CTC Test Range Safety and Operations Flashcards

A CTC is conducting a structural test and an unplanned crack is observed in the test article. What is the immediate priority?

Answer: Call a hold, ensure personnel safety, and notify the Test Director and structural engineer before any further loading

An unplanned crack is an anomaly requiring an immediate hold to assess structural integrity and prevent potential catastrophic failure that could injure personnel.

What document establishes the formal safety requirements and constraints governing a CTC test on a US military test range?

Answer: The Range Safety Plan (RSP) or equivalent safety document approved by the range authority

A Range Safety Plan is the authoritative document that establishes all safety requirements, constraints, and responsibilities for test operations on a government range.

During a test countdown, the CTC discovers a test team member has not been medically cleared for the test day. What should the CTC do?

Answer: Hold the countdown and resolve the personnel readiness issue before proceeding

Personnel medical readiness is a GO/NO-GO criterion; unresolved readiness issues must be cleared before the countdown proceeds.

What is the purpose of a test facility Safety Data Sheet (SDS) review prior to a CTC test involving hazardous chemicals?

Answer: To ensure all personnel understand the hazards, handling requirements, and emergency procedures for chemicals in use

SDS review ensures personnel are briefed on hazards, required personal protective equipment, safe handling procedures, and emergency response actions.

A CTC test plan requires a test article to be pressurized to a level exceeding 10 psi. What additional safety measure is typically required?

Answer: A pressure system safety analysis and compliance with applicable pressure vessel codes (e.g., ASME) or range safety requirements

Pressure systems above defined thresholds require formal safety analyses and compliance with codes such as ASME or applicable DoD/range safety standards to prevent catastrophic failure.

Which principle does a CTC apply when deciding whether to proceed after an anomaly is observed during a test?

Answer: Conservative risk management: hold and investigate anomalies before proceeding, erring on the side of safety

CTCs apply conservative risk management, treating any anomaly as a reason to pause until its cause and safety implications are understood.
