NOTE Nitrogen is, today, the most suitable gas to be used for oxygen reduction. For other gases, this document can be used as a reference.
- explosion prevention systems, in case of chemicals or materials containing their own supply of oxygen, such as cellulose nitrate;
- fire extinguishing systems using gaseous extinguishing agents;
- inertization of portable containers;
- systems in which oxygen levels are reduced for reasons other than fire prevention (e.g. steel processing in the presence of inert gas to avoid the formation of oxide film);
- inerting required during repair work on systems or equipment (e.g. welding) in order to eliminate the risk of fire or explosion.
In addition to the conditions for the actual oxygen reduction system and its individual components, this document also covers certain structural specifications for the protected area.
The space protected by an oxygen reduction system is a controlled and continuously monitored indoor climate for extended occupation. This document does not cover unventilated confined spaces that can contain hazardous gases.
L'amosfera ipossica, influisce sulla permanenza di un individuo, in particolare essa è dovuta a:
- percentuale di ossigeno residuo in ambiente;
- tempo di esposizione;
- sforzo legato all’azione da compiere;
- caratteristiche fisiche del soggetto;
- caratteristiche del locale (segnalazioni e vie d’esodo).
E' necessario garantire determinate misure di sicurezza in atmosfera sotto-ossigenata.
Il Documento al link sottostante tratta tali Sistemi in relazione alla 1a norma ISO in merito: ISO 20338:2019
