Spill or Leakage: Key StepAction Required1Cordon of the areaUse the red/white tape in the spills kit and contact the RPS immediately2If aerosol has been released - EvacuateEvacuate the room and on the way out turn the fume hoods on and if able open the window if it can be done quickly3If not don't walk the contamination out of the labStay in the room unless dose is >7.5Sv/h. Before you leave put down a tacky-mat on the floor at the door & walk out over it. Monitor shoes and lab coat and remove them if contaminated4Deal with the contaminated person first Change own gloves for a fresh pair!Flush any cuts with water, clean the hands, check clothes, shoes & self for contamination. If found on shoes put on overshoes and go to the shower room. In the shower room put all contaminated items in the red bags provided & wait for RPS advice5Decontaminate the area from outside to in First drop absorbent tissues onto the contamination to stop further spread then wipe it up. Next wipe an area of 1m radius around the spot - from the perimeter back towards the centre  Note: If sealed sources are used and one is found to be leaking contact the Main campus Safety Office on extn 13402 ASAP and the local RPS. If disabled people work in this area the PEEP (Personal Emergency Evacuation Plan) should be included in this appendix or a reference to where it is kept recorded. Contamination: Key StepAction Required1Cordon of the areaUse the red/white tape in the spills box and contact the RPS immediately2Wear protection and use the correct monitorWear two gloves on each hand, eye specs, buttoned up lab coat and select the correct monitor for the isotope3Deal with the hotspot firstIf the hotspot is wet drop a dry tissue over it to contain it. If it is dry wipe it with a damp tissue held in tongs. Put the used wipes in the red bag provided.4Decontaminate from outside to inWipe an area of 1m radius around the hotspot from the perimeter back towards the spot. 5Confirm area is clear if not go back to step 3 above until it is Wipe the area to check for background cps, check gloves - if reading >twice the background replace the outer gloves with new ones and return to step 3.  Note: If several isotopes are being used in an area a list of appropriate monitors for each isotope being used should be displayed with the local rules. Fire:  Key StepAction Required1Return the source to its storage locationThis will limit the spread of airborne contamination during a fire and should only take a few seconds.2Tackle the fire if safe to do so if not Use the correct fire extinguisher for the fire - see guidance by fire extinguishers. 3Lock the room and Raise the alarmShout to other lab users in the area to vacate, lock the room then hit the break-glass fire alarm button in corridor4Go to assembly point immediatelyWhen outside If the fire was in your lab inform the fire warden of the lab location, nature of fire, the isotopes involved and leave your name.5Do not return to lab until the RPS says its safeWait until the RPS has checked the lab for airborne, room, door and other contaminations.  Personal injury: Key StepAction Required1Treat the injury first and call the local First Aider then the dept RPS Treatment of the injured person take precedence above all else. Encourage bleeding to clean the wound then wash contamination away from the wound.2If injury is serious call an ambulance and the school RPAGive the ambulance your name, the injured persons name, their location, nature of their injury, isotope involved & the lab number of the accident.3Contain the spill and decontaminate the areaOnly when the person is safe contain the spill and decontaminate the area. 4Monitor yourself, others and the rest of the labIf contamination is still found consult the contamination contingency plan for self and room decontamination and the RPS.5Fill in statutory accident form with the RPS  An accident report form must be filled in ASAP following any accident or incident. Loss of source: Key StepAction Required1Inform the RPS without delay & ask questionsGive the RPS details of when source was last seen or used and ask colleagues if anyone has borrowed it recently2Cordon of the area and halt the work.Use the red/white tape from the spills box. Suspend work, waste disposal, and lab cleaning and contact the Safety Office ASAP3Search the lab with an appropriate monitorSee list of monitors to use for each isotope then search bins, bags, boxed files, sinks, lab coats and people etc4Source not found call the Safety Office RPO or the RPA ASAPThis will trigger a formal investigation. If the activity lost exceeds the quantity in column 5, schedule 8 of IRR99 notify the Environment agency via the RPA or RPO ASAP.5Fill in statutory accident form with the RPS/RPA  An accident report form must be filled in ASAP following this incident stating this is an incident not an accident. What else should be in each lab? Each lab should ideally have a tacky-mat and an emergency spill kit containing at least the following items: Radiation hazard warning tape and labels, pen, scissors, tweezers, specs, overshoes, tissues, bottle of Decon-90, 100L red bin bags and smaller ones, instruction booklet with wipe-clean summary cards to guide users on how to do the decontamination. Designated sinks, hoods, benches and storage location should be labelled with appropriate radiation warning signs or radiation hazard tape. Each lab should have the correct beta, X & gamma monitors (annually calibrated) for the isotopes being used and a wipe-test kit plus monitoring records for Tritium use. Remember monitoring records are a statutory, not an optional, requirement for a radiation area. Finally a deputy RPS should be available when the main RPS is absent so that any waste bags in the department do not exceed the 30 days storage limits and contingency plans can be acted upon in case a real emergency occurs.
