A below grade utilities connections vault is disclosed. The vault of the present invention comprises a concrete box with lockable, hinged lid. A floor platform lies at a distance above the bottom of the box such that utilities cables enter the box below the level of the floor. A hinged utilities wiring frame is mounted to the wall opposite the lid hinge such that the frame hinges down into the box when the vault is closed and into a vertical position for making connections. A safety barrier is formed by the lid, the wiring frame, and barrier arms which hinge between them surrounds the vault, when open. A venting system provides egress for gasses and equalization of pressure between the interior and exterior of the vault.
