A glass blower creates designs ranging from simple to complex, using molten glass. Glass jars and vases, jewelry, art work, and figurines all may emerge from the end of a narrow tube, the skill and tools of the blower determining the final shape of the glass. The art of glass blowing itself is an old one. It was in practice in the Middle East as early as 20 BC, among the Phoenicians, when creating crude glass vessels sturdy enough to hold liquids was a great accomplishment. As practitioners became more skilled, artisans began experimenting with the creation of finely detailed and delicate blown glass that combined colors and shapes to form what amounted to works of art. Today's glass blowing techniques echo those of the past, with skilled workers using methods of glass creation that have been passed down through the generations.
Aviation Inspectors, also known as aviation safety inspectors, have been keeping the world's air transportation system safe since the development of an American airway system in the early 1920s. Although it was originally created for the U.S. Air Mail Service, it was transferred to the Federal Aviation Administration, or FAA after the Federal Aviation Act was established in 1958. Aviation inspectors are responsible for the safety of everyone who boards an airplane, as well as those remaining on the ground. Conducting preflight inspections to ensure the safety of an aircraft, these inspectors are critical in confirming that the craft is safe for flight. They have a mechanical aptitude and are able to diagnose and resolve complex problems. Often working for the FAA, they understand that following all safety guidelines is an important responsibility; therefore, an aviation inspector can mandate changes to maintenance schedules and suggest repairs as needed. Being superbly trained, they examine all the components that can affect an individual flight to ensure the safety of it's crew and passengers.
One occupation that many people are becoming increasingly interested in pursuing is in the water transportation field. In particular, the need for ship loaders is increasing at an impressive rate, and once the minimum requirements are met, ship loading can be a very rewarding occupation. A ship loader is an individual who is responsible for loading and unloading ships, maintaining the ship, and spending multiple hours, days or weeks aboard these vessels. This occupation varies quite a bit based on what kind of work is required and what types of distances are being transversed. For example, a cargo loader who specializes going up and down a local river might only be gone for a few hours while a ship loader transporting goods to from country to country may be out-of-town for days or even weeks. The work is also often seasonal due to the fact that it is quite a bit more difficult to transfer goods via waterways during winter.
Boilermakers assemble, install, and repair boilers, closed vats, and other large vessels or containers that hold liquids and gases. They perform physically demanding, dangerous work. Many must travel to worksites and live away from home for long stretches of time. Most learn their trade through a formal apprenticeship program. Candidates are more likely to get into training programs if they already have welding experience and certification.
A brickmason uses bricks to build fences, walkways, walls, patios, buildings and other structures. Brickmasons may also work with other building materials. Brickmasons are also referred to as bricklayers and just masons.
A caster works in a foundry, which is a place that is specifically designed to handle hot metals. There is a central fire area or forge that allows for the heating of the metal to make it liquid. A caster then takes the molten liquid metal and pours it into casts or molds to form metal shapes that are then sanded, grinded, and polished before being finished. A caster works with all types of metals and different molds. Some casters make their own molds or casts from different materials such as metal, wax, and sand. Metals casters work with all types of metals to produce different molded shapes.
Machining is the process of creating or changing parts that are made primarily of metal, and less frequently, of plastic or wood. It may be accomplished by cutting, grinding, drilling, lathing, polishing and other technological processes that are performed to remove excess metal and shape the part. Machinists are individuals who use machinery tools to fabricate parts according to the parameters specified in blueprints, also known as technical drawings. They generally work with materials such as steel, brass, aluminium, copper and sometimes glass, plastic or wood. Machinists have to be proficient in using various machinery equipment because the making of a part frequently requires more than one technological process and tool. Most machinery tools are electrically powered equipment, but several hand tools may also be used occasionally. Machinists are essential workers in industries or fields where replacement parts are frequently needed, especially in emergency situations when the operation of equipment depends on the availability of a specific part.
Quality control inspectors examine products and materials for defects or deviations from manufacturers’ or industry specifications. Working conditions vary by industry, establishment size, and specific duty. Most quality control inspectors work full time.
Industrial machinery mechanics maintain and repair factory equipment and other industrial machinery such as conveying systems, production machinery, and packaging equipment. Workers must follow safety precautions and use protective equipment such as hardhats, safety glasses, and hearing protectors. Most mechanics work full time. However, they may be on call or assigned to work nights or weekends. Overtime is common.
Petroleum, or oil, has been utilized since prehistoric times to provide warmth and light, in warfare, and for medicinal purposes. It is an essential resource which is used daily in most parts of the world. A petroleum pump system operator oversees petroleum refining and processing. Both the manifold and the pumping system will be controlled, governing the circulation of liquid materials through a refinery.
Tile and marble setters apply hard tile, marble, and wood tiles to walls, floors, and other surfaces. Installing tile and marble is labour intensive, and workers spend much of their time bending, kneeling, and reaching. Although the occupation is not as dangerous as some other construction trades, workers still experience a high rate of injuries and illnesses.
Gem workers, also known as precious stone workers, fulfill a pivotal role in the jewelry industry. The time-tested craftsmanship that precious stone workers laboriously produce can last for hundreds of years, placing gem workers among the most talented artists of all time. Other interchangeable job titles for gem workers include gemologist and diamond worker. Gem workers are artists of the highest caliber who carefully create jewels of everlasting beauty through the use of time-honored techniques. But increasingly, modern technology is becoming an indispensable part of a precious stone worker's repertoire. Gem workers learn their craft through traditional apprenticeship programs that educate students about the same wisdom precious stone workers have deployed for millennia. Similarly, gemology encompasses the science of precious stone formation and care. As such, gemologists closely resemble chemists who have a vast amount of knowledge of the chemical and physical properties of gemstones such as diamonds, rubies, and sapphires. This discipline differs from the field of geology, which encompasses the more general science of the history and formation of the planet.
Glaziers install glass in windows, skylights, storefronts, and display cases to create distinctive designs or reduce the need for artificial lighting. As in many other construction trades, the work is physically demanding. Glaziers risk cuts from tools and glass, and falls from ladders and scaffolding. Most work full time. About 5% were self-employed in 2010.
As the name suggests, a precious metal worker deals with precious metals such as gold, silver and platinum, and objects made from those metals. Precious metal workers are found in many industries, including jewelry, antique restoration, furniture production, mining and blacksmithing. They also perform a diverse array of tasks within each profession.
Plasterers apply coats of plaster or stucco to walls, ceilings, or partitions for functional and decorative purposes. Some workers apply ornamental plaster. The vast majority of plasterers are employed in the specialty trade contractors industry. About 53% are employed in the drywall and insulation contractors industry, while 15% are employed in the masonry contractors industry. An additional 11% are self-employed.
Heating, air conditioning, and refrigeration mechanics and installers—often referred to as HVAC technicians—work on heating, ventilation, cooling, and refrigeration systems that control the air quality in many types of buildings. They mostly work in residential homes, schools, hospitals, office buildings, or factories. Their worksites may be very hot or cold because the heating and cooling system they must repair is broken. Working in cramped spaces is common. Most work full time.
The term "rigger" originated in the days of sailing ships when sailors were responsible for raising and maintaining a complex system of sails and rigging. In modern usage, it generally refers to someone who sets equipment up and prepares it for use. According to the U.S. legal worker definition, a rigger is anyone who attaches or detaches lifting equipment to loads or lifting devices. There are a number of different categories of riggers working in several industries. In the military, riggers are responsible for maintaining and setting up things like parachutes or airdrop equipment. In the theater industry, riggers manage pieces of a stage set, moving props and changing production scenes. Riggers in the marine industry are involved with setting up the pieces of equipment necessary to keep the ship functioning: ropes, pulleys, winches, cables. Most commonly, however, jobs are found within heavy construction, often in the oil or mining industry. This type of rigger is also referred to as a Rig Technician. In the oil industry there are several levels of Rig Technicians, ranging from motorhands to derrickhands to drillers, depending on skill level and job duties. Riggers in this industry are responsible for attaching pieces of heavy machinery, connecting the parts together and anchoring pieces to fixed structures with bolts and clamps. They also control and manage all the movement of the machinery while it is operational, and then take it all apart when the job is finished.
A furniture finisher shapes, smoothens, or resmoothens damaged, worn, or used furniture or new furniture to a specified finish after which they wash the surfaces. Grinders, sanders, chisels, steel wool, pumice, and sandpaper are used for finishing, and materials used can include varnish, shellac, lacquer, stain, and/or paint. During the process, pieces of furniture are dried in rooms equipped with fans which blow warm air.
Segmental pavers, also known as segmental masons in some instances, are construction and home renovation specialists who install flat segments of brick, concrete, or other stone-like building materials. Segmental pavers work in a variety of settings, but the majority of them work in the home improvement or construction industry. Segmental masons are responsible for the planning, cutting, and laying of paving materials used to create walkways, patios, and even driveways. The discipline of segmental paving involves complex planning and designing. Working closely with clients is paramount to the success of a segmental mason's job description. Most of the time, segmental pavers work on outdoor projects such as custom-designed home patios, but occasionally segmental pavers ply their trade indoors. Cement masonry involves a multi-step process in order to create marvelous, appealing sidewalks and paths. Without the expertise of a skilled mason, these construction projects would degrade over time as topsoil shifts and settles. A large number of home improvement developers attempt to do the work of a segmental mason by themselves, but more often than not these do-it-yourself projects require repairs performed by a skilled segmental paver.
A Mine Shuttle Car Operator is part of the mine operation career area, generally working in underground mines, but sometimes in open-pit mines as well. There are many different jobs that go on inside a mine and the shuttle car operator is just one of them. Mining has a long history in most parts of the world. The shuttle car operator has been there right from the start. Many mining museums, such as the Atlas Coal Mine Historic site in Drumheller, Canada, allow visitors to get a sense of how shuttle cars were used to travel through the depths of the mine during the early days of the coal mine industry. Workers in mines face many dangers and the shuttle car operator often must travel to the farthest depths of the mine. Early mine camps were called hell's hole, not only because of the poor camp conditions, but because of the inherent danger involved in going underground. In the early days mining was hard, dirty work. It still is. Mining has always been considered a dangerous profession, and although safety has improved with new technology, mining accidents are always a concern and can happen anywhere. Car operators have been crushed between cars, had rocks or ceilings fall on them, or been electrocuted by faulty or loose cables. In 2010 the Copiapo mine in Chile provided an example of both the extremes of danger and the miracle of survival. That cave-in and subsequent near-impossible rescue of 33 miners after 69 days serves as a testament to the unique and resilient nature of the people who choose to work far below the earth. Modern mining has advanced and changed, but the hardy, brave and durable nature of the people who choose this profession has not.
