Industrial-process control - Safety of analyzer houses
IEC 61285:2015 describes the physical requirements for the safe operation of the process analyser measuring system installed in an analyser house (AH) in order to ensure its protection against fire, explosion and health hazards. This standard applies for analyser houses with inner and/or external potential explosive atmospheres and it applies to hazards caused by toxic substances or asphyxiant gases. This third edition cancels and replaces the second edition published in 2004 and constitutes a technical revision. The main changes are: - incorporation of previously issued corrigendum and - minor updates to several sections and references.
Prozessautomatisierung - Sicherheit von Analysengeräteräumen
Commande des processus industriels - Sécurité des bâtiments pour analyseurs
L'IEC 61285:2015 décrit les exigences physiques requises pour un fonctionnement sûr du système de mesure constitué par l'analyseur de processus installé dans un bâtiment pour analyseur (AH) afin d'assurer la protection contre les dangers d'incendie, d'explosion et les dangers pour la santé. La présente norme s'applique aux bâtiments pour analyseurs à atmosphères intérieures et/ou extérieures potentiellement explosives et s'applique aux dangers dus aux substances toxiques ou aux gaz asphyxiants. Cette troisième édition annule et remplace la deuxième édition parue en 2004. Elle constitue une révision technique. Les principales modifications sont: - incorporation du corrigendum paru précédemment et - mises à jour mineures de plusieurs sections et références.
Nadzor industrijskih procesov - Varnost prostorov za analiziranje (IEC 61285:2015)
Ta mednarodni standard opisuje fizikalne zahteve za varno upravljanje sistema za analiziranje, ki je nameščen v prostoru za analiziranje (AH), da je zagotovljena zaščita pred požari, eksplozijami in nevarnostmi za zdravje. Ta standard velja za prostore za analiziranje z notranjimi in/ali zunanjimi potencialno eksplozivnimi atmosferami ter tveganja, povezana s strupenimi snovmi ali zadušljivimi plini. (Glej nacionalne smernice o toksičnih nevarnostih.)
Ta standard ne zajema objektov, pri katerih so tveganje trdne snovi (prah, prašek, vlakna). Ta standard ni namenjen obravnavi vseh vprašanj funkcionalne varnosti, povezanih s prostori za analiziranje.
Točka 4 obravnava mesto prostora za analizo in povezavo znotraj območij obdelovalnega obrata.
Točka 5 obravnava zasnovo, konstrukcijo in ureditev prostora za analizo.
Standard ne obravnava delov sistema za merilne analize, nameščenih na drugih lokacijah, kot so prostori za pripravo vzorcev (SRC) ali prostori za stikalne naprave.
Točka 6 obravnava ukrepe za zmanjšanje možnosti eksplozije v prostorih za analizo z omogočanjem vzdrževanja opreme z vklopljenim napajanjem in odprtim pokrovom.
Glavna ovira pri večini tekočin je dejstvo, da je koncentracija hlapov, ki so strupeni za osebje, nižja od spodnje meje eksplozivnosti (vnetljivosti) (LEL) (glej točko 7).
Če kot primer vzamemo n-pentan, pri katerem je spodnja meja eksplozivnosti 1,4 % ali 14.000 × 10–6, je raven, ki je takoj življenjsko nevarna ali nevarna za zdravje (kar je maksimalna raven, pri kateri lahko delavec uide v 30 min brez simptomov, ki bi ovirali pobeg, ali trajnih učinkov na zdravje) samo 0,5 % ali 5.000 × 10–6.
Točka 7 obravnava ukrepe za zaščito osebja pred materiali in atmosferami prostorov za analize, ki so nevarni za zdravje.
