Collective protection measures - methods to ensure clean air

Abstract

The review article deals with the current issue of collective protection, including collective protection against contamination. The division of collective protection means by purpose and basic equipment for use under conditions of contamination is presented. Based on NATO documents, functional and operational recommendations were formulated. Methods of protecting facilities from the penetration of contaminated air by sealing, dilution in vestibules and the creation of positive pressure support were characterized. Methods of ventilating facilities with respect to changing the composition and properties of air in confined spaces are presented, including determining the necessary amount of air to ventilate rooms to remove excess CO2, water vapor, heat and oxygen deficiency. Methods of supplying clean air to the facility by means of air filtration and regeneration are characterized.
