In occupational health and safety assessments, certain measuring devices are essential for evaluating physical hazards that workers may encounter. Among these, the dynamometer, accelerometer, and goniometer are fundamental tools, each serving distinct purposes in assessing workplace risks and ensuring worker safety.

The dynamometer is a device that measures strength or force exerted by muscles or mechanical components. In workplace hazard assessment, dynamometers are primarily used to evaluate the physical capacity of workers to handle loads or to assess the force exerted during manual tasks. For example, they can measure grip strength to determine the risk of musculoskeletal injuries related to gripping or lifting activities. By establishing the maximum force a worker can exert, ergonomists can design tasks and tools that match worker capabilities, reducing strain and injury risk (Bernard, 1997). The dynamometer's use ensures that manual handling tasks are within safe operational limits, thus preventing musculoskeletal disorders.

The accelerometer is a device that measures acceleration forces in different directions. In occupational safety, accelerometers are extensively used to monitor movement patterns and assess exposure to whole-body vibrations or sudden impacts. For example, workers operating vibrating machinery or working in environments with frequent impacts may be fitted with accelerometers to evaluate vibration exposure levels. This data helps in identifying tasks that could lead to vibrational hazards, which are linked to conditions like hand-arm vibration syndrome or back injuries (Bovenzi, 2010). Continuous monitoring with accelerometers provides quantitative data for developing and implementing vibration controls and ergonomic interventions.

The goniometer is used to measure joint angles and ranges of motion. In workplace risk assessments, goniometers help evaluate ergonomic hazards related to awkward postures, such as excessive bending or reaching. For instance, assessing the flexion or extension of joints during specific tasks can identify positions that may lead to musculoskeletal disorders. By quantifying joint angles, safety professionals can redesign workstations or modify task procedures to promote more natural postures, decreasing the likelihood of strain injuries (Chaffin et al., 2006). The goniometer's precision assists in detecting potentially harmful postures before they result in injury.
