111.06, HP EMERGENCY WORKER EXPOSURE CONTROL (EWEC) NPPERP (04/93)

EMERGENCY WORKERS EXPOSURE CONTROL (EWEC) t L PURPOSE AND SCOPE The purpose of this procedure is to establish the policy for controlling emergency worker exposure to ionizing radiation. This procedure is applicable to all off-site emergency workers under direction of the county involved in response to radiological emergencies.

II. RESPONSIBILITIES A. County Health Officer l The County Health Officer (CHO) will:

1. Alert, notify, and mobilize EWEC Desk personnel at an ALERT or higher classification.

2. Provide overall supervision and direction of exposure control activities through the Emergency Worker Exposure Control (EWEC) Desk '

Coordinator.

3. Provide directives for protective actions for emergency workers to minimize ,

exposure to radiation, including use of Potassium lodine (K]).

4. Authorize, as appropriate, emergency worker exposure in excess of the initial exposure guidelines.

5. Provide direction in the establishment of decontamination center (s) for emergency workers.

6. Ensure provisions for a 24-hour capability for exposure control activities.

7. Assign County Health Agency personnel to staff the EWEC Desk and >

ensure they are trained.

8. Ensure the coordination of the EWEC function during IPZ/ Recovery between the County EWEC Desk for County supported personnel and State EWEC at the DHS Dispatch facility (upon the activation of the FEOC).

B. Emernency Worker Exposure Control Desk Coordinator The EWEC Desk Coordinator will:

1. Supervise and coordinate the EWEC desk activities.

2. Review and follow the guidance provided in the EWEC Desk Checklist (EWEC-1).

1

111.06, HP-11 '- EMERGENCY WORKER EXPOSURE CONTROL (EWEC) _NPPERP

- (04/93)

3. Obtain an incoming FAX phone number from the Emergency Services '

Coordinator.

4. Ensure provisions for a 24-hour capability for exposure control activities.

C. Local Aaency/Oroanization Command Centers Command Centers will:

1. Follow the directives given by the EWEC Coordinator.

2. Review and follow the guidance provided in the Command Center Checklist (EWEC-2).

3. Ensure provisions for 24-hour capability are made for exposure control.

D. Emeraency Workers Emergency Workers (including volunteers) will: ,

1. Follow the directives given by their Command Center (s).

2. Review and follow the guidance provided in the Emergency Worker Exposure Control Checklist (EWEC 3).

Ill. CONCEPT OF OPERATIONS Exposure control of emergency workers is a multi-faceted activity. The primary responsibility for monitoring exposure lies with each individual emergency worker.

If an emergency of an ALERT or higher classification occurs, three groups will be directly involved in ensuring exposure controlis established. The three groups are:

The CHO and EWEC Desk,

The Command Centers of the individual County Departments and allied agencies l (i.e., Cities, Fire Districts),

e The emergency workers, themselves.

The EWEC Control Desk is the focal point for communications between emergency worker Command Centers and the CHO for exposure control purposes. The EWEC Desk is located at the County Emergency Operations Center in the Technical Support Room. The EWEC Desk will establish and maintain communications with the Command Centers of agencies with emergency workers. The CHO will provide directives to emergency workers, based upon the information from the Unified Dose Assessment Center (UDAC).

The EWEC Desk will document and maintain emergency worker exposure information called in by the Emergency Worker Command Centers. The EWEC Desk willinform the 2

111.06, HP EMERGENCY WORKER EXPOSURE CONTROL (EWEC) NPPERP l

, (04/93)

CHO of exposure trends and of exposures that approach the administrative and

emergency exposure guidelines. The CHO will ascertain protective measures and exposure authorizations for emergency workers and direct the EWEC Desk to i communicate protective actions and exposure authorization to the Command Centers, l Each agency that has been assigned exposure control equipment will activate a Command Center (CC). The Command Centers willissue radiation monitoring equipment and supplies to emergency workers. They will be the principal communication link .

between emergency workers and the EWEC Desk.

The Command Centers will record emergency worker exposures and report the exposures, if any, to the EWEC Desk. Additionally, they will also inform emergency ,

workers of the protective actions and exposure authorizations issued by the CHO. ;

Emergency workers will monitor and record their exposure while in the field. They will relay exposure readings to their respective Command Centers. When their exposure reading approaches any of the exposure guidelines, they will also contact their Command >

Centers. They should NOT exceed the exposure guidelines UNTIL CHO authorization is ;

given. They will contact the Command Center to report lost TLDs and non-operative SRDs.

Refer to FIGURE 1, Information Flow Diagram, for a depiction of how information will flow ,

in emergency worker exposure control activities.

W. EMERGENCY WORKER EXPOSURE GUIDELINES A. General-Exposure guidelines have been established by the County based on State and Federal guidance. All possible measures should be taken to maintain exposure as low as reasonably achievable (ALARA).

Whole body exposure guidelines can be determined in the field while thyroid doses cannot. The UDAC will determine projected adult thyroid doses and inform the CHO of field conditions and when the potential exists for emergency workers to exceed the established adult thyroid exposure guidelines.

Guidance for the CHO to follow in authorizing emergency exposures can be found in Attachment 4 of Checklist 2 of the CHO SOP. (111.05)

B. Exposure Guidelines :

Emergency exposure guidelines established by the County are based on State and Federal guidance. Exposure to radiation will be controlled and limited through procedures and policies contained in the County Emergency Plan.

!!!.06, HP EMERGENCY WORKER EXPOSURE CONTROL (EWEC) NPPERP (04/93)

1. Administrative Exposure Guideline:

The County has an administrative exposure guideline of 1 Rem (1000 mrem) whole body exposure for emergency workers. This guideline is 250 mrem below the lowest limit of the Emergency Exposure Guidelines (Sce Section 2 of Table 1). This administrative exposure guideline (limit) has been established to assure that emergency workers do not exceed the Emergency Exposure Guidelines without proper CHO approval.

If emergency worker exposures approach or exceed this administrative guideline of 1 Rem, the EWEC Desk willinform the CHO. The CHO will assess the need to remove emergency workers from areas where they could be exposed, or if the situation warrants, approve emergency workers to exceed the Emergency Exposure Guidelines listed in Section 2.

2. Emergency Exposure Guidelines Three categories of emergency exposure control guidelines, each with specific limits, are used to control emergency worker exposures. The Emergency Exposure Guidelines are as follows:

a. Emergency Operations (Initial Exposure Guidelines)

The initial guideline is 1.25 Rem, however, to ensure emergency workers do not approach this limit, CHO approval will be required to exceed 1 Rem.

Up to 1.00 Rem - Whole Body (without CHO authorization) .

1 Rem to 1.25 Rem - Whole Body (with CHO authorization)

1.25 Rem - 5.0 Rem - Whole Body (with CHO authorization)

This guideline is within those established for the general public (0.5 l

Rem - 5.0 Rem). Emergency workers are authorized to receive up to 1.00 Rom without CHO authorization. Exposure anticipated to be above 1.00 Rem must be authorized by the CHO.

l The EWEC Desk Coordinator willinform the CHO when emergency )

worker exposures approach this guideline. The CHO will evaluate ;

current emergency conditions and authorize exposures in excess j of this limit, as necessary. With authorization, emergency workers l may subsequently receive up to 5.0 Rem. Exposures above 5.0 1 Rem require further CHO consideration. l

b. Extraordinary Emergency Operations (Corrective and Protective Actions)

5.0 - 25 Rem (Whole Body) 4 l

!!!.06, HP EMERGENCY WORKER EXPOSURE CONTROL (EWEC) NPPERP (04/93)

This guideline is established for extraordinary circumstances where 3 there is the potential need for rescue operations, or when it is necessary to enter or remain in a known hazard area to mitigate the consequences of the emergency.

The CHO must authorize exposures above 5.0 Rem. Further authorization is required above 25 Rem. Exposures to emergency workers above the 5.0 Rem guideline will be on a volunteer basis.

c. Lifesaving Operations e up to 75 Rem (Whole Body)

This guideline has been established for situations involving the need to perform lifesaving activities. The CHO must authorize exposures above 25 Rem and planned exposures shall not exceed 75 Rem. This authorization is granted for lifesaving actions only and emergency workers performing such actions will do so on a volunteer basis.

Refer to Table 1, Emergency Worker Exposure Control Guidelines, for a listing in table format.

V. PROTECTIVE ACTION RECOMMENDATIONS FOR EMERGENCY WORKERS A. First Level Action: Protective Response At such time that anticipated or actuallevels of exposure exceed 1.25 REM, the CHO will consider recommending protective actions to emergency workers. The specific actions which will be considered include:

Donning protective clothing

Donning respiratory protection e Administration of Ki e Recall / relocation ;

Consideration will be given to taking protective actions under any one of the l following conditions: 1

1. Emergency workers self reading dosimeter (SRD) logs indicate an - ;

accumulated dose of 1 Rem or greater. ,

2. Detected and confirmed airborne or particulate radioactivity l

3. Survey meter readings by field teams in excess of 25 mR/hr.

5

a. Obtain a CDV-750 Dosimeter Charger and install a D-ce!! battery.

b. Place dosimeter on the charging coupler and hold down firmly.

c. Look into dosimeter and tum the knob slowly until the hairline comes into view, Then tum knob until the hairline is on or as near as possible to the right of zero. ;

d. Remove dosimeter and verify the hairline is on or near the zero. If not, repeat steps b&c.

i SECTION B - PRE-FIELD CHECKLIST AND PRECAUTIONS

1. Ensure dosimeters are charged and the initia! ' START' readings are written on the Field ,

Exposure Logs.

2. Ensure your name, address, agency, Social Security Number and TLD number (large number on bottom right of stick-on tab) are written on Logs. :

3. Ensure self-reading dosimeters and TLD are clipped between neck and waist on the front of ,

the body.

4. Ensure you are briefed on radiological conditions and communication methods by your ;

Command Center, before going on an assignment.

5. Remember- 1000 mi!!iRems are equal to 1 Rem (1 Rem == 1 Roentgen).

6. Handle dosimeters with care and keep them. DRY. Rough handling, dropping, and moisture can cause them to discharge and/or give inaccurate readings.

7. Follow protective action recommendations issued for emergencyworkers by the County Health Officer (CHO). (Most recommendations and advisories will be communicated to your !

Command Center and then to you.) ,

8. Do not take the Potassium lodide tablets unless directed to do so by the CHO. Read the leaflet provided in the kit if recommended to take the tablets. ;

SECTION C - RADIATION EXPOSURE TRACKING ,

Read self-reading dosimeters ohen, but at least hourtv. If the hairline begins to move up the scale, track your exposure as follows:

1. Ensure the initial start reading is recorded in the 'STARP column.

2. Record the ' TIME' and 'DATE* of each *ENDING* reading in the proper columns.

3. Record each reading in the 'ENDING* column. DO NOT RECORD ZERO READINGS.

4. Record the 'ENDING* reading in the next 'STARP reading columrt This number becomes your new 'STARP reading. (NOTE: If dosimeter has been recharoed. be sure to record the rm readino in the next ' START' column.)

5. Subtract the 'STARP reading from the 'ENDING' reading, and record the difference in the

NET

columrt ,

6. ADD the ' Net

to the previous TOTAL to get your new TOTAL exposure.

7. Inform your Commend Center when your TOTAL is 250 mR,500 mR,750 mR, and 1000 mR.

DO NOT EXCEED EXPOSURE LIMITS LISTED BELOWWITHOUT COUNTY HEALTH OFFICER (CHO) AUTHORIZATION. Inform your Command Center if you approach the limits.

8. Recharge your dosirneters if the hairline reaches three-fourths scale and at the beginning of ,

each shift. Record the new *STARP reading on the Log.

9. If your dosimeter hairline goes off-scale (cannot be seen), ask other workers in your area if their dosimeters are on-scale if their dosimeters are on-scale, your dosimeter is most likely malfunctioning and needs to be recharged or replaced. If other workers' dosimeters are also off-scale. immediately contact Vour Command Center for instructions.

10. If you lose any dosemeter or your SRD is non-operable, notify your Command Center IMMEDIATELY.

11. If you use all the spaces on a Field Exposure Log, get a new log from your Command Center On the new Log, record your last total in the space with the asterisk (*). Your next NET reading ,

will be added to this.

12. Tum in self-reading dosimeters at the end of each shift for use by others. Keep your TLD and all Exposure Record Loos until directed to tum them in.

13. Periodica!!y compare your exposure recorded on your Logs with the exposure recorded by un!rr r'nmmnnr1 Contor noenbo nnv, riienrennnric.c EMERGENCY WORKER ExoosURE GUIDEUNEs l Remember - 1 Rom = 1000 mRems (1 Rem = 1 Roentgen) )
