What is the role of the standby person during tank operations?

• A. Monitor personnel in tank
• B. Enter tank
• C. Operate pumps
• D. Record readings

Answer: (A)

In tank operations, the standby person serves as the safety observer outside the tank, whose main duty is to monitor the crew member inside. This role ensures continuous contact, watches for signs of distress or hazardous conditions, and is ready to raise the alarm or initiate rescue if anything goes wrong. They support the operation by keeping track of the entry, ensuring ventilation and atmosphere checks are in progress, and confirming that proper permits and safety procedures are followed. They do not enter the tank, operate pumps, or typically record readings themselves—their primary function is to watch and protect the person inside.
