Sistemi, namenjeni kar najhitrejšemu izključevanju posebne opreme ob razvijajočih se eksplozijah z uporabo ustreznih naprav, morajo biti projektirani in načrtovani tako, da so odporni proti prebojnemu vžigu in da ohranijo svojo mehansko trdnost v delovnih razmerah.
Decoupling systems intended to disconnect specific equipment as swiftly as possible in the event of incipient explosions by means of appropriate devices must be planned and designed so as to remain proof against the transmission of internal ignition and to retain their mechanical strength under operating conditions.
