Safe and Vault Services Flashcards

Which drilling technique for opening a safe targets the drill point directly above or through the combination dial to access the wheel pack?

Answer: Nose drilling (direct drive drilling through the dial spindle area)

Nose drilling targets the spindle area behind the combination dial to access the wheel pack and either read positions with a borescope or destroy the lock's bolt-blocking mechanism.

What is the function of a 'day-lock' or 'relocking feature' on a high-security safe?

Answer: Allows the safe to be quickly closed and re-locked without requiring the full combination during business hours

A day-lock (or day gate) allows staff to close the safe and re-lock it in a latched position accessible with a simple motion, without requiring the full combination until end of day.

What is a 'gun safe' rated to and how does that differ from a UL-listed burglary safe?

Answer: Gun safes are typically not UL burglary rated and offer basic storage security, while UL safes meet independently tested standards

Most consumer 'gun safes' are not UL burglary rated and only provide basic security against opportunistic theft; true UL-rated burglary safes are tested to specific attack resistance standards.

Which fire rating classification indicates a safe has been tested to protect paper documents (ignition point ~350°F) for 1 hour?

Answer: UL Class 350-1 Hour

UL Class 350 fire safes are tested to keep the interior below 350°F (the ignition point of paper) for the rated duration (e.g., 1 hour) when exposed to external fire.

What is the correct way to change a combination on a dial combination safe lock?

Answer: Follow the lock manufacturer's specific procedure, typically dialing to a change index position, inserting a change key, and re-dialing the new combination

Changing a combination requires the manufacturer's specific procedure using a change key (or change index), which temporarily unlocks the wheel mechanism so new gate positions can be set.

What is a 'time lock' on a vault?

Answer: A mechanism that prevents the vault from being opened until a preset time has elapsed, regardless of whether the correct combination is dialed

A time lock is a clockwork mechanism inside a vault that prevents the bolt work from being retracted until the preset time has elapsed, defending against forced combination extraction after hours.
