CMSP Safety, Health & Risk Management 5

Question 1

What is the key distinction between a 'lagging indicator' and a 'leading indicator' in mine safety performance measurement?

Accepted Answer

Lagging indicators measure outcomes after incidents occur; leading indicators measure proactive safety activities

Answer

Lagging indicators (injury rates, fatalities) reflect past outcomes, while leading indicators (training completions, inspections conducted, near-miss reports) measure proactive safety activities that predict future performance.

Question 2

Which approach to safety management focuses on understanding what goes RIGHT in normal operations to build resilience, rather than only analyzing failures?

Accepted Answer

Resilience Engineering / Safety-II

Answer

Safety-II (Resilience Engineering) studies the variability in everyday successful performance to understand system strengths, complementing the traditional Safety-I focus on failures and accidents.

Question 3

Under MSHA regulations, what is the mandatory waiting period before re-entering an underground mine after a blast?

Accepted Answer

Until smoke and fumes have dissipated to safe levels and at least 15 minutes have elapsed

Answer

MSHA requires that re-entry after blasting be delayed until blast fumes and smoke have cleared and a competent person has examined the area, with a minimum time period specified in the applicable standards.

Question 4

A mine health and safety committee review finds that most injuries occur during the afternoon shift. Which analysis technique is most appropriate to investigate systemic causes?

Accepted Answer

Root Cause Analysis using the 5-Why method

Answer

The 5-Why Root Cause Analysis technique iteratively asks 'why' to drill past surface symptoms to the underlying systemic factors contributing to a pattern of incidents.

Question 5

What does the term 'imminent danger' mean under the Federal Mine Safety and Health Act?

Accepted Answer

A condition that could reasonably be expected to cause death or serious physical harm before it can be abated

Answer

Section 3(j) of the Mine Act defines imminent danger as any condition or practice that could reasonably be expected to cause death or serious physical harm before it can be abated.
