00:00:01.500 --> 00:00:04.566
When you travel by airplane anywhere in the country, 

2
00:00:04.566 --> 00:00:07.499
the safety of every passenger and flight crewmember 

3
00:00:07.500 --> 00:00:11.533
depends on the work of transportation security screeners.  

4
00:00:11.533 --> 00:00:17.666
They screen passengers, baggage, and cargo to ensure compliance with federal regulations. 

5
00:00:17.666 --> 00:00:21.332
Transportation security scanners operate basic security equipment, 

6
00:00:21.333 --> 00:00:25.599
such as x-ray machines and hand wands, at screening checkpoints. 

7
00:00:25.600 --> 00:00:29.400
They inspect carry-on items for contraband, 
and search baggage by hand 

8
00:00:29.400 --> 00:00:32.333
when they suspect it contains prohibited items. 

9
00:00:32.333 --> 00:00:36.299
When necessary, these workers must test for explosive materials 

10
00:00:36.300 --> 00:00:39.933
using detection machines or chemical swab systems, 

11
00:00:39.933 --> 00:00:45.566
and notify supervisors or other safety personnel when security breaches occur. 

12
00:00:45.566 --> 00:00:48.799
They also confirm that passengers’ tickets are valid 

13
00:00:48.800 --> 00:00:53.366
and often deal with large numbers of people, sometimes in stressful conditions. 

14
00:00:53.366 --> 00:00:57.632
For passengers who trigger machine alarms or who are identified for searches, 

15
00:00:57.633 --> 00:01:01.499
the security screener performs pat-downs or wand searches. 

16
00:01:01.500 --> 00:01:07.166
Most transportation security screeners enter the field with a high school diploma or high school equivalency. 

17
00:01:07.166 --> 00:01:10.332
On-the-job training brings them up to speed on procedures. 

18
00:01:10.333 --> 00:01:15.266
Like most jobs in the security industry, a felony conviction may prohibit entering this field.
