Which symbol indicates that the equipment has been contaminated by a chemical, biological, radiological agent or infestation?

• A. Red X
• B. Red C
• C. Red Diagonal
• D. Red Dash

Answer: (B)

Hazard communication markings rely on a quick visual cue that flags a serious safety risk so you treat the item appropriately from the start. A red color paired with a letter that stands for Contaminated is used to show that the equipment has been exposed to a chemical, biological, radiological agent, or infestation. This designation tells you to stop normal handling, isolate the item, prepare for decontamination, and use the proper protective measures before any maintenance or movement. The other marks are used for different statuses or warnings and do not specifically communicate contamination, so they wouldn’t convey the need for decontamination and special precautions in the same way.
