Work environment. In O*NET's survey of workers in this occupation, the conditions most often placed at the two highest levels for crushing, grinding, and polishing machine setters, operators, and tenders are: wear common protective or safety equipment such as safety shoes, glasses, gloves, hearing protection, hard hats, or life jackets (100%), face-to-face discussions with individuals and within teams (99%), health and safety of other workers (83%), spend time using your hands to handle, control, or feel objects, tools, or controls (78%), exposed to sounds, noise levels that are distracting or uncomfortable (76%), determine tasks, priorities and goals (70%). Each percentage is the share of respondents choosing the top two levels for that condition (for example 'most of the time' or 'continually'), so it describes how common the condition is in the job, not how a particular workplace is (O*NET 31.0 Database, U.S. Dept. of Labor, ETA, CC BY 4.0).
