Answer: (A)

IDLH stands for Immediately Dangerous to Life or Health. This term is used to describe an atmosphere that could cause death or irreversible health effects, or would impair a person’s ability to escape from the danger. It identifies conditions so severe that only full, critical protections—typically SCBA or similar supplied-air respirators—should be used, and a safety buddy and rescue precautions must be in place. Understanding IDLH helps determine the appropriate respiratory protection and emergency procedures needed to operate safely in hazardous environments. The other phrases listed aren’t the standard terminology used in hazmat practice.
