33
Q

How long can an attacker breach a key in knob lock with a pipe wrench or strap wrench?

A

1 minute.

34
Q

A

by using door sensors.

35
Q

What are natural targets of attack for external doors?

A

Hinge pins

36
Q

How can hinge pins be defeated?

A

Thermal tools or explosives.

37
Q

1 minute.

38
Q

Using hand tools, how long does it take to create a crawl through hole in plate, tempered, or wired glass?

A

15 seconds

39
Q

How long does it take to force apart louvers or mesh in doors?

A

30 seconds.

40
Q

What is the first step in upgrading a facility’s resistance to penetration?

A

eliminate unnecessary doors.

41
Q

What is the second step in upgrading a facility’s resistance to penetration?

A

eliminate unneeded windows, louvers, and external knobs and keyways.

42
Q

What can be done to prevent a door from being pried open?

A

weld or bolt a sheet metal strip called an astragal to the door.

43
Q

Why is annealed glass less desireablwe than other types of glass?

A

it breaks into large shards that can cause serious injury.

44
Q

What type of glass is treated to resist breakage?

A

Tempered Glass

45
Q

Why do building codes require tempered glass?

A

it breaks into small pieces rather than shards.

46
Q

What benefit does wired glass provide?

A

It provides some resistance against large objects.

47
Q

Where is wired glass typically requirred?

A

by fire codes in areas where they need to maintain fire ratings in a door.

48
Q

How is laminated glass composed?

A

two sheets f ordinary glass bonded to a middle layer or payers of plastic sheeting material.

49
Q

What is lanimated glass used for?

A

mitagating blast forces.

50
Q

What happens when laminated glass breaks?

A

it may crack or break, but the pieces tend to adhere to the plastic material.

51
Q

How is bullet resistant or burglar resistant glass composed?

A

laminated and consists of multiple plies of glass, polycarbonate, and other plastic films to provide many levels of ballistic resistance.

52
Q

how long does it take to penetrate standard glass?

A

59
Q

What does penetration tests suggest are effective additions to roofs?

A

barriers placed10 to 12 in. below the roof.

60
Q

Electric Security Fences come into what two forms?

A
  1. The all live-wire deterrent fence
  2. The monitored Fence.
61
Q

Monitored fences are usually integrated with what types of devices?

A

intruder alarm or access control systems and-increasingly-with surveillance cameras.

62
Q

What are blocking barriers typically used for?

A

To control or prevent vehicle access toa space.

63
Q

What are the two types of blocking barriers?

A

passive (fixed) and active (operable)

64
Q

What types of items are considered passive barriers?

A
  1. fixed bollards
    2, engineers’ planters
  2. Jersey Barriers
  3. heavy objects and trees.
  4. water obstacles
  5. walls and fences
64
Q

Where are active barriers located?

A

At vehicle access control points within a perimeter barrier system or at the entry to specific buildings within a site.

65
Q

How are Active Barriers typically operated?

A
  1. An attendant (security officer)
  2. electronic access control system (card reader or keypad)
66
Q

What types of items are considered active barriers?

A
