In case of an alert

Take shelter in the nearest building

Close doors, shutters and windows. If you can, seal openings and vents, turn off ventilation and air conditioning, move to a windowless room.
Even if the insulation is not total, these reflexes are the most effective. In case of an explosion, these measures will protect you from a possible toxic cloud. Do not stand next to the windows, as you could be hit by glass fragments.
