Maids and Housekeeping Cleaners

Maids and housekeeping cleaners perform general cleaning tasks, including making beds and vacuuming halls, in private homes and commercial establishments.

Maids and housekeeping cleaners typically do the following:

  • Clean rooms, hallways, and other living or work areas
  • Change sheets and towels; make beds; wash, fold, and iron clothes
  • Empty wastebaskets and take trash to disposal areas
  • Replenish supplies, such as soap and toilet paper
  • Dust and polish furniture and equipment
  • Sweep, wax, or polish floors using brooms, mops, or other floor-cleaning equipment
  • Vacuum rugs, carpets, and upholstered furniture
  • Clean or polish windows, walls, and woodwork
  • Lift and move lightweight objects and equipment

Maids and housekeeping cleaners do light cleaning tasks in homes and commercial establishments, such as hotels, restaurants, hospitals, and nursing homes.

In addition to keeping these places clean and neat, maids who work in private homes also may prepare meals, polish silver, and clean ovens, refrigerators, and sometimes windows. Some also shop for groceries, pick up and drop off dry cleaning, and do other errands.

Those who work in hotels, hospitals, and other commercial establishments are responsible for cleaning and maintaining the premises. They may also share other duties. For example, housekeeping cleaners in hotels may deliver ironing boards, cribs, and rollaway beds to guests' rooms. In hospitals, workers may have to wash bed frames and disinfect and sanitize equipment with germicides.


Power Plant Operators, Distributors, and Dispatchers

Power plant operators, dispatchers, and distributors control the systems that generate and distribute electric power.

Power plant operators, distributors, and dispatchers typically do the following:

  • Control power-generating equipment, such as boilers, turbines, generators, and reactors
  • Read charts, meters, and gauges to monitor voltage and electricity flows
  • Check equipment and indicators to detect evidence of operating problems
  • Adjust controls to regulate the flow of power
  • Start or stop generators, turbines, and other equipment as necessary

Electricity is one of our nation's most vital resources. Power plant operators, distributors, and dispatchers control power plants and the flow of electricity from plants to substations, which distribute electricity to businesses, homes, and factories. Electricity is generated from many sources, including coal, gas, nuclear energy, hydroelectric energy (from water sources), and wind and solar power.

The following are types of power plant operators, distributors, and dispatchers:

Nuclear power reactor operators control nuclear reactors. They adjust control rods, which affect how much electricity a reactor generates. They monitor reactors, turbines, generators, and cooling systems, adjusting controls as necessary. Operators also start and stop equipment and record the data. They may need to respond to abnormalities, determine the cause, and take corrective action.

Power distributors and dispatchers, also known as systems operators, control the flow of electricity as it travels from generating stations to substations and users over a network of transmission and distribution lines. They prepare and issue switching orders to route electrical currents around areas that need maintenance or repair. Distributors and dispatchers also monitor and operate current converters, voltage transformers, and circuit breakers. They must detect and respond to emergencies, such as transformer or transmission line failures.

Power plant operators control, operate, and maintain machinery to generate electric power. They use control boards to distribute power among generators and regulate the output from several generators. They regulate the flow of power between generating stations and substations, and they monitor instruments to maintain voltage and electricity flows from the plant.


Electrical and Electronics Engineers

Electrical engineers design, develop, test, and supervise the manufacturing of electrical equipment such as electric motors, radar and navigation systems, communications systems, or power generation equipment. Electrical engineers also design the electrical systems of automobiles and aircraft.

Electronics engineers design and develop electronic equipment such as broadcast and communications systems, from portable music players to global positioning systems (GPS). Many also work in areas closely related to computer hardware.

Electrical engineers typically do the following:

  • Design new ways to use electrical power to develop or improve products
  • Do detailed calculations to compute manufacturing, construction, and installation standards and specifications
  • Direct manufacturing, installing, and testing to ensure that the product as built meets specifications and codes
  • Investigate complaints from customers or the public, evaluate problems, and recommend solutions
  • Work with project managers on production efforts to ensure projects are completed satisfactorily, on time, and within budget

Electronics engineers typically do the following:

  • Design electronic components, software, products, or systems for commercial, industrial, medical, military, or scientific applications
  • Analyze electrical system requirements, capacity, cost, and customer needs and then develop a system plan
  • Develop maintenance and testing procedures for electronic components and equipment
  • Evaluate systems and recommend repair or design modifications
  • Inspect electronic equipment, instruments, and systems to make sure they meet safety standards and applicable regulations
  • Plan and develop applications and modifications for electronic properties used in parts and systems to improve technical performance

Electronics engineers who work for the federal government research, develop, and evaluate electronic devices used in diverse technologies, such as aviation, computing, transportation, and manufacturing. They work on federal electronic devices and systems, including satellites, flight systems, radar and sonar systems, and communications systems.

The work of electrical engineers and electronics engineers is often similar. Both use engineering and design software and equipment to do engineering tasks. Both types of engineers must also work with other engineers to discuss existing products and possibilities for engineering projects.

Engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. For more information about this occupation, see the profile on computer hardware engineers.


Mechanical Engineering Technicians

Mechanical engineering technicians help mechanical engineers design, develop, test, and manufacture industrial machinery, consumer products, and other equipment. They may make sketches and rough layouts, record and analyze data, make calculations and estimates, and report their findings.

Mechanical engineering technicians typically do the following:

  • Evaluate drawing designs for new or changed tools by measuring dimensions on the drawing and comparing them with the original specifications
  • Prepare layouts and drawings of parts to be made and the process for putting them together
  • Discuss changes with coworkers--for example, in the design of the part, in the way it will be made and put together, and in the techniques and process they will use
  • Review instructions and blueprints for the project to ensure the test specifications, procedures, and objectives
  • Plan, make, and put together new or changed mechanical parts for products, such as industrial machinery or equipment
  • Set up and conduct tests of complete units and of parts as they would really be used, as a way to investigate proposals for improving equipment performance
  • Record test procedures and results, numerical and graphical data, and recommendations for changes in product or test methods
  • Analyze test results in regarding design specifications and test objectives

Mechanical engineering technicians also estimate labor costs, equipment life, and plant space. Some test and inspect machines and equipment or work with engineers to eliminate production problems. They may assist in testing products by, for example, setting up instrumentation for vehicle crash tests.


Construction Laborers and Helpers

Construction laborers and helpers do many basic tasks that require physical labor on construction sites.

Construction laborers and helpers typically do the following:

  • Clean and prepare construction sites by removing debris and possible hazards
  • Load or unload building materials to be used in construction
  • Build or take apart bracing, barricades, forms (molds that determine the shape of concrete), scaffolding, and temporary structures
  • Dig trenches, backfill holes, or compact earth to prepare for construction
  • Operate or tend equipment and machines used in construction, such as concrete mixers
  • Help other craftworkers with their duties
  • Follow construction plans and instructions from the people they are working for

Construction laborers and helpers work on almost all construction sites, doing a wide range of tasks from the very easy to the extremely difficult and hazardous. Although many of the tasks they do require some training and experience, most jobs usually require little skill and can be learned quickly. 

The following are occupational specialties:

Construction laborers do a variety of construction-related activities during all phases of construction. Although most laborers are generalists--such as those who install barricades, cones, and markers to control traffic patterns--many others specialize. For example, those who operate the machines and equipment that lay concrete or asphalt on roads are more likely to specialize in those areas.

Most construction laborers work in the following areas:

  • Building homes and businesses
  • Tearing down buildings
  • Removing hazardous materials
  • Building highways and roads
  • Digging tunnels and mine shafts

Construction laborers use a variety of tools and equipment. Some tools are simple, such as brooms and shovels; other equipment is more sophisticated, such as pavement breakers, jackhammers, earth tampers, and surveying equipment.

With special training, laborers may help transport and use explosives or run hydraulic boring machines to dig out tunnels. They may learn to use laser beam equipment to place pipes and use computers to control robotic pipe cutters. They may become certified to remove asbestos, lead, or chemicals.

Helpers assist construction craftworkers, such as electricians and carpenters, with a variety of basic tasks. They may carry tools and materials or help set up equipment. For example, many helpers work with cement masons to move and set forms. Many other helpers assist with taking apart equipment, cleaning up sites, and disposing of waste, as well as helping with any other needs of craftworkers.

Many construction trades have helpers who assist craftworkers. The following are examples of trades that have associated helpers:

  • Brickmasons, blockmasons, stonemasons, and tile and marble setters
  • Carpenters
  • Electricians
  • Painters, paperhangers, plasterers, and stucco masons
  • Pipelayers, plumbers, pipefitters, and steamfitters
  • Roofers
