Report these to your supervisor.Employers must ensure that workers are trained and follow this safe work procedure.Steps to complete this task safely:Ensure proper PPE is donned before starting this procedure.Disassemble contaminated equipment and prepare it for decontamination.Dissolve two tablespoons of Alconox or Sparkleen in water to make a paste.Using disposable paper towels, apply the paste and start with washing and wiping the area/equipment. If this does not remove the contamination, move onto scrubbing, abrasion and/or corrosive techniques, in that order. DO NOT use techniques such as grinding, sanding, scrapping or chipping of contaminated surfaces.Best practice is to start washing and wiping at the edge of the contaminated area and work towards the area of highest contamination. If a highly contaminated area is creating unacceptably high levels of radiation, clean this area first. Otherwise, follow the former procedure.During the cleaning process, frequently monitor the contaminated area with either a direct reading instrument or SWIPE TEST to determine the effectiveness of the cleaning procedure. Adjust the cleaning method and or continue to decontaminate as necessary. Upon completing the decontamination procedures listed, remove gloves and wash hands thoroughly. Continue to monitor hands, body and clothing for radioactive contamination. Dispose of gloves and all other contaminated materials into a designated, properly labelled, radioactive container.Any equipment and areas that cannot be decontaminated must be identified and controlled as radioactive material. This may require appropriate shielding.ReferencesRadiation Safety, University of CalgaryRadiation Safety (Duties of Personnel and Emergency Procedures), Thompson Rivers University ................
