Security and resilience - Guidelines for hardened protective shelters (ISO 22359:2024)

This document provides guidelines for the design, use and maintenance of hardened protective shelters (hereafter referred to as “shelters”). It specifies guidance on the layout, structures, equipment and actions related to a shelter.
This document is intended for organizations or individuals responsible for or involved in decision-making, planning, implementation, administration, use or upkeep of shelters, such as local, regional and national governments, civil protection agencies, first responders and businesses such as designers, constructers and equipment suppliers.
This document does not cover the minimum requirements or exact specifications for the properties of or actions related to a shelter; nor does it cover rapidly erected temporary shelters, such as lightweight canvas weather shelters, other tarp tent shelters, or metal and container shelters. Military shelters are subject to additional requirements which are outside the scope of this document.

Sécurité et résilience - Lignes directrices relatives aux abris durcis (ISO 22359:2024)

Le présent document fournit des lignes directrices pour la conception, l’utilisation et l’entretien des abris durcis (ci-après dénommés « abris »). Il fournit des recommandations concernant l’aménagement, les structures, l’équipement et les actions liées à un abri.
Le présent document est destiné aux organisations ou aux personnes responsables ou impliquées dans la prise de décision, la planification, la mise en œuvre, l’administration, l’utilisation ou l’entretien des abris, telles que les gouvernements locaux, régionaux et nationaux, les agences de sécurité civile, les premiers intervenants et les entreprises telles que les concepteurs, les constructeurs et les fournisseurs d’équipement.
Le présent document ne couvre pas les exigences minimales ou les spécifications exactes des propriétés ou des actions liées à un abri. Il ne couvre pas non plus les abris temporaires construits rapidement, tels que les abris légers en toile contre les intempéries, les autres abris en toile de tente ou les abris en métal et sous forme de conteneur. Les abris militaires sont soumis à des exigences supplémentaires qui n’entrent pas dans le domaine d’application du présent document.
