CPI CPI Drain Cover & Entrapment Prevention 2

Question 1

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

Accepted Answer

Safety Vacuum Release System (SVRS)

Answer

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

Question 2

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

Accepted Answer

Close the pool immediately until a compliant cover is installed

Answer

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

Question 3

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

Accepted Answer

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

Answer

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

Question 4

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

Accepted Answer

Flag it as a safety deficiency requiring correction

Answer

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

Question 5

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

Accepted Answer

Evisceration entrapment

Answer

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.
