Which of the following statements identifies key considerations for laboratory workstation design?

• A. Bright lighting and loud alarms
• B. Short breaks every 6 hours
• C. Pipetting posture, microscope work, bench height, chair support, and accessible equipment placement
• D. Only using desktops without chairs

Answer: (C)

Ergonomic design of a laboratory workstation aims to minimize musculoskeletal strain and support efficient work. The best statement reflects practical, hands-on factors that affect how you interact with tools and surfaces: how you hold and move when pipetting to keep wrists and elbows in neutral positions; ensuring microscope work is done with a comfortable neck and back posture; choosing a bench height that puts your elbows at about a right angle without hunching; providing chair support to maintain proper lumbar alignment; and arranging equipment so you don’t have to reach, twist, or twist awkwardly during tasks. These elements together create a setup that protects your body while enabling precise, efficient work.

Other options miss the focus on how the physical layout and furniture affect body mechanics and workflow. Bright lighting and loud alarms are environmental considerations rather than how the workstation is arranged; short breaks pertain to scheduling rather than design; using desktops without chairs ignores essential ergonomic support and can lead to discomfort and injury.
