MEOC Research Methods & Evidence-Based Practice 3

Question 1

A company compares two excavator brands by reviewing independent third-party performance test reports. This approach is best described as:

Accepted Answer

Evidence-based equipment evaluation using objective data

Answer

Using independent third-party test reports to compare equipment is a core evidence-based approach that minimizes bias in decision-making.

Question 2

When an operator reads OSHA's excavation standard 29 CFR 1926 Subpart P, this document is classified as:

Accepted Answer

A primary regulatory source setting legally binding requirements

Answer

29 CFR 1926 Subpart P is a primary regulatory source that establishes legally enforceable excavation safety requirements in the US.

Question 3

After reviewing five years of maintenance records, an operator discovers hydraulic hose failures spike every spring. The evidence-based explanation most likely is:

Accepted Answer

Thermal expansion and contraction cycles during winter degrade hoses over time

Answer

Seasonal temperature cycling causes repeated stress on hydraulic hoses, leading to degradation patterns that appear in maintenance trend data.

Question 4

Which research method is most appropriate for determining if a new attachment type will fit and function safely on a specific mini excavator model?

Accepted Answer

Review the OEM auxiliary hydraulic flow specifications and attachment compatibility charts

Answer

OEM auxiliary hydraulic specs and compatibility charts provide the technical evidence needed to confirm safe attachment integration.

Question 5

An operator notices that near-miss incidents increase when visibility is reduced on overcast days. What is the correct evidence-based follow-up step?

Accepted Answer

Formally document the correlation and propose supplemental lighting as a control measure

Answer

Documenting the correlation and proposing an engineering control (supplemental lighting) is the evidence-based response to identified hazard patterns.
