Spill Casualty

Question 1

Types of spills

Answer 1

Wet:

Dynamic- water flows

Static spill- water no longer escaping

Dry:

Dry material spread across the surface

Risk of re-suspension and inhalation

Question 2

Article 803

used for response to spill

Answer 2

Stop spill

Warn others

Isolate area

Minimize exposure

Secure or redirect ventilation

Question 3

Stop spill

Answer 3

Upright container

considered stopped when material is sufficiently contained to prevent further spread

Wipe up small amounts of liquids with absorbent material

Avoid self-contamination

Question 4

Warn Others

Answer 4

Shout “There’s a spill here”

Notify RADCON and ELT’s

Follow ship’s emergency bill

Keep unnecessary personnel away from spill

Question 5

When isolating the area:

Answer 5

Keep personnel out of area to minimize contamination

close hatches

set boundaries (large enough to contain, not impede access)

Question 6

Minimize exposure

Answer 6

Moving to edge of affected area

Do not spread contamination by leaving area

Remove wet contaminated clothing, directed by ELT

Avoid hand to mouth

Question 7

Redirecting Ventilation

Answer 7

Minimize potential generation of airborne radioactivity
- prevents air from blowing particles across the spill into other compartments

Minimize spread of contamination
-HEPA filters ventilation systems can remove finely divided radioactive particles

• these filters must then be treated as radioactive waste

Question 8

Supplemental spill actions

Answer 8

Injured personnel are priority

Minor injuries-
Prevent internal contamination
minimize skin dose
control spread of contamination

Evac- First priority
wetted clothing removed
Decon

Determine extent of casualty
- Rad levels in affected area
- radioactivity in affected area
- take radiological control actions to recover from the casualty

Question 9

Supplemental spill Action

Samples

Answer 9

Swipes/Frisks w/ 304 probe

Air samples, 0.3 cubic meter Portable Air Sample at spill boundary
- 100ccm=1x10(-9) per ml

Question 10

Supplemental spill action

Counting station

Answer 10

MFR- 304
Survey Map
Swipes
Phone Talker

Question 11

Decontaminate Area

Answer 11

lowest to highest contamination

transition from casualty to CSCA with CPA

Perform surveys between decon efforts to asses effectiveness

Question 12

Dispose of RAM

Answer 12

in Yellow Polu plastic bags, anything being removed must be frisked upon exit

Final Survey

perform survey

must be less than 100 uuCi/100cm2

Staged in areas where radioactive spills are probable to occur

Yellow poly bags
Green poly bags (non-radioactive waste)
Tweezers
absorbent material
survey maps
PAS paper
barrier materials
signs
tape
