Cooling and freezing equipment operators and tenders run equipment that cools or freezes food, blood plasma, chemicals, and other items. They operate cooling equipment such as refrigerators, batch freezers, and freezing tunnels. These workers monitor gauges and adjust controls to keep conditions within optimal ranges. They assemble equipment, start machines, stir material, and correct machinery malfunctions. Workers may need to weigh packages of frozen products. They also record temperature information, the amount of materials processed, and note any test results on report forms. Workers in this field are likely to be exposed to hazardous materials and extreme temperatures, so they typically wear safety equipment much of the time. There are no specific education requirements, although professional certifications may be helpful for applying to some positions.
