Drywall and ceiling tile installers hang wallboards to walls and ceilings inside buildings. Tapers prepare the wallboards for painting, using tape and other materials. Many workers do both installing and taping.

Drywall installers typically do the following:

• Review design plans to minimize the number of cuts and waste of wallboard
• Measure the location of electrical outlets, plumbing, windows, and vents
• Cut drywall to the right size, using utility knives and power saws
• Fasten drywall panels to interior wall studs, using nails or screws
• Trim and smooth rough edges so boards join evenly

Ceiling tile installers typically do the following:

• Measure according to blueprints or drawings
• Nail or screw supports
• Put tiles or sheets of shock-absorbing materials on ceilings  
• Keep the tile in place with cement adhesive, nails, or screws

Tapers typically do the following:

• Prepare wall surface (wallboard) by patching nail holes
• Apply tape and use sealing compound to cover joints between wallboards
• Apply additional coats of sealing compound to create an even surface
• Sand all joints and holes to a smooth, seamless finish

Installers are also called framers or hangers. Tapers are also called finishers. Ceiling tile installers are sometimes called acoustical carpenters because they work with tiles that block sound.

Once wallboards are hung, workers use increasingly wider trowels to spread multiple coats of spackle over cracks, indentations, and any remaining imperfections. Some workers may use a mechanical applicator, a tool that spreads sealing compound on the wall joint while dispensing and setting tape at the same time.

To work on ceilings, drywall and ceiling tile installers and tapers may use mechanical lifts or stand on stilts, ladders, or scaffolds.

Heating, air conditioning, and refrigeration mechanics and installers--often referred to as HVACR technicians--work on heating, ventilation, cooling, and refrigeration systems that control the air quality in many types of buildings.

Heating, air conditioning, and refrigeration mechanics and installers typically do the following:

• Travel to worksites
• Follow blueprints or other design specifications to install or repair HVACR systems
• Connect systems to fuel and water supply lines, air ducts, and other components
• Install electrical wiring and controls and test for proper operation
• Inspect and maintain customers' HVACR systems
• Test individual components to determine necessary repairs
• Repair or replace worn or defective parts

Heating and air conditioning systems control the temperature, humidity, and overall air quality in homes, businesses, and other buildings. By providing a climate controlled environment, refrigeration systems make it possible to store and transport food, medicine, and other perishable items.

Although trained to do all three, HVACR technicians sometimes work strictly with heating, air conditioning, or refrigeration systems. They also may specialize in certain types of HVACR equipment, such as water-based heating systems, solar panels, or commercial refrigeration.

Depending on the task, HVACR technicians use many different tools. For example, they often use screwdrivers, wrenches, pipe cutters and other basic handtools when installing systems. To test or install complex system components, technicians may use more sophisticated tools, such as carbon monoxide testers, voltmeters, combustion analyzers, and acetylene torches.

When working on air conditioning and refrigeration systems, technicians must follow government regulations regarding the conservation, recovery, and recycling of refrigerants. This often entails proper handling and disposal of fluids.  

Some HVACR technicians sell service contracts to their clients, providing regular maintenance of heating and cooling systems.

Other craft workers sometimes help install or repair cooling and heating systems. For example, on a large air conditioning installation job, especially one in which workers are covered by union contracts, ductwork might be done by sheet metal workers and duct installers, or electrical work by electricians. In addition, home appliance repairers usually service window air conditioners and household refrigerators. For more information on these occupations, see the profiles on sheet metal workers, electricians, or home appliance repairers.

Insulation workers install and replace the materials used to insulate buildings and their mechanical systems to help control and maintain temperature. Workers are often referred to as insulators.

Insulation workers typically do the following:

• Remove old insulation and dispose of it properly
• Read blueprints and specifications to determine job requirements
• Determine the amounts and types of insulation needed
• Measure and cut insulation to fit into walls and around pipes
• Fasten insulation in place with staples, tape, or screws
• Use compressors to spray insulation into some spaces
• Install plastic barriers to protect insulation from moisture
• Follow safety guidelines

Properly insulated buildings save energy by keeping heat in during the winter and out in the summer. Insulated vats, vessels, boilers, steam pipes, and hot-water pipes also prevent the wasteful loss of heat or cold and prevent burns. Insulation also helps reduce noise that passes through walls and ceilings.

When renovating old buildings, insulators often must remove the old insulation. In the past, asbestos--now known to cause cancer--was used extensively to insulate walls, ceilings, pipes, and industrial equipment. Because of this danger, specially trained workers are required to remove asbestos before insulation workers can install the new insulating materials. For more information, see the profile on hazardous materials removal workers.

Insulation workers use common hand tools, such as knives and scissors. They also may use a variety of power tools including power saws to cut insulating materials, welders to secure clamps, and staple guns to fasten insulation to walls. Some insulators use compressors to spray insulation onto walls.

Workers sometimes wrap a cover of aluminum, sheet metal, or vapor barrier (plastic sheeting) over the insulation. Doing so protects the insulation by keeping moisture out. 

The following are examples of insulation workers:

Floor, ceiling, and wall insulators install insulation in attics, floors, and behind walls in homes and other buildings. Most of these workers unroll, cut, fit, and staple batts of fiberglass insulation between wall studs and ceiling joists. Some workers, however, spray foam insulation with a compressor hose into the space being filled.

Mechanical insulators apply insulation to pipes or ductwork in businesses, factories, and many other types of buildings. When insulating a steam pipe, for example, the temperature, thickness, and diameter of the pipe are all factors that determine the type of insulation to be used.

Pest control workers control, manage, or remove unwanted creatures, such as roaches, rats, ants, termites, and bedbugs, that infest buildings and surrounding areas. 

Pest control workers typically do the following:

• Inspect buildings and premises for signs of pests or infestation
• Determine the type of treatment needed to eliminate pests
• Measure the dimensions of the area needing treatment
• Estimate the cost of their services
• Set bait and traps to remove or kill pests
• Spray or dust pesticides into rooms
• Design and carry out pest management plans
• Drive trucks equipped with power spraying equipment
• Create barriers to prevent pests from entering a building

Unwanted pests that infest buildings or surrounding areas can pose serious risks to the health and safety of occupants. Pest control workers control, manage, or remove these creatures from homes, apartments, offices, and other structures to protect people and to maintain buildings' structural integrity.

To design and carry out integrated pest management (IPM) plans, pest control workers must know the identity and biology of a wide range of pests. They must also know the best ways to control or remove the pests.

Pest control workers' position titles and job duties often vary by state. The following are types of pest control workers:

Pest control technicians identify potential pest problems, conduct inspections, and design control strategies. They work directly with customers and, as entry-level workers, use only a limited range of pesticides.

Applicators use a wide range of pesticides and may specialize in a particular area of pest control:

• Termite control technicians use chemicals and modify structures to eliminate termites and prevent future infestations. Some also repair structural damage caused by termites and build barriers to separate pests from their source of food.
• Fumigators use poisonous gases, called fumigants, to treat serious infestations. Fumigators seal infested buildings before using hoses to fill the structure with fumigants. Warning signs are posted to keep people from going into fumigated buildings, and fumigators monitor buildings closely to detect and stop leaks.

Animal care and service workers care for the needs of animals. They feed, water, groom, bathe, and exercise pets and other nonfarm animals. Job tasks vary by position and place of work.

Animal care and service workers typically do the following:

• Feed and give water to animals
• Clean equipment and the living spaces of animals
• Monitor animals and record information such as their diet, physical condition, and behavior
• Examine animals for signs of illness or injury
• Exercise animals
• Bathe animals, trim nails, clip hair, and attend to other grooming needs
• Train animals to obey or to do specific behaviors

Animal care and service workers train, feed, groom, and exercise animals. They also clean, disinfect, and repair the animals' cages. They play with the animals, provide companionship, and observe behavioral changes that could indicate illness or injury.

Boarding kennels, pet stores, animal shelters, rescue leagues, veterinary hospitals and clinics, stables, laboratories, aquariums and natural aquatic habitats, and zoological parks all house animals and employ animal care and service workers. 

Nonfarm animal caretakers typically work with cats and dogs in animal shelters or rescue leagues. All caretakers attend to the basic needs of animals, but experienced caretakers may have more responsibilities, such as helping to vaccinate or euthanize animals under the direction of a veterinarian. Caretakers also may have administrative duties, such as keeping records on the animals, answering questions from the public, educating visitors about pet health, or screening people who want to adopt an animal. 

Animal trainers train animals for riding, security, performance, obedience, or assisting people with disabilities. They familiarize animals with human voices and contact, and they teach animals to respond to commands. Most animal trainers work with dogs and horses, but some work with marine mammals, such as dolphins. Trainers teach a variety of skills. For example, some may train dogs to guide people with disabilities; others teach animals to cooperate with veterinarians or train animals for a competition or show. 

The following are types of animal care and service workers:

Groomers specialize in maintaining a pet's appearance. Groomers may operate their own business, work in a grooming salon, or, increasingly, run their own mobile grooming service that travels to clients' homes. Demand for mobile grooming services is growing because these services are convenient for pet owners, allowing the pet to stay in its familiar environment.

Some groomers are employed by kennels, veterinary clinics, or pet supply stores, where they groom mostly dogs, but some cats, too. In addition to cutting, trimming, and styling the pet's fur, groomers clip nails, clean ears, and bathe pets. Some groomers also schedule appointments, sell products to pet owners, and identify problems that may require veterinary attention.

Grooms care for horses. Grooms work at stables and are responsible for feeding, grooming, and exercising these animals. They saddle and unsaddle horses, give them rubdowns, and cool them off after a ride. In addition, they clean out stalls, polish saddles, and organize the tack room where they keep harnesses, saddles, and bridles. They take care of food and supplies for the horses. Experienced grooms also may help train horses. 

Keepers are animal care and service workers who work in zoos. They plan the animals' diets, feed them, and monitor their eating patterns. They also clean the animals' enclosures, monitor their behavior, and watch for signs of illness or injury. Depending on the size of the zoo, they may work with either a broad or a limited group of animals. They may help raise young animals, and they often spend time answering questions from the public. 

Kennel attendants care for pets while their owners are working or are traveling. Basic attendant duties include cleaning cages and dog runs, and feeding, exercising, and playing with animals. Experienced attendants also may provide basic healthcare, bathe animals, and attend to other basic grooming needs. 

Pet sitters look after animals while the owner is away. They go to the pet owner's home, allowing the pet to stay in its familiar surroundings and follow its routine. Most pet sitters feed, walk, and play with pets daily. More experienced pet sitters also may bathe, groom, or train pets. Most watch over dogs, but a few take care of cats.
