19
Q

The NCR (national capital region) fire department, hazardous materials, team, consider

A

20
Q

What is the maximum dose limit for radiological dispersal device (RDD)for the cold zone?

21
Q

What is the maximum dose limit for radiological dispersal device (RDD)for the warm zone?

A

2 mR/hr- 10R/hr

22
Q

What is the maximum dose limit for radiological dispersal device (RDD)for the hot zone?

A

Over 10R/hr

23
Q

What is the maximum dose limit for radiological dispersal device (RDD)for absolute turn back ?

24
Q

Where should pencil and electronic dosimeters be worn ?

A

Outside of PPE on the core of the body to allow for reading in the hot zone

25
Q

How often should external dosimeters be read and reported?

A

Every 15 mins

26
Q

How often should dosimeter tracking forms be done ?

A

Every time a dosimeter is used

27
Q

What should be used to extinguish natural gas what is burning outside?

A

Nothing do not extinguish the fire. The situation is better handled by permitting the gas to burn instead of extinguishing it incurring the risk of sudden reignition period to prevent the fire from spreading to adjacent structures, hose down combustibles and notify communications division

28
Q

what materials are used for gas mains ?

A

Cast iron, steel, wrapped /coated steel, plastic piping

29
Q

What materials does washing gas use for service lines?

A

steel, wrapped/coated copper, plastic piping

30
Q

What is the system pressure for Washington gas transmission line?

A

60PSI to 300PSI

31
Q

What is the system pressure for washington gas distribution line?

A

1/5th psi to 60PSI

32
Q

What is the system pressure for washington gas low pressure line?

A

1/5th psi to 1/4th psi

33
Q

Where is the Washington gas natural fueling station?

A

1240 12th St. SE
fuel pressure at the outlet of the fueling nozzle is approximately 3000 PSI with emergency shutoffs located at different location for each application
