Injury Prevention & Risk Management Flashcards

A plant recorded 10 OSHA-recordable injuries over 400,000 employee hours worked. What is its Total Recordable Incidence Rate?

Answer: 5.0

Incidence rate = (10 × 200,000) / 400,000 = 5.0 per 100 full-time workers.

What load constant does the Revised NIOSH Lifting Equation use as the starting point for the Recommended Weight Limit?

Answer: 23 kg (51 lb)

The load constant is 23 kg (51 lb), the maximum recommended weight under ideal lifting conditions.

Under the Revised NIOSH Lifting Equation, a Lifting Index greater than which value means the task carries increased risk of low back pain for some workers?

Answer: 1.0

An LI above 1.0 indicates elevated risk for some of the workforce, and the risk keeps rising as the LI increases.

Warehouse workers lift 18 kg cartons from pallets on the floor. Which intervention ranks highest in the hierarchy of controls?

Answer: Redesign the process so cartons arrive on a conveyor at waist height

Removing the floor-level lift through redesign is elimination/engineering, which is more effective than administrative controls or PPE.

What is NIOSH's position on using back belts to prevent lifting injuries in uninjured workers?

Answer: There is insufficient scientific evidence that they prevent back injuries

NIOSH concluded there is not enough evidence that back belts reduce injury risk, so it does not recommend them as a control.

Under OSHA recordkeeping rules, which treatment for a work-related wrist strain makes the case recordable?

Answer: Prescribing a prescription-strength anti-inflammatory medication

Prescription medication counts as medical treatment beyond first aid, so the case must be recorded.

When designing a job rotation schedule to reduce MSD risk, what is the most important factor?

Answer: Rotating between tasks that load different muscle groups and body regions

Rotation only gives recovery when each task in it stresses different tissues.
