Question 1

Which postural analysis tool uses a scoring system that categorizes body regions into Group A (trunk, neck, legs) and Group B (upper arm, lower arm, wrist) to assess musculoskeletal risk?

Accepted Answer

REBA

Answer

REBA (Rapid Entire Body Assessment) divides the body into Group A (trunk, neck, legs) and Group B (upper arm, lower arm, wrist) to generate a risk score.

Question 2

When performing a NIOSH Lifting Equation analysis, what does a Lifting Index (LI) value greater than 1.0 indicate?

Accepted Answer

The lift exceeds recommended weight limits and poses elevated injury risk

Answer

An LI greater than 1.0 indicates that the recommended weight limit is exceeded, increasing musculoskeletal injury risk for some workers.

Question 3

In ergonomic evaluation, the term 'anthropometry' refers to which of the following?

Accepted Answer

Scientific measurement of the human body and its dimensions

Answer

Anthropometry is the science of measuring the size, shape, and proportions of the human body to inform ergonomic design.

Question 4

A job requires sustained pinch grip force exceeding 2 kg for more than 10% of the work cycle. According to ergonomic risk criteria, this task would be classified as:

Accepted Answer

High risk requiring priority ergonomic intervention

Answer

Sustained pinch grip forces above 2 kg for significant portions of the work cycle are classified as high ergonomic risk requiring prompt intervention.

Question 5

Which of the following best describes the concept of 'neutral posture' in industrial ergonomics?

Accepted Answer

The posture in which joints are positioned at mid-range, minimizing stress on muscles and tendons

Answer

Neutral posture places joints at mid-range positions, reducing mechanical stress on muscles, tendons, and nerves.
