions/activities at specific PM2.5 concentrations/advisory levels




3. Schools volcanic ashfall action plan

Recommended actions/activities at various ash accumulation levels




Please note: the above action plans state that affected individuals will be evaluated by SHA using sections of the SHA Manual. SHA are School Health Aides (HDOE employees at public schools).
Manual section 3-3-9 Asthma, wheezing, difficult breathing
Manual section 3-3-28 Eye problems (injury)
Manual section 3-3-29 Eye problems (particle in eye)
