Phi Book 2 Mod 11

Front 1

List 4 purposes of job coverage

Back 1

1 to ensure that the workers radiation exposures are maintained ALARA and within guidelines and limits

2 to minimize the creation and spread of surface contamination

3 to minimize the creation and spread of airborne radioactive material

4. To minimize the creation of radioactive waste

Front 2

Explain the differences between continuous and intermittent or periodic job coverage

Back 2

-During continues job coverage the technician covers only one job and remains at the job site while work is being performed.

-For intermittent coverage the technician may cover more than one job performing periodic checks various work locations

Front 3

Give example conditions identify those conditions that should require job coverage

Back 3

1 radiation dose rates in the job area are high enough to potentially cause workers doses to exceed administrative control levels in a short time

2 radiation levels are expected to increase significantly during the job

3 entry into high radiation areas

4 The potential for spreading her level of contamination or causing airborne radioactivity

5 The potential for significant increase in contamination or airborne radioactivity levels of doing the job

6 Jobs performed by inexperienced workers

Front 4

Identify items that should be considered in planning job coverage

Back 4

1 determine exactly what workers will be doing not just replace a component but the details of whether grinding cutting or welding will be performed

2 review old surveys and talk with technicians who have previously cover the same or similar jobs do you anticipate any problem areas

3 review the area and system in which the work will be performed or talk with the workers to determine the potential Real logical consequences of the tasks associated with the job opening a Casca/container could create a contamination airborne radioactivity or cause radiation levels to change

4 Ensure that an adequate survey of the job area has been made

5 Review applicable post job ALARA reviews from previous jobs

Front 5

Identify examples of information that should be discussed with workers during pre-job briefings

Back 5

The technician or line supervisor informing workers of radiological conditions such as: dose rates, contamination levels ,and concentration of airborne Rado activity in the area. This should include an exclamation of the probable affect other job on radio logical conditions. Should include the method of communication to be used specifics about special dosimetry or protective clothing and actions of the technician covering the job. The RCT should cover what actions and exits to take an emergency reduce exposure and confusion question should be answered prior to starting work . The technician should emphasize radiological safety and importance of following the RWP

Front 6

Describe exposure control techniques that can be used to control worker and technician radiation exposure

Back 6

1 Wait in low-dose rate area as well not actually performing the job

2 periodically read or have workers read their dosimeters

3 use workers allowable dose and the dose rate in an area to determine the length of time worker can spend in that area

4 when using Time to control workers does an accurate record of the workers location with respect to the dose rate must be maintained

5 observe the location of a workers dosimetry with respect to the location of the radiation source

6 workers must leave temporary shielding in place unless they have been authorized to remove the shielding by radiological control

7 perform your survey as objects are being removed from their shipping container or cask do not wait until the radioactive objects are withdrawn to make a survey

8 keep workers from leaning across or over high sources of radiation possibly get them to move to the other side of equipment to do their work

9 prevent workers from picking up sources of radiation with their hands they should use pliers or tongs and carry items in a bucket or a plastic bag rather than in the hand

10 anytime casks containers or equipment are being open or open further than before recheck radiation levels including beta radiation levels

Front 7

Describe the in progress radiological surveys that should be performed in the industry under various radiological conditions as

Back 7

1 as specified by the technical work document(procedures) for the job

2 as described in the prejob briefing

3 as specified by the hold points for the job. These hold point steps Should be incorporated into the work package. these hold points will also be specified or referenced in the hold points Section of the radiological work permit

4 as required by the special instructions section of the radiological work permit

5 as required by radiological work permits procedures this instructs RCTs to perform surveys to monitor changing really logical conditions during the execution of a job

6 as specified by procedure routine and drop specific air monitoring program

Front 8

Describe the requirements for documentation of any progress radiological surveys

Back 8

1 Radcon daily log sheet or equivalent electronic log sheet

2 radiological survey report

3 airborne survey results

Front 9

Describe the requirements for documentation of in-progress radiological surveys

Back 9

1 Radcon daily log sheet or equivalent electronic log sheet

2 radiological survey report

3 airborne survey results

Front 10

Explain actions that should be taken if surveys show radiological condition significantly different from that expected

Back 10

1 stop the job

2 Stage workers in a low background location

3 Check electronic dosimeters

4 investigate source of radiological hazard

5 notify supervision

6 develop recovery plan

Front 11

Describe contamination control techniques that can be used to limit or prevent personnel and area contamination and or reduce radioactive waste generation

Back 11

1 Watch the workers point out and correct any work habits that could spread contamination

2 System components that are being repaired should be wiped down and drain to before the system is opened

3 ensure that workers follow procedures for removing material from a radiological area

4Ensure that workers follow proper procedures to minimize contaminating tools and equipment

5 Watch for the movement of crane rigging air or water hoses electrical leads and extension cords into and out of contaminated areas

6 electrical lines and hoses going into contamination areas should be secured taped down to eliminate the possibility of movement in or out

7 have workers remove their outer layer of protective clothing glove shoes covers and coveralls a few feet prior to the step off pad area

8 reduce the creation of radioactive waste

Front 12

Describe job coverage techniques that can be used to prevent or limit the spread of airborne radioactive material

Back 12

1 look for any actions that could create airborne radioactivity

2 take air samples during jobs in highly contaminated areas or at steps opening a system to change HVAC filters that could create airborne radioactive material during a job

3 use a CAM during performance of a job that is likely to great airborne radioactivity

4Ventilate enclosed areas

Front 13

Describe overall job control techniques in maintaining control of radiological work

Back 13

1Establish worker trust and confidence

2 during job coverage the technician should keep workers within their line of sight if possible

3 keep in contact with the workers

4 remind workers that casks containers or systems are not to be opened or work techniques change without notifying Radiological controls

5 when an individual work habits must be corrected after the quick method as advice or help

6 show positive helpful attitude toward coworkers

7 Do not overreact to situations when there is time for levelheaded solutions

Front 14

State reasons to stop radiological work activities in accordance with RCM

Back 14

1In adequate radiological controls

2 Radio logical controls not being implemented

3. Radio logical hold points not being satisfied

4 Alarming dosimetry or unexpected dosimetry readings

5workers disobeying procedures or not following the RWP

6 dropped container incident/spills

7 unexpected does rates or surface contamination readings

8 stop the unsafe work activities and that of any other individuals in the area who may be affected by the situation

9 clear all at risk person off in the area and post personnel to warn others trying to enter the area

10 inform all affected personal of the reason for the work stoppage including the process owner and immediate management responsible for the work

11 inform your foreman supervisor or manager of the situation
