Which assessment method categorizes manual handling tasks into red, amber, and green risk bands using a simple filter approach?
Answer: MAC (Manual Handling Assessment Charts)
The UK HSE Manual Handling Assessment Charts (MAC) use a color-coded risk banding system to quickly categorize lifting, carrying, and team-handling tasks.
A job rotation schedule is evaluated ergonomically by ensuring that rotated tasks target:
Answer: Different muscle groups and body regions to allow recovery
Effective job rotation alternates tasks that load different muscle groups and body regions, allowing stressed tissues to recover while the worker remains productive.
When validating a workplace ergonomics intervention, the MOST objective outcome measure for upper-extremity disorder risk reduction is:
Answer: Pre- and post-intervention RULA or REBA scores
Comparing validated observational tool scores (e.g., RULA, REBA) before and after an intervention provides an objective, quantified measure of postural risk change.
The Composite Strain Index (JSI) multiplies six task variable scores; which variable addresses the proportion of the work cycle during which exertion occurs?
Answer: Duration of exertion per cycle (DE)
Duration of exertion per cycle (DE) in the Strain Index reflects what percentage of each work cycle the worker is actively exerting force.
During a thermal environment assessment in a hot warehouse, which instrument directly measures the radiant heat component of the WBGT index?
Answer: Globe thermometer
The globe thermometer (a black copper sphere with a thermometer at its center) integrates radiant heat from surroundings with air temperature, contributing to the WBGT calculation.
An ergonomics checklist completed by a trained observer differs from a self-assessment checklist completed by the worker primarily in that:
Answer: Observer assessments capture actual postures and forces; self-assessments capture perceived demands and discomfort
Trained observer checklists document objective physical exposures, while worker self-assessments reflect subjective perceived effort, discomfort, and psychosocial factors.
In the context of ergonomics program evaluation, 'leading indicators' are metrics that:
Answer: Predict future risk by tracking proactive safety activities such as assessments completed
Leading indicators measure proactive activities (e.g., number of assessments conducted, employee training hours) that predict future injury reduction rather than reflecting past events.
