1. We would like to know if at your site if you survey your safety harnesses after every use? All tools including safety harnesses are surveyed upon return to the tool room. We have a SAM set up for this survey. Any tools / harnesses that alarm the SAM are segregated and surveyed by a technician 2. Is it different if used in clean versus contaminated areas? Yes, harnesses used in a c-zone must be released to the RCA by a technician prior to going back to the tool room 3. If you don't survey the harnesses after every use, what frequency or reason would require a survey? All surveyed 4. What instruments do you use to survey your safety harnesses? For those used in a C-zone frisker smears and a SAM. For those used in the RCA just the SAM unless they alarm 5. For the safety harnesses used in contaminated areas, how often do you smear the harnesses? Surveyed periodically during the shift 6. Are your contaminated safety harnesses staged in contaminated areas for use in outages? Non-outages? Infrequently on line. During outages we have some that are left in C-zones.

We survey the safety harness after every use by taking a smear and monitoring in our article monitors, followed by frisking if we receive an alarm. The alarm set points we use for contaminated area safety harnesses is 10K dpm, and clean area is 1K dpm. 7.
