Abstract

There are situations in which human health is at risk from inhalation of hazardous substances and particles (viral epidemics, biological weapons, chlorine leaks, nuclear accidents, asbestos removal, quarrying). In response to these scenarios, emphasis is placed on respiratory protection and minimising exposure to these substances and particles. One of the most commonly used respiratory protective devices is respirators. However, respiratory protection for children is not addressed by any manufacturing or testing technical standard. There are children's respirators on the market that are rather scaled-down versions of adult respirators. Yet there is a very significant difference between these target groups in terms of body morphology and respiratory physiology. Therefore, there is an urgent need to develop a standard that precisely defines the requirements for respirators intended for children to ensure effective protection of their airways. Based on the research carried out, four groups of sizes of children's respirators were proposed using existing standards, taking into account the requirements of the child user.
