    What chemical equipment operators and tenders do

    Job Zone 2: Some preparation

    Operate or tend equipment to control chemical changes or reactions in the processing of industrial or consumer products. Equipment used includes devulcanizers, steam-jacketed kettles, and reactor vessels.

    Usually a high school diploma; some on-the-job training or experience.

    What the work is like

    Workers in this field run and monitor machinery like reactor vessels, steam-jacketed kettles, and devulcanizers to guide chemical changes. Daily tasks revolve around watching processes, inspecting equipment, getting information, and controlling machines. Operators must handle and move objects, drive mechanized devices, and document their work while communicating with team members and supervisors.

    This role suits people with realistic interests who enjoy hands-on, practical tasks. Success requires strong skills in operation and control, operations monitoring, reading comprehension, and critical thinking. Operators must apply knowledge of chemistry, production processes, mathematics, and mechanics. Key work styles include cautiousness, attention to detail, dependability, and stress tolerance to ensure safety and precision when handling chemical reactions.

    How to get there

    Entering this field typically requires a high school diploma. Because this career is classified under O*NET Job Zone 2, most workers need some preparation, which usually includes a high school education combined with on-the-job training or previous work experience.

    Students interested in this career often study physical science technologies or technician programs in college. To build their qualifications, operators can pursue professional certifications. Available credentials include the Coating Inspector Program - Level 1 and Level 3 Peer Review, or the Protective Coating Technician certification, all from the Association for Materials Protection and Performance. Other options include the Piping Inspector Certification and the Pressure Vessels Inspector Certification from the American Petroleum Institute, as well as the Veriforce PEC H2S Clear for Energy certification.

    Pay and outlook explained
