What does the marker on a doorway indicate in entry procedures?

• A. Door Is Locked
• B. Hazard Present
• C. Area Is Ventilated
• D. Indicates Element Passed Through Doorway

Answer: (D)

Markers on doorways in entry procedures are meant to show that something has moved through that opening, creating a traceable record of passage. This helps keep track of who or what has entered and when, ensuring the next steps—such as decontamination, access control, or inventory checks—can be carried out correctly. It isn’t an indicator that the door is locked, that a hazard exists, or that the area is ventilated; its purpose is to signal that an element has passed through the doorway, supporting proper sequencing and accountability in the entry process.
