Abstract
A civilian anti-terrorist attack gas mask used as an emergency measure to remove hazardous air pollutants present in air drawn from an ambient atmosphere to provide a person with suitably breathable air is provided in the form of a cap fitted over the person's head and carrying a hood draped over the person's head to establish a chamber contiguous with the person's face, the gas mask including an impeller assembly placed in a peak on the cap for drawing air from the ambient atmosphere through an adsorption element and a filter element to circulate fresh breathable air through the chamber, the impeller assembly maintaining an air pressure in the chamber raised above the ambient air pressure.
