rearrange, or remove |
| switching and dialing
equipment used in central offices. Service or repair telephones and other
communication |
| equipment on customers'
property. May install equipment in new locations or install wiring and
telephone jacks in |
| buildings under
construction. |

|
| Electrical Power-Line
Installers and Repairers install or repair cables or wires |
| used in electrical
power or distribution systems. May erect poles and light or heavy duty
transmission towers. |
| Excludes Electrical and
Electronics Repairers, Powerhouse, Substation, and Relay. |
|
|
|
|
| Auxiliary equipment
operators work throughout a power plant, operating and monitoring valves,
switches, and gauges. |
| Nuclear Power Reactor
Operators control nuclear reactors. The Nuclear Regulatory Commission
(NRC) licenses |
| operators of nuclear
power plants. Reactor operators are authorized to control equipment that
affects the power of |
| the reactor in a
nuclear power plant. In addition, an NRC-licensed senior reactor operator
must be on duty during |
| each shift to act as
the plant supervisor and supervise the operation of all controls in the
control room. |
|
|
|
|
| Nuclear Technicians
assist scientists in both laboratory and production activities by
performing technical tasks |
| involving nuclear
physics, primarily in operation, maintenance, production, and quality
control support activities. |
|
|
|
|
| Power distributors and
dispatchers, also called load dispatchers or systems operators, control
the flow of |
| electricity through
transmission lines to industrial plants and substations that supply
residential electric needs. |
| They monitor and
operate current converters, voltage transformers, and circuit breakers.
Dispatchers also monitor |
| other distribution
equipment and record readings at a pilot boardùa map of the transmission
grid system showing the |
| status of transmission
circuits and connections with substations and industrial
plants. |
|
|
|
|
| Power plant operators
control and monitor boilers, turbines, generators, and auxiliary equipment
in |
| power-generating
plants. Operators distribute power demands among generators, combine the
current from several |
| generators, and monitor
instruments to maintain voltage and regulate electricity flows from the
plant. When power |
| requirements change,
these workers start or stop generators and connect or disconnect them from
circuits. They |
| often use computers to
keep records of switching operations and loads on generators, lines, and
transformers. |
| Operators also may use
computers to prepare reports of unusual incidents, malfunctioning
equipment, or maintenance |
| performed during their
shift. |
|
|
|
|
| Electrical and
Electronics Repairers, Powerhouse, Substation, and Relay
inspect, |
| test, repair, or
maintain electrical equipment in generating stations, substations, and
in-service relays. |

|
|
| Electric Meter
Installers and Repairers install electric meters on customers' premises or
on pole. Test meters and |
| perform necessary
repairs. Turn current on/off by connecting/disconnecting service
drop. |
|
|
|
|
| Gas Compressor
Operators operate steam or internal combustion engines to transmit,
compress, or recover gases, such |
| as butane, nitrogen,
hydrogen, and natural gas, in various production processes. |
|
|
|
|
| Gas Compressor and Gas
Pumping Station Operators operate steam, gas, electric motor, or internal
combustion engine |
| driven compressors.
Transmit, compress, or recover gases, such as butane, nitrogen, hydrogen,
and natural gas. |
|
|
|
|
| Gas Plant
Operatorsdistribute or process gas for utility companies and others
by |
| controlling compressors
to maintain specified pressures on main pipelines. They adjust
temperature, pressure, |
| vacuum, level, flow
rate, and/or transfer of gas to maintain processes at required levels or
to correct problems. |
|
|
|
|
| Gas Pumping Station
Operators control the operation of steam, gas, or electric-motor-driven
compressor to maintain |
| specified pressures on
high and low-pressure mains dispensing gas from gasholders. |
|
|
|
|
| Control and Valve
Installers and Repairers, Except Mechanical Door install, repair, and
maintain mechanical |
| regulating and
controlling devices, such as electric meters, gas regulators, thermostats,
safety and flow valves, |
| and other mechanical
governors. |
|
|
|
|
| Meter readers read
electric, gas, water, or steam consumption meters and record the volume
used. They serve both |
| residential and
commercial consumers, either walking or driving along the designated
route. Their duties include |
| inspecting the meters
and their connections for any defects or damage, supplying repair and
maintenance workers |
| with the necessary
information to fix damaged meters, keeping track of the average usage, and
recording reasons for |
| any extreme
fluctuations in volume. |
| |
|
|
| Water treatment
plant and system operators treat water so that it is safe to drink.
Liquid waste treatment plant |
| and system
operators, also known as wastewater treatment plant and system
operators, remove harmful pollutants from |
| domestic and
industrial liquid waste so that it is safe to return to the
environment. Water is pumped from wells, |
| rivers, streams,
and reservoirs to water treatment plants, where it is treated and
distributed to customers. Liquid |
| waste travels
through customersÆ sewer pipes to liquid waste treatment plants,
where it is either treated and |
| returned to
streams, rivers, and oceans or reused for irrigation and
landscaping. Operators in both types of plants |
| control equipment
and processes that remove or destroy harmful materials, chemical
compounds, and microorganisms |
| from the
water. |
