What furnace, kiln, oven, drier, and kettle operators and tenders do

Furnace, kiln, oven, drier, and kettle operators run heating equipment used in industries other than basic metal, plastic, and food processing. Typical processes include annealing glass, drying lumber, curing rubber, boiling soap, and removing moisture from materials. Work orders and instructions give the process specifications and production schedule, and the operator presses and adjusts controls to activate, set, and regulate the equipment. While the batch heats, they watch gauges and panel lights for deviations from standards, and they confer with supervisors or other operators to report malfunctions or settle production problems. Samples of processed material are examined or collected for laboratory testing, and gauge readings, test results, and shift production are written in a log. Autoclave operators and annealers are examples of the job titles. Operators also carry materials and products between work areas, by hand or with carts, handtrucks, or hoists. Lumber kilns, glass annealing ovens, and rubber curing units are among the equipment tended.

Typical entry: According to O*NET, a high school diploma or equivalent is the most common level of education reported by workers in this occupation.

Also called: Ager Operator, Annealer, Annealing Operator, Autoclave Operator, Automated Process Operator.

Median annual wage in each release, as published; a release without a published median has no point. The same numbers are in the table above.

BLS does not design OEWS as a time series: each release pools three years of samples, and occupational classifications, area definitions and estimation methods change between releases, so a difference between two releases is not a measure of change over time. The figures are shown as published, side by side, and nothing is computed from them. See how often OEWS is updated.
