If you have asthma

If vog is expected to enter your community, the wisest strategy is to relocate to a safer location until the air is free of vog.  Because the winds are so difficult to forecast with accuracy, it’s also advisable to have both current medications as well as a gas/particulate mask available to you at all times.  Even when evacuating, it’s possible that you will have to pass through higher concentrations of vog than are present in your home community so you should carry these items with you as you evacuate.
