General Information

1.0 Scope of Work

The electrical infrastructure powering the two Unimount electric motors (see Pump Label 1 photo for specifications) that drive the lift station pumps presents several dangerous safety hazards to the service technicians who perform routine maintenance and monitoring as well as causing strain on the equipment they supply. The hazards identified are as follows: Incompliant Control Panel Access Clearance: The control panel and electrical shutoff must be moved out of the vault and above ground level in order to bring the system into OSHA and applicable electrical safety code compliance. Corroded Disconnect and Electrical Components: The damp environment within the vault has corroded the connections and wires in the control panel box and electrical shutoff switch. This presents several unsafe conditions and adds unnecessary wearing to the electrical motors that operate the pumps. Exposed Power Cables on Floor: The unsecured power cables that come into the vault from the floor present a tripping hazard and are exposed to damage from foot traffic. To protect the cables and technicians, the point of penetration must be secured and the cables protected in a conduit rated for a damp environment. Damaged light Fixture: The existing light fixture uses an A19 lightbulb that, due to the cramped conditions of the vault, presents a risk of being struck by a technician’s head while performing service on the lift station system. As a light source is necessary in the space to insure the safety of technicians, a low-profile, LED light fixture is needed To compound these hazards, the underground vault that they are contained in is cramped with machinery, minimal access to natural light, and often has standing water on the floor, increasing the chances of accidental electrocution. To mitigate these hazards, the exposed cable will need to be protected within waterproof conduit, the damaged light fixture will need to be replaced with a low-profile light fixture, and the electrical shutoff and control panel box will need to be moved above ground and corroded components within the control box will need to be replaced with new components.
