Inspecting and monitoring in person means noticing what's off with your own eyes, ears and hands, and being accountable for calling it.
Part of Test characteristics of materials or products, under the O*NET work activity group Inspecting Equipment, Structures, or Materials. Individual tasks below can carry a different label when their own wording calls for it (0 AI-ready, 0 AI-assist, 20 stays human).
Tasks built on this activity
- Examine samples to verify qualities such as clarity, cleanliness, consistency, dryness, or texture.
- Test samples to determine viscosity, acidity, specific gravity, or degree of concentration, using test equipment such as viscometers, pH meters, or hydrometers.
- Examine materials, ingredients, or products visually or with hands to ensure conformance to established standards.
- Test product samples for specific gravity, chemical characteristics, pH levels, concentrations, or viscosities, or send them to laboratories for testing.
- Test boiler water quality or arrange for testing and take necessary corrective action, such as adding chemicals to prevent corrosion and harmful deposits.
- Examine or test samples of processed substances, or collect samples for laboratory testing, to ensure conformance to specifications.
- Test samples of materials or products to ensure compliance with specifications, using test equipment.
- Examine materials, ingredients, or products, visually or with hands, to ensure conformance to established standards.
- Check arriving materials to ensure that they match purchase orders, submitting discrepancy reports as necessary.
- Test gas, chemicals, and air during processing to assess factors such as purity and moisture content, and to detect quality problems or gas or chemical leaks.
- Test solutions used to process textile goods to detect variations from standards.
- Draw samples for laboratory analysis, or test solutions for conformance to specifications, such as acidity or specific gravity.
- Perform tests to check the qualities and grades of products, such as assessing levels of bottom sediment, water, and foreign materials in oil samples, using centrifugal testers.
- Test samples of materials or products to ensure compliance with specifications, using test equipment.
- Inspect or test raw materials, parts, or products to determine compliance with environmental standards.
- Sample and test product characteristics such as specific gravity, acidity, and sugar content, using hydrometers, pH meters, or refractometers.
- Identify articles' fabrics and original dyes by sight and touch, or by testing samples with fire or chemical reagents.
Tasks where it is part of the work
- Draw samples of products and conduct quality control tests to monitor processing and to ensure that standards are met.
- Collect and test water and sewage samples, using test equipment and color analysis standards.
- Perform laboratory tests on samples collected, such as analyzing the content of contaminated wastewater.
