Scientific applications in the biological and agricultural industries have enabled our country to become one of the largest food and medicine producers in the world. Much of this research occurs in scientific laboratories where biological, agricultural and food technicians are employed. Biological, agricultural and food Technicians set up, operate and maintain laboratory instruments, monitor experiments, make observations, calculate and record results view more

From the foods we eat, to our clothes, furniture and automobiles, chemicals play a large role in our lives. Chemical engineers convert scientific discoveries into marketable products. Chemical engineers are involved in many aspects of; chemical production, research and design, as well as, in the construction and operation of industrial plants. They conduct research to develop new manufacturing processes, analyze operating procedures, equipment and machinery functions and make recommendations for reducing processing time and cost view more

Whether the product is photographic film, pesticides, prescription drugs, or food, the chances are that it uses one of the 50,000 different chemical substances manufactured by workers in the chemical industries. Operating from a control booth, chemical plant and systems operators use gauges and computer readouts to monitor and control the entire production process. They make sure that chemicals are mixed in the correct ratios, and that reaction rates, temperatures, and many other variables are on target view more

If you’re fascinated by the intricate science of chemistry, you may want to consider a career as a Chemical Technician. Chemical Technicians work in laboratories and manufacturing facilities. They work with-scientists to study various substances, with applications ranging from a new product development…to a major medical breakthrough. Some collect and analyze air and water samples to monitor pollution levels view more

Chemicals make up our world. Some are natural. Some are made by humans—synthetic. But each chemical has its own particular way of behaving under changing conditions such as heat, exposure to light, and combination with other substances. Chemists study how chemicals affect each other, and how they interact with the environment. Usually they specialize in a particular kind of chemistry. They use their knowledge to contribute to many different fields, from energy development to medicine and food processing view more

Pollution is a major problem in today’s world. But we can breathe a little easier if Environmental Engineering Technicians are on the job. Working with environmental engineers and scientists, these technicians test the air, water and soil for pollution. This involves setting up and monitoring sophisticated equipment. If findings indicate that pollution levels need to be further investigated, these technicians become environmental detectives view more

There is a price any society pays for progress. Often, that price is measured in damage to our environment or the public health. Environmental Scientists and Specialists, including health specialists, try to stop the damage. These specialists investigate what’s causing the pollution or health hazard. They may perform laboratory and field tests to monitor environmental resources and determine the contaminants and sources of pollution view more

Before motion picture footage can be edited into a film, it has to be processed, prepped, transferred and digitized into an editing system. Film laboratory technicians process and prep the film for that transfer. These workers are involved in many tasks in a film processing facility, and may specialize. While it helps to have a discerning eye, some lab techs rely more on their sense of touch -- working comfortably and accurately in complete darkness! In order to show you this, we're simulating the procedures with the lights on view more

If you enjoy working with your hands, you know how rewarding it can be to create something as beautiful as it is functional. And that's just what furniture finishers do. They are skilled workers who apply chemical coatings to enhance and highlight the beauty of wood furniture. They use hand or power tools to painstakingly prepare the surface. Using brushes or spray guns, they stain, paint or seal the surfaces view more

Gas is a product of nature. But it takes a lot of technology to extract gas from nature, and to distribute it for use in industry and homes. Gas Plant Operators are responsible for performing these tasks safely and efficiently. For example, they’re in charge of complex equipment that extracts nitrogen and oxygen from the air. Or they might be in a plant that liquefies, compresses, or re-gasifies natural gas view more

The first century of the Industrial Revolution left a legacy of hazardous waste that government and environmental experts are trying to clean up. Hazardous Materials and Waste Technicians are at the forefront of this effort. Some hazardous waste technicians work on-site; others, in a hazardous materials center, called a “hazmat facility.” There, they perform a variety of tasks including transportation, treatment and storage of hazardous wastes view more

Many jobs carry an element of risk. Through the years, however, the United States has tried to make even the most dangerous places to work as safe as possible. Industrial Safety and Health Engineers are responsible for making sure workplaces meet the requirements of laws designed to protect people. They promote worksite or product safety and health by applying knowledge of industrial processes, as well as mechanical, chemical and psychological principles view more

The world’s demand for oil and natural gas is unceasing. To find new supplies of these vital resources, we depend on petroleum engineers. They search the world for reservoirs containing oil or natural gas, and work with geologists and other specialists to extract it. This is not a simple matter of plunging a drill into the ground. First, the team develops a map of the underground, and devises a drilling method, designing equipment and processes for that particular target—whether it be under a mountain, under a desert, or under the ocean view more

An oil refinery is a type of factory where crude oil is broken down into various components, and then recombined into new products…such as gasoline and jet fuel. A team of refinery technicians oversees this process. Refinery operators direct and control the continuous processes in petroleum refining. They're alert to any glitches in the system that might require immediate repairs to avoid damage to the quality and quantity of the product view more

There was a time when successful sales representatives needed only a smile, a shoeshine, and a case-full of samples. But today, sales reps have to know a great deal about the technical details of their products--and those of the competition. When selling products such as computers, lasers, microchips, software, space-age plastics, new drugs or chemical compounds, technical sales reps often find themselves on the leading edge of science and technology view more

It's a dirty job, but somebody's got to do it -- and soil scientists do. They study the properties of soil -- all types of soil -- to help agriculture and other industries use it effectively. Soil scientists split their time between farms and agricultural research stations where they survey and collect soil samples…and laboratories where they use specialized equipment to analyze those samples view more

Water, water, everywhere: but it is safe to use? Water & Waste Treatment Plant Operators treat water so it's safe to drink, while Waste Treatment Plant Operators remove pollutants and other harmful materials from wastewater, making it safe to return to the environment. Water and Waste Treatment Plant Operators read gauges and meters and use computers to make sure that the equipment is operating properly view more
