It is imperative that you act quickly in the event of a spill of radioactive material.
Obtain assistance
- Verbally warn all other persons in the area.
- Obtain immediate assistance to contain and control the spill.
- Restrict unnecessary movement into and through the spill area.
- Ensure that your School Radiation Safety Officer is advised, and also advise UWA Safety and Health.
Treat injured / contaminated people first
- Attend to personal injuries first (first aid).
- Soak up any liquid contamination from skin and clothing with dry tissues.
- Make way to wash area, avoiding spreading the contamination further.
- Using a fresh set of gloves, remove any contaminated clothing.
- Decontaminate contaminated skin and/or eyes.
- Monitor progress of personal decontamination.
Contain the contamination
While attending to injured / contaminated persons and afterwards, ensure:
- protective clothing (lab coats, gloves, overshoes, safety glasses) is worn
- the contaminated area is identified and marked out to assist with the clean-up
- broken glass and sharps are collected (using tweezers) into a sharps container
- the spill is covered with absorbent plastic backed pads or paper towels
- a suitable radiation contamination monitor is used to assess the extent of the spill and to assist with the clean up.
Once situation is under control
- Complete area and equipment decontamination.
- Monitor levels of contamination remaining, if any.
- Package, label and dispose of radioactive contaminated wastes.
- Discuss with the Radiation Safety Officer any need for biological monitoring.
- Submit incident / accident report to UWA Safety and Health.
