Atmospheric-type tanks shall be equipped with which features to provide for inspection?

• A. Interior tank surfaces, and pump suction, relief, and testing line connections
• B. Interior tank surfaces; protected sight gauges or other liquid level devices
• C. Interior tank surfaces; connections for pump suction, relief, and testing line; protected sight gauges; and filling and draining connections
• D. Protected sight gauges or other liquid level devices

Answer: (C)

For atmospheric-type tanks used in foam-water systems, being able to inspect the interior and service the tank safely requires a combination of access, level indication, and service connections. The interior tank surfaces are provided so inspectors can directly examine the walls for corrosion, deposits, or damage and perform cleaning as needed. Protected sight gauges or other liquid level devices give a safe, readable indication of how much concentrate remains without exposing personnel to fumes or splashing, which is essential during inspection and maintenance. Connections for pump suction, relief, and a testing line ensure you can draw from the tank for testing and operation, vent any pressure or vacuum safely, and perform necessary hydrostatic or functional tests of the system. Filling and draining connections are necessary to fill the tank for inspection, maintenance, or testing and to drain it completely when needed for cleaning or discrete inspections. Together, these features support thorough inspection, safe operation, and proper maintenance of the tank.
