14.1.3 Use of Energy
Energy hazards exist during the operation of components of the UST system, as well as equipment required for maintaining and/or repairing the UST system. Both use electricity as the source of power.
When not properly installed, operated and maintained, components and equipment that rely on 120/240 volts AC can cause electrical shock that can cause temporary or permanent injury, and in some instances death.
Electrical energy can also cause fires and explosions if it is not properly isolated from any ignitible vapors that might be present under normal operating conditions of the UST system.
The requirements for properly isolating electrical energy from components of the UST system and equipment used for maintaining and/or repairing the UST system are defined by several nationally recognized standards and codes of practice. These include NFPA 30 and The National Electrical Code.
