Contain the Spill
- Check for contamination on yourself or your co-worker.
- Remove contaminated clothing and place in a plastic bag. Paper suits are available.
- Wear lab coat and two pairs of gloves for decontamination. Change gloves frequently.
- Wear cover shoes or plastic bags bound with electrical tape or elastic bands around the ankles to prevent spreading the contamination.
- For dry contamination on yourself, use masking or adhesive tape to remove it
- For wet contamination on yourself, use mild soap and rinse with lukewarm water taking care not to spread the contamination. If this fails, consult Radiation Safety to find suitable solvent.
- Don’t rub skin harshly as this may cause skin damage.
- Once you are convinced that you have removed any contamination from yourself, begin to assess the area
- Determine the extent of the area contamination with a monitor or wipe tests.
- Delineate the contaminated area with a grease pencil or flagging tape.
- Remove any broken glass with tongs or forceps.
- Soak up liquid spills with “diapers”. Use wet paper towels for dry spills.
- Use Count-Off™ spray for decontamination, working from the outside to the centre of the spill.
- Test for residual activity using the survey meter or swipe tests.
- Repeat process of decontamination until the area is clean or swipe tests yield consistent results.
- Place decontamination materials in a plastic bag. Seal and label the bag with a waste tag and note the tag number in the inventory sheet.
- Monitor the persons involved in the decontamination as well as yourself for personal contamination. Remember to check the soles of shoes
Secure the Area
- Secure the area against further access with flagging tape.
- Post Radiation Warning Signs.
- Do not resume work until the area is assessed by Radiation Safety Staff
- Complete Incident Report Form and forward to Radiation Safety
Reporting of Spills and Incidents to the CNSC
- Radiation Safety is required to report immediately any spills or incidents to the CNSC that involve more than 100 Equivalent Quantities, personnel contamination or the release of volatile material
- If an exposure occurs that is in excess of the applicable radiation dose limits, Radiation Safety must contact the CNSC within 24 hours of the occurrence.
