摘要： Implementations of the present disclosure relate to a blind flange and a method of installing same for isolating hazardous energy in order to provide a safe environment for workers to conduct maintenance or repair work on a facility. The blind flange has a body that defines one or more modified bores. The one or more modified bores are alignable with flanged-connection apertures of one side of a flanged connection. The one or more modified bores are configured to receive and releasably hold a connection member therein, so as to connect to only one side of the flanged connection. The modified bores allow a blind flanged-connection to be disassembled and reassemble in less time than known blind flanged-connections when one side of the blind flanged-connection is disconnected from the blind flanged-connection. Furthermore, the blind flange of the present disclosure allows the blind flange to remain connected to one side of a flanged connection while the other side is disconnected.
