CES Risk Management & Quality Assurance 4

Question 1

After a blast produces excessive fly-rock that damages nearby equipment, which is the FIRST step in a formal incident investigation?

Accepted Answer

Secure the scene and preserve physical evidence

Answer

Scene preservation is the critical first step — disturbing physical evidence before documentation destroys the factual basis for root cause analysis.

Question 2

OSHA's Process Safety Management (PSM) standard (29 CFR 1910.119) applies to explosives facilities when:

Accepted Answer

The facility meets threshold quantities of listed highly hazardous chemicals

Answer

PSM coverage is triggered when a facility holds threshold quantities (TQs) of OSHA-listed highly hazardous chemicals, which can include certain explosive precursors.

Question 3

A key performance indicator (KPI) used to measure QA effectiveness in an explosives distribution operation is:

Accepted Answer

Defective units returned as a percentage of units shipped

Answer

Return rate for defective product directly measures the quality of the distribution QA process — lower rates indicate better incoming inspection and handling practices.

Question 4

Which risk treatment option is employed when a blasting contractor purchases insurance for the blasting operation?

Accepted Answer

Risk transfer

Answer

Purchasing insurance transfers the financial consequences of a risk event to a third party (the insurer) — the risk itself is not eliminated.

Question 5

A Failure Mode and Effects Analysis (FMEA) assigns a Risk Priority Number (RPN) using which three factors?

Accepted Answer

Severity, Occurrence, Detection

Answer

RPN = Severity × Occurrence × Detection; this product ranks failure modes so engineering resources are directed to the highest-risk items first.
