On appelle espace confiné toute enceinte dont la ventilation naturelle est
déficiente, dans laquelle on entre de façon occasionnelle pour procéder à son
entretien, sa réparation et/ou son nettoyage et qui est construite de telle façon
qu’une contamination dangereuse de l’atmosphère ne peut être évitée ou
éliminée par ventilation à travers des ouvertures dans l’enceinte.
DEFINITION
Sont également considérées comme espaces
confinés les enceintes dont les ouvertures
sont si éloignées ou petites qu’il est difficile
d’y entrer ou d’évacuer un travailleur qui
serait soudainement victime d’un malaise.
