The first line of defence is to wear a respirator. Alternatively, one can cover the whole face with a wet cloth, wet bandana or a mask; along with tight glasses e.g. swimming goggles. One should wear long clothing, the aim being to cover the skin as much as possible. Do not wear contact lenses and make-up. One should try to shift to an upright or standing position as the particles of<unk>  settle down.
