CPI Drain Cover & Entrapment Prevention Flashcards

What safety device automatically shuts off the pool pump if a blockage is detected at a suction outlet?

Answer: Safety Vacuum Release System (SVRS)

A Safety Vacuum Release System (SVRS) detects a blocked drain and shuts off the pump within seconds to eliminate dangerous suction.

Under the VGB Act, what is the minimum required action if an existing pool drain cover is broken or missing?

Answer: Close the pool immediately until a compliant cover is installed

A broken or missing drain cover constitutes an immediate entrapment hazard, and the pool must be closed until a compliant replacement is installed.

What is the purpose of the 'unblockable drain' design concept in pool safety?

Answer: It creates a drain opening large enough that a single bather cannot fully obstruct it

An unblockable drain is sized so that a bather's body cannot fully cover and seal the suction opening, preventing body entrapment.

What should a CPI inspector do if they find a drain cover that is correct but has been installed at an angle, creating gaps?

Answer: Flag it as a safety deficiency requiring correction

An improperly seated cover with gaps can allow hair or limbs to enter the sump area, presenting an entrapment risk that must be corrected.

Which of the following is a recognized type of entrapment that anti-entrapment drain covers help prevent?

Answer: Evisceration entrapment

Evisceration entrapment — where a drain creates suction strong enough to cause internal injury — is one of the five recognized entrapment types addressed by drain cover standards.

How often should drain covers be inspected and tested for secure attachment in a public pool?

Answer: At least annually, or per state code — whichever is more frequent

Drain covers should be inspected at minimum annually (and per state schedule) to confirm secure attachment and absence of damage or loosening.
